Answer:

  244 tiles

Step-by-step explanation:

These "border" problems can be a little tricky.

The tiles are 1 ft square, so an integer number of them fit along each of the sides. The 40-ft side will take 40 tiles for its border, and the 80-ft side will take 80 tiles.

The total number of tiles along each of the four sides is ...

  40 + 80 + 40 + 80 = 240 . . . tiles

However, there is also a tile in each of the corners. There are 4 of those, so the total number of tiles surrounding the pool is ...

  240 +4 = 244 tiles

__

<em>Alternate solution</em>

For a border of width w, the outside area of the pool plus the border is ...

  A = LW = (80 +2w)(40 +2w) = 80·40 +240w +4w²

The area of the pool is ...

  A = LW = (80)(40) = 80·40

Subtracting the area of the pool from the total area including the border gives ...

  border area = (80·40 +240w +4w²) -(80·40) = 240w +4w²

We know the width of the border is 1 foot, so w=1 and the border area is ...

  border area = 240·1 +4·1² = 244 . . . . square feet

Each tile is 1 square foot, so 244 tiles are needed for the border.

_____

It can help to draw yourself a diagram. It can also help to make a small model using blocks, Scrabble tiles, Legos, jigsaw puzzle pieces, squares cut from paper, or even coins (pennies). Anything that will give you an idea of how to count the tiles required to make a border can be helpful.

lidiya [134]

Answer:

<u>All the four statements are true , which are -</u>

(A) The subset contains contains of all the outfits that have grey slacks .

(B)  The subset contains contains of all the outfits that have grey slacks and red tie .

(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .

(D)  The subset contains contains of all the outfits that do not have black slacks .

Step-by-step explanation:

<u>We are given with Outfit 2 , 4 and 6</u>

Outfit 2 -   Blue     grey     red

Outfit 4 -   White    grey     red

Outfit 6   - Black     grey    red

(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .

(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .

(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .

(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.

Hence , all the options A , B , C , D are correct and describes the subset .
