Answer:
20.54%
Step-by-step explanation:
the first thing to know the percentage change, is to notice if the average increased or decreased, if it was initially 73 and then 88, we can say that increase, therefore the change is positive, now to calculate the exact change we must calculate the quotient of these numbers:
88/73 = 1.2054
which means that 0.2054 is the proportion of increase, to pass it to a percentage we must multiply by 100, that is:
0.2054 * 100 = 20.54%
which means that the percentage change was 20.54%
Answer:
A = 9x² + 48x + 65
Step-by-step explanation:
Area of a Square Formula: A = lw
Since a square's length is equal to its width, we simply plug it into the formula:
A = (3x + 8)(3x + 8)
Then we simply use FOIL to expand the distribution)
First - 3x(3x) = 9x²
Outside - 8(3x) = 24x
Inside - 8(3x) = 24x
Last - 8(8) = 64
Lastly, we combine like terms
9x² + 24x + 24x + 64
9x² + 48x + 64
Answer:
7:13
Step-by-step explanation:
It is not true
6pack = 6 pieces ?
6 pieces for $2.00 = $12 not $2.99
Devon should divide $2.99/6 ~~ $0.49
