We have been given 4 choices. We are asked to choose the volume that could belong to a cube with a side length that is an integer.

We know that volume of a cube is cube of each side length.

To solve our given problem, we will take cube root of each given value. The cube root of which value will be an integer that will be our correct choice.

A. s^3=18

\sqrt[3]{s^3}=\sqrt[3]{18}

s=2.62074

Since cube root of 18 is not an integer, therefore, 18 is not a correct choice.

B. s^3=36

\sqrt[3]{s^3}=\sqrt[3]{36}

s=3.301927

Since cube root of 36 is not an integer, therefore, 36 is not a correct choice.

C. s^3=64

\sqrt[3]{s^3}=\sqrt[3]{64}

s=4

Since cube root of 64 is 4 and 4 is an integer, therefore, 64 is the correct choice.

D. s^3=100

\sqrt[3]{s^3}=\sqrt[3]{100}

s=4.641588

Since cube root of 100 is not an integer, therefore, 100 is not a correct choice.

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 oz of red tone, 3/4 oz of gray
nadezda [96]

Answer:

We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:

1 1/8x + 3/4x + 5/8x = 20

2 1/2x = 20

x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.
