She is not correct, because $3.00 divided by 6 is 50 cents, so by using that equation she could evaluate that she is wrong and find the correct answer.
We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
Answer:
A=3 because 7+3=10
Step-by-step explanation:
12 - 15 ÷ 3 + 9
Following BODMAS = Bracket Order Division Multiplication Addition Subtraction
Division comes before Addition and Subtraction, so we carry out Division first.
12 - 15 ÷ 3 + 9, 15 ÷ 3 = 5
12 - 5 + 9
7 + 9
16
I hope you find this explanation useful.
