Is there a picture for this word problem?
No, the answer would be B. “Either the mean or the median. The values are about the same.”
(Hope this helped!)
12/15 as a percent is 80% and 12/15 as a decimal is 0.8
Ratio of width to length: W/L = 3/5
5W = 3L .........(a)
Perimeter = 2*(L+W) = 80
2*(L+W) = 80
(L+W) = 80/2. Divide both sides by 2.
L+W= 40......(b)
5W = 3L
L + W = 40 Multiply both sides by 5.
5*(L+W) = 5*40
5L+5W = 200. Recall from (a) 5W = 3L
5L + 3L = 200
8L = 200
L = 200/8
L = 25.
5W = 3L
5W = 3*25
W = 3*25/5
W = 15.
Therefore, the length, L = 25 and width , W = 15.

P(x)=-0.02x^2 +520x -200x -100,000
P(x)=-0.02x^2 +320x -100,000
P '(x)=-0.04x+320=0
x=320/0.04=8000
P(8000)=1,180,000
Your final answer would be </span><span>1,180,000 </span>
