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.

Find the value of y.

ch4aika [34]

Answer:

$\Huge\boxed{B.18.610}$

Step-by-step explanation:

Hello There!

We can find y by using trigonometric ratios

sine, cosine and tangent

$tan= \frac{opposite}{adjacent}$

the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35

so...

$tan28=\frac{y}{35}$

now we solve for y using basic algebra

we want to isolate the variable (y) using inverse operations

to get rid of the 35 we multiply each side by 35

$\frac{y}{35} =y\\tan28*35=35tan28$

now we let the calculator do the rest of the work

$35tan(28)=18.60983011$

*round to the nearest thousandth*

we're left with

y = 18.610

hence your answer is B

What is 2 - 3y is less than or equal to 12? That was the question.

Ivenika [448]

Answer:

$2-3y\leq 12\\-2+2-3y\leq 12-2\\-3y\leq 10\\\frac{-3}{3}y\leq \frac{10}{3} \\y\geq \frac{10}{3}$

Y = 3x + 10<br>Y = 2x - 8<br>find the substitution <br>Show your work please ill give brainlyest

Nina [5.8K]

Answer:

x = -18, Y = -44

Step-by-step explanation:

Since Y = 2x - 8, we can substitute that into the first equation:

2x - 8 = 3x + 10

3x - 2x = -8 - 10

x = -18

Now we plug x = -18 back into the second equation:

Y = 2(-18) - 8

Y = -36 - 8

Y = -44
