The formula for the area of a trapezoid is:
A= (a+b)/2*h
A=150
h=10
b=14
a=?
So we need to solve for a. Let's plug in the values that we do know...
A= (a+b)/2*h
150=(a+14)/2*10
150=(a/2+14/2)*10
150=(a/2+7)*10
Divide both sides by 10
15=a/2+7
subtract 7 from both sides
8=a/2
multiply both sides by 2
16=a
The other base is 16

Answer:
i wish i could help. im so bad at math
Step-by-step explanation: good luck
1. 20 of 40 is 50% 20/40 = 1/2 1/2 = 50%
2. It is 20% because 600 is 20% of 3000
3. 40% of 30 = 12 50 = 15 10% = 3 (get it)
4, 40% of 65 = 26 50%= 32.5 (get it)
