A light bulb consumes 600 watt-hours per day. How many watt-hours does it consume in 3 days and 18 hours

Lelechka [254]

Answer:

2250 watt-hours

Step-by-step explanation:

Okay, so we first need to find out how many watt-hours the light bulb consumes in 1 hours, so we need to divide 600 by 24 hours, which gives us a rate of 25 watt-hours per hour.

So if the light bulb consumes 600 hours per day, and it runs for 3 days, you multiply 600 by 3 to get 1800.

And because we know that it also consumes 25 watt-hours per hour, we multiply 25 and 18 together to get 450 hours.

Finally, you add 1800 and 450 together to get 2250 watt-hours.

Hope this helps :)

This is a literal equation.

Aleksandr [31]

Assuming this is the equation you want to operate on:
$v^{2} = (v_0)^{2} + 2\cdot a \cdot \Deltax$
$2\cdot a \cdot \Delta x = v^{2} - (v_0)^{2}$
$a = \frac{v^{2} - (v_0)^{2}}{2\cdot \Delta x}$
Before final operation we have to assume that x is not equal to 0. :)
