If you assume that at the bottom left corner the coordinates are i = 0, j= 0. and at the other end (18,0).\nT has to be:\nT = 18/7.5\n\nFor Y coordinate, it must be zero:\n12t - 5t^2 = 0\nt = 0, or 12/5\n\nso 12/5 = 18/7.5 which is at the bottom right (18,0) and proves the question.

I think a calculator would be great for this one! It sounds perfect for a math wiz to try...Good luck! MayMay

[ (50000 x 2.4)+(25000 x .8) ] / (50000+250000)=1.8\n\nThe remainder of the info in the problem is not necessary.

Add them together and divide by 5.\n\nWow. I could seriously have you people do my homework for me. Every night. I'll type out the problems and see how you all do. :P JP

ignore the decimals when u originally do the problem, then however many deciams there are in both of the decimals you're multiplying is how many there will b in the answer. i.e. if you multiply 6.78x4.234 together the answer will have 5 numbers behidnthe dceimal point

a. 4.5 * 10^5\nb. 6.7 * 10^(-5)\n\nHope this helps for your homework now try to get some sleep if you don't have too much more!  Ha ... I should listen to my own advice ... I think I'm going to it is late ... kinda.  :)

Can you please check you haven't made a mistake somewhere? I have just calculated (with 99% certainty) that there are no solutions to those equations with those restrictions.\n\nEdit - OK, I assumed you made exactly one mistake. By removing each possible word and trying to solve it, I discovered that removing 'SIGH' was the only option that gave an answer.\nt 1\nh 8\na 3\nn 7\nk 6\ns 5\ng 9\ni 4\nv 2\nwhere SIGH = 26, not 25. Then THANKSGIVING = 65.\n\nThat was actually a cooler puzzle that the original, assuming you made one mistake :)
