Answer:

It costs Laura $ 5,184.86 to heat her house one day.

A 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

Step-by-step explanation:

Given that a kilowatt hour means 1 kilowatt of electricity used continuously for 1 hr, and the electric utility company in Laura's town charges $ 0.06001 for each kilowatt hour used, and Laura heats her house with three electric heaters that each use 1200 watts, to determine how much does it cost to heat a house in one day and how many hours would a 75 watt lightbulb have to stay on to result in one dollar for electricity charges the following calculations must be performed:

(3 x 1200 x 24) x 0.06001 = X

(3600 x 24) x 0.06001 = X

86400 x 0.06001 = X

5,184.86 = X

Therefore, it costs Laura $ 5,184.86 to heat her house one day.

1 watt = 0.001 kilowatt

75 watt = 0.075 kilowatt

1 / 0.075 = 13.333

1 / 0.06001 = 16,663

13,333 x 16,663 = 222.18

Therefore, a 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

A rental company charges costumers a 14.75 fee plus $0.15 per smile to rent a moving van after returning the moving van a custom
kumpel [21]

Step-by-step explanation:

I guess, the question is, how many miles were driven ?

if that is the case, then

we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.

so, 50.45 - 14.75 = $35.70

that is the actual cost for the driven miles.

how many miles ?

well, how often do $0.15 fit into $35.70 ?

35.7 / 0.15 = 238 miles.

this customer had been driving the moving van for 238 miles.
