Answer:

$415.0575

Step-by-step explanation:

Given:

Scale measurement

1 inch = 3 feet.

In the drawing, the length is 5.5 inches and the width is 3.25 inches.

Length = 5.5 × 3

= 16.5 feet

Width = 3.25 × 3

= 9.75 feet

Area of the bedroom = length × width

= 16.5 feet × 9.75 feet

= 160.875 square feet

carpets cost $2.58 per square foot

Cost of carpeting the bedroom = Area of the bedroom × cost of carpet per square foot

= 160.875 × 2.58

= $415.0575

Cost of carpeting the bedroom = $415.0575

irina [24]

Answer:

New bed dimension of bed 0.5 ft, 0.25 ft

New bed dimension of room 1.16 ft, 1.33 ft

Step-by-step explanation:

Given data:

bed dimension is given as 6 ft by 3 ft

room dimension is given as 14 ft 16 ft

according to the given information , new dimension of the room and bed will be 1/12 times of actual dimension. therefore we have

New bed dimension of bed = \frac{1}{12} \times 6 ft, \frac{1}{12} \times 3 ft

                                 = 0.5 ft, 0.25 ft

New bed dimension of room = \frac{1}{12} \times 14 ft, \frac{1}{12} \times 16 ft

                                                 = 1.16 ft, 1.33 ft

If 2a-b:2a+b=1:2find the value of a:b​
weqwewe [10]

Answer & Step-by-step explanation:

2a - b : 2a + b = 1 : 2

2a - b = 1

-                         Elimination

2a + b = 2

-b - (b) = -1

-2b = -1

b = 0.5

---------------------------------------------------------------------------------

2a + b = 2           Substitution

2a + 0.5 = 2

2a = 1.5

a = 0.75

--------------------------------------------------------------------------------------

a:b

0.75 : 0.5

or

3/4 : 1/2

Hope this helps!!!
