MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Happy Darwin Day
On February 12, 2009, scientists around the world celebrated “Darwin Day,” the
200th anniversary of the birth of Charles Darwin. Charles Darwin was a British
naturalist who proposed a theory of evolution by natural selection. 2009 also
marks the 150th anniversary of the publication of Darwin’s landmark book, The
Origin of Species, in which he detailed a series of meticulous observations that
led him to develop his theory.
In brief, the theory of evolution by natural selection suggests that the
individuals that are best adapted for survival (the strongest, fastest,
smartest, etc…) will have a higher survival rate and, as a result, a higher rate
of reproduction. It follows that those individuals best adapted for survival
have greater opportunity to pass along their genes and, as a result, drive the
evolutionary changes within a species, and over time, end up creating new
species.
Use the following scenario to answer questions 1 – 3.
Suppose that at the start of 2009, the monkeys on Cayo Island are classified as
being in one of two groups based on their fur color. Group A contains monkeys
with a vibrant orange fur that makes them very easy for predators to detect and
Group B contains monkeys with brown fur, which enables them to hide in trees and
avoid detection by predators. Group B’s brown fur allows its members to survive
longer and have a higher rate of reproduction than monkeys in Group A. As a
result, the population of Group A doubles every 5 years, while the population of
Group B doubles every 4 years. Through the classification/identification
process, it was found that Group A has 200 monkeys and Group B has 25 monkeys.
1. How many monkeys will there be in each group at the start of 2029?
-----------------------------------------------------------------------------
2. At the start of what year will the population of the two groups be equal?
-----------------------------------------------------------------------------
3. Assuming that the population has more than enough resources available to them
to continue this growth pattern, what percent of monkeys will be in Group B in
2109?
Answer to the last MATHCOUNTS problem:
To solve this we can set up a proportion.
34,800,000 hits/0.06 sec = x hits/1 sec
Solving for x, we see that x = 580,000,000. In scientific notation that is 5.8 ×
108 hits.
-----------------------------------------------------------------------------
First let’s figure out how many people 0.1% of “a quarter of a million” is.
0.001(250,000) = 250 people
If each of those 250 people sold their one ticket for an average of $20,000,
that means 250($20,000) = $5,000,000 was generated.
-----------------------------------------------------------------------------
First let’s figure out the rate at which Harrison spoke.
8445/(60+45) = 8445/105 = 80.428571… words per minute
Now let’s figure out the rate at which Obama spoke.
2401/18.333333 = 130.963636… words per minute
Thus, the positive difference between the rates of speech is 130.963636 –
80.428571 = 50.5 words per minute.
