#14 A scale drawing of a rectangular room measures 2 cm by 4 and 1/4 cm. E The scale used for the scale drawing is 1/2 cm = 5 ft. Carpeting will cost
$8.50 a square foot. How much will it cost to buy enough carpet to cover
the floor of this rectangular room? (**numbers and decimal only in answer
** NO $$ NO comma**) *

Step-by-step explanation:

Width

1/2 cm = 5 feet

2cm = x                    Cross Multiply

1/2 x = 2 * 5              Combine

1/2 x = 10                  Multiply both sides by 2

x = 20

Length

1/2 cm = 5 feet

4 1/4 cm = x              Cross Multiply

1/2 x = 4 1/4 * 5         Combine the right

1/2 x = 21.25              Multiply both sides by 2

x = 42.5                    

Room Area

Area = 20 * 42.5

Area = 850 square feet

Cost

1 square foot costs 8.5 dollars.

850 square feet costs 8.5 * 850

850 square feet costs 7225  dollars.

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)
