Here is how you solve
4x+12-12=0-12
4x=-12
x=-3
The correct answer is 75,000. Hope this helps!!!! ;)
I am not answering all the questions.
I will only do the first one.
A = pir^2
A = pi(6)^2
A = 36pi
You do the rest.
Your answer is 2,200 pupils.
If 990 is equal to 45% of the total amount of pupils, then to find 1% we can divide both 45 and 990 by 45.
990 ÷ 45 = 22, which is 1%, so then we multiply 22 by 100 to get 100% of the pupils, which gives us 2,200.
I hope this helps!
Answer:
5,040.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 8000(1 + (0.07 × 9)) = 13040
A = $13,040.00
The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 7% per year for 9 years is $13,040.00.
