Andy is hanging wallpaper in his kitchen. He is able to cover of the walls in the room using 6 rolls of wallpaper. What is the n

Alchen [17]

Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.

To Find:

Number of rolls used per wall.

Solution:

Since, we know that the shape of a kitchen is a cuboid.

And a cuboid has total 6 faces, with 4 walls, one roof and one floor.

So, total number of walls in Andy's kitchen = 4

Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.

In order to find the number of rolls used per wall, we'll have to divide the total number of rolls used with the total number of walls.

Number of rolls used per wall =

So, 1.5 rolls are used to cover one wall.

Solve for x<br> x^9=12^2x12^7

jekas [21]

Answer:

Step-by-step explanation:

Hi!

Here is your answer,

I will explain in step by step,

${x}^{9} = {12}^{2} \times {12}^{7}$

Here we can simplify this further using this law,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

So we will get,

${x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9}$

Since the powers are same we can cancel it out and we will get,

$x = 12$

(Hope this answer helped :))

A circle has a radius of 7/4 units and is centered at <br> (−2.5,−4.4)

lana66690 [7]

Are you asking for the expression?

If so, you plug into the format (x - h)² + (y - k)² = r² where (h, k) is the center and r is the radius.

(x + 2.5)² + (y + 4.4)² = (7/4)²

Simplify to get your equation and answer:

(x + 2.5)² + (y + 4.4)² = 49/16
