arlik [135]

Answer:

Step-by-step explanation:

The scale factor multiplies each coordinate value. If the scale factor is k, then we have ...

D' = kD

(36, -12) = k(12, -4) = (12k, -4k)

k = 36/12 = -12/-4 = 3

The scale factor of the dilation is 3.

Reptile [31]

Answer:

She returned 5 gifts.

Step-by-step explanation:

36 gifts is 60% = 0.6 of all the gifts that she received. How many presents are 100% = 1?

36 gifts - 0.6

x gifts - 1

0.6x = 36

x = 36/0.6

x = 60

She received 60 gifts.

She opened the rest of the gifts and found that 25% of them were the same present

The rest is 60 - 36 = 24 gifts.

25% is (1/4)*24 = 6 duplicate figts

She returned all but one of the duplicate gifts.

That is, she returned 6 - 1 = 5 gifts.
