4 Problems with matches.

1.
 I have a box of matches. I can form with them any given pair of four
regular figures (an equilateral triangle, a square, a pentagon and a
hexagon), using all the matches every time. Thus, if there where 11 matches,
I could form the triangle(6) and pentagon(5) or the pentagon(5) and
hexagon(6), or the square(8) and the triangle(3) but I could not with 11
matches form the triangle and hexagon. You must decide yourself how many
matches each side of the figures need, as long as all figures are regular.

What is the smallest number of matches I need to make any given pair?

Above you see twenty matches which form two enclosures
grouped in 6 and 14 matches so that one is exactly three
times as large as the other.
Can you make two groups of 7and 13 so that one is also
exactly three times as large as the other?

Above you see six matches arranged in a way that they represent
Roman number 57. Replace any two of them to represent 0.

So You want to take the day off !

From Marietta Begley.

Lets look at what you are asking for.

 There are 365 days per year available for work.

There are 52 weeks per year in which you have 2 days off per week, leaving 261 days available for work.

Since you spend 16 hours each day away from work, you have used up 170 days, leaving only 91 days available.

You spend 30 minutes each day on “coffee” break. That accounts for 23 days each year, leaving only 68 days available.

With a one hour lunch period daily, you have used up another 46 days leaving only 22 days available for work.

You normally spend about 2 days per year on sick leave. This leaves you only 20 days available for work.

We offer 5 holidays per year, so your available working time is now down to 15 days.

We also generously give you 14 days vacation per year which leaves you only 1 day available for work and I’ll be damned if your going to take that day off!

 

How old is your Granddad?

Ask him to think of the month he was born.

Double the  month.

Add 5 to the total

Multiply by 50

Now add on his age

Subtract 250

And tell you the answer

 The first digit is the month and the last two are the persons age. If it is a four number answer then the first two numbers are the month.

There are 8 different ways that three coins can turn up when tossed.
e.g. HHH or TTT or HTH or etc.
Place each of the 8 results binS on the eight lines so that, to get from one line to the adjacent line,
you have only changed one letter!

7 You may have to do a bit of research and some estimating to figure out which
value is larger. Explain how you arrived at your answer.


Which is larger?


1. The energy released by exploding a stick of dynamite or the energy
released by burning a paraffin candle of the same size?

2. The energy released by a 15 kilo-ton nuclear bomb or the total
food-energy used by an average human male during his lifetime?

3. The kinetic energy of a 16 pound bowling ball moving at Earth escape
velocity, or the total calories obtained by eating ten thousand donuts?

4. The energy of the light that enters the eye in one minute while looking
directly at the sun from the distance of the planet Neptune, or the energy
of the light that enters the eye in one minute while looking directly into a
conventional 100 watt light bulb from one meter?

5. The energy used by your brain in one day, or the energy used by the
average Mallard duck to fly 50 miles?

6. The energy an average house fly uses to crawl up a 20 foot wall, or the
energy used by a human to blink once?

9 Some rhyming riddles I found
Answers in rhyme are ... yes most appreciated


1. If my 4 were a 9,
And my 6 were a 3.
What I am would be one,
Less than half what I'd be.
I'm three little digits,
Just three in a row,
So what in the world
Can I be? Do you know?


2. The square of nine is 121!
It looks a trifle queer,
But still I say it's really true,
The way we figure here.
And nine times ten is 132:
the selfsame rule, you see,
So what d'you say I have to write
For five times twenty-three?


3. Said a feller out felling a tree
"My age I've divided by three.
The result is a square,
Yet my age, I declare,
Is six times a cube, Glory be!"

4. "You want my age?" said Auntie Liz.
"You shouldn't ask, but here it is.
You switch its digits: that will show
Just half my age ten years ago."
The clues are there, so you can see
How old dear Auntie Liz would be.


5. If nine times ten were one two three --
That's just the way it's read --
Then what d'you think you'd have to say
For nine times five instead?


6. If my first were a 4,
And my second a 3,
What I am would be double
The number you'd see.
For I'm only three digits,
Just three in a row.
So what must I be?
Don't say you don't know!


Have fun...

1. A cunning old codger called Kaid,
Got eighty-four bucks for some jade.
His profit per cent,
In cents for the gent,
Was half the amount he had paid.

How much was that?



2. There was an old lady in Sheen,
Whose grandchildren numbered sixteen.
Four-ninths of the boys,
Were too old to want toys,
So how many girls must that mean?



3. There was a young lady of Lee,
Whose age had its last digit three.
If you total the two,
Which is easy to do,
One less than a square you will see.



4. "My age?"answered Barbara Blatt,
"just keep it right under your hat.
Adding one to each figure,
Makes it nineteen years bigger,
Than half what it is."So what's that?


5. "Exactly two hundred,"you say?
But it's seven whole months to the day.
You're fifteen days short,
In your adding, old sport,
For those seven months I'm away.

What months would he be away?



Have fun..
