  1. Stanford 9 • On a piece of paper, make an answer sheet from 1 to 30.

  2. Stanford 9 • You must show all your work on the answer sheet. I will collect these at the end of the period.

  3. Stanford 9 1.) In the equation t = d/6 + 3 what is the value of t when d = 12? 2.) A cable crew had 120 feet of cable left on a 1000-foot spool after wiring 4 identical new homes. If the spool was full before the homes were wired, which equation could be used to find the length of cable (s) used in each home?

  4. Stanford 9 3.) What is the solution for 2t < 5 ? 4.) A certain bank balance b is given by b = 100 + d - w where d is the deposits and w is withdrawals. What is the balance when d = 100 and w = 125 ?

  6. Stanford 9 6.) For each trip, a taxicab company charges a flat rate of $2.00 and $.0,25 for each ¼ mile traveled. The graph shows a customer’s total fare. Which graph shows a customer’stotal fare for a different companythat charges a flat rate of $1.50

  7. Stanford 9 X Y -2 1 -1 3 0 5 1 7 2 9 7.) The table of ordered pairsshows the coordinates of some points on the graphof a function. Whichequation describes a function that contains all the points shown in the table?

  8. Stanford 9 8 • 8.) The dimensions of a flap on a scale model of an airplane are shown below. On the actualflap, if y = 60 inches,what is the measureof x? 2 60 x

  9. Stanford 9 • 9.) In the triangle shown below, angles A and B have the same measure. What is the measure of angle A? 104 A B

  10. Stanford 9 • 10.) The square shown below has 4-foot sides. What is the approximate area of the inscribed circle? (Use Area = r2and  = 3.14) 4 A B C D

  11. Stanford 9 • 11.) An artist plans to paint a triangle on a rectangular wall as shown below. If it takes one gallon of paint to cover the whole wall, how much paint is needed for the triangle? 25 16

  13. Standford 9 14.) A point is moved from P to Q as shown. If a point at (-1,1) is moved in the same way, what will be its new coordinates? Y P Q X

  14. Stanford 9 • 15.) Which is the closest to the sine ratio of a 250 angle? • 16.) A cable 40 feet in length is stretched to the ground from the top of a pole that is 20 feet high and perpendicular to the ground. Which is closest to N, the measure of the angle the cable makeswith the ground. 40 20 N

  16. Stanford 9 • 18.) A six-sided game piece has either a vowel or a consonant written on each face. When the game piece is rolled, there is a 1/3 probability that a vowel will show on the top face and a 2/3 probability that a consonant will show on the top face.When the game piece is rolled 1000 times, about how many will a vowel probably show on the top face.

  17. Stanford 9 • 19.) the table shows the probability of each possible outcome when three coins are flipped at the same time.If the coins are flipped 48 times, how many times would all three coins probably show tails at the same time?

  18. Stanford 9 • 20.) What is the probability that a man chosen at random will be taller than 73 inches? • 21.) a 3-digit code that contains both letters and numerals can be converted to a whole number in the decimal system. Use the steps in the packet to decode Y5Z.

  19. Stanford 9 • 22.) On a lunch special there are 2 choices for soup, 3 choices for salad, 4 choices for the main course, and 3 choices for drinks. How many different meals consisting of 1 soup, 1 salad, 1 main course, and 1 drink can be ordered?

  20. Stanford 9 • 23.) the sum (S) of the areas of all the squares in the infinite squence can be found by the formula s = a/(1-r).Where a is the area of the first square and r is the common ratio. What is the sum of the areas of all the squares in the pattern? common ratio is 1/2 A = 1 A=1/2 A = 1/4 A=1/8

  21. Stanford 9 • 24.) Use the graph in the packet and determine which is the best estimate of the number of square units in the shaded area? • 25.) If the perimeter of one is 2 units, which figure has a perimeter of 5 units?
