1. Mr. Brown went grocery shopping to buy meat for his annual office picnic. He bought 7 ¾ pounds of hamburger, 17.85 pounds of chicken, and 6 ½ pounds of steak. How many pounds of meat did Mr. Brown buy?a) 21.10 b) 22.10 c) 26.25d) 31.31 e) 32.10|6. The diagram (right) shows a pasture which is fenced in. All but one section of fence runs straight north-south or east-west. Consecutive fence posts are 10 feet apart except for the one diagonal section. Which of the following statements best describes P, the perimeter of the pasture, in feet?a) P > 210b) P = 210c) P < 210d) P > 230e) P = 240|
2. When getting into shape by exercising , the subject’s maximum recommended number of heartbeats per minute (h) can be determined by subracting the subject’s age (a) from 220 and then taking 75% of that value. This relation is expressed by which of the following formulas?a) h = .75(220 – a) b) h = .75 (220) – a c) h = 220 - .75a d) 75h = 220 – a e) 220 = .75(h –a)|7. Let d = st be the formula for distance, where d represents distance traveled in miles; s, speed in miles per hour; and t, time elapsed in hours. If the distance traveled is 15 miles and the time elapsed is 45 minutes, what is the speed in miles per hour?a) 11.25b) 12c) 18.75d) 20e) 30|
3. Which of the following is equivalent to 3a + 4b – (-6a – 3b)?a) 16abb) –3a + bc) –3a + 7bd) 9a + be) 9a + 7b|8. A rectangular box with a base 2 inches x 6 inches is 10 inches tall and holds 12 ounces of breakfast cereal. The manufacturer wants to use a new box with a bas 3 inches x 5 inches. How many inches tall should the new box be in order to hold exactly the same volume as the original box? (Note: the volume of a rectangular box may be calculated by multiplying the area of the base by the height of the box.)a) 8b) 9c) 10d) 11e) 12|
4. For all y and all N, (y2 – Ny + 4) + (y2 – 2) =a)
