Apprenticeship and workplace Math 11 St.John Brebeuf Example 1: Charlene is working on a project in her Art Metal class. She wants to make a brass cookbook holder like the one in the diagram. She does not have a protractor to measure the angle, but the diagram is drawn on graph paper. What is the slope of the cookbook holder a) as a simplified fraction b) as a decimal Solution: Example 2: Duncan and Casey are using hand trucks to move small boxes from a house to a garage. They lay a loading ramp against the house steps which are 18’’ high. The slope of the steps is 0.2. What is the horizontal distance in feet from the base of the ramp to the point x . S.Duffy Page 2
