Question

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 104

kg.
The mass of a male polar bear is about 700 kg, or 7 x 102 kg.
About how many times more massive is the right whale than the polar bear?
O A. 1x 10-2 times
O B. 1x 102 times
O C. 69300 times
OD:: 12 times

Answer 1

Answer B:
`1*10^2` times

Explanation:

To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:

`(7*10^4)/(7*10^2) = (7*10^2*10^2)/(7*10^2)=1*10^2` times

Therefore our answer agrees with the one shown as answer B.
