Choose all the comparisons that are true.
1) 0.2 < 0.5
2) 0.9 < 0.5
3) 0.1 = 1
4) 0.6 > 1
5) 0.6 > 0.55

1, 5

Step-by-step explanation:

0.2 is less than 0.5

0.9 is greater than 0.5

0.1 does NOT equal to 1 but 1.0 does

0.6 is less than 1

0.6 is greater than 0.55

there should be no gaps so 0.6 would be 0.60.

 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.
