    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.

    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.
