	Gallons of water in a 3 mile pipe		2009-02-19
		From tim: I need to know how many gallons of water a 16" pipe that is 3 miles long holds? Answered by Penny Nom.
	A ten player schedule		2009-02-19
		From john: I HAVE 10 PLAYERS ONE GAME PER NITE FOR 10 WEEKS WHO PLAYS WHO FOR WEEK 1 THRU 10 THANK YOU Answered by Victoria West.
	Vertices, edges and faces		2009-02-19
		From Deb: I have been reading the responses you have to whether or not a cone and cylinder have edges, and whether a cone has a vertex. I have also found differing answers in different books and websites. Your idea that it depends why we want to call it a vertex or edge is interesting but does not help the students next year when they have a different teacher who tells them that whatever decision I make is wrong! It also doesn't help them when they do the provincial testing. Does anyone know if EQAO considers them vertices or edges? I want to know because textbooks and provincial tests often ask the students to count the number of faces, edges, and vertices or to describe a solid by using these, or to identify a solid that they have described. We need to have consistency in what we are teaching! Answered by Chris Fisher.
	Joggong in opposite directions		2009-02-19
		From Mallory: Emma and her mother jog along a mile-long circular path in opposite directions. They begin at the same place and time. Emma jogs at a pace of 4 mi/h, and her mother runs at 6 mi/h. In how many minutes will they meet? Answered by Robert Dawson.
	One vertex angle of a regular octagon is trisected		2009-02-19
		From Chelsy: Suppose one vertex angle of a regular octagon is trisected as shown in the figure. Each side of the octagon measures 4 units. Find the area of the shaded area. Answered by Robert Dawson.
	The volume of a cylinder		2009-02-18
		From jim: given the volume of a cylinder at 565m^3 and the height of 20m how do i calculate the cross section area in order to determine the compression strength of the cylinder Answered by Harley Weston.
	Implicit differentiation		2009-02-18
		From Sunny: Find slope of the tangent line to the curve 2(x^2+y^2)2=25(x^2–y^2) at (3,-1) Answered by Robert Dawson and Harley Weston.
	The substitution method		2009-02-18
		From Nicolette: I am working on linear programming problems that I need to solve pairs of linear equations for. I am confused and am not sure how to solve these problems! 5x+3y=7      y=x-3 How can i solve this using the substitution method? Answered by Penny Nom.
	A line parallel to a given line		2009-02-18
		From Lisa: I'm having a hard time understanding the concept of how to write an equation of the line containing the given points and parallel to the given line. Express the answer in the form of y=mx+b. (7,9); 2x+5y=4. i would appreciate it alot if someone can show ne how to do this. Thank you, Lisa Answered by Penny Nom.
	A dinner party		2009-02-18
		From will: You are serving 3 different entrees at a party. If 100 guests are having beef, 175 guests are having pasta, and 45 percent of the guests are having chicken how many guests are expected at this party? Answered by Penny Nom.
	More on cardinal numbers		2009-02-18
		From Justin: Hello again, I was just wondering that since the rules of Cantor's cardinal numbers in set theory do not apply to the infinity obtained by limits in calculus (ex. x->0, y=1/x=infinity), does that mean that this infinity is the largest quantity in both calculus and mathematics? Justin Answered by Robert Dawson.
	The area between the x-axis and a curve		2009-02-18
		From Lauren: This is from a homework question I can't figure out. Let R be the region in the fourth quadrant enclosed by the x-axis and the curve y= x^2 - 2kx, where k > 0. If the area of the region R is 36 then what is the value of k? Answered by Robert Dawson.
	Angle of depression		2009-02-18
		From Meeka: An aircraft flying at an altitude of 2000m is approaching an airport. If the angle of depression of the airport is 5 degrees, what is the distance from the plane to the airport measured along the ground? Round your answer to the nearest tenth of a kilometer. Answered by Robert Dawson.
	How can other infinites can be larger than each other?		2009-02-17
		From Justin: Hello again, I was just wondering even in the context of set theory, how can other infinites can be larger than each other, I thought infinity itself is the largest possible quantity? Justin Answered by Victoria West and Robert Dawson.
	More on infinity and Set Theory		2009-02-17
		From Justin: I greatly appreciate your help I was just wondering from your previous answer, why doesn't Cantor's cardinal numbers in set theory apply to the limit x->0, y=infinity? Justin Answered by Robert Dawson.
