An average American household uses about 1.04×104 kWh (kilowatt hours) of electricity a year. If a power station generates 2.496×1010 kWh per year, how many households can it serve? Write your answer in scientific notation, expressed to the exact decimal place.(1 point)

To find out how many households a power station can serve, we need to divide the total amount of electricity generated by the power station by the amount of electricity used by an average American household.
Number of households = Total electricity generated / Electricity used per household
Number of households = (2.496×10^10 kWh) / (1.04×10^4 kWh)
To divide two numbers in scientific notation, we subtract the exponents and divide the coefficients:
Number of households = (2.496 / 1.04) × 10^(10-4)
Number of households = 2.4 × 10^(10-4)
Number of households = 2.4 × 10^6
Therefore, the power station can serve approximately 2.4 × 10^6 households.
To find out how many households a power station can serve, we need to divide the total amount of electricity generated by the power station by the average amount of electricity used by each household.
Given:
Total electricity generated by the power station = 2.496×10^10 kWh
Average electricity used by each household = 1.04×10^4 kWh
To determine how many households can be served, we can use the following formula:
Number of households = Total electricity generated / Average electricity used per household
Number of households = (2.496×10^10 kWh) / (1.04×10^4 kWh)
To divide these numbers in scientific notation, we need to subtract the exponents and divide the coefficients:
Number of households = (2.496 / 1.04) × 10^(10 - 4)
Simplifying the expression within the parentheses:
Number of households = 2.4 × 10^6
Therefore, the power station can serve approximately 2.4 × 10^6 households.
To find out how many households a power station can serve, we need to divide the total amount of electricity generated by the power station by the amount of electricity used by an average household.
The total amount of electricity generated by the power station is given as 2.496x10^10 kWh.
The amount of electricity used by an average American household is given as 1.04x10^4 kWh.
To find the number of households that can be served, we divide the total electricity generated by the electricity used per household:
Number of households = Total electricity generated / Electricity used per household
Number of households = (2.496x10^10 kWh) / (1.04x10^4 kWh)
To divide the numbers in scientific notation, we subtract the exponents:
Number of households = 2.496x10^10 / 1.04x10^4
Simplifying the calculation, we divide the coefficients:
Number of households = 2.4x10^(10-4)
Number of households = 2.4x10^6
Therefore, the power station can serve approximately 2.4x10^6 households.
