Answer:
250 boys
Step-by-step explanation:
We know that the ratio is 9:10 from girls to boys
Take 225 and divide it by 9
225 ÷ 9 = 25
So we know that 25 is a factor of 225
We can the number of boys and multiply it by 25 to get 250
If we put it in the ratio form:
225:250 = 9/10
Check work:
25 x 9 = 225
25 x 10 = 250
Answer:
x = 7 x = -7
Step-by-step explanation:
n^2 - 49 = 0
+49 +49
n^2 = 49

50 ft because you times 20 by 40 then you divide by 100 because that is the total percent
The amount to be paid after 3 years is $23,329.97.
<h3>What is Compound Interest?</h3>
In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
Given:
P= 20,000
r= 5.2%
t= 3 years
r = R/100
r = 5.2/100
r = 0.052 rate per year,
Now, solve for A
A = P
A = 20,000.00
A = 20,000.00
A = $23,329.97
