The radius of each wheel of a car is... Please answer quickly

16.1 MPH

Step-by-step explanation:

If the wheels have a radius of 15 inches, then the circumference of a wheel is 2πr = 2 * π * 15 ≈  94.248 inches.

If the wheels turn at 3 revolutions per second, that mean the car is travelling 94.248 * 3 ≈ 282.74 inches/second.

There are 12*5280 = 63360 inches in a mile and 60 * 60 = 3600 seconds in an hour. So to convert from inches/second to miles per hour, we need to divide the inches per second figure by (63360/3600), which is 17.6, to get miles per hour (MPH).

So in this case, 282.74/17.6 gives you approximately 16.1 MPH.

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
