- the circle graph better shows proportion of each responses to total responses in percentage form.
The answer is "D".
x+x+(x+11)+(x+11)=86
4x+22=86
subtract 22
4x=64
divide by 4
x=16
Answer:
The answer is 4.
Step-by-step explanation:
Since the fractions have the same denominators, all you have to do is subtract 1/5 from 1/5. When you subtract the numerators (1-1) you get 0. That would make the fraction 0/5, but that does not have to be included in the answer since it has no value. Subtract the whole numbers (23-19) to get 4.

Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
