Answer:
C
Step-by-step explanation:
the answer is 15. hope this helps
employed: 1,312,700 people
- employed : 100% - 5.6% = 94.4%
employed people:
The distance is 20 speed 58 =h
20×58 in 1 hour =1160
Ratios
Note A has a frequency of
fa=1,760 Hz
Note D has a period of 1,175 hertz
(the previous data should be frequency, not period)
We are required to find the ratio of A to D. Let's call it r:

Dividing: r = 1.4978. Rounding to two decimal places:
r = 1.50
Now to express the answer in integer ratio form, we need to simplify the fraction.
First, we divide by 5 up and down:

There are no more common divisors for both numbers, thus the integer ratio form is r = 352/235
