The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
4 A) 1/6
4 B) 1/45
4 C) 2/3
4 D) 3/5
Answer: The answer is B. 0.208.
Step-by-step explanation: Just took the test on e2020
24% of 80 is 19.2
120% of 70 is 84
20% of 150 is 30
0.8% of 150 is 1.2
120% of 85 is 102
Question 1: You just do 400 x 14, and the answer is 5,600.
Question 2: You divide 7,600 by 400, and the answer is 19.
