A light bulb consumes 5040 watt-hours in 5 days and 6 hours. How many watt-hours does it consume per day?

OpenStudy (jdoe0001):

how many hours are there in 5 days in 6 hours?

OpenStudy (anonymous):

126?

OpenStudy (anonymous):

it consumes 42 watt hours per day

OpenStudy (jdoe0001):

so we can say it really consumes 5,040 watt-hours in 126 hours if that's the case, how many does it consume per hour?

OpenStudy (anonymous):

nvm its not 42

OpenStudy (anonymous):

To Find That Don't We Divide By Like 60 Mins In An Hour?

How Did You Get 960 @tebowman8

OpenStudy (jdoe0001):

well, no :/, recall we now know that it consumes 5,040 in 126 hours our unit is already in hours, we don't need it in minutes

OpenStudy (jdoe0001):

if it consumes 5040 in 126 hours how much will it consume in 1 hour?

OpenStudy (anonymous):

40? . . . .

OpenStudy (anonymous):

i did 5040 / 5.25 = 960, and 5.25 is 6 hours

OpenStudy (jdoe0001):

so if the bulb consumes 40 in 1 hour, how many will it consume in 24 hours? 1 day = 24 hours

OpenStudy (anonymous):

960 @jdoe0001

OpenStudy (jdoe0001):

there, as @tebowman8 said :)

OpenStudy (anonymous):
