Answer:
12%
Step-by-step explanation:
Percentage increase of something is often represented in a formula of a format like this:
X=Ar^t
Where X represents the total amount after t years.
A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead. t is the time, no. of years in this case, that has elapsed since 1996.
This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.
Hope this helped!
Answer:
C. (16y + 7z)
Step-by-step explanation:
9y + 11z + 7y - 4z
1. Simplify the y's: 9y + 7y = 16y
16y + 11z - 4z
2. Simplify the x's: 11z - 4z = 7z
16y + 7z
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
The answer will be C-115.75
You have to times 23 by 5.50 which you will get 126.50
Then you have to subtract that by 10.75
You will get C
Step-by-step explanation:
3(x+3) - 2(x+2) =
3x + 9 - 2x - 4 =
x + 5
always remember the rules when combining signs and operations (therefore it is -4 at the end after doing the multiplications) :
++ = +
+- = -
-+ = -
-- = +
