When Ramon looked out at the school parking lot, he noticed that for every 3 minivans, there were 7 other types of vehicles. If there are a total of 150 vehicles in the parking lot, how many of them are minivans?

Step-by-step explanation:

If there were 3 vans for every 7 cars, then there were 3 vans for every 10 of the total in the lot. Use a proportion to solve this:

and cross multiply to get

10x = 450

so x = 45

There are 45 vans in the lot.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
