Answers

Answer 1
Answer:

(8.19)/(4.20)= (819)/(420)

(819)/(420)=(819/7)/(420/7)=(117)/(60)=(117/3)/(60/3)=(39)/(20)

Your answer is (39)/(20) or 1.95.

A 120 watt light bulb uses about 0.1 kilowatt of electricity per hour.if electricity costs $0.20 per kilowatt hour how much does it cost to have a bulb on for an hour?

Answers

A 120 watt light bulb uses about 0.1 kilowatt of electricity per hour.if electricity costs $0.20 per kilowatt hour. Let's solve how much does it cost to have a bulb on for an hour. => 120 watt = 0.1 kilowatt per hour which costs 0.20 per kilowatt per => 0.1 kilowatt per hour * 0.20 = 0.02 dollars in an hour.

Answer:

$0.02 is the cost to have the bulb on for an hour

Step-by-step explanation:

A 120 watt light bulb uses about 0.1 kilowatt of electricity per hour

We can assume 1 kilowatt per hour = 1 unit

So total units of electricity consumed in 1 hour = 0.1 × 1

= 0.1 kilowatt hour or 0.1 unit

Since cost of one unit or 1 kilowatt hour is = $0.20 per unit or kilowatt hour.

Therefore, total cost to have this bulb on for an hour = Number of units consumed by the light bulb × per unit cost

= 0.1×0.20

= $0.02

$0.02 is the cost to have the bulb on for an hour.
