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.
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)

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.
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.
