the average weight of a blue whale is 4 x 10^5 pounds. the average weight of an elephant is 1 x 10^4 pounds. approximately how many times heavier is a blue whale than an elephant in pounds?

o 4 times heavier
o 2 times heavier
o 40 times heavier

To find out how many times heavier a blue whale is compared to an elephant, we need to divide the weight of the blue whale by the weight of the elephant.

Blue whale weight: 4 x 10^5 pounds
Elephant weight: 1 x 10^4 pounds

So, the calculation would be:

(4 x 10^5 pounds) / (1 x 10^4 pounds)

Simplifying the calculation gives us:

(4 x 10^5) / (1 x 10^4) = 4 x 10^(5-4) = 4 x 10^1 = 4 x 10

Therefore, a blue whale is 40 times heavier than an elephant, so the answer is:

o 40 times heavier
