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 generated electricity by the electricity used by each household.
Total generated electricity per year: 2.496×10^10 kWh
Electricity used by each household per year: 1.04×10^4 kWh
To calculate the number of households the power station can serve, we divide the total generated electricity by the electricity used by each household:
Number of households = (2.496×10^10 kWh) / (1.04×10^4 kWh)
To divide numbers in scientific notation, we subtract the exponents of the numerator and denominator, while keeping the same base (10). The result is expressed in scientific notation:
Number of households = (2.496 / 1.04) × (10^10 / 10^4) = 2.4 × 10^(10-4) = 2.4 × 10^6
Therefore, the power station can serve approximately 2.4 × 10^6 households.
There are about 1.6×103 meters in a mile. About how many miles are there in 3.52×107 meters? Write your answer in scientific notation, expressed to the exact decimal place.
To find out how many miles there are in 3.52×10^7 meters, we need to divide the given distance in meters by the number of meters in a mile.
Number of meters in a mile: 1.6×10^3 meters
To calculate the number of miles, we divide the given distance in meters by the number of meters in a mile:
Number of miles = (3.52×10^7 meters) / (1.6×10^3 meters)
To divide numbers in scientific notation, we subtract the exponents of the numerator and denominator while keeping the same base (10). The result is expressed in scientific notation:
Number of miles = (3.52 / 1.6) × (10^7 / 10^3) = 2.2 × 10^(7-3) = 2.2 × 10^4
Therefore, there are approximately 2.2 × 10^4 miles in 3.52×10^7 meters.
An online data storage facility has 1.326×1013 bytes of storage available. It has 2.6×104 customers. How many bytes of storage can each customer use? Write your answer in scientific notation, expressed to the exact decimal place.(1 point)
To find out how many bytes of storage each customer can use, we need to divide the total available storage by the number of customers.
Total available storage: 1.326×10^13 bytes
Number of customers: 2.6×10^4
To calculate the bytes of storage each customer can use, we divide the total available storage by the number of customers:
Bytes of storage per customer = (1.326×10^13 bytes) / (2.6×10^4)
To divide numbers in scientific notation, we subtract the exponents of the numerator and denominator while keeping the same base (10). The result is expressed in scientific notation:
Bytes of storage per customer = (1.326 / 2.6) × (10^13 / 10^4) = 0.510×10^(13-4) = 0.510×10^9
However, since we want the answer expressed to the exact decimal place, we convert 0.510×10^9 to scientific notation with the decimal moved to the right place:
Bytes of storage per customer = 5.10×10^8
Therefore, each customer can use approximately 5.10×10^8 bytes of storage.
A public aquarium is being built to contain neon tetras. Each neon tetra needs 1.25 gallons of water. The aquarium will contain 1×105 gallons of water. How many tetras can it house? Write the answer in scientific notation.(1 point)
To determine how many neon tetras can be housed in the aquarium, we need to divide the total gallons of water by the amount of water needed for each neon tetra.
Amount of water needed for each neon tetra: 1.25 gallons
Total gallons of water in the aquarium: 1×10^5 gallons
To calculate the number of tetras, we divide the total gallons of water by the amount of water needed for each neon tetra:
Number of tetras = (1×10^5 gallons) / (1.25 gallons)
To divide numbers in scientific notation, we subtract the exponents of the numerator and denominator while keeping the same base (10). The result is expressed in scientific notation:
Number of tetras = (1 / 1.25) × (10^5 / 1)
Simplifying the calculation gives:
Number of tetras = 0.8 × 10^5 = 8 × 10^4
Therefore, the aquarium can house approximately 8 × 10^4 neon tetras.
A feather weighs 0.0082 g. How many feathers would you need to make a weight of 4.1×103 g? Write the answer in scientific notation.(1 point)
To determine how many feathers would be needed to make a weight of 4.1×10^3 g, we need to divide the desired weight by the weight of each feather.
Weight of each feather: 0.0082 g
Desired weight: 4.1×10^3 g
To calculate the number of feathers, we divide the desired weight by the weight of each feather:
Number of feathers = (4.1×10^3 g) / (0.0082 g)
To divide numbers in scientific notation, we subtract the exponents of the numerator and denominator while keeping the same base (10). The result is expressed in scientific notation:
Number of feathers = (4.1 / 0.0082) × (10^3 / 1)
Simplifying the calculation gives:
Number of feathers = 500 × 10^3 = 5 × 10^5
Therefore, you would need approximately 5 × 10^5 feathers to make a weight of 4.1×10^3 g.
