Re: Oral puzzles416. A ladder leans against a vertical wall. The top of the ladder is 8 m above the ground. When the bottom of the ladder is moved 2 m farther away from the wall, the top of the ladder rests against the foot of the wall. What is the length of the ladder? Character is who you are when no one is looking. #178 20060701 14:55:42
Re: Oral puzzles421. The probability of getting a prime number from a number chosen at randon from 1 to 20 is __________. Character is who you are when no one is looking. #179 20060708 09:28:18
Re: Oral puzzles421) 8 out of 20 or twofifths or 40%. ( 1 is not prime according to one source I read) igloo myrtilles fourmis #180 20060708 10:02:05
Re: Oral puzzles
A prime number is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself. #181 20060709 04:53:10
Re: Oral puzzles424. If cos θ =12/13, find (cosecθ tanθ + sinθ cosecθ). 425. a ladder makes an angle 60° with the floor and its lower end is 4 m from the wall. Find the length of the ladder. x.cos60 = 4, cos60 = 0.5, x = 4/0.5 = 8 The Beginning Of All Things To End. The End Of All Things To Come. #182 20061009 19:21:09
Re: Oral puzzlesWoah. Octadecuple posting. It'd look a lot nicer if you just edited your existing latest post whenever you thought of a new answer, instead of just making a new post for it. Chains of 2 or 3 posts of answers are alright, but 18 is a bit much. Why did the vector cross the road? It wanted to be normal. #183 20061009 19:23:27#184 20061009 19:27:40

Re: Oral puzzlesI'm going to change my answer for 117, and say 48 instead of 64. #186 20061014 03:28:02#187 20061014 03:38:16
Re: Oral puzzleswhy change your answer? after all, with the way your brain works, your first instinct/inclination is normally correct unless you are revising an error... #188 20061014 03:41:15
Re: Oral puzzlesThat simply is not true. And I can change my answers whenever I wish, thank you. #189 20061014 03:43:52
Re: Oral puzzlesdude, chill! maybe if you spent more time with real people that aren't online, then you would be able to see that being rude and a total egomaniac aren't going to get you anywhere socially...and btwe, you're welcome! #190 20061014 03:52:48
Re: Oral puzzlesHolla, what is it about Devanté that makes you feel the need to flame everything he says? Why did the vector cross the road? It wanted to be normal. #191 20061015 11:04:34#192 20061104 06:29:45

Re: Oral puzzlesMe and pi man are both awesome at answering that question. Why did the vector cross the road? It wanted to be normal. #194 20061106 05:24:18#195 20070226 18:20:19

Re: Oral puzzlesThat one is remarkably simpler! Character is who you are when no one is looking. #199 20070228 01:57:46
Re: Oral puzzlesYes, I fell into that trap as well. I diligently worked out what the two numbers needed to be, and it was only when I got to adding their reciprocals that I realised that I needn't have. Very nice, sneaky puzzle.
