Question

If a cow has a mass of 9 × 10^2

Answer 1

Answer:

a) The blue whale has about 200 times more mass

Step-by-step explanation:

(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)

... = (1.8/9)×10^(5-2)

... = 0.2×10^3

... = 200

The blue whale has about 200 times as much mass as a cow.

Answer 2

Answer:

a) The blue whale has about 200 times more mass.

Step-by-step explanation:

A cow has a mass of 9 × 10^2 kilograms, and a blue whale has a mass of 1.8 × 10^5 kilograms.

The blue whale is about $\frac{1.8\times10^{5}}{9\times10^{2}}$ times more than cow.

= $\frac{180000}{900}$

= 200

Hence, the answer is a) The blue whale has about 200 times more mass.
