|#3 - Posted by: _237th_SC_Com_Bly (Member) on 12-27-2008 at 08:02|
oh wait now i see it must be 59 minuets but i voted 30 damm
|#4 - Posted by: froggy14 (Member) on 12-27-2008 at 08:27|
Yeah it is 59, because at 59 minutes it is half full, then it doubles in one miute so it is full.

lol, I JUST had this question in a math class about a month ago....how ironic.
|#6 - Posted by: attackmike (Member) on 12-27-2008 at 09:39|
NOOOOOOOOOOOOOOO MORE MATH 59 but noooooo
|#7 - Posted by: Enceladus1 (Staff) on 12-27-2008 at 09:46|

|#11 - Posted by: negah (Member) on 12-27-2008 at 12:40|
best poll eva
wish its not the last of such kind
|#12 - not 59 - Posted by: Corran_132 (Member) on 12-27-2008 at 12:47|
actually, that's not right
If it said the amount of water in the tank doubles every minuite, then you are correct
however, it say that the rate of flow of water into the tank doubles, NOt the total ammount of water. So (for example), if 1L of water flows into the tank minuite 1, 2L of water flows into the tank minuite 2. However, 1L of water is still in the tank from minuite 1, thus the water in the tanks is 3L.
So you people who said 59 are wrong
|#13 - actually... - Posted by: Corran_132 (Member) on 12-27-2008 at 12:56|
sorry, just calculated it. You were right.
|#14 - Posted by: Star_Wars_Pro93 (Member) on 12-27-2008 at 16:52|
that is a TOUGH one! I'm only on 9th grade :(
|#15 - Posted by: empor_garr (Member) on 12-27-2008 at 18:09|
wth why are u asking a ? like that
|#16 - Posted by: Vaders_legion (Member) on 12-27-2008 at 19:58|
It never was half full, the tank happened to accumulate too much air pressure and blew before it ever made it to that point of being half empty :P.
|#17 - Posted by: Bubbleteatroopa2 (Member) on 12-27-2008 at 20:56|
aww that tricked me -_-:confused:
|#18 - Posted by: AdmiralSnackbar (Member) on 12-28-2008 at 11:39|
my brain broke from thinking to hard:p lol
|#19 - Hmm.. might be a trick question - Posted by: GrdAdmSenza (Member) on 12-28-2008 at 12:06|
59 minutes i guess, i still think it might be a trick question, but i cant be sure.
|#20 - Posted by: the_pessimist (Member) on 12-28-2008 at 16:17|
the tank is half full when Emperor Palpatine says it is!
|#21 - No Fair - Posted by: ZebulaNebula (Member) on 12-28-2008 at 20:07|
This is a weekly poll, not a weekly puzzle.
|#22 - Posted by: Commander_Fordo (Member) on 12-29-2008 at 08:23|
Lol, it is half full in 30 minutes, because it get full in 60 :D
The capacity of the tank was NOT mentioned in the text, so we DO NOT have to calculate the liters!!! :p :D
|#23 - homework - Posted by: the_stag (Member) on 12-29-2008 at 08:39|
Thanks for asking us to help us with your homework
|#24 - Posted by: CaptainVerbic (Member) on 12-29-2008 at 12:56|
What tank is the water flowing to? A Tiger, M4 Sherman or maybe T-70?
|#25 - Posted by: froggy14 (Member) on 12-29-2008 at 17:15|
Commander_Fordo, you havent realized it is a trick question yet...have you not read all of the comments...
|#26 - Never Was - Posted by: Massive_Killer (Member) on 12-29-2008 at 19:43|
It never was half full because I destroyed it with arty spam.
|#27 - Interesting... - Posted by: hairbautt (Member) on 12-30-2008 at 11:34|
Nice one. :borg:
|#28 - @ Fordo - Posted by: InvisibleHand (Member) on 12-30-2008 at 15:16|
Yeah Fordo, it doesn't matter which capacity the tank has.
Oh and this is TOO random..
|#29 - Posted by: Corbec_UST (Member) on 12-30-2008 at 21:05|
Wow, this one took me a bit but I got it
59 ... "All to easy"
unless Im wrong
|#30 - Posted by: bobthe (Member) on 12-31-2008 at 14:45|
:confused:???What does this have to do with anything???:confused:
|#31 - Posted by: xpwolf (Member) on 01-01-2009 at 02:56|
Can anyone show how they found their answear?
Please include the full formula and all steps in the process.. because all my attempts to get an answear of 59.. fail.
|#32 - Posted by: froggy14 (Member) on 01-01-2009 at 07:36|
xpwolf, that's because it is 59...duh. No matter how big the tank is, if the amount of water doubles every minute and 1/2 X 2= 1 then it only takes a minute for it to double so if it was full at 60 min then it was half full at 59.
|#33 - Posted by: Jesse_Lee (Member) on 01-01-2009 at 16:55|
Talk about random...
|#34 - Poorly Worded - Posted by: Qui0jinn (Member) on 01-01-2009 at 21:06|
The question is Poorly worded, If you had Said "The Amount of Water in the tank doubles every minute" then 59 would be correct, however since it states "The Amount of water flowing into the tank double every minute" there is not enough information to determine the answer (however I know what you meant).
|#35 - ah - Posted by: mrunclesneakybob85 (Member) on 01-02-2009 at 16:33|
i don't know i think i put 15 before i thought about it
|#36 - @ froggy 14 - Posted by: xpwolf (Member) on 01-03-2009 at 00:52|
But, as just mentioned, the amount of water in the tank does NOT double, the RATE OF FLOW doubles every minute.
|#37 - Posted by: froggy14 (Member) on 01-03-2009 at 11:10|
Yes but because there is not an option that says "there is not enough info to determine the answer" then you must assume that is what they meant. You would have to know how big the tank is to determine it that way. Besides just google the question and you will find several sites with 59 as the answer.
