November Solutions Remember: These are open-ended problems. There could be other solutions than the ones we are giving. Number Theory 1. Accept any sensible answer. 2. Many answers. Sample--3 bills, 1 gold dollar, 1 half dollar, 2 quarters, 1 dime, 2 nickels, 4 pennies. 3. 28 bags of each 4. 4 small and 8 large mugs 5. Whiteout = \$1.74/oz Nyquil = \$1.39/oz. Pepto Bismol = \$.96/oz. Scope = \$.66/oz. Evian = \$.17/oz. Ocean Spray = \$.08/oz. Snapple = \$.084/oz. Gatorade = \$.079/oz. Iced Tea = \$.07/oz. Gas = \$.01/oz. Measurement 6. 90 tons 7. 4 1/2 feet 8. Number 3 is the best choice. Geometry 9. Answers will vary. 10. Octagonal Prism; 16 balls of clay. 11. Cube = 3 Trianglular Prism = 4 Hexagonal prism = 3 Octangular Prism = 3 Pentagonal Prism = 4 No, even number of sides requires 2 colors for sides and base is 3rd color. Patterns, Algebra, And Functions 12. 15 games 13. 4 x 5; 5 x 6; 6 x 7; 7 x 8; 8 x 9 10th = 110 dots 14. 48 heads each day. Data, Statistics, And Probability 15. Possible answers could include a circle graph, bar graph, tally, and cumulative frequency chart. 16. Check graphs for scale, title, accuracy, and labels. 17. The probability of getting \$.41 is the same as the probability of getting four different coins: 1 penny, 1 nickel, 1 dime, and 1 quarter. The probability is 4/4 * 3/4 * 2/4 * 1/4 = 24/256 = 3/32 HOW DID YOU DO?   November Problems Back to Open-Ended Math Index
