Markio has 80:1 scale-drawing if the floor plan of her house. On the floor plan the dimensions of her rectangular living room 1 7/8 inches by 2 1/2 inches. What is the area of her real living room in square feet

208 1/3 ft squared

Step-by-step explanation:

   The dimensions of the real living room in inches are

                              80 x 1 7/8= 150

                              80 x 2 1/2= 200

The area of the living room is

                              150in x 200in= 30,000in squared.

   To convert square inches to square feet,

   you have to divide by 12 squared = 144

                               30,000 / 144= 208 1/3

 So the area of the living room is 208 1/3 squared

                             Finding the area:

The area of the living room in the floor plan is

                                1 7/8in x 2 1/2 in= 75/16 in squared

Since the lengths scaled by 80, the area scales by 80 squared. The area of the real living room in squared inches is 75/16 x 80square= 30,000

To convert square inches to square feet,

you have to divide by 12 square = 144

                           30,000/144= 208 1/3

THE AREA OF THE LIVING ROOM IS 208 1/3 ft squared

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
