Math Nerds help me solve this Math Problem

Okay…so if I know the rate at which water drips from a bathtub faucet, how do I calculate how long it will take to fill the bathtub?

Suppose the water drips at a rate of 1 liter per minute, and the bathtub is 1 liter. How long will it take to fill the tub?

Now suppose the rate is 10 liters per minute, bathtub 10 liters. Now how long?

1 liter/min, 10 liter bathtub?

10 liter/min, 1 liter bathtub?

Is there a pattern? Can you write down a formula to describe the pattern? Can you use the formula to answer your question?

no…anyway, i dont know how many liters the tub is, i just know it is 8 ft by 12 ft.

8x12… (you need depth for volume as well)

there is no bottom, so it will never be filled

-Imp

the bottom is 3 ft

8x12x3 is the volume in cubic feet

divide the volume by the amount dripping to find the time

-Imp

If it takes fourteen Irishmen 7.3 minutes to get out of the back of a Ford Escort and into a telephone box then what is the exchange rate between bottles of milk and pyramids?

the din of ducks is deafening

-Imp

are you sure?

that’s how I’d have done it

-Imp

(volume) /[volume/time] = volume * time / volume

volume and volume cancel, yer left with time… now plug and chug…

This makes me wonder: what would you have to offer Egypt for them to give you a pyramid? Suppose we develop fusion reactors as a clean, reliable, effectively infinite source of energy. Then we deny Egypt the knowledge/use of it, unless they give us a pyramid. Would they give it to us? And assuming we find a way to transport it, where do we put it? Las Vegas?

Depending on the exchange rate, and the mass of the Irishmen, I’m thinking somewhere between 14,000 and 54 million bottles of milk. Or the Parthenon.

Then we could automate the construction of our own pyramid and sit back and watch, like in Rise of Nations.

It’s probably be quicker and easier to just invade them. Again, as in Rise of Nations.

How hard can it be? Once we’ve got the space elevator network in place, moving gigantic ancient monuments will become commonplace. Soon, every moderately wealthy family’s garden will look like the set on an Indiana Jones movie.

Well, anywhere with a desert and available flow of tourists, so yes, Vegas.

with nazis as lawn jockeys?

huh?

Sounds to me like you are having trouble getting an intuitive idea of what is going on in this problem. Let’s try a simpler problem. Say a bug is crawling up a pole at R inches/second. The pole is L inches tall. How long will it take the bug to reach the top? (call this time T.)

If you have trouble with this, start with simple numbers in place of R and L: what happens to T when

  1. R = 1, L = 1
  2. R = 10, L = 10
  3. R = 100, L = 100
  4. R = 10, L = 1
  5. R = 1, L = 10.

Here’s another approach. Suppose for a certain pole length L and bug speed R, it takes the bug T = 10 seconds to get to the top. How long does it take if we double the bug’s speed? Half its speed? And what happens when we double or half the pole length? If you answer these questions you should see a pattern that allows you to deduce a formula for the time T, in terms of L and R. Once you figure this one out you may be able to tackle the original problem.

okay i have another one i need help with:

okay how would you solve a problem wher you know how much money you have to spend for a building and then you have to determine how big the building can be based on the money you have and then you need to graph it…

Also, would the graph be a staright graph or a parabola or neither???

HEEEEEEEEELLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPPPPPP!!!

What’s the question?

its like, you have 54,000 and a square foot of building material costs $5 so then how big can your building be and then graph it.
