• Q: What do you get if you divide the
cirucmference of a jack-o-lantern by its
diameter?
• A: Pumpkin Pi!
For a regular pentagonal
prism, what is the ratio of
the number of vertices to the
number of edges?
A rhombus is shown below
• If the height, h, intersects the
base at its midpoint, what is the
height of the rhombus?
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’?
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?
For any negative integers m, n,
p and q, which of the following
is always true if mn < pq?
A. q > m
B. -mn > -pq
C. -n < -p
D. nq < mp
What is the solution set for the
equation 2x2 - 16x
- 96 = 0?
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?
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?
Triangle XYZ is shown below.
What is the length of XY?
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?
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.
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!"
