Bloodrun Posted August 24, 2008 Report Share Posted August 24, 2008 Pretty the title says it all.. I have some questions for you math wizards out thar..First question:How many children are there in a family wherein each girl has as many brothers as sisters, but each boy has twice as many sisters as brothers? o.0" toughy? lets see. next question: Which terms must be be removed from 1/2+1/4+1/6+1/8+1/10+1/12 if the sum of the remaining terms is to equal 1? o.0"" toughy? lets move on. next question: use inductive reaoning, to find the next term that should follow this sequence of numbers ;)1, 8, 27, 64, 125.... o.0""" toughy? reguires thought, lolalso, dont ask me for the answers, i dont know em >.< Link to comment Share on other sites More sharing options...
Silent Member Posted August 24, 2008 Report Share Posted August 24, 2008 The first one is three children. 1 Boy, 2 Girls. Link to comment Share on other sites More sharing options...
Umbra Posted August 24, 2008 Report Share Posted August 24, 2008 1st: Five. Three girls and two boys. 2nd: 1/8 and 1/10 should be removed. 3rd:1=1^48=2^327=3^364=4^4125=5^3196=6^3So, my guess is for 196. Link to comment Share on other sites More sharing options...

Umbra Posted August 24, 2008 Report Share Posted August 24, 2008 Must've miscalculated on the the fourth. (And the first was a mere guess.) Link to comment Share on other sites More sharing options...

Deucalion Posted August 25, 2008 Report Share Posted August 25, 2008 First question is a simultaneous equation. The first statement is b = g-1, where b = boys, and g = girls. The second statement is g = 2b-1. [statement 1]b = g-1[statement 2]g = 2b-1 [-b] 0 = g-b-1[x2] 0 = 2g-2b-2[+ statement 2] g = 2g-3[-g] 0 = g-3[+3] 3 = g So, there are three girls. Now we can adapt statement 1 accordingly. [statement 1]b = g-1b = 3-1[=]b = 2 There are three girls and two boys. Next question. 1/2+1/4+1/6+1/8+1/10+1/12 Convert the base terms, to make it: 60/120 + 30/120 + 20/120 + 15/120 + 12/120 + 10/120 The total of that is: 147/120. We need 120/120, so we need to lose 27/120. 15/120 + 12/120 = 27/120, so 15/120 and 12/120 need to be removed, and they are 1/8 and 1/10. Next question. 1, 8, 27, 64, 125 --7-19-37-611, 8, 27, 64, 125 ---12-18-24--7-19-37-611, 8, 27, 64, 125 -----6-6-6----12-18-24--7-19-37-611, 8, 27, 64, 125 Sub in to the formula. 6 isn't in the baseline, so you halve it, leaving 3. There are no other numeral changes, making the term n^3. As an example. 1^3=12^3=83^3=274^3=645^3=125 Which fits perfectly. There, the 6th term in a n^3 equation is 6^3 = 216. 216 is the 6th term of n. That was easy. EDIT: For bonus prizes, Umbra, 64=4^4 is incorrect. 4^4=256. Also, Mariojo2, the square root of Pi is an impossible question - since Pi never ends, or at least, we don't know what it's end is, we can't discover it's square root. However, to the nearest 5 decimal places, the sqrt of Pi is 1.77245. Link to comment Share on other sites More sharing options...

CrabHelmet Posted August 26, 2008 Report Share Posted August 26, 2008 i thought there was a rule agenced fail pics I think a rule might have been made after fail pics became a fad...but as they are no longer a fad' date=' one fail pic isn't going to destroy the board. First question is a simultaneous equation. The first statement is b = g-1, where b = boys, and g = girls. The second statement is g = 2b-1. [statement 1]b = g-1[statement 2]g = 2b-1 [-b] 0 = g-b-1[x2] 0 = 2g-2b-2[+ statement 2] g = 2g-3[-g] 0 = g-3[+3] 3 = g So, there are three girls. Now we can adapt statement 1 accordingly. [statement 1]b = g-1b = 3-1[=]b = 2 There are three girls and two boys. Wrong. Statement 2 says g = 2(b-1), not g = 2b-1. There are actually three boys and four girls.
