Find 1% of $350:
$350*1/100 = $3.5Find 8% of $350:
$3.5*8 = $28Here are the steps
First find 1% of 350Then multiply with 8/1=8 times with 1%Lets do
[tex]\\ \tt\longmapsto 0.01(350)=3.50[/tex]
Multiply with 8
[tex]\\ \tt\longmapsto 8(3.50)=24.00+4.00=28.00\$[/tex]

If the diameter of a circle is 20 inches, what is the radius?
Answer:
Step-by-step explanation:
Diameter = 20cm . Radius = 10 cm. Circumference = 2πr = 2(3.14)(10) = 6.28 * 10 = 62.8 cm.
Answer:
radius=10
Step-by-step explanation:
radius is always half the diameter therefore the answer is 10 inches.
In terms of x, what is the length of the side of a square whose area is represented by the expression 25x^2 + 40x + 16?
Answer:
Step-by-step explanation:
25x2 − 40x + 16 = (5x)² - 2*5*4 + 4² { (a - b)² = a² - 2ab + b² }
= (5x - 4)² { here a = 50 and b = 4}
Side of the square = 5x - 4 units
Part B:
25x2 − 16y2 = (5x)² - (4y)² { a² - b² = (a + b) * (a - b) }
= (5x + 4y) * (5x - 4y) { here a = 5x and b = 4y}
Dimensions of Rectangle: (5x + 4y) ; (5x - 4y)
Answer:
Step-by-step explanation:
25x²+40x+16=25x²+20x+20x+16
=5x(5x+4)+4(5x+4)
=(5x+4)(5x+4)
=(5x+4)²
length of side=5x+4
Find the area of the region that lies under the parabola y=5x - x^2, where 1≤x≤4. I would definitely like to see some work :)
Answer:
16.5 square units
Step-by-step explanation:
You are expected to integrate the function between x=1 and x=4:
[tex]\displaystyle\text{area}=\int_1^4{(5x-x^2)}\,dx=\left.\left(\dfrac{5}{2}x^2-\dfrac{1}{3}x^3\right)\right|_{x=1}^{x=4}\\\\=\dfrac{5(4^2-1^2)}{2}-\dfrac{4^3-1^3}{3}=37.5-21=\boxed{16.5}[/tex]

Additional comment
If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.
The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.
This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...
area = 4.5 +3×4 = 16.5 . . . square units

Which ratio is larger, 18/5 or 72/25 ?
Answer:
Step-by-step explanation:
LCM of 5 and 25=25
Now,
18/5=18x5/5x5=90/25
72/25=72/25
Since 90/25>72/25
Hence,
18/5 is greater than 72/75

Find the area of the shaded region. Use 3.14 as an approximation.
Answer:
shaded area = 113.64 cm²
Step-by-step explanation:
To find the shaded area, subtract the area of the circle from the area of the triangle.
Area of a triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²
Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)
From inspection, we can see that the diameter of the circle = 14 cm
Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm
⇒ area of circle = 3.14 x 7² = 153.86 cm²
Shaded area = area of triangle - area of circle
⇒ shaded area = 267.5 - 153.86 = 113.64 cm²

If the expression is expanded, what is the coefficient of x?
4 (3x + 5)
Coefficient of x =
Answer:
12
Step-by-step explanation:
Start by expanding the expression:
4(3x+5)
Distribute the 4 to each of the numbers in the parentheses
12x+20
The coefficient of x is basically what is being multiplied by x. In this scenario, we can expand 12x to be...
12*x
Which means that the coefficient of x is 12
12x+20
12x+20=0
12x=-20.
12÷12x=-20÷12

A jar is full of 100 coins. All of the coins are either nickels or dimes.
a. The value of the coins is $6.35. Write a linear system representing this equation.
b. Solve the system to determine how many of each type of coin is in the jar.
Answer:
73 nickels, 27 dimes
Step-by-step explanation:
x+y=100
5x+10y=635
x=100-y
5(100-y)+10y=635
500-5y+10y=635
500+5y=635
5y=135
y=27
5x+10(27)=635
5x+270=635
5x=365

Fill in the missing number.
70% of _____=42
Answer:
60
Step-by-step explanation:
70% of x = 42
.7x = 42
x = 42 ÷ .7
x = 60
Answer:
60
Step-by-step explanation:
We have, 70% × x = 42
or,
[tex]\frac{70}{100}[/tex] × x = 42
Multiplying both sides by 100 and dividing both sides by 70,
we have x = 42 × [tex]\frac{100}{70}[/tex]
x = 60
If you are using a calculator, simply enter 42×100÷70, which will give you the answer of 60
The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 148 inches?
Answer:
The possible values of S are the values between 37 and 49. (Excluding 37 and 49)
Step-by-step explanation:
If the perimeter of the square must be greater than 148 inches but less than 196 inches.
And perimeter of a square = 4s
We intend to find the values of s such that:
148 < 4s
¹⁴⁸⁄₄ < ⁴ˢ/₄
37 < s
Also:
4s < 196
s < ¹⁹⁶⁄₄
s < 49
Therefore:
37 < s < 49.
The possible values of s are the values between 37 and 49. (Excluding 37 and 49.)

John's bicycle covers 60 inches in one revolution. What
is the radius of his tire?
Answer:
The radius is equal to [tex]\frac{30}{pi}[/tex] or about 9.5 inches
Step-by-step explanation:
A revolution is the same as the circumference,
which can be found using C = 2πr
C = 2πr
60 = 2πr
(2π)r = 60
r = [tex]\frac{60}{2pi}[/tex]
r = [tex]\frac{30}{pi}[/tex] or about 9.5 inches

A television network is tracking the viewing numbers for the beginning episodes of a new show. The second episode had 80% of the viewers from the first episode. and the third episode had a 20% increase in viewers from the second episode.
The number of viewers in the third episode was 2.16 times that of the second episode.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of viewers in the first episode.
The second episode = x + 80% of x = x + 0.8x = 1.8x
For the third episode = 1.8x + 20% of 1.8x = 1.8x + 0.36x = 2.16x
