It takes the dryer 45 inutes to dry a load of towels. if the dryer uses 6,750,000 joules of energy to dry the towels, what is the power rating of the machine?

Given:
45 minutes
6,750,000 joules

Power(w) = Work(j) / Time(s)

Convert the time from minutes to seconds
1 minute = 60 seconds

45 minutes * 60 seconds/min = 45 * 60 seconds = 2,700 seconds

w = 6,750,000 joules / 2,700 seconds
w = 2,500 watts

The power rating of the dryer is 2,500 watts.

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
