it 20 chews 5 over 20 chews 10

= 20! / (20-5)! times 5!  over 20! / (20-10)! times 10!

=15504/ 184756= .08 or 8%

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
