A flywheel rotates 450 times in 1 minute. How many degrees does it turn in 1 second?
a. 39 degrees
b. 2700 degrees
c. 18 degrees
450 times in 60 sec
450 times of 360 deg in 60 sec
162000 deg in 60 sec
162000/60 in 1 sec
2700 deg in 1 sec
choose B 

The speed of a carousel is 4.3 revolutions per minute. James chooses a red horse. If the typical ride is 5 minutes, how far is his starting point is James when the ride is over?
a. 90 degrees
b. 0 degrees
c. 180 degrees
4.3 revolutions per 1 minute
4.3 x 5 revolutions in 5 min 
21.5 revolutions in 5 min
Means: a 21 whole revolution and a half of a revolution. A half of a circle  = 180 degrees.
choose C

Step-by-step explanation:

We have been given a sum . We are asked to rewrite this sum using distributive property and greatest common factor.

First of all, we will find greatest common factor of 72 and 60.

Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

We can see that the greatest common factor of 72 and 60 is 12.

We can rewrite our given sum as:

Upon factoring out 12, we will get:

Therefore, our required expression is .
