Answer = 4 ft
Radius = Circumference / (pi x 2)
Radius = 8 / (4 x 2)
Radius = 4
Step-by-step explanation:
7ft = 84in 84 ÷ 15 = 5.6 pieces he can cut from each board. Since .6 is not a whole piece measuring 15 inches long, he can only cut 5 pieces from each board.
So, 5 x 2 = 10
He would be able to cut 10 pieces measuring 15 inches long.
Hope this helps :)
So we have two quantities and need to find out how much percentage it increased from one to another and then maybe write an equation that describes the behavior. Lets find the percentage raise between quantities using a simple rule of three, direct proportion:
<span>150 -----> 100</span>
162 ----> x
x = (162)(100)/150
x = 108
that means that $162 is the 108% of $150, or that the tickets are raising their price by 8% daily. The problem states as well that the price grow is exponential, not expressed by a linear equation that is.
