Answer:
8 hours
Step-by-step explanation:
Step one:
Given data
Tom earned $72 walking dogs for 6 hours
amount earned = $72
time taken = 6 hours
Required
The time taken to earn $96
Step two:
let us find the unit rate of his earning
unit rate = 72/6
= 12 per hour
In 1 hour Tom earns $12
in x hours he will earn $96
cross multiply we have
96*1= 12x
divide both sides by 12
x= 96/12
x=8 hours

Answer:
h = 9/16 or 0.5625
Step-by-step explanation:
volume of cone = pi (r^2) (h)
225pi = pi * r^2 * h
Divide pi from both sides.
225 = 20^2 * h
225 = 400h
Divide by 400.
9/16 = h
You just add all of the weight of the contents together. 12 3/4+ 8 1/4 +7, which equals 28 pounds.
