The student to teacher ratio at Finch Middle School is 17:1.

If there are 1,476 students and teachers combined at Finch Middle School, how many teachers are there?

Show or explain how you arrived at your answer.

82

Step-by-step explanation:

For a total (teacher and students) of 17 + 1 = 18, there is one teacher.

We have to find out how many teachers are there in 1476.

Set up the proportion : Number of teachers / Total number (of teachers and students)

Number of teachers / 1476 = 1 / 18

Number of teachers x 18 = 1476 x 1 = 1476

Number of teachers = 1476 / 18 = 82

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.
