In 1932, my dad was as old as the last two digits of his
birth year.  When he mentioned this interesting coincidence
to his grandfather, my dad was surprised when his grandfather
said the same thing was true for him as well.  Believe me,
it's quite possible and I am able to prove it too.  How old
was my father and his grandfather in 1932?

Limerick Problem #1:
 Three different one-digit primes produce me, if you're using times;      If my digits you add,    Another prime will be had.  Two answers--and nothing else rhymes.

Limerick Problem #2:
 There once was a cube 'twas found Whose two digits, when switched clear around,          Was the product (quite fair)             Of a cube and a square,    And its name will most surely astound.

 Each day, I was allowed to catch fish until the next fish I caught was heavier than any previous fish I caught that day, or
 Each day, I was allowed to catch fish until the total weight of fish caught that day exceeds 10 pounds.

Now, assume that the fish in Bayes Lake had random weights
between 0 pounds and 10 pounds plus the costs of the two

 Subj:     MATH PROB. - The Alaskan Pipeline (S669)           From: MathNexus.wwu.edu on 11/2/2009 Drawing from MathNexus...
Source: http://mathnexus.wwu.edu/Archive/problem/detail.asp?ID=138

Joe Flubb had contracted to replace a 2-mile section of
oil pipeline in the far north. The replacement needed to
be done during the coldest part of a bitter cold winter
many miles north of the Arctic Circle.  The thermometer
dropped to 40 Celsius degrees below zero on the day Joe
and his crew installed the new section of pipeline, so
understandably he was anxious to get the job completed
as quickly as possible.

According to the specifications, the new 2-mile pipeline
was to be firmly anchored to the ground at each end.  The
specs also required that expansion joints be placed at
appropriate points along the new pipe to allow for expan-
sion of the pipe when the temperature would go up.  This
precaution seemed quite unnecessary to Joe because the
metal he was using in the pipeline had an expansion
coefficient of only 0.00005.  This means that every time
the temperature increases by 1 degree Celsius, each foot
of pipe grows by 0.00005 feet.  That's only 6 hundredths
of one percent of an inch per foot of pipe.  Clearly such
a minute expansion could be ignored, Joe decided.

To make a drawing of the extended pipeline after the
temperature increases, points A and B are 2 miles apart
and where pipe is firmly anchored to the ground.  Point
C in the midpoint of AB.  For ease of computation, assume
that as the pipeline expands, the pipe lifts off the
ground to a point D directly above point C (i.e. DC is
perpendicular to AB), forming straight segments AD and BD.
Thus, point D is the highest point of the pipe.

Summer finally arrives.  The temperature soars to 30
degrees Celsius.  The pipe will expand a bit.  Try to
guess and determine:

How high is CD?
Could a mouse squeeze under the pipe at C?
Could a sled dog squeeze under?
A polar bear?

 Subj:     MATH PROB. - Egg-Citing Eggs-Perience (S668)            From: MathNexus.wwu.edu on 11/16/2009 Drawing from MathNexus
Source: http://mathnexus.wwu.edu/Archive/problem/detail.asp?ID=144

A woman went to a local outdoor market with 20 eggs,
another woman went with 30 eggs, and a third woman
went with 50 eggs.  All three women sold their eggs
at the same rate and received the same amount of money.
How could this be?
.
............
.
Note: M.N. (Bellingham) has already submitted the
clever solution of "0 eggs/hr. (if the rate is time)
or \$0/egg (rate is cost per egg)."  So, let's remove
that possibility and assume that the rate exceeded
the infamous value of 0.

Hint: When thinking in terms of a rate, think in terms
of both "dozen eggs" and "single eggs."

 Subj:     MATH PROB. - 9-Digit Pandigital (S666)           By Dave Ellis           From: Anonymous Jr. on 10/10/2009
Source: http://www.puzzlet.co.uk/Puzzlets/Puzzlet_002.html

A pandigital is an integer containing every digit.  In this
particular case, we're dealing with the 9-digit pandigital,
since the zero isn't used.

Take all the digits 1 through 9 in order, and insert as
many plus and minus signs as you wish, wherever you want,
to make an arithmetic sum of 100.  For example,

123 + 45 - 67 + 8 - 9 = 100

Are there any more ways of punctuating a 9-digit pandigital
with plus and minus signs to make a sum of 100 as in the
example above?  If so, what are they?

already have passengers.  The numbers on the taxi cabs are
405, 73, 280, 179, 440, 301, and 218.

Suppose you want to estimate the number of taxi cabs in the

service, how can you use the observed numbers to estimate N,
the total number of taxi cabs in the city?

How many taxis do you think there are?  How can you test
