A rectangular garden is 10 feet long and 5 feet wide. A second rectangular garden has dimensions that are 9/8 the dimensions of the first garden. What is the percent of change in the perimeter from the first garden to the second garden?

The answer to your question is  12.5 %

Step-by-step explanation:

Data

length = 10 ft

width = 5 ft

Proportion 9/8

Process

1.- Calculate the perimeter of the original rectangle

Perimeter 1 = 2l + 2w

-Substitution

                   = 2(10) + 2(5)

                   = 20 + 10

                   = 30 ft

2.- Calculate the dimensions of the second rectangle

length = 9/8 (10) = 90/8 = 45/4

width = 9/8 (5) = 45/8

3.- Calculate the perimeter of the second rectangle

Perimeter 2 = 2(45/4) + 2(45/8)

                    = 22.5 + 11.25

                    = 33.75 ft

4.- Calculate the percent of change

                     30 ft 100%

                     33.75 ft x

                     x = (33.75 x 100) / 30

                     x = 3375/30

                     x = 112.5

Change = 112.5 - 100

Result

             = 12.5 %

it would take 7/10 of an hour too fill the pool.

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.
