A public aquarium is being built to contain neon tetras. Each neon tetra needs 1.25 gallons of water. The aquarium will contain 1×10^5 gallons of water. How many tetras can it house? Write the answer in scientific notation.(1 point)
$$
The number of tetras that can be housed in the aquarium can be found by dividing the total number of gallons of water in the aquarium by the number of gallons of water needed per neon tetra:
Number of tetras = Total gallons of water / Gallons of water per tetra
Number of tetras = 1×10^5 gallons / 1.25 gallons per tetra
Number of tetras = 8×10^4 tetras
Therefore, the aquarium can house 8×10^4 tetras.
To find out how many neon tetras can be housed in the aquarium, we need to divide the total amount of water in the aquarium by the amount of water each neon tetra needs.
The total amount of water in the aquarium is given as 1×10^5 gallons.
Each neon tetra needs 1.25 gallons of water.
So, we can calculate the number of neon tetras that can be housed in the aquarium as follows:
1×10^5 gallons ÷ 1.25 gallons = 8×10^4
Therefore, the aquarium can house 8×10^4 neon tetras.
To find the number of tetras that can be housed in the aquarium, we need to divide the total volume of the aquarium by the volume required for each tetra.
The total volume of the aquarium is given as 1×10^5 gallons.
The volume required for each tetra is given as 1.25 gallons.
To calculate the number of tetras, we divide the total volume of the aquarium by the volume required for each tetra:
Number of tetras = Total volume of aquarium / Volume required per tetra
Number of tetras = (1×10^5 gallons) / (1.25 gallons)
To divide the numbers, we need to divide the numerical parts and subtract the exponents:
Number of tetras = 8×10^4
Therefore, the aquarium can house 8×10^4 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 the number of feathers needed to reach a weight of 4.1×10^3 g, we need to divide the target weight by the weight of a single feather:
Number of feathers = Target weight / Weight per feather
Number of feathers = 4.1×10^3 g / 0.0082 g
To divide the numbers, we need to divide the numerical parts and subtract the exponents:
Number of feathers = 5×10^5
Therefore, you would need 5×10^5 feathers to make a weight of 4.1×10^3 g.
