13 143rds would be written as 13/143.
To calculate growth rate, start by subtracting the past value from the current value. Then, divide that number by the past value. Finally, multiply your answer by 100 to express it as a percentage.
<u>Explanation:</u>
The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Annual Growth Rate of Population refers to the rate at which the number of individuals in a given popular increase over a year, expressed as a fraction of the initial popular of the previous years. The annual percentage growth rate of population is the percent growth divided by the number of years.
Answer:
27 and 23
Step-by-step explanation:
We can solve this problem as a system of equations. X is the first number and Y is the second number.
The first equation is x+y = 50 and the second equation is x-y=4
Now we solve the system, using elimination method:
x+y=50
x-y=4
2x = 54
x = 54/2
x = 27
And from any of the equations we can find Y
27 + y = 50
y = 50 - 27
y = 23
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- <em>When we listen to the word "quotient", it means the solution to a division problem. </em>
- <em>An unknown number that has been multiplied by 2 is in the numerator because it came before the 7 in the statement. </em>
- <em>The number "7" is in the denominator because it came after the 2x in the statement. </em>
- <em>The word "is" represents an equal sign.</em>
- <em>The solution to the division problem (quotient) is 20. </em>
<u><em>If we put these clues together, we get 2x/7 = 20 as our translated equation.</em></u>
<u>Hence, our algebraic statement is 2x/7 = 20. The key is to listen to the statement. </u>

Answer:
A and E
Step-by-step explanation:
9^3 / 9^3
Same number on top and bottom so 1 is an answer
look at the exponents, when dividing with exponents, you just subtract them, so it could also be 9^0, which is also 1
