Answer:
6b + 5n = 101
Step-by-step explanation:
The correct system of equations that can be used to find b, the number of bracelets Ily sold, and n, the number of necklaces she sold is:
b + n = 18
6b + 5n = 101
In this system, the first equation represents the total number of items sold, which is 18. Since b represents the number of bracelets and n represents the number of necklaces, the equation b + n = 18 reflects that the total number of bracelets and necklaces sold should add up to 18.
The second equation represents the total amount of money Ily earned from selling bracelets and necklaces. Since bracelets were sold for $6 each and necklaces for $5 each, the equation 6b + 5n = 101 represents the total amount of money earned, which is $101.
Therefore, the correct system of equations is:
b + n = 18
6b + 5n = 101
For a project in statistics class, a pair of students decided to invest in two companies, one that produces software and one that does biotechnology research. Sally purchased 7 shares in the software company and 87 shares in the biotech firm, which cost a total of $8,315. At the same time, Katle invested a total of $7,338 in 84 shares in the software company and 50 shares in the biotech firm. How much did each share cost?
The cost of one share in the software company (x) is $32, and the cost of one share in the biotech company (y) is approximately $93.
Let's denote the cost of one share in the software company as 'x' dollars and the cost of one share in the biotech company as 'y' dollars.
According to the given information, Sally purchased 7 shares in the software company and 87 shares in the biotech company, which cost a total of $8,315. We can express this as the following equation:
7x + 87y = 8315 ----(Equation 1)
Similarly, Katle invested a total of $7,338 in 84 shares in the software company and 50 shares in the biotech company. This can be represented as the following equation:
84x + 50y = 7338 ----(Equation 2)
To solve this system of equations, we can use the method of substitution or elimination. Here, we will use the elimination method.
Multiply Equation 1 by 50 and Equation 2 by 87 to eliminate the 'y' terms:
350x + 4350y = 415750 ----(Equation 3)
7308x + 4350y = 638526 ----(Equation 4)
Now, subtract Equation 3 from Equation 4:
(7308x + 4350y) - (350x + 4350y) = 638526 - 415750
Simplifying the equation:
7308x - 350x = 222776
6958x = 222776
Divide both sides of the equation by 6958:
x = 222776 / 6958
x = 32
Now that we have the value of 'x', we can substitute it back into either Equation 1 or Equation 2 to solve for 'y'. Let's substitute it into Equation 1:
7(32) + 87y = 8315
224 + 87y = 8315
87y = 8315 - 224
87y = 8091
Divide both sides of the equation by 87:
y = 8091 / 87
y ≈ 93
Therefore, the cost of one share in the software company (x) is $32, and the cost of one share in the biotech company (y) is approximately $93.

Answer:
(a) The graph is an exponential growth curve.
(b) f(0) = 2, f(1) = 10
(c) The graph is entirely above the x-axis and increases from left to right, more steeply than the graph of y=5ˣ.
Step-by-step explanation:
Given function:
[tex]k(x)=2(5)^x[/tex]
[tex]\hrulefill[/tex]
Part (a)The graph is an exponential growth curve.
The curve begins in quadrant II, crosses the y-axis at (0, 2) into quadrant I, and increases rapidly as x increases.
In general, an exponential growth function is in the form:
[tex]\boxed{y = ab^x}[/tex]
where:
a is the y-intercept.b is the base.In this case, the y-intercept is 2 and the base is 5.
As the value of a is positive, and the value of b is greater than 1, it indicates exponential growth.
[tex]\hrulefill[/tex]
Part (b)The term "second coordinates" refers to the y-values of the points on a graph.
To find the second coordinates of the points with first coordinates 0 and 1, substitute x = 0 and x = 1 into the function and solve.
[tex]\begin{aligned}k(0)&=2(5)^{0}\\&=2(1)\\&=2\end{aligned}[/tex]
[tex]\begin{aligned}k(1)&=2(5)^{1}\\&=2(5)\\&=10\end{aligned}[/tex]
[tex]\hrulefill[/tex]
Part (c)The graph is entirely above the x-axis and increases from left to right, more steeply than the graph of y=5ˣ.
As 2(5)ˣ > 0, the graph is entirely above the x-axis.
The end behaviour of the function is:
As x → -∞, k(x) → 0.As x → ∞, k(x) → ∞.Therefore, the graph increases from left to right.
In y = 2(5)ˣ, the base is 5, but it is multiplied by 2. This means that for every unit increase in x, the corresponding y-value is doubled compared to the graph of y = 5ˣ. Therefore, the multiplication by 2 makes the graph of y = 2(5)ˣ steeper than the graph of y = 5ˣ.
The graph is completely on the x-axis; It then increases from left to right. it is less steep that y = 5ˣ
The values are (0, 2) and (1, 10)
How to determine the shape of the functionFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2(5ˣ)
The above function is an exponential growth curve
This means that
The graph is completely on the x-axisIt then increases from left to rightit is less steep that y = 5ˣCalculating the values of the functionHere, we have
f(x) = 2(5ˣ)
This gives
f(0) = 2(5⁰)
f(0) = 2
f(1) = 2(5¹)
f(1) = 10
So, the values are (0, 2) and (1, 10)

Answer:
The total amount with annual compounding is 23,304.79 .
The interest with annual compounding is $18,304.79.
The total amount with semi annual compounding is 24,005.10.
The interest with semi annual compounding is $19,005.10.
The total amount with quarterly compounding is 24,377.20.
The interest with quarterly compounding is $19,377.20.
What are the total amount and interest?
The formula for determining the total amount is:
FV = PV(1 + r/m)^nm
Where:
FV =total amount
PV = amount deposited
r = interest rate
n = number of years
m = number of compounding
Interest = FV - amount deposited
FV = 5000 x (1.08)^20 = 23,304.79
Interest = 23,304.79 - 5000 = $18,304.79
FV =5000 x (1.08/2)^(2 x 20) =24,005.10
Interest = 24,005.10 - 5000 = $19,005.10
FV =5000 x (1.08/4)^(20 x 4) =24,377.20
Interest = 24,377.20 - 5000 = $19,377.20

Jalen bought a new iPad. The screen has a perimeter of inches 36 inches and an area of 80 square inches. What are the dimensions of the iPad’s screen?
Let's assume the dimensions of the iPad's screen are represented by length (L) and width (W). We can use the given information to set up two equations.
Perimeter equation:
The perimeter of a rectangle is given by the formula: 2(L + W). In this case, the perimeter is given as 36 inches.
So, 2(L + W) = 36.
Area equation:
The area of a rectangle is given by the formula: L * W. In this case, the area is given as 80 square inches.
So, L * W = 80.
We now have a system of two equations:
2(L + W) = 36
L * W = 80
From equation 1, we can simplify it to L + W = 18 and rewrite it as L = 18 - W.
Now substitute this value of L into equation 2:
(18 - W) * W = 80
Expanding the equation:
18W - W^2 = 80
Rearranging the equation to quadratic form:
W^2 - 18W + 80 = 0
Factoring or using the quadratic formula, we find the two possible values for W.
The solutions are W = 8 and W = 10.
Now we can substitute these values back into the equation L = 18 - W to find the corresponding values of L.
For W = 8:
L = 18 - 8 = 10
For W = 10:
L = 18 - 10 = 8
Therefore, the dimensions of the iPad's screen can be either 8 inches by 10 inches or 10 inches by 8 inches.

a square pyramid has a base with a side length of 3 feet and lateral with a height of 6 feet. what is the area of the pyramid. A.9 square feet B. 27 square feet C. 36 square feet D. 45 square feet
Answer:
D. 45 square feet
Step-by-step explanation:
To find the surface area of a square pyramid, we need to find the area of the base and the area of the four triangular lateral faces.
Finding the area of the baseFirst, let's find the area of the base (square).
[tex]\boxed{\begin{minipage}{7 cm}Base area = side length $\times$ side length\\ \\Base area = 3 $\times$ 3 \\ \\Base area = 9 square feet\end{minipage}}[/tex]
Finding the area of the triangular lateral facesNow, let's find the area of the triangular lateral faces.
Finding the area of one triangular lateral faceAs stated in the problem, the slant height of the triangle is 6 feet. We can find the area of one triangular lateral face:
[tex]\text{Triangle area = $\frac{1}{2}$ $\times$ base $\times$ height}\\\\\text{Triangle area = $\frac{1}{2}$ $\times$ 3 $\times$ 6} \\\\\text{Triangle area = 9 square feet}[/tex]
Finding the total lateral areaSince there are four triangular lateral faces, we need to multiply this area by 4:
[tex]\text{Total lateral area = 4 $\times$ 9}\\\\\text{Total lateral area = 36 square feet}[/tex]
Total surface areaFinally, we add the base area and the total lateral area to find the total surface area of the pyramid:
[tex]\text{Total surface area = base area + total lateral area}\\\\\text{Total surface area = 9 + 36}\\\\\text{Total surfacel area = 45 square feet}[/tex]
ConclusionSo, the area of the square pyramid is 45 square feet. Which is option D.
________________________________________________________
Answer:
D. 45 square feet
Step-by-step explanation:
You want the surface area of a square base pyramid with a side length of 3 feet and a slant height of 6 feet.
Area formulasThe area of a triangular face is given by ...
A = 1/2bh . . . . . base b and height h
The area of the square base is given by ...
A = s²
The total surface area of the pyramid is the area of the base plus the areas of the 4 triangular faces:
total area = s² +4(1/2bh) . . . . where b = s
This can be simplified to ...
total area = s(s +2h) . . . . . area of a square pyramid with slant height h
ApplicationFor the pyramid with a square base 3 ft on a side, and a slant height of 6 ft, the total area is ...
total area = (3 ft)(3 ft + 2·6 ft) = (3 ft)(15 ft) = 45 ft²
The area of the pyramid is 45 square feet.

The value of x in ΔSTU is in the range (2, 32).
Given that ΔSTU is a triangle,
ST = 15,
US = x,
UT = 17.
We need to find the length of x in the triangle STU.
To solve this question, we need to apply the triangle inequality theorem.
According to the theorem, the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Therefore, using this theorem, we get:
ST + US > UT => 15 + x > 17
=> x > 17 - 15
=> x > 2US + UT > ST
=> x + 17 > 15 => x > 15 - 17
=> x > -2UT + ST > US
=> 17 + 15 > x
=> 32 > x
In this case ST = 15, US = x, UT = 17. Let's apply the triangle inequality to the sides of the triangle STU:
ST + US > UT
15 + x > 17
Simplify the inequality:
x > 17 - 15
x > 2
Triangle STU is valid The length of US(x) must be greater than 2 to be a perfect triangle.
However, without further information, we cannot determine the exact value of x.
You can specify any value greater than 2.
Therefore, from the above conditions, we conclude that 2 < x < 32.

A simple random sample of size n is drawn from a normally distributed population, and the mean of the sample is (x with a line over it), while the standard deviation is s. What is the 99% confidence interval for the population mean? Use the table below to help you answer the question.
The 90% confidence interval for the population variance (σ^2) is approximately [7.19, 20.19].
To construct a 90% confidence interval for the population variance (σ^2), given a sample size of 20 and a sample variance (s^2) of 12.5, we need to utilize the chi-square distribution.
The formula for constructing a confidence interval for the population variance is:
[ (n - 1)s^2 / χ^2_upper, (n - 1)s^2 / χ^2_lower ]
Where n is the sample size, s^2 is the sample variance, χ^2_upper is the upper critical value from the chi-square distribution, and χ^2_lower is the lower critical value from the chi-square distribution.
For a 90% confidence interval, we need to find the critical values from the chi-square distribution that correspond to the upper and lower tails of 5% each (since the confidence level is divided equally into two tails).
(a) Degrees of freedom:
The degrees of freedom (df) for the chi-square distribution is equal to n - 1. In this case, n = 20, so df = 20 - 1 = 19.
(b) Chi-square critical values:
We need to find the upper and lower critical values from the chi-square distribution table for df = 19 and a significance level of 0.05/2 = 0.025 (for each tail).
From the chi-square distribution table or using a statistical software, the upper critical value for a significance level of 0.025 and df = 19 is approximately 32.852. Similarly, the lower critical value is also approximately 8.907.
(c) Confidence interval calculation:
Substituting the values into the formula, we can construct the confidence interval:
[ (n - 1)s^2 / χ^2_upper, (n - 1)s^2 / χ^2_lower ]
[ (20 - 1) * 12.5 / 32.852, (20 - 1) * 12.5 / 8.907 ]
[ 19 * 12.5 / 32.852, 19 * 12.5 / 8.907 ]
[ 7.19, 20.19 ]
Therefore, the [7.19, 20.19] is roughly inside the 90% confidence interval for the population variance (2).

Determine the surface area and volume Note: The base is a square.
The volume of the can is approximately 304 cubic centimeters.
To determine the surface area and volume of the can, we need to consider the properties of a cylinder with a square base.
Surface Area:
The surface area of the can consists of three parts: the square base and the two circular faces.
a) Square Base:
The base of the can is a square, so its area is given by the formula:
Area = side^2.
Since the diameter of the can is 8 centimeters, the side of the square base is also 8 centimeters.
Therefore, the area of the square base is 8 cm [tex]\times[/tex] 8 cm = 64 square centimeters.
b) Circular Faces:
The can has two circular faces, one at the top and one at the bottom.
The formula for the area of a circle is[tex]A = \pi \times r^2,[/tex] where r is the radius. The radius of the can is half the diameter, which is 8 cm / 2 = 4 cm.
Thus, the area of each circular face is [tex]\pi \times (4 cm)^2 = 16\pi[/tex] square centimeters.
To find the total surface area, we sum the areas of the square base and the two circular faces:
Total Surface Area = Square Base Area + 2 [tex]\times[/tex] Circular Face Area
[tex]= 64 cm^2 + 2 \times 16\pi cm^2[/tex]
≈ [tex]64 cm^2 + 100.48 cm^2[/tex]
≈[tex]164.48 cm^2[/tex]
Therefore, the surface area of the can is approximately 164.48 square centimeters.
Volume:
The volume of the can is given by the formula:
Volume = base area [tex]\times[/tex] height.
Since the base is a square, the base area is equal to the side^2, which is 8 cm [tex]\times[/tex] 8 cm = 64 square centimeters.
The height of the can is the height we calculated earlier, which is approximately 4.75 centimeters.
Volume = Base Area [tex]\times[/tex] Height
[tex]= 64 cm^2 \times4.75[/tex] cm
≈ 304 [tex]cm^3[/tex]

Charimaya is running a race around a square track of length 75 m. Find the distance covered by her at the end of her fifth round.
At the end of her fifth round, Charimaya would have covered a distance of 1500 meters.
To find the distance covered by Charimaya at the end of her fifth round, we need to calculate the total distance covered in one round and then multiply it by five.
Given that the track is square-shaped with a length of 75 m, we know that all four sides of the track are equal in length.
To calculate the distance covered in one round, we need to find the perimeter of the square track. Since all sides are equal, we can simply multiply the length of one side by 4.
The length of one side of the square track is 75 m. Therefore, the perimeter of the track is:
Perimeter = 4 × 75 m = 300 m
So, Charimaya covers a distance of 300 m in one round.
To find the distance covered at the end of her fifth round, we multiply the distance covered in one round by 5:
Distance covered in 5 rounds = 300 m × 5 = 1500 m
Therefore, at the end of her fifth round, Charimaya would have covered a distance of 1500 meters.
It's worth noting that since the track is square-shaped, each round consists of running along all four sides of the track.

MLMS4 Day 3 (1 hour) SBA Task: Project November 2023 Which sides of the rectangle (that formed the sides of the cylinder) has the same length as the circumference of the circles? Which sides of the rectangle has the same length of the height of the cylinder. What do you notice between your model and the practical calculation.
The sides of the rectangle that have the same length as the circumference of the circles are the sides parallel to the bases of the cylinder. The sides of the rectangle that have the same length as the height of the cylinder are the sides perpendicular to the bases. While the model provides a simplified representation, practical calculations might have slight differences due to real-world factors.
In a cylinder, the two circular bases are connected by a curved surface, forming a three-dimensional shape. The rectangular shape that wraps around the curved surface of the cylinder is called the lateral surface or the lateral area.
To determine which sides of the rectangle have the same length as the circumference of the circles, we need to understand the geometry of a cylinder. The circumference of a circle is calculated using the formula:
Circumference = 2πr,
where r is the radius of the circle. In a cylinder, the bases are identical circles, so the circumference of each base is equal. Therefore, the sides of the rectangle that are parallel to the bases have the same length as the circumference of the circles.
Now, let's consider the height of the cylinder. The height is the distance between the two bases and is perpendicular to the bases. In the rectangular representation of the cylinder, the sides that are perpendicular to the bases represent the height. Hence, the sides of the rectangle that are perpendicular to the bases have the same length as the height of the cylinder.
When comparing the model (rectangular representation) with practical calculations, we may notice some differences. The model provides a simplified representation of the cylinder, assuming that the lateral surface is perfectly wrapped around the curved surface. However, in practical calculations, there might be slight variations due to factors like material thickness, manufacturing processes, or measuring precision. These variations can result in minor deviations between the model and the practical calculations.
It's important to consider that the model is an approximation and serves as a visual aid to understand the basic properties of the cylinder. In real-life applications or engineering calculations, precise measurements and considerations of tolerances are crucial.

f) m∠ADC = 60°
Step-by-step explanation:
Part bThe diagonals of a parallelogram always bisect each other.
Therefore, point E (the point of intersection of the two diagonals) is the midpoint of diagonal AC. So AE = EC.
As EC = 7, then AE = 7.

Part dAs the measure of the opposite angles of a parallelogram are equal, then m∠DCB is equal to m∠DAB. From inspection of the given parallelogram, we can see that m∠DAB = 120°. Therefore:
m∠DCB = 120°
[tex]\hrulefill[/tex]
Part fAdjacent angles of a parallelogram are supplementary (sum to 180°).
Angle DAB and angle ADC are adjacent angles, so their sum is 180°.
Therefore:
⇒ m∠ADC + m∠DAB = 180°
⇒ m∠ADC + 120° = 180°
⇒ m∠ADC + 120° - 120° = 180° - 120°
⇒ m∠ADC = 60°

The height, h, of the cylinder is approximately 1.27 centimeters when the volume is 100 cm^3 and the radius is 5 cm, rounded to the nearest tenth.
To find the height, h, of the cylinder, we can rearrange the formula for the volume of a cylinder:
V = πr^2h
Given that the volume, V, is 100 cm^3 and the radius, r, is 5 cm, we can substitute these values into the formula:
100 = π(5^2)h
Simplifying further:
100 = 25πh
To solve for h, divide both sides of the equation by 25π:
100 / (25π) = h
To calculate the value, we'll use an approximation for π as 3.14:
100 / (25 * 3.14) ≈ h
Simplifying:
100 / 78.5 ≈ h
h ≈ 1.27 cm
Therefore, when the volume is 100 cm3 and the radius is 5 cm, the cylinder's height, h, is about 1.27 centimetres, rounded to the closest tenth.

The perimeter of shape C is 30 cm shorter than the total perimeter of A and B.
What is the perimeter of a polygon?The perimeter of a polygon is given by the sum of all the lengths of the outer edges of the figure, that is, we must find the length of all the edges of the polygon, and then add these lengths to obtain the perimeter.
Hence the perimeter of each shape is given as follows:
A = 2 x (5 + 12) = 34 cm.B = 2 x (4 + 9) = 26 cm.C = 12 + 5 + 9 + 4 = 30 cm.Then the difference is given as follows:
34 + 26 - 30 = 30 cm.

The measure of the Intercepted arc having an inscribed angle of 40 degrees is 80 degrees.
What is the measure of the intercepted arc?An inscribed angle is simply an angle with its vertex on the circle and whose sides are chords.
The relationhip between an an inscribed angle and intercepted arc is expressed as:
Inscribed angle = 1/2 × intercepted arc.
From the figure:
Inscribed angle = 40 degrees
Intercepted arc = ?
Plug the given value into the above formula and solve for the arc:
Inscribed angle = 1/2 × intercepted arc.
40 = 1/2 × intercepted arc
Multiply both sides by 2:
40 × 2 = 2 × 1/2 × intercepted arc
40 × 2 = intercepted arc
Intercepted arc = 80°
Therefoore, the Intercepted arc is 80 degrees.
Option B) 80° is the correct answer.

A water slide is a straight ramp 20 m long that starts from the top of a tower 18 m high. Find the angle the slide forms with the tower. Approximate to the nearest degree.
The angle the slide forms with the tower is approximately 41 degrees (rounded to the nearest degree).
To find the angle the slide forms with the tower, we can use trigonometric ratios. Let's consider the right triangle formed by the height of the tower (18 m), the length of the slide (20 m), and the angle we want to find.
Using the tangent function, we have:
tan(angle) = opposite/adjacent
In this case, the opposite side is the height of the tower (18 m) and the adjacent side is the length of the slide (20 m). Therefore:
tan(angle) = 18/20
To find the angle, we can take the inverse tangent (arctan) of both sides:
angle = arctan(18/20)
Using a calculator, we find that arctan(18/20) is approximately 40.56 degrees.
Therefore, the angle the slide forms with the tower is approximately 41 degrees (rounded to the nearest degree).
