See below
Step-by-step explanation:

Hence, both ratios are equal to each other
70 times .9 is 63 so 90 minus 63 is27 so it was $27
The answer to that question would be 410 miles per hour
hookes law gives the equation F=kx where F is the elastic force and k is the constant and x or small e is extension if we draw a graph you'll see that the graph increases by the same ratio every single time hence giving a straight line show that they are F and x are propotional to a certain limit
Answer:
don't write sloppy and I'll be able to answer it
