Problems and SolutionsIn this topic, I shall give a problem and give the (proper mathematical) solution after a week. Character is who you are when no one is looking. #3 20050715 15:10:52
Re: Problems and SolutionsOutstanding! You are really supersmart! Character is who you are when no one is looking. #4 20050715 17:20:51
Re: Problems and SolutionsWork out how much milk there is, then make an equation. Why did the vector cross the road? It wanted to be normal. #5 20050715 17:49:21
Re: Problems and SolutionsLOL ... I think about 3 seconds of that would be enough! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20050715 21:02:55
Re: Problems and SolutionsThat is close to a 1,000 gallons! Character is who you are when no one is looking. #7 20050716 02:55:31
Re: Problems and SolutionsI think you would have to add 5 liters of water to make it 20% #8 20050716 03:11:18
Re: Problems and SolutionsThat's what I got too. Why did the vector cross the road? It wanted to be normal. #9 20050716 20:43:33
Re: Problems and SolutionsThats right! Character is who you are when no one is looking. #10 20050716 21:46:26
Re: Problems and SolutionsOh, silly me. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #11 20050716 21:53:42
Re: Problems and SolutionsI seem to recall that there was a puzzle where there was a lake that contained too much salt. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #12 20050716 21:57:11
Re: Problems and Solutions
I think that still applies. It's an interesting puzzle though, I might just have to do that one. Why did the vector cross the road? It wanted to be normal. #13 20050716 22:06:12
Re: Problems and SolutionsI shall try to solve that when I start the next week, Character is who you are when no one is looking. #14 20050716 22:09:12
Re: Problems and SolutionsI've seen it before, and it is HORRIBLE. Why did the vector cross the road? It wanted to be normal. #15 20050716 22:24:18
Re: Problems and SolutionsI saw this problem and I was impressed. I didn't know someone had posted a similiar problem earlier. Okay, I shall give the solution and post a new problem instead. Character is who you are when no one is looking. #16 20050716 22:50:08
Re: Problems and SolutionsHmmm ... you write 9 once every 10 numbers ... "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #17 20050716 23:00:54
Re: Problems and SolutionsMy guess Why did the vector cross the road? It wanted to be normal. #18 20050718 15:17:01
Re: Problems and SolutionsYou are right, Mathsy! Character is who you are when no one is looking. #19 20050718 16:08:09
Re: Problems and SolutionsHmm. It's not too hard to solve, but I could never do it with those limitations, so I fail. Why did the vector cross the road? It wanted to be normal. #20 20050718 17:16:07
Re: Problems and SolutionsDammit! I had the answer to the nines one, but then I forgot it again!!!! School is practice for the future. Practice makes perfect. But  nobody's perfect, so why practice? #21 20050718 17:22:00
Re: Problems and SolutionsThe Lake Problem. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #22 20050718 18:16:17
Re: Problems and SolutionsI um unable to reply. I shall wait for your post and comment on that later, MathsIsFun.
Since both the ratios have 4 or a multiple of 4 for C, Character is who you are when no one is looking. #23 20050719 14:52:38
Re: Problems and SolutionsA cistern can be filled by two pipes A and B separately in 45 minutes and 36 minutes respectively. A tap C at the bottom can empty the cistern in 30 minutes. If the tap C is opened 7 minutes after the two pipes A and B are opened, in how many minutes will the cistern be full? Character is who you are when no one is looking. #24 20050719 17:25:00
Re: Problems and SolutionsWhy did the vector cross the road? It wanted to be normal. #25 20050719 18:14:08
Re: Problems and SolutionsYou got it √ Character is who you are when no one is looking.
