A summary of the question is High School A rented and filled 1 van and 6 buses with 372 students .. High school B rented 4 Vans and 12 buses with 780 students..
each van and each bus carried the same number of students. how many students can a van carry , and how many students can a bus carry.
I need this to be broken down to me as much as possible because I. not really good with math .. at all ..

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
