Ryan estimates the measurements of the volume of a container to be 36 cubic inches. the original volume of the popcorn container is 40 cubic inches.

Part A: find the difference

Part B: Find the percent of change

Step-by-step explanation:

The difference between the new volume and the original volume is ...

  (new volume) - (original volume) = (36 in³) - (40 in³) = -4 in²

__

The percentage change is figured with respect to the original volume:

  % change = (difference)/(original volume) × 100% = (-4 in³)/(40 in³) × 100%

  = -1/10 × 100% = -10%

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
