The Riddle of the Sphinx

[soccerates]

$500 to the one who can correctly answer the riddle of the Sphinx:

"What is it that has one voice and yet becomes four-footed and two-footed and three-footed?"

[soccerates]

Omar :Omar: (which is why he is Zeus around these parts) has already guessed it correctly in PM, but since no answer here on the forum, the $500.00 is still up for grabs ;)

[_GrimReaper]

this is an old one
the human

[soccerates]

this is an old one
the human

You're right...it's not very complex...

But why? Explain and the $500.00 bones are yours!

[penguin_007]

4-footed=the baby crawls around because he cannot walk

2 footed=adult human walk around on two legs

3-footed=old man walking with a cane.

heh, i knew it since i was grade 2.

[_GrimReaper]

ufff
as a baby he walks on 4 feet then - grown up 2 legs and at the and 2 legs+ a stick =3 legs...........

[soccerates]

Ok done...you get the 500 bones Grim...

[_GrimReaper]

should i tell you the nmber of mu bank account :D :D :D

Well for the single women; perhaps a pregnancy test kit :lol:

[_GrimReaper]

hehe good one
but NO

[Mexi]

a couffin (sp?)

[philipas]

:)

ok another one
What do you buy but never want to use? a coffin?

I've got one. It's not very difficult, but it surprises me how many people can't work it out.

A man is walking on a Mediterranean beach and sees a small casket poking out of the sand. He digs and gets the casket out and opens it to find it full of coins. He thinks they are current currency, but inspects the coins closely and sees that they are dated 100 BC. All excited in thinking he made an archaeological discovery, he takes them to the experts who quickly dismiss them as fake. Why are they fake?

[Mexi]

u got me. what's the answer?

[philipas]

u got me. what's the answer? Think about it. you'll get it...

[Mexi]

naw i think i've heard it b4 but i never got it. does it have to do w/ the 100 BC info? i guess i'll think about it till tomorrow then.

[RaulMadrid7]

Think about it. you'll get it...

I tought about it for a very long while and somehow i can't get myself to the right answer can you tell us the right answer I'm getting restless. :D

[wolverine]

naw i think i've heard it b4 but i never got it. does it have to do w/ the 100 BC info? i guess i'll think about it till tomorrow then.

I guess it's cos there were no coins during 100 BC.

[philipas]

I guess it's cos there were no coins during 100 BC. No, coinage was around well before that. C'mon guys, I got this in grade 5 and earnt an early recess for it. It's not that hard.

[RaulMadrid7]

I guess it's cos there were no coins during 100 BC.
actually there were coins in 100 bc, so you're wrong...
http://images.google.ca/images?q=100+bc+coins&svnum=10&hl=en&lr=


but Philipas what's the answer?

[RaulMadrid7]

OHHHHHH I THINK I GOT IT!!!!

Why would the people in 100 BC write 100 BC on their coins? :lol:

I HOPE THAT i GOT TEH RIGHT ANSWER?

[RaulMadrid7]

And to add to my answer, I don't think people in 100 BC would know that they were living before Christ was born. :lol:

You're right Philipas it was an easy but confusing answer.

[philipas]

And to add to my answer, I don't think people in 100 BC would know that they were living before Christ was born. :lol:

You're right Philipas it was an easy but confusing answer. Exactly..well done :thumbsup:

[RaulMadrid7]

Exactly..well done :thumbsup:

Yeah thanks. :D

Give me another one I need to warm up my brain for school. :D

[philipas]

Yeah thanks. :D

Give me another one I need to warm up my brain for school. :D OK.

1.What goes around the world, but stays in a corner?

2. You throw away the outside and cook the inside. Then you eat the outside and throw away the inside. What did you eat?

3. Give me food, and I will live; give me water, and I will die. What am I?

[philipas]

Anyway, have to go. See if you can answer these by tonight!!!

[_GrimReaper]

Clue:There can be more than one answer for the second one...

[nachi88]

ok->

what is the remainderere if (2222^5555 + 5555^2222)/ 7 ?

and why?

[philipas]

More brain teasers:

1. What is it that, after you take away the whole, some still remains?

2. Until I am measured, I am not known. Yet how you miss me, when I have flown! What am I?

3. I give you a group of three. One is sitting down and will never get up. The second eats as much as is given to him, yet is always hungry. The third goes away and never returns. What are they?


Think outside the square, as they say... :D

Repost them all and offer some CA$H for the correct answers, ya cheapskate ;)

[philipas]

Repost them all and offer some CA$H for the correct answers, ya cheapskate ;) OK, I offer a souvlaki in Melbourne, if anyone gets them right. Or I can send it by mail :D

I guess everyone can see who's the more generous of us two ;)

[_GrimReaper]

1. What is it that, after you take away the whole, some still remains?

the HOLE

give a clue for tha 3rd

[_GrimReaper]

22225555 + 55552222 = 35555 + 42222 (mod 7). There are only 7 residue classes modulo 7. Therefore, the series of powers of a given number (modulo 7) is bound to be cyclic (of period 6). For example, 32 = 2 (mod 7), 33 = 6 (mod 7), 34 = 4 (mod 7), 35 = 5 (mod 7), 36 = 1 (mod 7), 37 = 3 (mod 7), and so on: 3,2,6,4,5,1,3,... Note that 5555 = 5 (mod 6). Therefore, 22225555 = 35 (mod 7) = 5(mod 7).

Similarly, 55552222 = 42222 (mod 7). Powers of 4 modulo 7 form a cycle of period 3: 4,2,1,4,... Hence, 42222 (mod 7) = 42222 ( mod 3)(mod 7) = 42 (mod 7) = 2 (mod 7).

Adding up 5 + 2 gives a number divisible by 7. So is 22225555 + 55552222.

you are close... but you did not follow the question correctly

the question is (2222^5555 + 5555^2222)/ 7

^ -> means to the power of.
eg 6^3 = 216.

But you are on the right track. If youe xplain properly, the 500 points are yours.

[_GrimReaper]

Here's another one
Who killed 1/4 of the humanity??????

[_GrimReaper]

I just forgot th e ^

[nachi88]

can you explain your answer please. I am not sure i followed. But it seems u won the 500 points.

Another one............easier than above one

sum up the following---->

1 + 1/2 +1/3 + 1/4 + 1/5 + 1/6 + 1/7 + 1/8 + 1/9 +......................so on

Hmmm... looks familiar... from my 10th grade math class, when I wasn't skipping classes playin' my guitar down by the creek, someone mentioned somethin' about the infinite sum of 1/n for all n from 1 to infinity... a so called "harmonic series"... named as such no doubt for its application to the musical tones produced by the harmonics of a vibrating string.

http://cnx.rice.edu/content/m11118/latest/harmseries2.png

For the series 1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 + 1/8 + 1/9 + ....
we can group each number in the series by 1, 2, 4, 8... terms, after the 1 (fundamental) to get:
(1/2) + (1/3 + 1/4) + (1/5 + 1/6 + 1/7 + 1/8) + ....

Now, 1/3 + 1/4 is greater than 1/2... coz 1/3 + 1/4 > 1/4 + 1/4 (=1/2)
For the same reason, so too is 1/5 + 1/6 + 1/7 + 1/8
As is 1/9 + 1/10 + 1/11 + 1/12 + 1/13 + 1/14 + 1/15 + 1/16
so the answer is greater than 1 + 1/2 + 1/2 + 1/2 + ....
which obviously is unbounded (infinity)
that is, the sum :
1 + 1/2 +1/3 + 1/4 + 1/5 + 1/6 + 1/7 + 1/8 + 1/9 + ...
= 1 + (1/2) + (1/3 + 1/4) + (1/5 + 1/6 + 1/7 + 1/8) + (1/9 + ...
> 1 + 1/2 + 1/2 + 1/2 + ....
so the answer is infinity.

so the answer is infinity.

well done phillipas well done...

another one->( they will get tougher as you solve them)

you are given rectangle of boundary length 80 m. what should be its sides for maximum area included?

this one is comparatively easy.

[_GrimReaper]

x+y=80/2
x.y=S

so y=40 - x

(40-x)x=S

i dont know how its in english but you find the biggest X there can be

40x - x^2
40-2x=0
2x=40
x=20

20+y=40
y=20

!!!

[nachi88]

x+y=80/2
x.y=S

so y=40 - x

(40-x)x=S

i dont know how its in english but you find the biggest X there can be

40x - x^2
40-2x=0
2x=40
x=20

20+y=40
y=20

!!!

correct answer dude, again for maximum included area, it has to be a square of all 4 sided figures.

another one for you ( toughness increases)

you are standing on a cliff of 100 meters, and you have an artillery.Your enemy is down the cliff facing you, but far away. How much angle should you fire it, so it goes the maximum distance? ( the artillery can be moved from 0 - 90 degrees)

[_GrimReaper]

the answer is 45 i had to solve such a problem in school in 10th grade i dont think i can explain it though u divide the forces and at the end get 45 degrees :D

[nachi88]

the answer is 45 i had to solve such a problem in school in 10th grade i dont think i can explain it though u divide the forces and at the end get 45 degrees :D

no you are wrong. It is 45 if you are on a plain ground.

If you are on a elevation, the answer is slightly different, but around 45.

you ask some similar problems also.

[_GrimReaper]

hmmmm i cant think of any math ones right now
heres an alternative:)
Ronaldinho and adriano are ona bus along with the rest of the team. they are high in the mountains. suddenly ronnie realises he has to go pee.the bus stops for him to do pee .he and adriano get out. after 1 min the bus goes on without them and after 10 m a giant tree fals down and crashes the bus. in this moment adriano says
-Damn nigga, i wish we were in the bus right now.
why does he say that???

[nachi88]

-Damn nigga, i wish we were in the bus right now.
why does he say that???

becuase if both were in the bus, their weight would have caused the bus to be more slow and they would have missed the tree, and would have gone from that point only after the tree fell. ( I cant say it in english properly)

try the artillery problem... its intresting

[_GrimReaper]

the answer is very similar and has nothing to do with weight

[nachi88]

the answer is very similar and has nothing to do with weight

if they both did not get off to pee, the bus would have passed the point where the tree falls much before the tree fell.

[_GrimReaper]

yep

how many triangles max can u mace with 6 matchsticks

[nachi88]

how many triangles max can u mace with 6 matchsticks

we can make 4 maximum

put 3 in a triangle shape as a base. from each corner of the traingle,put one matchstick towards a top point. the three corners vertical matchsticks will make another 3 triangles, at that top point

something like the pyramids of egypt, with a triangular base.

[besiktas1903]

is the holiday question related with math number pi?
by the way the 1/n series question i think can also be solved by expressing this sum as a sum of infinite geometric series whose elements decrease by a factor of 1/2 with the first term of each being 1/k, where k is a prime number.
as for the 2222^5555+5555^2222 mod 7 question, the expression can be written as (7*k+3)^5555+(7*n+4)^2222 mod 7 =3^5555+4^2222 mod 7, and since 3^6 mod 7 and 4^3 mod 7 both yield 1 it can be written that 3^5+ 4^2 mod 7=0.
the animal question seems to be also applicable for sheep&cow, too.
and for the back-to-back, can an alternative be the existence of two j or m?
as warm-ups:
if eight is taken away from nine, one is achieved. in addition, if eight is added to nine, five is achieved. how?
in addition:
x=y
x*x=y*x
x^2-y^2=y*x-y^2
x+y=y
x=0
1=0?
