A person in good physical condition can put out 95 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time: How many people would it take to run a 4.64–kW electric clothes dryer? (You do not need to enter any units.)

The number of people to power a 4.64 kW electric dryer at 95 W per person is ≈ 49 people

Step-by-step explanation:

Here we have power out[put per person = 95 W

Therefore the total power required to run a electric clothes dryer = 4.64 kW

Therefore, the number of people required to perform run a 4.64 kW electric clothes dryer is given by

Number of people required = Power input required ÷ Power output per person

≈ 49 people.

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
