FUTURE CITY JUDGES NEEDED
The Future City Competition is right around the corner and volunteers are needed
to help judge each team's city. There are 21 schools attending the final
competition out of 31 registered with 34 entries each which has a Computer City
Design, an Essay Abstract, and City Model that need to be judged which is almost
double the number of entries from last year! Below is a list of the judges still
needed along with a description of the time commitment and effort involved.
Presentation judges are needed the most and the ones that have the most fun
listening to the presentations and asking a few questions. Some of the schools
have been working on their city since August and will be traveling from Montana
and Salt Lake City so please consider giving up a few hours of your time for a
great program! If you are able to volunteer, please contact
Meghann Donley by email as soon
as possible to get signed up! I hope you are able to join us on January 6th and
if you know of anyone else that might be interested please forward this email to
them. Thanks again to all of those that have volunteered this year and in the
past!
ESSAY/ABSTRACT JUDGES -
Judging will take place: Dec. 14th - Jan. 3rd
Teams were asked to develop an engineering feasibility plan for an identified
redevelopment tract of land within their city. In addition to the 500-700 word
essay the teams also wrote a 300-500 word city abstract describing their future
city and some of its services. Judges are asked to evaluate the paper’s content
and creativity (at their leisure) based on specific guidelines. Background
information on the topic along with key points will be provided. Time commitment
is estimated at 6 hours.
CITY MODEL JUDGES -
Judging will take place: Jan. 6th, 8:00am-Noon at BSU
Teams were asked to build a scale model of a section of their city. Judging
teams must evaluate the creativity, attractiveness, accuracy, and moving
components of the model. Judges will be given scoring sheets with specific
criteria to evaluate teams. Time commitment is estimated at 4 hours.
PRESENTATION JUDGES -
Judging will take place: Jan. 6th, 8:00am-Noon at BSU
Each team will prepare a 5-7 minute presentation discussing their city and its
amenities. Students will be evaluated on how well they can explain the design
and function of their futuristic city. Judging teams must ask students at least
three questions after their presentation. Samples questions will be provided.
Scoring sheets with specific criteria will be given to the judges to evaluate
teams. Multiple teams of judges will be evaluating the teams during the time
period. Time commitment is estimated at 4 hours.

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Holiday Decorations
The students in Mrs. Ulstad’s Math class designed the decorations that are hung
on the city’s street-light poles. Each decoration is either in the shape of an
equilateral triangle or a regular hexagon. The perimeter of each decoration is
24 feet. What is the ratio of the area of the triangle to the area of the
hexagon? Express your answer as a common fraction.
________________________________________
In December, 1990, a holiday tree in the shape of a right circular cone had a
height of 8 feet and a radius of 2 feet. By December 1991, the tree’s height and
radius each increased by 10%, and the tree’s measurements continued to increase
each year at a rate of 10% of its previous year’s size. In December, 2006, the
tree will be decorated with lights. The lights will be placed along the curved
lateral surface of the tree at the rate of one light per square foot. No lights
will be placed within the branches or on the underside of the tree. The formula
for the lateral area of a cone is LA = π × r × l where r is the radius and l is
the slant height of the cone. How many lights are needed to decorate the tree in
December, 2006? Express your answer to the nearest ten.

Each year Mario gives his sister a gift that is wrapped in five boxes that are
five similar rectangular prisms. After she unwraps the first box, there is
another box inside to be unwrapped, and then another and another and another.
She does not get to her gift until she has unwrapped all five boxes. The length,
width, and height of the smallest box are 4 inches, 2 inches, and 1 inch
respectively. The dimensions of each larger box are 20% greater than the
dimensions of the previous smaller box. By what factor does the volume of the
smallest box need to be multiplied to obtain the volume of the largest box?
Express your answer as a decimal to the nearest tenth.
Answer to last week’s MATHCOUNTS problem:
Norm’s interpretation discounts the original price by 50% of the original price,
13.99 − (0.5 × 13.99) = $7.00. Sara’s interpretation discounts the original
price by 35% of the original price to get the sale price and then discounts the
sale price by 15% of the sale price, 13.99 – (0.35 × 13.99) = 9.09, 9.09 – (0.15
× 9.09) = $7.73. Norm’s interpretation of the advertisement leads to the least
purchase price. The positive difference between the interpretations is |7.73 −
7.00| = $0.73.
________________________________________
The price of a 22-pound turkey is 22 × 1.19 = 26.18 or $26.18. This amount will
be saved if $100 in other groceries is purchased. However, if only $90 in other
groceries is purchased, then the customer will have to pay the $26.18 for this
turkey, which comes to a total of 90.00 + 28.16 = $116.18. Norm spent 116.18 −
100.00 = $16.18 less than Sara to get his groceries and turkey.
________________________________________
The cost of a 22-pound turkey at $0.19 per pound is 22 × 0.19 = $4.18 since Norm
is spending more than $25 on other groceries. The total cost of the groceries
and a 22-pound turkey is 80.00 + 4.18 = $84.18.
________________________________________
The amount saved is 100.00 − 84.18 = $15.82. The percent savings is the amount
saved divided by the cost of the groceries at Shopwise Market. 15.82 ÷ 100 =
0.1582 or 16%.
