To find how many miles there are in 3.52×10^7 meters, we can simply divide the given number of meters by the number of meters in a mile.

3.52×10^7 meters ÷ 1.6×10^3 meters/mile = 2.2×10^4 miles

Therefore, there are approximately 2.2×10^4 miles in 3.52×10^7 meters.

To find the number of bytes of storage each customer can use, we can divide the total available storage by the number of customers.

1.326×10^13 bytes ÷ 2.6×10^4 customers = 5.1×10^8 bytes

Therefore, each customer can use approximately 5.1×10^8 bytes of storage.

To find the number of tetras that can be housed in the aquarium, we can divide the total gallons of water in the aquarium by the amount of water each tetra needs.

1×10^5 gallons ÷ 1.25 gallons/tetra = 8×10^4 tetras

Therefore, the aquarium can house approximately 8×10^4 tetras.

To find the number of feathers needed to reach a weight of 4.1×10^3 g, we can divide the desired weight by the weight of each feather.

4.1×10^3 g ÷ 0.0082 g/feather = 5×10^5 feathers

Therefore, you would need approximately 5×10^5 feathers to reach a weight of 4.1×10^3 g.
