The total distance a ball rolls vanes directly with the time in seconds. The ball rolls a total distance of 132 centimeters in 11 seconds What is the time in seconds the ball rolls when the total distance is 108 centimeters?
I need help

the awnser is 9 seconds

Step-by-step explanation:

132÷11=12

12 cm per second

so 108÷12=9

9 seconds

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
