A 60-watt light bulb uses 60 watt hours of electricity in 1 hour. Suppose everyone in the United States left one unneeded 60 watt light bulb on for one hour every day for a year.
9. Electricity is billed in kilowatt hours. So 60 watt hours is equal to sixty
divided by one thousand. Express the electricity used by a 60-watt light
bulb in one hour in kilowatt hours in scientific notation.
10. Express the number of days in a year in scientific notation.
11. There are about 315,000,000 people in the United States. Write that
number in scientific notation.
12. Now find how many kilowatt hours of electricity would be wasted if
every person in the United States left on one unneeded 60-watt light
bulb one hour a day for a whole year. Express your answer in both
scientific notation and standard notation.
13. The average household uses about 15,000 kilowatt hours per year.
How many households could use that wasted electricity from item 12
and have light for a year? Express your answer in standard notation.
