Step-by-step explanation:
Answer: 1) D
2) C
Step-by-step explanation:
1. The blue algae has an initial mass of 20 kg and doubles its mass every hour. Then after t hours, the mass of blue algae is
2. The green algae has an initial mass of 160 kg and grows at a constant rate of 0.20 kg per minute. Then after t hours (60t minutes), the mass of green algae is
Part I) At t=3:
The mass of green algae has 196-160=36 kg more mass at 3 hours.
Part II) At t=4:
The blue algae has 320-208=112 kg more mass at 4 hours.
The correct answer is reflection
Answer:
A = 13.23 m²
Step-by-step explanation:
A = bh
Where,
A = area of the parallelogram
b = base of the parallelogram
h = height of the parallelogram
From the question, assume
b = 2.1 m
h = 6.3 m
A = bh
= 2.1 m × 6.3 m
= 13.23 m²
A = 13.23 m²
