Monica is making a design in art class. She is experimenting with how to transform line segment AB in her design. If she reflects the line segment across line l, how will the length and position of segment AB and its image compare?

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
