Answer:
x = 114 inches
Step-by-step explanation:
The ratio of height to shadow length will be identical
x/72 = 76/48
x = 76(72)/48 114 inches
The answer is (3:4) and use a period
Answer:
Load that the beam can support = 7923.81 pounds
Step-by-step explanation:
The safe load L, of the beam varies directly as the product of the width and the square of the height.
L∝ (w × h²)
And varies inversely as the length of the wooden beam.
L ∝ 

where k = proportionality constant
If w = 3 inches, h = 5 inches, l = 120 inches and L = 2600 pounds
Then, 


k = 4160
If w = 5 inches, h = 8 inches and l = 168 inches
L = 7923.81 pounds
