the answer is complimentary
X= total number of problems
This is a proportion problem. 80% is to 100% as 32 problems is to x problems.
80/100=32/x
Cross multiply
(80*x)=(100*32)
80x=3200
Divide both sides by 80
x=40
There were 40 questions on the test.
Hope this helps! :)
Answer:
To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor

Answer
e^c = 3
Step by step explanation
The general exponential equation is y = a^x, where "a" is the base and "x" is the exponent.
We are given c = ln 3
Here the base is "e"
e^c = e^ln 3
e^c = 3 [base "e" and "ln" get cancelled because they are inverse]
Therefore, the answer is e^c = 3
Hope you will understand the concept.
Thank you.
