Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.

The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56
Answer = 15 pi or about 37.12
Explanation: First you find the circumference using the formula c=2(pi)r. Radius = 18
C=2pi(18). Circumference= 36pi
Next find the measure of the arc. Multiply (36pi) by (150*degree of the arc*/360*total degree of a circle*). Plug into calculator.
1 kilogram (kg) is 1000 grams. So 3,560 grams is
