Joan performed an experiment on two different types of cells and noted their sizes as follows: Cells Size
Cell A 0.0005×10−5 m
Cell B 0.0025×10−7 m
What is the ratio of the size of cell A to the size of cell B?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
