House Bill 760 and House Bill 761
ISPE President Elect David Schiess recommends that engineers look into House
Bill 760-761,
http://www3.state.id.us/oasis/H0760.html,
http://www3.state.id.us/oasis/H0761.html,
which will give tax credits to wind developers in Idaho. Members should look
into it and decide if they want to support this bill sponsored by George
Eskridge of Dover. Dave has had the developer call and request the engineering
community support their efforts to bring wind power to Idaho. There seems to be
several potential projects in South East Idaho. For further information you can
contact David Schiess as
dschiess@datawav.net.

NSPE Spring 2004 Ethics Forum
March 24, 2004: Conflict of Interest
April 21, 2004: Professional Competency
May 19, 2004: Protection of the Public Health & Safety
The National Society of Professional Engineers, in cooperation with the Board of
Ethical Review will present the NSPE 2004 Spring Ethics Forum, a series of three
web seminars, beginning in March 2004. Each 60-minute session will address
critical ethical issues facing practicing engineers and other design
professionals. BER representatives will offer an in-depth analysis of the
selected cases and arguments presented prior to publishing the final opinion.
The series will be moderated by NSPE Deputy Executive Director and General
Counsel Arthur E. Schwartz, Esq.
Registration: Enroll in one online seminar for $149 per site connection. Enroll
in the series of three seminars for $399. All participants will receive
documentation of the PDH credit for submission to state licensure boards.
CPC-PDH credit. Each 1-hour seminar earns 1 PDH.

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Math for MATHCOUNTS
Math is needed to put MATHCOUNTS together. From registration statistics, to
creating the handbook, to making arrangements for the National Competition, a
lot of math is necessary throughout the year.
--------------------------------------------------------------------------------
Let’s use some of our registration statistics to work backwards. Remember that
every school can send one team of four students and/or up to four individual
students who compete alone and not as part of a team. In 2004 there are 5931
four-member MATHCOUNTS teams registered. If team members make up 62.3% of all of
the students registered for MATHCOUNTS, how many total students are registered?
Express your answer to the nearest hundred.
--------------------------------------------------------------------------------
Some schools register just a team; other schools only register a few individual
kids; and some schools register both teams and individual kids. If the ratio of
the number of schools registering at least a team to the number of schools only
registering individuals is 550:11, how many total schools registered students
for MATHCOUNTS? Express your answer to the nearest ten.
--------------------------------------------------------------------------------
Once students are registered, we need to provide problems for competitions and
for the School Handbook. Many of these problems include diagrams. Consider a
handbook question that refers to a standard piece of paper measuring 8.5 inches
by 11 inches. If we want to provide a scale drawing of this piece of paper, and
the shorter side of the paper is drawn with a length of 1.7 inches, what is the
length we need to use for the longer side?
--------------------------------------------------------------------------------
Drawing something as simple as an isosceles triangle can be tricky on the
computer. Consider the isosceles triangle ABC, with legs AB and BC each
measuring 20 cm and base AC measuring 30 cm. In order to make a scale drawing,
we’ll draw segment AC as a horizontal line of length 3 inches. (Our drawing
program uses inches rather than centimeters.) Now, I know that the other two
sides will be drawn with a length of 2 inches, but getting them at the right
angle is sometimes tricky. If we start with side AB as a horizontal segment on
top of segment AC, how many degrees must we rotate segment AB about A so that it
is at the correct angle? (In other words, what is the measure of angle BAC?)
Express your answer to the nearest whole number.
--------------------------------------------------------------------------------
Preparations have already started for the 228 Mathletes who will be attending
the National Competition this May. Mathletes are assigned to hotel rooms in
pairs, such that all rooms will have two Mathletes of the same gender (but maybe
not from the same state). If there is a student without a same-gender pairing,
that student will get his/her own room (with an adult chaperone). Since
reservations must be made before we know exactly who is attending, what is
greatest number of rooms that MATHCOUNTS would need to reserve to house all of
the Mathletes?
Answer to last week's problem:
We need to calculate 67 ÷ 179 to see that he will still receive 37% of the
money he would have received if he had continued on in Texas.
--------------------------------------------------------------------------------
Since we’re saying that the batting average and the price of the jersey are
proportional, we can set up the following proportion: .294 / 99.99 = .324 / x,
where x is the cost of a Jeter jersey. If we find the cross products and solve
for x, we see that x = (.324 × 99.99) ÷ .294 = $110.19.
--------------------------------------------------------------------------------
First we can figure out how many hits he had. Since 29.8% of his 607 at-bats
resulted in hits, he had .298 × 607 = 180.886 hits. Now we’re told that 16.57%
of these were doubles, so he hit .1657 × 180.886 = 30 doubles, to the nearest
whole number.
