1. If 29 frogs catch 29 flies in 29 minutes, how many frogs are required to catch 87 flies in 87 minutes?

 

 

2. A woman has 43 pairs of stockings in her drawer: 21 blue, 8 black, and 14 striped. There was a brownout and she cannot see into the drawer. How many stockings must she take out to make certain that she has a pair of each?

 

 

3. A census-taker calls at a house. He asks the woman living there the ages of her three daughters. The woman says, " If you multiply their ages the total is 72. If you add together their ages the sum is the same as the number on my front door which you can see."

The census-taker says,"That is not enough information for me to calculate their ages." The woman replies."Well, my eldest daughter has a cat with a wooden leg."

The census-taker says," Thanks. Now I know their ages."

 

What is the number on the woman's front door. What are the ages of the three daughters?

1. 29 frogs

2. 36 pairs - assuming the stockings are rolled or stored in pairs.

3. 15. 2,4,9. - did I get it right?

#3 has several solutions pala.

 

Pwedeng:

3,4,6 totaling 13

3,3,8 totaling 14

2,6,6 totaling 14

2,4,9 totaling 15

 

Since the eldest has a cat, that probably means that she doesn't have a twin, so 2,6,6 is out. I can't get the significance of the wooden leg. Does it have anything to do with 9 lives, less one since it lost a leg?

Not bad... Not bad at all. You got #1 and #2.

 

There is really only one solution to # 3. I believe you are almost there.

 

Note: There are 12 possible combinations to work with.

Math for Fun:

 

 

The great grand son of Einstein offered this proof that 1 = 2.

 

 

He says:

 

Assume a = b

 

1. multiply the equation by b

 

ab = bb

 

2. subtract aa from equation

 

ab - aa = bb - aa

 

3. factor difference of squares

 

ab - aa = (b-a)(b+a)

 

4. factor left handside

 

a(b-a) = (b-a)(b+a)

 

5. divide by common factor (b-a)

 

a = b+a

 

6. substitute a for b (following assumption that a =

 

a = a + a

 

7. simplify

 

a = 2a

 

8. divide by common factor( a )

 

1 = 2

 

 

"That was neat, but you did an illegal operation," said the great grand daughter of Da Vinci.

 

 

What was theillegal operation?

 

anong sagot dito? thanks

patulan ko ba toh? cge na nga..

 

5. divide the the common factor (b-a)

 

if a=b ( assumption no. 1) then b-a=0, therefore you cant divide any number by ZERO.

Excellent edzabu !

 

 

Here is another one.

 

CHESS MOVES

 

 

The number of possible ways of playing the first four moves for both players in chess is 318,979,564,000.

 

How many different moves can be made in the first ten moves of each player?

next question na....

[slayersburns]

back in college dayz....

 

algebra : take 5

 

trigo : take 2

 

geometry : take 1

 

calculus : take 4 (binayaran ko pa)

 

well itz all done now...eheheh

 

luv math!

back in college dayz....

 

algebra : take 5.........meok lang

 

trigo : take 2.....ok lang

 

geometry : take 1...oklang

 

calculus : take 4 (binayaran ko pa) ....exempted me

 

well itz all done now...eheheh

 

luv math!

So far ilove numbers so much.......ang naexempt kona subject chemistry, calculus and accounting....yong math calculuslang

[coldfussion]

i took up computer engr kaya dami kong math before...

kala ng iba ala kaming ganong math...doon sila nakamali...try nyo mag aral sa MAPUA at makikita nyo sinasabi ko...

Differential & Integral Calculus!

[shodandille]

buysit na algebra 2 class yan! lagi akong inaantok! pumasa nga ko pero puro naman cramming before a big test to try and understand in ONE night everything i should've been learning for 2 weeks! ahh.. puro stress non.

 

but im a geometry addict
