Remember: These are open-ended problems. There could be other solutions than the ones we are giving.

Number Theory

1. 9 tables and 12 stools

2. 144,000 in 24 hours; 1,008,000 a week

3. 137 + 173 = 310

4. The first choice would give him $36,465 at the beginning of the fifth year; the second choice would give him $43000.

5. $2700


Measurement

6. Depends on length of arm measurement. If the measurement is 17 ", then one cubit is 17 " and 100 cubits = 1700"

7. 4608 sq. ft. sides; 36,864 sq.ft top; 41,472 total

8. 12,276 sq. ft


Geometry

9. 38 faces

10. Ring 1 = 6; ring 2 = 12; ring 3 = 18; ring 4 = 24; 15 x 6 = 90

11. 16; 224


Patterns, Algebra, And Functions

12. Tiana at 51 minutes

13. 728 Legos

14. 45 nickels and 27 dimes


Data, Statistics, And Probability

15. 47 + 3 = 150

16. Check answers.

17. Check graphs for title, scale, labels, and accuracy.
Semester 1: Mean = 90.4, Median = 90, Range = 24, Mode = none
Semester 2: Mean = 94, Median = 95, Range = 15, Mode = 100
