To find the number of households that a power station can serve, we divide the total electricity generated by the power station by the electricity used by an average household.
Number of households = Total electricity generated / Electricity used by an average household
Using scientific notation:
Number of households = (2.496 * 10^11 kWh) / (1.04 * 10^4 kWh)
To divide these numbers in scientific notation, we subtract the exponents:
Number of households = (2.496 / 1.04) * (10^11 / 10^4)
Simplifying the calculation:
Number of households = 2.4 * 10^(11 - 4)
Number of households = 2.4 * 10^7
Therefore, the power station can serve 2.4 x 10^7 households.
An average American household uses about 1.04 x 104 kWh of electricity a year. If a power station generates 2.496 * 10 ^ 11 kWh per year, how many households can it serve? Write your answer in scientific notation, expressed to the exact decimal place.
