0 Guest Posted August 16, 2008 Report Share Posted August 16, 2008 This is a tough one. The closest answer I can find is .81 with a result of 18.164. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted August 16, 2008 Report Share Posted August 16, 2008 Quotient of what? Its square and its half? I think I got it. Using the formula y=(x^2/(x/2)+36)/2 When x=35, y=53 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted August 16, 2008 Report Share Posted August 16, 2008 Do you mean ((x^2/2)+36)/2=y I believe this has no answer or Do you mean ((x^2/(x/2))+36)/2=y 35 is the answer Quote Link to comment Share on other sites More sharing options...
0 Guest Posted August 17, 2008 Report Share Posted August 17, 2008 Quotient of what? Its square and its half? These are the steps you perform on the answers you get after each operation ... When you square it , half it, add 36 to the quotient and then divide it by 2 ..... The digits gets reversed ... What is the number ??? Means .... 1) Square the number i.e. x² 2) Half the product you got from step 1 .... and so on Quote Link to comment Share on other sites More sharing options...

Which two numbers here do you use? The squared number from step 1 and half of that number from step 2? Using this results in the following: ( x^2 / ( x^2 / 2) + 36 ) / 2 = y therefore y = 19 and although all the x's drop out of the equation, the reverse must be 91.

0 Guest Posted August 17, 2008 Report Share Posted August 17, 2008 "half it" means divide by 2, the result of halfing would be the quotient OHHHHHH! Makes all the sense in the world now! Apologies for the confusing mumbo-jumbo earlier. ( x^2 / 2 + 36 ) / 2 = y x^2 / 4 + 18 = y Clearly, for this to work, x^2 / 4 + 18 must be less than 100. This means that x is less than 19. x must also be greater than 9. 10,11,12,13,14,15,16,17,18 all don't work, so it is unsolvable this way, unless I made a mistake.

Quotient is the answer you get when you divide .... when you halve a number, you are dividing it by 2 Quote Link to comment Share on other sites More sharing options...
