Two of largest mammals on earth are the blue wale and the African elephant. An adult male blue whale weighs about 170 tonnes or
long tones. (1 tonne =1000 kg) Show that the weight of an adult blue whale is 1.7 * 10^5 kg.
1 answer:
Weight is 1.7 × 10^5 kg
Step-by-step explanation:
- Step 1: Given that the weight of the blue whale = 170 tonnes
- Step 2: Convert the number of tonnes into kg.
⇒ 170 tonnes = 170 × 1000 (1 tonne = 1000 kg)
⇒ 170 tonnes = 17 × 10^4 kg
- Step 3: Convert it into standard format, that is with just one decimal point.
⇒ 17 × 10^4 = 1.7 × 10^5 kg (Dividing and multiplying by 10 on both sides)
