T ∫ 1/√(1 - x²) dx = arcsin(x)
<span> ∫ 1/√(1 - x²/a) dx = √a arcsin(x/√a) </span>
<span>So pull a factor of 5 out of the square root to get </span>
<span>1/5 ∫ 1/√(1 - 16 x²/25) dx </span>
<span>= 1/4 arcsin(4 x/5)</span>
You could set up a proportion
86/x = 98/100
Then solve for x, I'll do it by cross-multiplying.
86 times 100 divided by 98 = 87.755102
87-88 problems
everyone will get 2 burgers i got this answer by multiplying 8 and 6 and then i divided it by 24 and i got 2
hope it helps
