On Monday, Brian counted 28 ducks and Cathy counted 15 ducks. On Tuesday, they counted 37 ducks altogether. How many more ducks did they count on
Monday than Tuesday?

6 ducks

Step-by-step explanation:

Monday, Brian counted 28 ducks and Cathy counted 15 ducks

                = 28+15 =43

Tuesday, they counted 37

Monday count - Tuesday count

43 - 37 =6

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.

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
