3. 1 teacher per 10 students
4. 40 students : 4 teachers
5. 5 teachers per 40 students

Part A: Identify the unir rates and ratios that are equivalent.
Part B: Give another unit rate or ratio that is not on the list but equivalent to the ones from Part A. Explain why these are equivalent.

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
