Answer:

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.

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

How many solutions does the nonlinear system of equations graphed below have?
NeTakaya

Answer:

Three solutions.

Step-by-step explanation:

In order to solve system of equations by graphical method, we graph the system of equations. The intersection point (s) of the two graph would give us the solution.

If the graph of the equations intersect at 2 points then there will be 2 solutions, if there are 4 intersection then there would be 4 solutions and so on.

For the given graph, we  can see that there are three intersection points.

Hence, there would be three solutions.
