3 times: Rate, Rate of change and Slope.
You do 20 teachers multiplied by 7 departments because there are 20 teachers 7 times.
Multiplying them gets you 140.

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

Divide the number of candy bars (34), by the number each box can hold (5)

Since we cannot have 6.8 boxes, we have to round down to 6.


To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!
If given the circumference you can solve for the radius which will be the height of the parallelogram. also with the circumference you can divide by 2 to find the base of the parallelogram. so all you have to do now is times the radius by half the circumference to find the area
