The worlds first riddle!

1. all of them
2. numbers, 12 cents
3. (m)other and a boy
4. 2.1 lbs
5. 2*sqrt(10)
6. Cindy seeks psychologists.
7. Cindy cooks chicken.
8. 20 hours

[size=7]1) All of them 12 months have 28 days
2) House Nunbers-12 cents
3) 2b+g>F & 2g+b<M
the 2b+2g>F+g and 2b+2g<M+b
so F+g<M+b, so Mom and a boy beat Dad and a girl
4) 1 2/2 c=1 1/2# so 1c=1#
5) for the circumference to be entirely on black chessboard square it is on a single square. d=2"
6) Nancy Knows Pneumonia.
7) Greg Generates Gnus.
8) f=61*t s=58*t 61*t-58*t=3*t=60 so t=20--20 hours
9) 2350=2^3*3^2*5*7 and is a composite of the smallest prime numbers. As such it is an anti-prime. It has more factors than any smaller number. This behavior makes it a 'versatile' number
10) My old dogs? [/size]

I thank markr for the idea of answer camouflage.

Sorry guys! but I don't think that the circle has to be entirely on a single black square. The circumference can be shared by 4 black squares without there being any circumference on white squares. A white square would be in the center of the circle, but the circumf. itself lies on black at all times.
So......the diameter of the largest circle that can be drawn on the board in such a way that the circle's circumference is entirely on black squares is the square root of 2....or better known as the irrational #!
The diameter is:

1.4142135623 7309504880 1688724209 6980785696 7187537694 8073176679 7379907324 7846210703 8850387534 3276415727 3501384623 0912297024 9248360558 5073721264 4121497099 9358314132 2266592750 5592755799 9505011527 8206057147 0109559971 6059702745 3459686201 4728517418 6408891986 0955232923 0484308714 3214508397 6260362799 5251407989 6872533965 4633180882 9640620615 2583523950 5474575028 7759961729 8355752203 3753185701 1354374603 4084988471 6038689997 0699004815 0305440277 9031645424 7823068492 9369186215 8057846311 1596668713 0130156185 6898723723 5288509264 8612494977 1542183342 0428568606 0146824720 7714358548 7415565706 9677653720 2264854470 1585880162 0758474922 6572260020 8558446652 1458398893 9443709265 9180031138 8246468157 0826301005 9485870400 3186480342 1948972782 9064104507 2636881313 7398552561 1732204024 5091227700 2269411275 7362728049 5738108967 5040183698 6836845072 5799364729 0607629969 4138047565 4823728997 1803268024 7442062926 9124859052 1810044598 4215059112 0249441341 7285314781 0580360337 1077309182 8693147101 7111168391 6581726889 4197587165 8215212822 9518488472 08969

...And these are only the first 1000 decimal points!

One could argue that there isn't any black at four points in the circumference then. But if you can argue that, you can argue that there is no white either. As long as the corners of the black squares touch...then the circumference lies on black. and the circumf. is then 1.4142....etc

I miscalculated.....the irational # is the radius. The diameter is twice that value.....which is still a very long number...

Hmmm. I didn't constrain my circle to one black square.
2*sqrt(10) > 2*sqrt(2)

sorry...didn't read your invisi-type right....my bad!!!

circle radius ib the shessboard is sqrt(1^2+3^2)

dia is 2*10^(1/2)

Not as nice as hidden text elsewhere, but it serves the purpose.

No problem. Does your horse race puzzle friend have any more puzzles?

I know one about 12 coins..one of them being a fake and you have three goes on the balance scale to figure which is the fake. But it's not really up to par with you guys's riddles! You've probably done it before...but if not...there you go. (The scale is the old fashioned type...like in the zodiac...so no actual weight values are given). Also, you don't know if the fake weighs more or less.

That's a good one, but I did it years ago.

i've just finished

thanks.

The pain continues: Part II

11. Is it safe to write a letter on an empty stomach

12. Can you explain how long cows should be milked

13. What is the best thing to put into cakes

14. What kind of umbrella do most people carry on a rainy day

15. What always happens at the end of a dry spell

TWO COIN FLIPS
I flip a penny and a dime and hide the result from you, one of the coins came up heads.

What is the chance that the other coin also came up heads

[size=7]11. no - you'd have to penetrate you skin and abdominal muscles
12. the same as short cows
13. your teeth
14. open
15. precipitation
16. lift his foot
18. on the head
19. fence
20. roof

11. ?
12. ?
13. Marijuana!!!!......Uhhmm, I mean Candles!!
14. The Morning Paper
15. You get laid, or…It rains (It depends on your definition of "a dry spell")
16. ?
17. ????
18. On the head
19. Fence….going on the "freeway" rational so no credit here!
20. Shingles….same as above

Lastly…..the trick question! Answer is 50% …. Being that you uncovered one of the coins already!
It would be a 25% chance that both turned "heads" before you told us the outcome of one of them! I'm also foreign and don't know if both a dime and penny have a "head" side. But lets assume they both do.
