1. Answer: 60 minutes
<u>Step-by-step explanation:</u>
Faucet A: 140 milliliters/min = 0.140 liters/min
Faucet B: 100 milliliters/min = 0.100 liters/min
Let x represent the amount of time
Faucet A + Faucet B = Full fish tank
0.140x + 0.100x = 14.4
0.240x = 14.4
x = 60

2. Answer: 40 minutes
<u>Step-by-step explanation:</u>
Quantity currently in tank: 4.8 liters
Water In: 150 milliliters/min = 0.150 liters/min
Water Out: 270 milliliters/min = 0.270 liters/min
Let x represent the amount of time
Qty in tank + In - Out = Empty fish tank
4.8 + 0.15x - 0.27x = 0
- 0.27x = -4.8
x = 40
Answer and Step-by-step explanation:
To find the sequence, we must plug in values for n and solve, starting with 0.
f(0) = ⁻13 - 2(0) = ⁻13
f(1) = ⁻13 - 2(1) = ⁻13 - 2 = ⁻15
f(1) = ⁻13 - 2(2) = ⁻13 - 4 = ⁻17
f(1) = ⁻13 - 2(3) = ⁻13 - 6 = ⁻19
<u>When seeing this, we can see that the answer to the questions is A.</u>
