Amerry go round revolves 2 times per minute, jack is 10 feet from the center while bob is 14 feet from the center

Jack's linear speed is 126ft/min

Bob's linear speed is 176ft/min

Step-by-step explanation:

First of all, find the circumference of both circles given the radius; Jack, 2pir (10)=63ft. Bob 2pir(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
