Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
Answer:
4/3
Step-by-step explanation:
Using the formula of rise/run:
9-1 = 8
8-2 = 6
8/6 =4/3
Answer:
-9 1/4
Step-by-step explanation:
To determine the number of tickets that Ric sold, subtract from the total tickets sold the sum of the number of tickets sold by Alex and Ian. This is mathematically shown as,
tickets (Ric) = tickets (total) - (tickets (Alex) + tickets (Ian))
tickets (Ric) = 48 - (11 + 18) = 19
Hence, Ric sold 19 tickets for the fundraising.
It typically just needs two parts
1) all parties must be in agreement
2) something of value needs to be exchanged. ie. money, a service
