Hey man, I'm just the messenger for most of those. Please don't hurt me.

If you can prove it wrong, I'll bump you 15 points right then and there. https://forums.windrivers.com/images.../2005/03/1.gif

(2+2+2+2+2)/2=5

That seems too easy...

Edit: Here's another way it can be done...

2+2+2/2=5

That's all very nice, but the question requires the use of only two 2's...


Should I keep posting questions even though this one is still open?

Oops... I guess it would help to read and pay attention to the entire question...

The NyQuil I took last night and the DayQuil I took this morning have me feeling a bit spaced out right now... :cool:

Here's a cheap way of doing it, but how about this...

(x+x+x+x+x)/y = 5

where x = 2 and y = 2.

:thumbs2:

That's ingenious, but I can't accept it. https://forums.windrivers.com/images.../2005/03/1.gif


Time's up for me today. :(

3 to the third power - 22 = 5

or

3 squared - 2 squared = 5 (but would you count the squared as more 2s?)

If I remember correctly it is:

SQRT(.2 ^ -2)
take .2 and raise it to the power of -2 and take the square root which should =5 if I still remember how to do this correctly.

X/X + 2 + 2 = 5

So that's 3 pts per day x 2 = 6 points total. :D

In any case, that was worth double in my book.

And you're official title shall henceforth be "Math King" in this game. https://forums.windrivers.com/images.../2005/03/1.gif

Since you previously told me we didn't know where the wires were underneath the carpet, and that they ran parallel....

Now I will further claim that you then cannot know which direction they run, since they cannot be seen.

Knowing this, there is only a 50% chance that the answer given as correct would work. If the wires were running in the same direction as the boards, then all the weight from one board would be on one wire, instead of several. This would set off the alarm. Do I get 15 points now ? :devil:

Another alternate answer would be to cut the 2x4 longways, this would make 2 1x4's 5 meters long which would distibute the weight even more.

All right!

OK!!

The 15 pts was for conclusively proving that the answer could not be from a mathematical point of view.

I can only grant you half of that: 7.5. :D

And the gap lessens... :devil:

Imagine two bridges that are exactly alike except that every dimension of one bridge is twice as large as the other. For example, the larger bridge is exactly two times longer, its structural members are exactly two times thicker, and so forth.

Which of the two bridges would be stronger, or is their strength the same?


__________
The one twice as large will be weaker. The larger bridge is more prone of collapsing under its own weight.
