A school survey says that 75% or 294 of the 8th graders have cell phones how many 8th graders are there?

75

x 294 = 220.5 around 221 students.

100

The keyword of means multiplication.

Consider a percent out of 100.

A way to remember is that: "cent" means 100.

what grade level is this? need to know so i can look in my old textbooks!

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.
