I need help just on #6 please!

Answer:

1:1

Step-by-step explanation:

Since the surface area of A is 4 times the surface area of B, and the volume of B is 125 times the volume of C, we can write the following proportion:

(surface area of A) / (surface area of B) = (volume of B) / (volume of C)

(height of A)^2 / (height of B)^2 = (height of B)^3 / (height of C)^3

We can then cross-multiply and simplify to find the ratio of the heights:

(height of A)^2 / (height of C)^2 = (height of B)^3 / (height of B)^3

(height of A)^2 = (height of C)^2

Therefore, the ratio of the height of A to the height of C is 1:1, or simply 1.

Answer: 25 weeks

Step-by-step explanation:

Let W represent the number of weeks

Judy equation is

12W + 300

Cassie equation is

20W + 100

Now let's solve it! Our system of equation is

12W + 300 = 20W + 100

Subtract 300 from both sides

12W = 20W -200

Subtract 20W from both sides

-8W = -200

W = 25 weeks

So, it takes 25 weeks for Judy and Cassie to have the same amount saved.

Answer:

let judy = 300 + 12W

cassie = 100 + 20W

300 + 12W =  100 + 20W

300 - 100 = 20W - 12W

200 = 8W

W = 25

300 +  12(25) = 100 + 20(25)

300 + 300 = 100 + 500

600 = 600

Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

What does distribution mean in work?

Distribution is the activity of both selling and delivering products and services from manufacturer to customer. This can also be called product distribution. As businesses become more global it becomes important to improve distribution to ensure that customers and all members of the distribution channel are happy.

To obtain the marginal distribution of gender :

Total number of civilians (male + female)

(26393 + 27330) = 53,723

Male :

P(male) = number of male / total

P(male) = 26393 / 53,723 = 0.4912793

P(Female) = number of Female / total

P(Female) = 27330 / 53,723 = 0.5087206

The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

x = (-5 ± √(5² - 4(1)(6)))/2(1)

14 - 4[tex]\sqrt{6}[/tex] = ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])

14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) - (-4y)

14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) + 4y  ==> subtracting by a negative number is

                                               equivalent to adding by a positive number

14 - 4[tex]\sqrt{6}[/tex] = x + 4y - 4[tex]\sqrt{xy}[/tex]   ==> notice any similarities?

x + 4y = 14

[tex]\sqrt{xy}[/tex] =  [tex]\sqrt{6}[/tex]

xy=6  ==> solve for x

x = 6/y  ==> isolate x by dividing by y on both sides

6/y + 4y = 14  ==> plugin 6/y for x in x + 4y = 14

(6/y + 4y = 14) * y  ==> multiply the equation by y to remove fractions

6 + 4y^2 = 14y

4y^2 - 14y + 6 = 14y-14y

4y^2 - 14y + 6 = 0

2y^2 - 7y + 3 = 0  ==> divide both sides by 2 to simplify the equation

2y^2 - 1y - 6y + 3 = 0  ==> -1y - 6y = -7y

y(2y - 1) - 3(2y - 1) = 0  ==> factor the equation

(y - 3)(2y - 1) = 0

y - 3 = 0 ==> y=3

2y - 1 = 0 ==> 2y = 1  ==> y = 1/2

y=3: 3x = 6 ==> plugin 3 for y in xy = 6

x = 2 ==> divide both sides by 3

y=1/2: x/2 = 6 ==> plugin 1/2 for y in xy = 6

x = 12  ==> multiply both sides by 2

When y=3, x=2.  When y=1/2, x=12

Hence, the answers are (2, 3) and (12, 1/2).

Step-by-step explanation:

first of all, remember for life :

the sum of all angles in a triangle is always 180°.

so, in this right-angled triangle we have therefore

180 = b + 90 + 71

b = 180 - 90 - 71 = 19°

and then regarding a and b :

the sum of all angles around a single point on one side of a line is also always 180°.

why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.

so,

a + b = 180

a + 19 = 180

a = 180 - 19 = 161°

FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.

So in the fraction 3/8 the numerator is 3. In the fraction 1/9 the numerator is 1.

The dot plots show that the lowland areas experienced significantly more rainfall than the highland area during spring storms, with a larger range and maximum rainfall.

The dot plots show the rainfall totals for several spring storms in both highland and lowland areas. The dots representing the lowland areas are more spread out and have a larger range compared to the dots representing the highland areas. This indicates that the lowland areas experienced more rainfall than the highland areas during these storms. Additionally, the maximum rainfall for the lowland areas is greater than the maximum rainfall for the highland areas, further emphasizing the difference in rainfall between the two areas. This could be due to a number of factors, such as the higher elevation of the highland areas resulting in less moisture being able to accumulate, or the lower temperature of the highland areas resulting in less evaporation and thus less rainfall. Additionally, the lower elevation of the lowland areas could result in more moisture being able to accumulate, and the higher temperature of the lowland areas could result in more evaporation, leading to increased rainfall. Regardless of the cause, the data from the dot plots clearly show that the lowland areas experienced more rainfall than the highland areas during these spring storms.

The number of student tickets sold is 40 and the number of adult tickets sold is 60.

Define System of equations

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given,

Each student ticket sells for = $4

Each adult ticket sells for = $8

Total tickets sale = 100

Revenue from the sale of 100 tickets = $640

Let, x = number of student tickets sold

and, y = number of adult tickets sold

so, let's form a equation

x + y = 100             ------(i)

4x + 8y = 640        -------(ii)

Rewrite eq(i),

x = 100 - y

Now, substitute x value in eq(ii)

4(100- y) + 8y = 640

400 - 4y + 8y = 640

4y = 640 - 400

y = 240 / 4

y = 60

Now, put y value in eq(i)

x + 60 = 100

x = 40

Hence, the number of student tickets sold is 40 and the number of adult tickets sold is 60.

Now, to solve graphically

Let's rewrite the eq(i) and eq(ii)

y = 100 - x

y = 80 - (1/2) x

In statistics, the p-value is used to determine the likelihood that the observed relationship between two variables occurred by chance. If the p-value is small, it means that the relationship is statistically significant and unlikely to have occurred by chance.
