Perimeter is all sides added up.
So, we know the width is 19ft and the length is x feet. We also know that the perimeter is 87 feet.
What we can do is make an equation to solve for x.
2x + 2(19) = 87
First, multiply 2 and 19.
2 x 19 = 38
2x + 38 = 87
Next, subtract 38 from both sides to move 38.
2x = 87 - 38
2x = 49
Lastly, divide both sides by 2 to get the value of x.
x = 49/2
x = 24.5
Thus, the length of the rectangle is 24.5ft
We can plug it into our equation to check if its correct.
2(24.5) + 2(19) = 87
24.5 x 2 = 49
2 x 19 = 38
49 + 38 = 87
Answer:
C≈40.84
Step-by-step explanation:
C = 2πR
I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.
We need 6.5% to a decimal so..
6.5% /100 = 0.065
$21.30 X 0.065 = 1.3845 tax on the shirt
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845
Answer = $22.68
