PLEASE PLEASE HELP:: The scoop of an excavator holds 26 ft3 of sand. If the capacity of a freight car is 39 tons of sand and we know that 1 ft3 of sand weighs 0.5 tons, how many freight cars can be filled with 120 loads?

Answers

Answer 1

Answer:

40

Explanation:

Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion

26/x=1/0.5

If you simplify it, you should get x=13

Now that we know 26 ft3 of sand = 13 tons, we should multiply it with 120 number of loads

13*120=1560

Then, we have to divide 1560 by 39 which should give your answer 40

Hope this works!

Answer 2

Freight cars can be filled with 120 loads is 40

How is load percentage calculated?

The load factor percentage is derived by dividing the total kilowatt-hours (kWh) consumed in a designated period by the product of the maximum demand in kilowatts (kW) and the number of hours in the period.

Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion

26/x=1/0.5
