1. An 10-inch-by-11-inch transparency sheet is placed on an overhead projector. If the projector enlarges 300%, what will be the lengths of the sides of the projection? How does the perimeter of the original transparency sheet compare to the perimeter of the projection? 2. Determine whether the circles in the diagram below are concentric. Explain your reasoning. 3. In OM, chords OR and ST intersect at U. Determine TU if QU = 6, RU = 9, and SU = 7. O 4. Add the two matrices below. 5. On a floor plan, a porch in the shape of a trapezoid has an area of 2.5 square feet. If the floor plan has a scale of 1 : 15, what will be the actual area, in square feet, of the porch when it is built? 6. The diagram below shows the first two iterations of a fractional pattern. Draw the third iteration. ORIGINAL 1 ST ITERATION 2 ITERATION
