UPCOMING EVENTS:

VOLUNTEERS NEEDED!
Volunteers from all engineering disciplines are needed to interview Boise State Students for the 2008 Outstanding Engineering Student Awards. Volunteers will make the selection of the outstanding student in each of the three disciplines (CE, ME, and EE) at Boise State. The time commitment will be one evening for approximately 3 hours at the end of January or early February. The interviews will take place at Boise State University. All student nominees will be honored at the Engineers Week Banquet on February 21. If you would like to volunteer please e-mail Heather Carroll at hcarroll@dohertyeng.com.

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's edition of the Friday Update!

Elections
Elections – With the start of 2008 comes a rash of caucuses and primaries to determine who each party will choose to run in the national presidential election. In light of this, here are a few questions surrounding voting, percentages, etc.

On January 3rd, both the democratic and republican parties in Iowa saw a record number of voters turn out for the caucus. In 2004, the Democratic Party had 124,000 at the caucus. This year, the Democratic Party had a turn out of 227,000 voters. By what percent did this year’s democratic voter participation beat 2004 democratic voter participation? Express your answer to the nearest tenth.
--------------------------------------------------------------------------------
In Mr. Hoolihan’s 8th grade Social Studies class, students are holding mock-elections to learn about our nation’s voting process. In this class exercise, only Vonda, Emma, Frank, and Bobby are running for the class republican bid for president. During the “primary vote” Vonda received 10% of the votes, Emma received 35% of the votes, Frank received 30% of the votes, and Bobby received the rest of the votes. If Bobby received 10 votes, what was the difference between the least number of votes received and the greatest number of votes received by the four candidates?
--------------------------------------------------------------------------------
After the “primary vote,” Vonda dropped out of the race. If Vonda had dropped out before the “primary vote,” what is the minimum percentage of Vonda’s votes that Frank would have had to receive in order to beat Emma in the primary vote?

Answer to last week’s MATHCOUNTS problem:
The coins come from 50 different years. Since there are 100,000,000 coins, there are 2,000,000 coins from each year. (100,000,000 ÷ 50 = 2,000,000)
Coins from 1958 through 1981 have a mass of 3.1 grams each, so there are 48,000,000 coins with a mass of 3.1 grams each. (2,000,000 coins × 24 years = 48,000,000)
Coins from 1982 through 2007 have a mass of 2.5 grams each, so there are 52,000,000 coins with a mass of 2.5 grams each. (2,000,000 × 26 years = 52,000,000)
(48,000,000 coins)(3.1 grams) + (52,000,000 coins) (2.5 grams) = 278,800,000 grams
--------------------------------------------------------------------------------
First we need to figure out how many bags there were and to do that we need to know how many grams each bag weighed.

(30lbs/bag)(453.59grams/lb) = 13,607.7 grams/bag

278,800,000 grams ÷ 13,607.7 grams/bag = 20,488.40 bags

Now we divide the total number of bags by the number of people pouring.

20,488.40 ÷ 100 = 205 bags per person, to the nearest whole number.
--------------------------------------------------------------------------------
First we need to find the volume of each penny.
 

V = πr²h

r =d

r = (0.75) = 0.375

            V = π(0.375)²(0.061)

            V = 0.0269489745 cubic inches per penny

Next multiply the volume of one penny by the total number of pennies.
(0.0269489745)(100,000,000) = 2694897.45 cubic inches

Convert the volume to cubic feet.

(2694897.45 in3) ÷ (1728 in3/ft3) = 1559.5471 ft3

Now we can solve for the height that the melted penny mixture would reach.

V = l×w×h
1559.5471 = 30×165×h
1559.5471 = 4950×h
h = 0.32 ft, to the nearest hundredth
--------------------------------------------------------------------------------
First divide the number of pennies by the number of pennies sucked up per minute.

100,000,000 pennies ÷ ($1000 × 100 pennies per dollar) = 1000 minutes

Now convert minutes into hours.
(1000 minutes) ÷ (60 minutes per hour) = hours
