Y2-y1 divides by x2-x1 = 4/9
Answer:
8 students in each van ~ 22 in each bus
Step-by-step explanation:
- Equations:
8v + 8b = 240
4v + b = 54
------
- Modify:
8v + 8b = 240
8v + 2b = 108
------
- Subtract and solve for "b":
6b = 132
b = 22 (# of students in each bus)
-----
- Solve for "v":
4v + b = 54
4v + 22 = 54
4v = 32
v = 8 (# of students in each van)
I found 50, making a rule of three where
40__10
x___25
x=10
40+10= 50
( I hope I'm right, but from what I understand this would be the resolution)
I believe the formula to find the height would be h= 2a/b and if you use that formula and plug in the area (21.7) of each triangle as well as the base (6) then you would get a height of 7.2 cm. I hope this is correct! :)
