  1. Q: What do you get if you divide the cirucmference of a jack-o-lantern by its diameter? • A: Pumpkin Pi!

  2. For a regular pentagonal prism, what is the ratio of the number of vertices to the number of edges?

  3. A rhombus is shown below • If the height, h, intersects the base at its midpoint, what is the height of the rhombus?

  4. ABC has vertices A (-2,5), B(-2,2), and C (-5,2). If ABC is reflected across the line y = x, which of the following will be the coordinates of A’?

  5. Each square design below is made up of rectangles of equal size. Each rectangle is twice as long as it is wide. If this pattern continues, what would be the length of the next square design. How many rectangles would be needed to build the design?

  6. For any negative integers m, n, p and q, which of the following is always true if mn< pq? q > m -mn > -pq -n < -p nq< mp

  7. What is the solution set for the equation 2x2 - 16x- 96 = 0?

  8. Michelle’s cellular-phone company offers a plan that allows 300 minutes of use for $29.95 per month and charges $0.19 for each additional minute. All prices include tax and fees. Michelle has budgeted $50 per month for calls on her cellular phone. What is the maximum number of minutes that she can use her cellular phone each month without spending more than $50?

  9. The function below shows a relationship between x and y. y = 7x + 3 If the value of x increases by 1, what happens to the value of y?

  10. Triangle XYZ is shown below. What is the length of XY?

  11. Dominique created a pattern using right triangles. She started the pattern with an isosceles right triangle, with each leg measuring 1 unit. The hypotenuse of each successive triangle follows a pattern, as shown in the diagram below. If Dominique continues this pattern 5 more times, what is the measure of the final hypotenuse?

  12. In Figure 1 a cylinder with a diameter of 12 centimeters is filled with water to a height of 8 centimeters. In Figure 2 a rock is submerged in the cylinder. What is a good estimate of the value of the rock? Explain how you solved this problem.

  13. A mathematician is flying non-stop from Edmonton to Frankfurt with AirTransat. The scheduled flying time is nine hours. Some time after taking off, the pilot announces that one engine had to be turned off due to mechanical failure: "Don't worry - we're safe. The only noticeable effect this will have for us is that our total flying time will be ten hours instead of nine." A few hours into the flight, the pilot informs the passengers that another engine had to be turned off due to mechanical failure: "But don't worry - we're still safe. Only our flying time will go up to twelve hours." Some time later, a third engine fails and has to be turned off. But the pilot reassures the passengers: "Don't worry - even with one engine, we're still perfectly safe. It just means that it will take sixteen hours total for this plane to arrive in Frankfurt." The mathematician remarks to his fellow passengers: "If the last engine breaks down, too, then we'll be in the air for twenty-four hours altogether!"
