Q. Your visually impaired friend asked you to enlarge your notes from class so he can study. You took notes on 8.58.5 inch by 1111 inches paper. The enlarged copy has a smaller width of 1010 inches. What is the scale factor of this dilation?
  1. Identify Widths: Step 11: Identify the original width and the enlarged width.\newlineOriginal width = 8.58.5 inches.\newlineEnlarged width = 1010 inches.
  2. Calculate Scale Factor: Step 22: Calculate the scale factor by dividing the enlarged width by the original width.\newlineScale factor = Enlarged width / Original width = 10 inches8.5 inches=1.1764705882352942\frac{10 \text{ inches}}{8.5 \text{ inches}} = 1.1764705882352942.
