Answer:

A. 1,485 cubic cm. B. 27

Step-by-step explanation:

The new prism is dilated by a factor of 3, that means it's made bigger, 3 times bigger on each side.

The dimensions of the new prism are then 12 cm by 7.5 cm by 16.5 cm.

Its volume is then of 12 x 7.5 x 16.5 = 1,485 cubic cm

To answer the second question...

Let's calculate the volume of the original prism:

The original prism's volume was 4 x 2.5 x 5.5 = 55 cubic cm

The new volume is then 1485 / 55 = 27 times bigger than the original.

Which is normal, since we increased each side (dimension) by a factor of 3, so 3x3x3 = 27.

Explain how to find coordinates for Q

Vesna [10]

Answer:

Q = (4, - 1)

Step-by-step explanation:

DF is the diameter of the circle with center Q.

So, Q is the midpoint of DF.

By mid point formula.

$Q = \bigg( \frac{1 + 7}{2}, \: \: \frac{3 - 5}{2} \bigg) \\ \\ Q = \bigg( \frac{8}{2}, \: \: \frac{ - 2}{2} \bigg) \\ \\ Q = (4, \: \: - 1)$

What is the measure of DE? 16 12 20 10

AnnyKZ [126]

set up a ratio to find the length:

15/12 = DE/16

cross multiply the 15 & 16:
15 * 16 = 240

divide that by 12 to get DE

240 / 12 = 20

DE = 20
