howard and claudi are placing square carpeting tiles in a wide hallway in the theater. The tiles one one side hace 16 inch sides and the tiles on the other side have 24 inche sides.
A.how many of each tile will they have to buy for a 12 foot long hallway?
B.how many times will edges of each kind of tile line up?
answer a and b please.
A, wouldn't the numbers of tiles depend on how wide the hallways is?
1-3/4
1/1-3/4
3/4

Matter is anything that takes up space and has mass.A few examples are paper, balls, pencil and even you! Sevral properties or traits must be used together to adequately describe a type of matter.
To find the number of tiles they will need to buy for a 12-foot long hallway, we first need to convert the length from feet to inches.
Since there are 12 inches in a foot, a 12-foot long hallway is equal to 12 * 12 = 144 inches.
Now, let's calculate the number of 16-inch tiles they will need. To cover a length of 144 inches using 16-inch tiles, we divide the total length by the side length of the 16-inch tile:
Number of 16-inch tiles = 144 inches / 16 inches = 9 tiles.
Similarly, let's calculate the number of 24-inch tiles they will need. To cover a length of 144 inches using 24-inch tiles, we divide the total length by the side length of the 24-inch tile:
Number of 24-inch tiles = 144 inches / 24 inches = 6 tiles.
Therefore, they will need to buy 9 tiles of the 16-inch size and 6 tiles of the 24-inch size to cover the 12-foot long hallway.
Now, let's move on to part B of the question, which asks how many times the edges of each kind of tile will line up.
Since the 16-inch tiles have sides of 16 inches, each tile will have three exposed edges, as they would be touching other tiles on two sides. Therefore, the edges of the 16-inch tiles will line up 9 tiles * 3 edges per tile = 27 times.
Similarly, since the 24-inch tiles have sides of 24 inches, each tile will also have three exposed edges. Therefore, the edges of the 24-inch tiles will line up 6 tiles * 3 edges per tile = 18 times.
To summarize:
A. They need to buy 9 tiles of the 16-inch size and 6 tiles of the 24-inch size.
B. The edges of the 16-inch tiles will line up 27 times, and the edges of the 24-inch tiles will line up 18 times.
