The constant rate of continuous growth, k, for this population is equal to 2.11935%. And the population will reach 250,000 people in 24.36 years.
For solving this question, you should apply the Population Growth Equation.
<h3>Population Growth Equation</h3>
The formula for the Population Growth Equation is:
Pf= future population
Po=initial population
r=growth rate
t= time (years)
STEP 1 - Find the constant rate of continuous growth, k, for this population.
For this exercise, you have:
Pf= future population= 185,000 in 2020.
Po=initial population =150,000 in 2010.
r=growth rate= ?
t= time (years)=2020-2010=10
Then,
STEP 2 - Find the <em>t</em> for population 250,000 people.

When adding or subtracting fractions that have a common denominator, simply subtract the numerators (top numbers) by each other. However, to subtract fractions with unlike denominators, find the LCD or "least common denominator". That is the lowest number both denominators can equate to.
[/tex]
The LCD of 8 and 18 is 72.
Some of the multiples of 8 are: 8, 16, 24, 32, 64, 72, 80, 88, 96, 104...
The multiples of 18 are: 18, 36, 54, 72, 90
The lowest common multiple is 72.
Multiply each fraction by what it takes for the denominator to equal 72.
8 multiplied by what number = 72
8*9=72
18 multiplied by what = 72
18*4=72
Multiply both fractions respectively
13/18*4= 13*4/72
5/8*9 = 5*9/72
52/72 - 45/72
Simplify
52-45/72
7/72
This being the answer for the original expression

Answer:
44%
Step-by-step explanation:
For these types of problems, look at the totals. We know that there are 0.44 out of 1 eighth graders. Since it doesn't specify how the 8th grader is dropped off, we take 0.44 and divide it by 1 (the total). We get 0.44, but since it's most likely asking for percentages, multiply that by 100.
Here is a trick I always use:
Get rid of both zeros in100 for now
So just do 697*1 which is just 697
Now add the two zeros to your answer to get 69,700 which is the final answer
