Answer:
$14.98
Step-by-step explanation:
55.25. You multiply 0.40 by 85 and you’ll get 34, subtract 85 by 34 and you’ll get 51. Then you multiply 0.05 by 85 and get 4.25. Add 4.25 by 51 and you’ll get 55.25.

Hope this helps!
(P.S.I changed the answer)
When the decrease in velocity (the acceleration) is uniform, the average velocity is [Initial velocity - Final velocity]/2
We know tha the initial velocity is 0.96 rev / sec and the final velocity is 0,
Then, the average velocity is [0.96 / 2 ]rev /sec = 0.48 rev/sec.
Also, by defintion,
average velocity = number of rev / time,
From which, number of rev = average velocity * time
So, number of rev = 0.48 rev/sec * 2.4 min * 60sec /min = 69.12 rev
Answer: 69.12 revolutions
Step-by-step explanation:
The rectangle area is equal to LENGTH * WIDTH
then
t^2-16t+48 = L*W
L = [t^2-16t+48] / W
and
t^2-16t+48 = L*W
W = [t^2-16t+48] / L
