Answer 1

9514 1404 393

Answer:

1. 4.00 feet
2. 48 inches
3. 8 pictures
4. 4 pictures

Explanation:

1. The available wall space is the difference between the length of the wall and the length of the window:

9.75 ft - 5.75 ft = 4.00 feet

__

2. At 12 inches per foot, this is ...

(4 ft)(12 in/ft) = 48 in

__

3. If the pictures are 6 inches wide, Mr. Smith can use ...

(48 in)/(6 in/picture) = 8 pictures

__

4. If the pictures are 10 inches wide, Mr. Smith can use ...

(48 in)/(10 in/picture) = 4.8 pictures

There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.
