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.

true? is that what you're asking or do you mean something else?

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
