Determine whether the dilation from Figure ABC to Figure A'B'C' is a reduction or enlargement Then find its scale factor.

This dilation from Figure ABC to Figure A'B'C' is a reduction, with a scale factor of 1/3.

Step-by-step explanation:

The points for Figure ABC are

A =(3,3)

B =(6,3)

C =(6,-3)

The points of Figure A'B'C' are

A' =(1,1)

B' =(2,1)

C' =(2,-1)

To get from (3,3) to (1,1) we have to multiply by 1/3, (6,3) to (2,1) multiply by 1/3, and so on.

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.
