Question

Question 1 - You need to FIRST convert the adult male blue whale's weight to kg.1. Two of the largest mammals on earth are the blue whale and the African elephant. An adult male blue whaleweighs about 170 tonnes or long tons. (1 tonne - 1000 kg)Show that the weight of an adult blue whale is 1.7 x 105 kgYour answer

Answer 1

we have

170 tonnes

1 tonne - 1000 kg

Convert tonnes to kg

Multiply the weight in tonnes by 1000

so

170 tonnes=170(1,000)=170,000 kg

Convert to scientific notation.

170,000=1.7(100,000)=1.7 x 10^5 kg
