Answer:
600 minutes or 10 hours
Step-by-step explanation:
We can solve this problem by looking at the net increase per minute. To find this, we can set rates for each value.
The pipe will be able to fill 1/120 of the tank in a minute, and the drain will drain 1/150 in a minute. So subtract the two:
1/120 - 1/150 = 1/600 of the tank per minute
Therefore you need 600 minutes to fill the tank, or 10 hours.
Answer:
4x^2 + 4x + 3.
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 5x^2 - 3 - (x^2 - 4x - 6)
= 5x^2 - 3 - x^2 + 4x + 6
= 4x^2 + 4x + 3.
2 y
6x+y=4 x= _ - _
3 6
x-4y=19 x=19+4y
Let's use our largest amount (quarter) to see how many can fit evenly into 1.74.
- 1.74/0.25 = 6.96
- The most quarters that can fit into $1.74 is 6.
---Multiply $0.25 by 6 = $1.50
---Subtract $1.50 from $1.74 = $0.24
---We need to use the rest of the coins to fill up $0.24.
Now let's use our second largest amount (dime) to see how many can fit evenly into 0.24.
- 0.24/0.10 = 2.4
- The most dimes that can fit into $0.24 is 2.
---Multiply $0.10 by 2 = $0.20
---Subtract $0.20 from $0.24 = $0.04
No nickels can fit into $0.04, because they are worth $0.05.
We can use our least amount (pennies) to fill in the $0.04 remaining.
Your answer is 6 quarters, 2 dimes, and 4 pennies.
The answer is 20
Reason: so the W is 4 and the L is 6 so you do 4+4=8 then you do 6+6=12 then you add the two together and get 20
