On saturday alison used her cell phone for 36 minutes. on sunday she used he cell phone for 18 minutes more than saturday find the ratio of the number of minutes alison used on saturday to the total number of minutes onn saturday and sunday give your answer in simplest form

Step-by-step explanation:

On Saturday Alison used her cell phone for 36 minutes.

On Sunday she used he cell phone for 18 minutes more than Saturday, i.e 36+18= 54 minutes.

In total she used 54+36= 90 minutes on Saturday and Sunday.

So,

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.
