Answer:
Step-by-step explanation:
A = 7x, c = 4x, s = 3x
a = s+52
7x = 3x+52
4x = 52
x = 13
c = 4x = 52
Caroline gets 52.
This is just a porportion. So if 250 meters is 1 meter than: 250/1
And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x
Set them equal to each other 250/1=212/x
Cross multiply: 212=250x
Divide to find x: 212/250=x
x=212/250
x=0.848
So the height of the model, to the nearest 10th would be 0.8 meters.
