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:

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!

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

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
