Re: 10 second questionsExcellent, kylekatarn! Character is who you are when no one is looking. #153 20070204 21:27:55
Re: 10 second questions
Wow... that's amazing! Is there a reason why logging it will give you the number of digits? #154 20070204 22:45:45
Re: 10 second questionsYep. I made a mistake there, it should actually be 500*log 2, rounded up. But with the correction, it works. Why did the vector cross the road? It wanted to be normal. #155 20070204 23:54:18
Re: 10 second questions
Thanks, its good to be back : ) #156 20070205 15:20:00
Re: 10 second questions86. How many distinct prime factors does 2400 have? Character is who you are when no one is looking. #157 20070206 00:39:59
Re: 10 second questions86. Three: 2, 3, 5. Why did the vector cross the road? It wanted to be normal. #158 20070206 00:41:06

Re: 10 second questions89. (1 and a bit) + (1 and a big bit) + 2 + (2 and a little bit) = ~7? Why did the vector cross the road? It wanted to be normal. #161 20070206 04:04:11
Re: 10 second questions89. √2 + √3 + √4 + √5 ≈ 7 #162 20070207 01:01:57
Re: 10 second questionsWell done, mathsyperson and Devante`. Character is who you are when no one is looking. #163 20070207 01:15:50#164 20070207 02:14:51
Re: 10 second questionsWelcome to the forum, Maelwys! Incidentally, I read somewhere ages ago that the number of feet in a mile is closely approximated by . Completely useless, but still fun. Why did the vector cross the road? It wanted to be normal. #165 20070208 15:30:04
Re: 10 second questionsI agree with mathsyperson. But I shouldn't have posted this question in the 10 seconds section. I am sure that would never have been enough. Character is who you are when no one is looking. #166 20070209 15:19:02
Re: 10 second questions94. Can you think of a triangle whose angles are in Arithmetic Progression? Character is who you are when no one is looking. #167 20070209 17:09:00#168 20070210 00:24:06
Re: 10 second questionsThere are actually lots of triangles that would work for 94. Equilaterals are another example. The only condition you need is that one of the angles is 60^{o}, if that's true then the other angles will always fit. Why did the vector cross the road? It wanted to be normal. #169 20070210 15:38:03
Re: 10 second questionsYes, both Toast and mathsyperson are correct! Good work! Character is who you are when no one is looking. #170 20070210 16:02:49
Re: 10 second questions99. If Sn denotes the sum of n terms of an Arithmetic Progression and S1:S4 = 1:10, then what is the ratio of the first term to the fourth term? Character is who you are when no one is looking. #171 20070210 22:00:48
