Please help me on this :(

300 & 200

Step-by-step explanation:

In the first slide, 45 is the "whole" and 15 percent is the "part." From there you cross mutiply and solve. You should end up with 300.

The same concept is appled in the second slide, just without the example to go from!

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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.
