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

$Volume=125 \times 75$

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

What is the x-intercept of the line with this equation 8x - 1/3y = 15?

Flura [38]

Isolate the x. Note the equal sign. What you do to one side, you do to the other. First, add 1/3y to both sides

8x - 1/3y (+1/3y) = 15 (+1/3y)

8x = 15 + 1/3y

Divide 8 from both sides

(8x)/8 = (15 + 1/3y)/8

x = 15/8 + 1/24y

x = 1/24y + 1.875

x = 1/24y + 1.875 is your answer

hope this helps
