Sorry, all, but I forgot to post the answers in the usual timely manner. Here they are. I promise to do better on the next quiz.
Tough Test 7 - Answers
1. Fraction of the pole in the ground = ½.
Fraction of the pole covered by water = 1/3.
Fraction of pole in ground, covered by water = ½ + 1/3 = (3+2)/6 = 5/6.
Fraction of pole out of the water = 1 - 5/6 = 1/6.
Thus, one-sixth of the pole (out of the water) is 11 feet.
So, total length of the pole is 6 X 11 feet = 66 feet
2. One
3. Little Big Man
4. One twelfth
5. Two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame-seed bun.
6. Assuming 6 legs for each insect, 26 insects will have 156 legs. However, there are 172 - 156 = 16 extra legs. It is important to note that spiders have 8 legs and flies have 6 legs. So, there are 2 extra legs per spider in the web. Thus, the extra 16 legs belong to 8 spiders
7. Bob weighs 180 pounds.
8. Seven-up
9. Inkstand
10. Lakes may have numerous inflows, but no lake has more than one outflow. Arrange to meet at the outflow. It was stated that you could walk around the lake, so presumably you will be able to find a place to cross the outflowing stream if necessary.
