Suppose the toothpicks are arranged as follows (i.e. 3 per row; after all they are long and thin!):

Then you get 12 rows with 16 left over.

No I think it need new batteries

3)   This one has got Chris and me stumped.  Aditya has been desperate for an answer for about 24 hours. 

       Maybe some brilliant person can help her/him out.

Hi all,

We have had some great answers today from CPhill, Alan, Omi67, Hayley1, Kallomoar, geno3141, gibsonj338, Solveit, RinElys and Coldplay.  Thank you.   

Technical Issues:

How can you post a picture when the picture upload on the forum is not working properly ?

Thanks very much Alan for these instructions.

Hi Coldplay and CPhill,

Do you mean

Guten Morgen and Guten Nacht!   ?

Yea I'd like some carats of gold - that'd be good :)

I am listening to

Guten Morgen and Guten Noch!

Thanks! And you sure Melody, I sure could use some 15karat gold right about now! :)

6³   would be entered as    6^3

^ is a caret, sometimes it is called a hat.  In mathematics it is always understood to mean "to the power of"

That is caret with an e                  - not bug's carrot and not a golden carat.   Hahaha :)

Use the " ^ " key, should be located where "6" is

I'm getting confused. Don't contradict each other explain how the other was wrong. :)

ROFL! I am dying! :))))))

Try it with your famous formula: FV=PV(1+.08/12)^8=13,000(1.0066666666667)^8=13,000 X 1.05459=$13,709.73. ARE YOU HAPPY NOW, QUEEN BEE!!!!!.

It turns out that the '?' can be whatever we want it to be!

Allow me to illustrate. Take for example, f(x)=(1/40)x^4-(13/20)x^3+(291/40)x^2-(553/20)x+42, and evaluate f(8), f(7), f(6), f(5), f(3). It turns out that:

f(8)=56,
f(7)=42, 
f(6)=30, 
f(5)=20, 
f(3)=9.

Wait, what sorcery is this? Turns out that although the popular rule f(x)=x(x-1), which gives f(x)=6, satisfies the known values in the sequence, that f(x)=(1/40)x^4-(13/20)x^3+(291/40)x^2-(553/20)x+42 also satisfies them--except with a different value of f(3)!

Here's another one that also works but gives f(3)=12:
f(x)=(1/20)x^4-(13/10)x^3+(271/20)x^2-(543/10)x+84

And here is one where f(3)=π
f(x)=(1/120)(π-6)x^4-(13/60)(π-6)x^3+(1/120)(251π-1386)x^2+(1/60)(3138-533π)x+14(π-6)

Finally, in general if you want the '?'=k, i.e., f(3)=k where k is the value of your choice, then
(1/120)(k-6)x^4-(13/60)(k-6)x^3+(1/120)(251k-1386)x^2+(1/60)(3138-533k)x+14(k-6)

I think guest should take his/her multiple, multiple choice questions and go away.

Afterall, he/she could guess every one of them and still get approximately 20% of them correct.

(since there are 5 answers each)

I'm not sure, I don't know how to do it. I was hoping guest would explain so I could learn, Idk what the compound interest  is. :)

Yea, I don't think that the answer is B  ???

THE COMPOUND INTEREST IS OF COURSE: D

 :)You win, lol!

LET THEM TRY AND SEE IF THEY CAN GET THE SAME ANSWER!!!!.

The answer is: d

The answer is: A

 3 times 7 is 21

So the square root of 21 is 3 times 7. 

Oh 7 times 3 is also the answer

The answer is: d
