Answer:
57
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
For a pile with a radius of 8.5 m and a height of 9 m, the volume is ...
V = (1/3)π(8.5 m)²(9 m) = 216.75π m³ ≈ 680.94 m³
Then the number of truckloads required to create that size pile will be ...
(680.94 m³)/(12 m³/truck) = 56.745 trucks
Even a partial truck load entails another trip, so ...
57 truck loads of sand are needed.
Chang 3/5 to 6/10 than add 6/10+9/10 the top numbers together and that would be 15/10. than / by 5 witch = 3/2
-8, just set x = 0 and find y
Add each angle for the question and make them equal 180
Example: number 15
(23x-5)+(21x+5)=180
