Tyler is laying tile on his rectangular kitchen floor. The dimensions of the floor are 16 1/2 feet by 15 feet. If he is using sq
blondinia [14]
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.

Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.

Which set of numbers could be the length of the sides
Svetllana [295]

Answer: Choice C)  {6, 9, 12}

=======================================================

Explanation:

Something like choice A can't form a triangle because the first two sides add to 6+9 = 15, which is <u>not</u> longer than the third side 15. We need to have x+y > z to be true. The same goes for choice B as well because 3+3 = 6 is too small compared to the third side 7. Choice D is similar to choice A.

In short, we can rule out choices A, B, and D.

The only thing left is choice C. Picking any two sides leads to having that sum be larger than the third side

  • 6+9 = 15 which is larger than 12
  • 9+15 = 24 which is larger than 6
  • 6+15 = 21 which is larger than 9

So the conditions of the triangle inequality theorem work out here, and we have a triangle.
