A waterwheel is being turned by a stream at a rate of 3 revolutions per minute. If the diameter of the wheel is 15 ft, then how fast is the stream flowing

0.7176 m/s m/s

Step-by-step explanation:

We are given;

Rate = 3 rev/min

Diameter: d = 15 ft

Now, we want to find how fast the stream is flowing which is the linear velocity.

Thus;

linear velocity = circumferential distance × number of revolutions

Now, circumferential distance = πd

Circumferential distance = 15π

Thus;

linear velocity = 15 × π × 3 = 45π ft/min

Converting to m/s gives;

Linear velocity = 45π/197 m/s

Linear velocity = 0.7176 m/s

3rd box is the answer

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
