percent of increase for a population that changed from 25,000 to 30,000
Increase in population = 30,000 - 25,000 = 5000
So, the increase in population is 5000
To find percent of increase , we divide the increase in population by initial population.
So percent of increase = * 100
= 0.2 * 100
= 20 %
20% of increase for a population that changed from 25,000 to 30,000.
I'm not really sure but I know that the answer is <u>definitely not</u> 0.25 or 0.5.
Answer:
calories
Step-by-step explanation:
Given: The racer moves at miles per hour expends energy at a rate of calories per hour.
To find: Energy in calories, required to complete a marathon race miles at this pace.
Solution: We have,
The racer moves at miles per hour.
The racer expends energy at a rate of calories per hour.
So, energy expended while moving miles calories.
Now, energy expended while moving mile calories.
So, energy expended while moving miles calories.
Hence, calories of energy is required to complete a marathon race miles at this pace.

Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
