TAKE THE JETS CHALLENGE
Can you solve this JETS challenge problem? The answer will appear in next week's
edition of the Friday Update!
The Challenge of the Mercury Vapor
Last year the University of Virginia recycled 31 miles of fluorescent lamps with
0.5 milligrams of mercury per kg of bulb, but if released to the environment, it
can become a highly toxic vapor. Each bulb is a cylinder that measures 48" long
by 1.25" diameter, with a mass of 284 grams.
How many kgs of mercury were prevented from entering the atmosphere.
Answer to last week's MATHCOUNTS problem:
If 10 of 32 did work for the makers recently, then 22 of 32 did not. This is 22
¸ 32 = 69%.
--------------------------------------------------------------------------------
The vote was 14 to 8 against, but when the other 10 votes are added, which were
1 to 9 against, we get a vote of 15 to 17 against. The drug passed by 17 – 15 =
2 votes.
--------------------------------------------------------------------------------
We know that there are the 9 votes for it and the 1 vote against, and then there
are the other 22 members of the panel to consider. Two of them did not vote, so
there are only 20 votes to figure out. Since they voted in the ratio 3:2 to
withdraw the drug, we can set up the following equation: 3x + 2x = 20, so 5x =
20 and x = 4. This means that there were 3 ´ 4 = 12 against the drug and 2 ´ 4 =
8 in favor of the drug. There were a total, then, of 9 + 8 = 17 votes in favor
of keeping Bextra.
