The local zoo is filling two water tanks for the elephant exhibit. One water tank contains 34 gal of water and is filled at a constant rate of 4 gal/h. The second water tank contains 30 gal of water and is filled at a constant rate of 2 gal/h. Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank. What are the constraints on the system?

Question

amistre64 · Answer

y = 4x , and y = 2x  since x is a natural variable to choose for "h"ours ....

amistre64 · Answer

the constraints tho ... i dunno what thats actually asking for

anonymous · Answer

A. both x0, y0 	
	B. x0 only 	
	C. y0 only 	
	D. There are no constraints on the system.

amistre64 · Answer

well, we dont want to go over and waste water id assume so we would have to have a constraint on how long to run the water (xo), which implies a constraint on how much water you can get (yo).

if i were to take a guess, I would say A; but thats only a guess.

Which ordered pair is a solution of the inequality?
y>=4x - 5

amistre64 · Answer

im sure your given options with that, so just plug in the values to see which one fits.

i dont really know this kind of stuff

amistre64 · Answer

its simple if you can add and multiply .... the notation might be whats wierd tho

amistre64 · Answer

an ordered pair is formed from x and y values and are displayed as (x,y)

the number on the left is your x value; the number on the right is your y value.

plug in each ordered pair one at a time into the "equation" and see if the results make sense or not

@RYSSA2K10, it is more appropriate to post only one question per thread.
