The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long

Fynjy0 [20]

Find the total area of the room
109 * 103 = 11227 inches^2
the tile takes up 3*3 = 9 inches^2
11227/9 = 1247.4
You need 1247 tiles and 0.4 of a tile.
Or you could just get 1248 and cut the last tile a bit :P

Hope this helps :)

Find the slope of the line that would pass

Leno4ka [110]

Answer:

Step-by-step explanation:

Here we go!

Slope Formula:

$\frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} }$

What we know: (-4, -52) and (-1, -22)

Plug in the numbers!

$\frac{ - 52 - ( - 22)}{ - 4 - ( - 1)}$

Fix it!

$\frac{ - 52 + 22}{ - 4 + 1}$

Add

$\frac{ - 30}{ - 3}$

Divide

(negative divided by a negative is a positive!!)

Slope is 10

Hope this helps!

Which relationship is a direct variation?

Setler79 [48]

Option A is the relationship which shows a direct variation.

Step-by-step explanation:

The direct variation is a relationship between two variables in which one is the multiple of the other. It is given by the relation

$\frac{y}{x}=k$

Option A:

For $x=2$ and $y=1$ ,

$\frac{y}{x}=\frac{1}{2}$

For $x=4$ and $y=2$ ,

$\frac{y}{x}=\frac{2}{4}= \frac{1}{2}$

Since, the constant k is equal for all the values of x and y in the table, this relationship is a direct variation.

Option B:

For $x=2$ and $y=4$ ,

$\frac{y}{x}=\frac{4}{2}= 2$

For $x=4$ and $y=16$ ,

$\frac{y}{x}=\frac{16}{4} =4$

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Option C:

For $x=1$ and $y=3$

$\frac{y}{x} =\frac{3}{1} =3$

For $x=2$ and $y=5$

$\frac{y}{x} =\frac{5}{2}$

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Option D:

For $x=1$ and $y=-1$

$\frac{y}{x} =\frac{-1}{1} =-1$

For $x=2$ and $y=2$

$\frac{y}{x} =\frac{2}{2} =1$

Since, the values of constant k is not equal for all the values of x and y in the table, this relationship is not a direct variation.

Thus, Option A is the relationship which shows direct variation.
