Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The area of a trapezoid is equal to
![A=\frac{1}{2}[b_1+b_2]h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Bb_1%2Bb_2%5Dh)
where
b_1 and b_2 are the length of the parallel bases
h is the height (perpendicular distance between the parallel bases)
we have
substitute
![A=\frac{1}{2}[210+480]320=110,400\ mi^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B210%2B480%5D320%3D110%2C400%5C%20mi%5E2)

Hello!
First you find out the amount of balloons by adding them up
10 + 12 + 15 + 8 = 45
Then you add all the balloons that are not green
10 + 12 + 15 = 37
Then you put the amount of balloons that are not green over the total amount of balloons
The answer is 37/45
Hope this helps!
