Answer:
48/b
Step-by-step explanation:
32÷16=2 so it takes two minutes per airplane. if she makes airplanes for 96 minutes at the same pace (2 min per airplane) then you need to divide 96 by 2 which gives you 48!
3% means 1.03 per year
multiplier 1.03
After 30 years
400 x[ (1.03) 30 times] = $970.91
Answer:
f(4) = 11
Step-by-step explanation:
To evaluate f(4) substitute x = 4 into f(x)
f(4) = 3(4) - 1 = 12 - 1 = 11
Answer:
B
Step-by-step explanation:
According to the information given, the system of inequalities that models the situation is given by:
<h3>System of inequalities:</h3>
For the system, the variables are:
- x is the number of hours that Pump 1 runs.
- y is the number of hours that Pump 2 runs.
They will run for at least 18 hours in a day but obviously no more than 24 hours in a day, hence:


Pump 1 can move 120 gallons per hour while Pump 2 can move 200 gallons per hour. In total the two pumps must move at least 3,000 gallons of water per day, hence:
