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 per year by the amount of electricity used by each household per year.
Given:
Total electricity generated per year = 2.496×10^10 kWh
Electricity used by an average American household per year = 1.04×10^4 kWh
To find the number of households served, we divide the total electricity generated by the electricity used by each household:
Number of households served = Total electricity generated / Electricity used by each household
Number of households served = (2.496×10^10 kWh) / (1.04×10^4 kWh)
Dividing the numbers and subtracting the exponents, we get:
Number of households served = 2.4×10^6 households
So, 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 an American household.
Given:
Total electricity generated by the power station = 2.496×1010 kWh
Average electricity used by an American household per year = 1.04×104 kWh
To find the number of households served:
Number of households = Total electricity generated / Average electricity used by one household
Let's calculate it step by step:
1. To divide the numbers in scientific notation, we subtract the exponents of 10 and divide the numbers:
(2.496×1010 kWh) / (1.04×104 kWh)
2. Dividing the numbers, we get:
2.496×106
Therefore, a power station that generates 2.496×1010 kWh per year can serve approximately 2.496×106 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 a household.
Total electricity generated by the power station = 2.496×1010 kWh
Average electricity used by a household = 1.04×104 kWh
Number of households the power station can serve = (Total electricity generated by the power station)/(Average electricity used by a household)
Number of households the power station can serve = (2.496×1010 kWh)/(1.04×104 kWh)
Number of households the power station can serve = 2.4×106
Expressed in scientific notation, to the exact decimal place, the power station can serve approximately 2.4×106 households.
