The diagram shows nine identical squares inside a rectangle the length of the rectangle is 18cm work out the width of the rectangle

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

If 25% of y is 30, what is 60% of y?

Combine the information in the problem and the chart using the average balance method to solve the problem.
