A homeowner's backyard is a rectangle with width 18 yards long and length 16 yards long. They plan to put in a square pool with

Ugo [173]

Answer:

Step-by-step explanation:

Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;

Area of rectangle = Length * Width

Area of the rectangular backyard = 18yards * 16yards

Area of the rectangular backyard = 288yards²

If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²

The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool

The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²

Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use. The area needed for the tiles for the rest of the backyard is therefore 263yd².

Amount of tiles needed to buy can be expressed as 263/dimension of a tile.

Is quadrilateral JKLM the result of a dilation of quadrilateral ABCD by a scale factor of 2? Why or why not? Yes, because sides

scZoUnD [109]

I'm taking this pre-test right now. I think the answer is "No, because sides JM and KL have different slopes from sides AD and BC."
After looking closely, it looks like JM and KL are slightly steeper lines than AD and BC.

of 36 chemical elements 2 are named for woman scientists and 25 are named for places what fraction out of these 36 are named for

vova2212 [387]

Answer:

27/36, or simplified, 3/4

Step-by-step explanation:

You add the number of elements named after woman scientists to the number of elements named after places: 2+25 = 27.

That is 27 out of the 36, so you put 27 over 36 in a fraction. $\frac{27}{36}$

To simplify, divide both 27 and 36 by 9.

27 ÷ 9 = 3;

36 ÷ 9 =4;

Simplified answer is 3/4
