Set up the following word problem as a proportion and solve. Show all of your work.

scoray [572]

The proportion would be -

12 / 150 = x / 225.

That is, 12 per 150, x amount per 225

To solve this proportion, you can cross multiply (multiply the values diagonally) -

12 / 150 = x /225
150x = 12(225)
150x = 2700
x = 18

18 vials are required to treat 225 people.

Hope this helps! (:

A cube with a volume of 75 cm³ is dilated by a factor of 5.

Brrunno [24]

ANSWER

The volume of the dilated cube is 9375cm³.

EXPLANATION

The volume of the original cube is 75 cm³.

The scale factor for the dilation is 5.

The scale factor for volume is 5³=125

We multiply the volume of the original cube by 125 to obtain the volume of the dilated cube.

The volume of the dilated cube is

$Volume=125 \times 75$

$Volume=9375 \: {cm}^{3}$
