Answer: 3 is the nearest integer.
Step-by-step explanation:
The square root of 12 is between 3 and 4
9 and 16 are perfect squares. Their roots are 3 & 4 respectively. 12 is about halfway between, so a good approximation would be 3 1/2, but the question asks for the nearest integer, not the nearest rational number.
C is the correct answer.<span />
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)
