Geometry/Honors Geometry Summer Packet

Geometry/Honors Geometry Summer Packet
Dear 2016-2017 Geometry and Honors Geometry Students:
Summer is a wonderful time for relaxing, reading, traveling and visiting
with family and friends. However, that wonderful time away from
school, as relaxing as it can be, is not good for academics. Since
mathematics is a skill like playing a sport or a musical instrument, lack
of practice can get in the way of mathematical success.
The enclosed problems will help you review the algebra skills that you
will continue to use in geometry. The packet will be collected on
Wednesday, August 17th, graded and will count as a homework
assignment for the first quarter of the upcoming school year. Also,
during the first week, there will be a 50-point Test on the same material.
I have included my email, if you have questions. Also, at the end, there
are some resources that can help you. If you have a lot of trouble
completing the problems in the packet, I highly recommend the Algebra
Brush-Up session the week before school begins.
The work is to be done on loose leaf paper and graph paper. Be sure to
read and follow the directions. I will collect this on Wednesday, August
17, 2016. No late work will be accepted.
Enjoy your summer and I look forward to meeting you in August.

FOR FUN!
SOME MORE FUN!
Brain Teasers
Here are some "math" problems that will put your logical and number sense skills to
work. Most of which do not require algebra to solve, but for some of them,
algebra can be helpful. Some are slightly tricky, in that you need to read the statement
of the problem very carefully. Have fun!
Brain Teasers 1
1. A man buys a seagull and a fish for a total of $1.05. The seagull costs a dollar more
than the fish. How much did each cost?
2. Half the employees in a firm went to lunch at noon. Since then, 25 have returned
and 7 others have gone out. At this point, there are twice as many people working as
there are people out to lunch. How many people are employed at the firm?
3. Arrange 8 pennies in a row. The object of the game is to move the pennies one at a
time into an arrangement of four "stacks" of two pennies each. The restriction is that
whenever you move a penny, you must jump two other pennies. To describe your
answer, number the pennies from 1 to 8, and describe a move, for example, by "move
#1 on top of #4".
4. A monk leaves at 6:00 A. M., climbs a trail to the top of a mountain at
a variable rate of speed, and arrives at the summit at 6:00 P. M. He sleeps until 6:00
A. M., and begins his descent along the same trail, arriving at the bottom at 6:00 P. M.
Show that there is at least one place on the trail that he crosses at the same time of day
going up and coming down. The answer is not "halfway up the mountain"!

mph. Sixty minutes later Steve leaves in his car enroute from Philadelphia to New
York going 40 mph. When the two cars meet, which one is closer to New York?
7. A hunter left camp at 6:00 A. M. and traveled in a due south direction 5 miles,
where he saw a bear. The bear headed off due east, and the hunter tracked him for 5
miles, at which point he gave up, and then travelled due north 5 miles back to his
camp. What color was the bear?

14. If 3 hens lay 3 eggs in 3 days, how many eggs will 300 hens lay in 300 days?
15. Five students are sitting in a circle. Two pairs of students have the same color hair.
Those with the same hair color are not sitting next to each other. Celeste is on the
right side of Theresa and on the left side of Jane. Celeste has the same color hair as
Ruth. Jane has the same color hair as Alice. Identify the positions of the girls in the
circle.
16. A farmer has 25 calves. All but 19 die. How many does he have left?
17. A rope is tied around the equator of the earth, at the surface. A second rope is also
tied around the equator, directly above the first one at a distance of one foot from it.
(a) How much longer is the second rope than the first?
(You do not need to know the diameter of the earth to solve this problem)
(b) Do you find the answer surprising?
(c) Why or why not?
18. A car made a round trip between two cities at 50 mph. The next day, it made the
same trip at 60 mph going and 40 mph coming back.

market as possible. Corey has 3000 bananas, and needs to take her bananas to market
which is 1000 miles away. The only problem is that Corey can carry only 1000
bananas at any given time, and must eat 1 banana for every mile she walks. Corey
only needs to get to the market and not return. How many bananas can Corey get to
market?
