Question

One ton of uranium and 16,000 tons of oil both produce 40 million kilowatts of electricity

To produce 60 million kilowatts of electricity,___tons of uranium or___tons of oil is needed

Answer 1

100 kw bulbWe'll start by figuring out how much energy in

kilowatt-hours the light bulb uses per year. We multiply how much power it uses

in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours

or 876 kWh x 9 bulbs = 7884 kWh The electricity produced by 4 tons x 2460

kWh/ton = 9840 kwhSince the produced electricity is bigger so it

is enough

Answer 2

To produce 60 million kilowatts of electricity, 1.5 tons of uranium or 24,000 tons of oil is needed.

Step-by-step explanation:

To solve this question we have to use cross-multiplication. One ton of uranium and 16,000 tons of oil both produce 40 million kilowatts of electricity, and we have to know how much uranium and oil would produce 60 million kilowatts of electricity, so:

-Uranium:

40,000,000 = 1

60,000,000 = X

(60,000,000 x 1) / 40,000,000 = X

1.5 = X

To produce 60 million kilowatts of electricity, 1.5 tons of uranium is needed.

-Oil:

40,000,000 = 16,000

60,000,000 = X

(60,000,000 x 16,000) / 40,000,000 = X

24,000 = X

To produce 60 million kilowatts of electricity, 24,000 tons of oil is needed.
