  1. NeSAm 8th

  2. 1A Use the table to answer the question. Rounding to the nearest dollar, which shows how to estimate the cost of purchasing five sport balls, one of each type? • $31.00 = $4 + $1 + $12 + $8 + $6 • $32.00 = $5 + $1 + $12 + $8 + $6 • $34.00 = $5 + $1 + $13 + $9 + $6 • $36.00 = $5 + $2 + $13 + $9 + $7

  3. 1B In 1993, a group in Utica, New York, made a very large round jelly doughnut which broke the world record for doughnut size. It weighed 1.5 tons and had a circumference of 50 feet. Estimate the diameter of the doughnut. About 17 feet

  4. 1C Sound travels 1129 feet per second through air. Estimate how far sound can travel in 2 seconds when traveling through air. ≈ 2000 feet

  5. 2A Marty has $80 to spend at a sporting goods store. He will spend $56 on a shirt, and then buy some darts. Each box of darts costs $6. He wants to buy as many boxes as possible. Write an equation to show the number of boxes of darts, x, he can buy. 80 = 56 + 6x

  6. 2B Joshua burns 4.5 Calories per minute pushing a lawn mower. Write an equation representing the number of Calories C burned if Joshua pushes the lawn mower for m minutes. C = 4.5m

  7. 2C Ava has $65 to spend at the mall. She bought a T-shirt for $18 and a belt for $14. She still wants to buy a pair of jeans. Write an inequality to show how much she can spend on jeans. 18 + 14 + x ≤ 65

  11. 4A Use the figure to answer the question.

  12. 4B Use the figure to answer the question. Which statement is true? A. 1 and 2 are complementary angles B. 3 and 6 are vertical angles C. 7 and 8 are adjacent angles D. 2 and 3 are supplementary angles

  13. 4C Use the figure to answer the question. Which statement is true? A. 6 and 7 are complementary angles B. 2 and 5 are vertical angles C. 7 and 6 are adjacent angles D. 5 and 7 are supplementary angles

  14. 5A Write an expression for four less than twice a number n. 2n - 4

  15. 5B Write an expression for twice the sum of x and 3. 2(x + 3)

  16. 5C Write an expression for six times x plus the sum of eight times y and twice x. 6x + (8y + 2x)

  17. 6A Use the table to answer the question. The table shows Katelyn’s bowling scores for a four-week time period. Her mean bowling score for the four weeks was 136. She bowled 126 the fifth week. What will be the change from the 4-week to the 5-week mean? decrease by 2

  18. 6B Use the table to answer the question. The table shows Katelyn’s bowling scores for a four-week time period. Her mean bowling score for the four weeks was 136. What would she need to score on the fifth week to raise her mean score to 140? 156

  19. 6C Use the table to answer the question. The table shows Katelyn’s bowling scores for a four-week time period. Her mean bowling score for the four weeks was 136. If she scored 131 the fifth week what would her new mean be? 135

  20. 7A Use the graph and table to answer the question. The circle graph show the percent of students involved in each activity. The table shows the number of students in each activity. Which statement is caused by a misrepresentation of data in the circle graph? • Students are involved in clubs the least. • Students are involved in music the most. • Students are involved in three activities. • Students are involved in 180 percent of the activities.

  21. 7B Use the graph below to answer the question. What is wrong with this circle graph? The sum of the percents is 100, which is correct. However, 30% and 20% appear to be the same size. 30% needs to be represented by a larger sector than 20%.

  22. 7C Which statement is caused by a misrepresentation of data in the box-and-whisker plot? • The median of Data A is greater than the median of Data B. • Data B has an outlier at 13. • The Data B has a greater interquartile range than Data A. • Both sets of data end the 1st quartile at 5.
