So to find how many tenths, or 1/10's, there are in four fifths, or 4/5, divide 4/5 by 1/10.
Now, remember that <u>dividing by a number is equivalent to multiplying by its reciprocal</u>. To find the reciprocal, just flip the numerator and denominator around. In this case, 1/10 would become 10/1. Flip 1/10 to its reciprocal, change the sign to multiplication, and multiply numerators with numerators and denominators with denominators:
<u>In short, there are 8 tenths in four fifths.</u>

Answer:
This question is impossible! For two different variables, we need two different equations. Without that, there is no hope! :)
Answer:
The average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -80 feet per second.
Step-by-step explanation:
The function that models the height of the ball is:
At t=3, 
At t=5, 
The average rate of change is simply the slope of the secant line connecting.
and 
.
