What is the volume of a sphere with a radius of 30 m? 1,200π m3 288,000π m3 36,000π m3 20,250π m3

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

it would be 3 ÷by 6 because the number on each side

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
