Based
on the article “How much plastic is floating at sea? 270,000 tons,
says study” on page A5 of the Thursday, December 11^{th},
Seattle Times.

7.A
recent study by the 5 Gyres Institute has estimated that there are
270,000 tons of plastic pieces floating in the oceans. 75% of this
plastic is in pieces 8 inches or longer. 35,540 tons of the plastic
is in pieces less than one-fifth of an inch. What percentage of the
plastic in the oceans is in pieces between one-fifth of an inch long
and 8 inches long?

A. 7.2%

B. 9.9%

C. 12%

D. 25%

8.
The study estimated that there are 5 trillion pieces of plastic in
the oceans. The most common type of plastic in the ocean is
polystyrene, a material that is typically hard, clear and
comparatively brittle. Polystyrene has a density of 66 pounds per
cubic foot. What is the average volume of the pieces of plastic in
the ocean?

A. 0.000020 in^{3}

B. 0.00024 in^{3}

C. 0.0028 in^{3}

D. 0.034 in^{3}

9.Tiny
plastic pieces in the ocean, those that are less than one-fifth of
an inch in any dimension, make up about an eighth of all the ocean
plastic by weight. How many grams would a polystyrene cube with
sides one-fifth of an inch weigh? (1 lb. ≈ 454 g)

A. 0.042 grams

B.0.14 grams

C. 1.7 grams

D. 9.1 grams

“U.S. urged to build new generation of hydrogen bombs” on page A4 of
the Monday, December 1^{st}, Seattle Times.

4.In 1967 the U.S controlled 31,000 nuclear weapons. Since then
the supply of nuclear weapons controlled by the U.S. has decreased
steadily and it now stands at 4,804. If the number of weapons the
U.S. controlled in a given year is best modelled by an exponential
equation, on average by what percentage did the U.S. reduce its
nuclear weapon stockpile each year?

A. 1.8%

B. 3.9%

C. 6.7%

D. 15.5%

5. A large portion
of the nation’s nuclear weapons are designed to use plutonium-239, a
radioactive isotope with a half-life of 24,000 years. The half-life
of an isotope describes how long the exponential decay of a sample
will take to reduce it to half of its original amount. Significant
portions of most plutonium-239 samples have plutonium-240
impurities, a less-stable isotope with a half-life of just 6563
years. If a nuclear warhead was assembled in 1954, what percentage
of the plutonium-240 in it would have decayed?

A. 0%

B. 0.63%

C. 0.78%

D. 0.91%

6. Nelson Cruz has
historically struggled at Safeco Park, hitting safely in just 43 of
his 184 at-bats for a batting average of .234.He will likely be the Mariners’ designated hitter, a position
of a weakness last year, especially at Safeco. Seattle designated
hitters combined for a batting average of .191 on their 289 at-bats
during the 81 home games. If Cruz can match his previous batting
average, how many more hits will he produce at home next year than
the Mariners’ designated hitters did this year?

A. 11 more hits

B. 23 more hits

C. 57 more hits

D. 68 more hits

7.Cruz hit .271 last year all year, but hit especially well close
to home. He hit .298 while playing either at his home park in
Baltimore or the other hitter-friendly parks in the AL-East
division. Of the 162 games in the season, only 43 of them were
played at parks outside the AL-East. What was Cruz’s batting in
non-AL-East parks?

A. 0.196

B. 0.227

C. 0.244

D. 0.261

8.The EPA plan calls for two dozen acres of the river bottom to be
capped with rock and sand and for 105 acres to be dredged, removing
polluted material. The plan also calls for 235 acres to eventually
be covered by fresh materials flowing downstream. What fraction of
the acres of river bottom in the EPA plan will be dredged?

A. 15/52

B. 21/68

C. 21/47

D. 47/73

9.The plan calls for 1 million cubic yards of polluted material
to be dredged from river bottoms. The dredging will occur over 105
acres. What will be the average depth of the dredging? (1 acre =
43560 square feet)

A. 0.66 yards

B. 1.36 yards

C. 2.0 yards

D. 210 yards

10. Examine the
graph titled “Early action areas” on page A7. The bar graph details
when and where contaminated material has already been removed from
the Duwamish. Including the material slated to be removed under the
new EPA plan, what fraction of the total cubic yards of contaminated
material have yet to be removed?

A.

B.

C.

D.
