Find the value of x. (x + 30)

Mathematics
1 answer:
taurus [48]3 years ago
8 0

Answer:

x=55

Step-by-step explanation:

The exterior angles of a polygon add to 360.

x+x+x+x+x+x+30 = 360

Combine like terms

6x+30 = 360

Subtract 30 from each side

6x+30-30 = 360-30

6x = 330

Divide by 6

6x/6 =330/6

x =55

How many 2.5 inch by 6 inch tiles will fit on a back splash that is 2.5 feet tall and 8 feet long?
Maksim231197 [3]
Area of each of the tiles = (2.5 * 6) inches^2
                                       = 15 inches^2
Now we have to get down to the case of the backsplash
1 feet = 12 inches
Then
Length of the back splash = 8 feet
                                           = (8 * 12) inches
                                           = 96 inches
Height of the back splash = 2.5 feet
                                         = (2.5 * 12) inches
                                         = 30 inches
Then
Area of the back splash = ( 30 * 96) inches^2
                                       = 2880 inches^2
So
The number of tiles required to fit in the back splash = 2880/15
                                                                                     = 192
So 192 tiles will be required to fit in the back splash. I hope the procedure is clear enough for you to understand.

Use a table of values with at least 5 values to graph the following function:
34kurt

The given expression :

y=(\frac{1}{2})^x

For coordinates:

put x = 0 then :

\begin{gathered} y=(\frac{1}{2})^0 \\ y=1 \end{gathered}

Coordinate : (x, y) = (0, 1)

Put x= 1 and simplify :

\begin{gathered} y=(\frac{1}{2})^1 \\ y=\frac{1}{2} \\ y=0.5 \end{gathered}

Coordinate : (x, y) = ( 1, 0.5)

Put x = (-2) and simplify :

\begin{gathered} y=(\frac{1}{2})^{-2} \\ y=\frac{1^{-2}}{2^{-2}} \\ y=\frac{2^2}{1^2} \\ y=2^2 \\ y=4 \end{gathered}

Coordinate : (x, y) = ( -2, 4)

Put x = (-3) and simplify :

\begin{gathered} y=(\frac{1}{2})^{-3} \\ y=\frac{1^{-3}}{2^{-3}} \\ y=\frac{2^3}{1^3} \\ y=2^3 \\ y=8 \end{gathered}

Coordinate : (x, y) = (-3, 8)

Substitute x = (-1) and simplify :

\begin{gathered} y=(\frac{1}{2})^x \\ y=(\frac{1}{2})^{-1} \\ y=\frac{1^{-1}}{2^{-1}} \\ y=\frac{2}{1} \\ y=2 \end{gathered}

Coordinate : (x, y) = ( -1, 2)

So, the coordinates are :

The graph is :

Calculate the volume of a cylindrical paint can with a diameter of 3 in and a height of 8 in.
Hoochie [10]

Answer:

Volume = 18 * pi in^3   OR IF pi=3.14 THEN   Volume = 56.52 in^3

Step-by-step explanation:

Volume = Area(circle) * Height

Volume = pi*(diameter/2)^2 *Height

Volume = pi* 2.25 * 8

Volume = 18 * pi in^3

And if pi=3.14 then:

Volume = 56.52 in^3
