In the city of Springfield. 75% of

Vlad1618 [11]

Answer: 20 parks

Step-by-step explanation:

Let the total number of parks be y.

Then 75% of y = 15 , that is

$\frac{75}{100}$ x y = 15

75y = 15 x 100

75y = 1500

divide through by 75

y = 1500/15

y = 20

Therefore Springfield have 20 parks altogether

A cylinder has a radius of 5 feet and a height of 8 feet. Which of the following can be used to calculate the volume of a cone t

Lilit [14]

The answer is 1 over 3(3.14)(5²)(8)

The volume of the cylinder (V1) is:
V1 = π · r² · h (r - radius, h - height)

The volume of the cone (V2) is:
V2 = 1/3 π · r² · h (r - radius, h - height)

It is given:
r = 5 feet
h = 8 feet
π = 3.14

Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8 which is the same as 1 over 3(3.14)(5²)(8).

Answer: Choice A

Raising something to the 1/4th power is the same as applying the 4th root to that expression. Raising an expression to the 1/n power is the same as applying the nth root.

Rule:
$x^{1/n} = \sqrt[n]{x}$
(if the text is too small it basically says x to the (1/n) = square root with a small 'n' all over x)
