Lee watches TV for 2 hours per day. During that time, the TV consumes 250 watts per hour. Electricity costs (10 cents)/(1 kilowa
vladimir1956 [14]

Answer:

$1.5

Step-by-step explanation:

Lets us first calculate energy consumed by TV in 30 days.

Energy consumed by TV in one hour : 250 watts.

TV operated 2 hours a day

so energy consumer by TV in a day = 250 * 2 watts = 500 watts hour

Energy consumed by TV in 30 day = energy consumer by TV in a day * 30

         = 500*30 watts = 15,000 watt-hour

Convert total energy consumed in kilo watt hour  

we know that one kilowatt hour = 1000 watt-hour

Thus, 15,000 watt-hour = 15,000/1000 kilowatt-hour = 15 kilowatt-hour

________________________________

cost of electricity = 10 cents per   kilowatt-hour

cost of electricity for 15 kilowatt-hour = 15* cost of electricity for one  kilowatt-hour( which is 10 cents)

=>15*10 = 150 cents

As $1 = 100 cents

hence 150 cents = $150/100 = $1.5 .

Thus, it cost $1.5 to to operate for a month of 30 days.

What is the reason for each step in the solution of the equation? 19=5x−119=5x−1 drag and drop the reasons into the boxes to cor
shutvik [7]
The steps are duplicated.Then, first I will write the steps in the right form:

19 = 5x - 1

20 = 5x

4 = x

Now, I will write the steps with the justification

19 = 5x - 1.... start

20 = 5x ..... Reason: addtion property of equality (you get this by adding +1 to both sides of the previous equality)

4 = x .... Reason: division property of equality (you get this by dividing by 5 both sides of the previous equality)
