An average American household uses about 1.04x10^4 kWh (kilowatt hours) of electricity a year. If a power station generates 2.496x10^10 kWh per year, How many households can it serve? Write your answer in scientific notation, expressed to the exact as one place.

Answer 1

To find out how many households a power station can serve, we need to divide the total energy generated by the power station by the energy used by each household.

Total energy generated by the power station = 2.496x10^10 kWh
Energy used by each household = 1.04x10^4 kWh

Number of households = (Total energy generated by the power station) / (Energy used by each household)

Number of households = (2.496x10^10 kWh) / (1.04x10^4 kWh)

Number of households = (2.496/1.04) * (10^10/10^4) [Dividing the numbers and subtracting the exponents of 10]

Number of households = 2.4 * 10^6

Hence, the power station can serve approximately 2.4x10^6 households.

1. 2.4 x 10^6
2. 2.2 x 10^4
3. 5.1 x 10^8
4. 8 x 10^4
5. idk
