Answer:
Step-by-step explanation:
a) The maximum weight M that can be supported by a beam is jointly proportional to its width w and the square of its height h, and inversely proportional to its length L. If k represent the constant of proportionality, the expression would be
M = kwh²/L
b) if w = 4 inches, h = 6 inches, length = 12 ft
1 foot = 12 inches
12 ft = 12 × 12 = 144 inches. Therefore
L = 144 inches
M = 4800lb
Substituting these values into
M = kwh²/L, it becomes
4800 = (k × 4 × 6²)/144
4800 = k
The equation becomes
M = 4800wh²/L
c) if L = 10ft(10 × 12 = 120 inches),
h = 10 inches
w = 3 inches, then
M = 4800 × 3 × 10²/120
M = 12000 lbs
Answer:
22 hours
Step-by-step explanation:
take 62.50 divided by 5 which will get you 12.5 then multiply until you get to $275 for example 12.5 times 22
First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus -∞ < x < +∞
Answer:
7 2/3 more pounds of deli meat
Step-by-step explanation:
Brandon needs 12 pounds of deli meat to make a sandwich tray.
He brought 4 1/3 pounds of ham.
The amount of deli meat that he still needs is calculated as:
12 pounds - 4 1/3 pounds.
= 7 2/3 pounds
