Final answer:
To find the weight of a 5 inch length of the cable, you can set up a proportion using the given weight of a 2-foot length. Then, convert the weight in pounds to ounces by multiplying by 16. Rounded to the nearest tenth of an ounce, the weight of a 5 inch length of the cable would be approximately 50 ounces.
Step-by-step explanation:
To find the weight of a 5 inch length of the cable, we need to first find the weight of a 2-foot length of the cable. We are given that a 2-foot length of the cable weighs 15 pounds. We can set up a proportion to find the weight of a 5 inch length:
2 feet = 24 inches
15 pounds = x pounds
Using cross multiplication, we can solve for x:
24x = 15 * 5
x = 15 * 5 / 24
x ≈ 3.125 pounds
Finally, we can convert pounds to ounces. Since there are 16 ounces in a pound, we can multiply the weight in pounds by 16:
3.125 pounds * 16 ounces = 50 ounces
Rounded to the nearest tenth of an ounce, a 5 inch length of the cable would weigh approximately 50 ounces.
