Answer:
(1) A. 1 × 10^-4
(2)A. 8 × 10³
(3)B. 8 × 10⁷
Explanation:
(1)
Mass of a worker Bee = 0.00011 kg
Since 1 × 10^-4 is = 1/10⁴ or 1/10000 or 0.0001 kg, Option A 1 × 10^-4 will be the correct answer
(2)
Mass of an African Elephant = 8139kg
Since 8 × 10³ is = 8 × 1000 or 8000kg, Option A 8 × 10³ will be the correct answer
(3) Mass Of a worker bee = 0.00011 kg
Mass of an African Elephant = 8139 kg
8139/0.00011 = 73,990,909.090
This value is the closest to 8 × 10⁷ or 8 × 10000000 or 80,000,000, Option B 8×10⁷ is the correct answer
