Can you completely over a 4 ft by 8 ft area with 3 ft by 3 ft tiles?
Vika [28.1K]

Yes, but not without cutting some of the tiles into smaller pieces.

The length of the area is 8-ft.  That's (2 and 2/3) tiles long.

The width of the area is 4-ft.  That's (1 and 1/3) tiles wide.

So you can't just put down rows and columns of whole tiles
and cover the whole area.
______________________________________

Another way to look at it:

-- The area of the whole big plot is  (8 x 4) = 32 square feet.

-- Each tile covers (3 x 3) = 9 square feet.

-- You can't cover 32 square feet with 9-square-feet pieces.
Either you have to cut something off, or else you have to let
something hang outside of the lines.

The sum of three consecutive even numbers is 66. What is the smallest of these numbers?
ahrayia [7]
Your answer would be 22 because it says <em>"sum"</em> which means <u>add.</u> Then it says "<em>of three consecutive <u>even</u> numbers</em>" which means you're going to be adding <u>three</u> of the <em>same <u>even</u> number </em>to get 66. 22 is an <u>even</u> number, so let's try it out: 22 + 22 + 22 = 66. (You can also divide 66 by 3.) 22 is the cOrrect answer.

Hope this helps,

An=-31+(n-1)-11 find the eleventh term

a11 = -31 + (-11) (11-1)

a11 = -31 +-11(10)

a11 =-31 +-110
