100 total people......35 exercise in the morning....45 in the afternoon...and 20 at night
Jim is correct.....
35/100 is the ratio of people who exercise in the morning to total people.
45/100 is the ratio of afternoon exercisers to total people
20/100 is the ratio of night exercisers to total people
The equation to find the air pressure (P(h)) at a height above sea level (h) is given by
Where,
- P(h) is the new pressure at height h
is the air pressure at sea level, and- h is the height (measured in meters).
We want to know the new pressure that is 65% of 
. So we should substitute 
in P(h) (new pressure) to get the equation:
. Answer choice B is the correct one.
ANSWER: B
Here are a few rules with exponents that you need to know:
- Dividing exponents of the same base:
For this, divide:
<u>Your final answer is 
</u>
M=slope
In this case the slope would be $25
y=mx+b
y=25x+45
Answer: m=25
Old
9.99×55
=549.45
New
10.68×55
=587.4
((10.68÷9.99)−1)×100
=6.9%
