I believe it is 128. I may be wrong but if there are 384 tickets sold and there were 2 times more student tickets sold than adult then there are 128 tickets lift over to be adult tickets
<span>∫(sinx cosx)^2dx = ∫(1/2sin 2x)^2 dx = 1/4∫sin^2 2x dx = 1/4∫1/2(1 - cos 4x)dx = 1/8∫(1 - cos 4x) dx = 1/8[x - sin 4x / 4] + c = 1/32(4x - sin 4x) + c

the right answer is actually 30,60,90, I got the answer right on the test
20/8 = 10/4 = 5/2
So, it's mixed form would be 2 1/2
If you calculate 240/48, you will get 5 without any remainder, which means if you get 5 buses it can exactly take all students?
