When sending a rectangular package through the U.S. Postal Service, the combined length and girth (perimeter of the cross sectio
n) cannot exceed 108 inches. Up to what length can a package be if the width and height are 10 and 15 inches?
1 answer:
Let W = width of package
Let H = height of package
Let L = length of package
The perimeter cab be one of the following:
P = 2(L + W), or
P = 2(L + H)
The perimeter of the cross section cannot exceed 108 in.
When the width is 10 in, then
2(L + 10) <= 108
L + 10 <= 54
L <= 44 in
When the height is 15 in, then
2(L + 15) <= 108
L + 15 <= 54
L <= 39 in
To satisfy both of these conditions requires that L <= 39 in.
Answer: 39 inches

Answer:
P = 5.5x + 9
Step-by-step explanation:
P = 5x + (0.3x + 24) + (0.2x - 15)
reduced
P = 5.5x + 9
Answer:
O= 90 because it is a right angle, 360 degrees (which is the whole circle) minus (50+90), equals 220.
