Apower plant has 4 tons of coal. a ton of coal produces 2,460 kilowatt hours of electricity. is this enough to power 9 light bulbs for a year? explain

Assuming 100 kw bulb

We'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 kwh

Since the produced electricity is bigger so it is enough

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
