What is the smallest counting number more that 100 and a multiple of 9?

  108

Step-by-step explanation:

A number is divisible by 9 when its sum of digits is divisible by 9. Hence you're looking to add a digit to the digit 1 that makes the total be 9. That digit is 8.

When you put 8 in the units place of the number with 1 in the hundreds place, you get the smallest number greater than 100 that is divisible by 9: 108.

45

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.
