Solution:
8 hours.
Graphical Solution:
Extend both lines to the right until they intersect. Then read the horizontal coordinate of the point of intersection.

Note: If lines are extended correctly until they intersect, this will serve as sufficient justification. No words are required in this situation.

This question could be solved using either a numerical, graphical, or algebraic approach. Whatever solution path was selected required the student to recognize that the water in tank T is decreasing at a rate of 50 gallons per hour and the water in tank W is increasing at a rate of 25 gallons per hour. These rates could be used to determine when there are equal amounts of water in the two tanks by using any one of several methods, for example, by numerically comparing values for the amount of water in the tanks at different times, by extending the given graphs until they intersect, or by setting up and solving an equation.

Question 20

Scoring Guide

Solution:

Scoring Guide

In this question a student needed to demonstrate an understanding of diagonals of polygons. A diagonal of a polygon is a segment that joins two nonadjacent vertices.(A vertex is a common endpoint of two sides of the polygon). To answer the question it was expected that a student would observe that the number of diagonals from any vertex is 3 less than the number of sides. That is, from any vertex of a convex polygon a diagonal can be drawn to any of the other vertices of that polygon except the two adjacent vertices. For a 20-sided polygon, the answer is 20 - 3 = 17.

There are different types of incorrect responses. If a student overestimated the perimeter as between 7 and 8, then a score of incorrect # 3 is earned. If a student underestimated the perimeter as between 5 and 6, then a score of incorrect # 2 is earned. Any other response is an incorrect # 1.

Question 27

Scoring Guide

Solution:

An adequate explanation with or without Bob.
May say "neither" or "both".

Parts of P overlaps N, and part sticks out. The sticking out part is equal to the left out part of N.

Two P's match two N's therefore they have the same area. (Therefore, one N has the same area as one P.)

Areas are equal because height of P is the same as the height of N, and the base of P is twice the base of N.

Either of these two figures alone are acceptable.

Scoring Guide

In this question, a student has to compare two given shapes with respect to their area. A student needed to realize that area meant the amount of surface a shape covers. They also needed to know how to compare the areas of the shapes. Using pictures and words to make the comparison between the areas of N and P, a student could have given a variety of explanations such as two shape P's match with two shape N's; therefore, one N has the same area as one P. They also could have used the geometric shapes placed one on top of the other to see how their areas compared.

Question 30

Scoring Guide

Solution:
1571

Scoring Guide

In this question, a student needed to interpret that the lowest point of the St. Lawrence River is a negative number and the highest point of Mt. Jacques Cartier is a positive number (both with respect to sea level). To find the difference between the highest point and the lowest point and to earn full credit, a student needed to subtract the two numbers. To earn partial credit, a student would have had to show the correct procedure using positive and negative numbers, but made a computation error.

Score & Description

	Correct
	Correct response

	Partial
	Shows correct procedure (addition) but does not answer 1571. Correct procedure means either 1277-(-294) or 1277 + 294, but not 1277 - 294.

Question 31

Scoring Guide

Solution:
Brian (constant difference)

Scoring Guide

In this question, a student has to use mathematical reasoning to construct different justifications that support Darlene’s and Brian’s claims. In this real-world problem, students have to construct an appropriate method for supporting each claim in the question. One such method uses proportional thinking as well as percentages to explain how a conclusion could be reached, while the other involves comparing differences in growth by subtraction. Partial credit is earned if a student just gives a correct justification for Brian’s or Darlene’s claim, but not both, or shows a limited understanding of how to proceed with the problem.

Score & Description

In this question, a student needed to use proportional thinking to solve this problem. The student should have reasoned that both Victor’s rate and Sharon’s rate are equal. To earn full credit the student needed to answer both parts of the question correctly with the correct justification for each. To earn partial credit, a student could have just answered one part correctly with the correct justification or answered both parts with no justification or incorrect justifications.
