Answer:
<em>5 more man should be added</em>
Step-by-step explanation:
<u>Inverse Proportion</u>
The time needed to complete a job is inversely proportional to the number of men working on it.
It means the more men working, the less time needed to complete the job.
We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:
25 men are needed which means 25-20 = 5 more men should be added.
5 more man should be added
There are 5280 feet in a mile. Knowing this, we can make the conversion from 2640 feet per hours to miles per hour:
(2640/5280)/1 hour = 0.5 miles / hour
-T.B.
It would become a larger bar that is all I can do without the graph
The complete question in the attached figure
we know that
perimeter=24 ft
[the perimeter of a rectangle]=2*8+2*x-----------> 16+2x
24=16+2x-------> 2x=24-16----------> 2x=8----------> x=4 ft
the answer is
the option C) x=4 ft
