Answer:

D) 115

the inside angles of a triangle always (ALWAYS) add up to 180, add 75 and 40. You get 65. Then you know that a straight line means it is 180 degrees so you subtract 65 from 180. you get 115 degrees

Part 1)

Step-by-step explanation:

If you are mentioning about the window view on the graphing calculator, then you must be note that viewing window is the part of the coordinate plane that would be visible on the screen of your graphing calculator.

If you are just viewing only a small portion of entire graph, just think of your calculator screen as a magnifying glass, enabling you to view you a piece of the entire graph.

The size of the coordinate plane is interpreted by Xmin, Xmax, Ymin, and Ymax, as seen at the left.

The zoom setting should be such that you can get the decent range for the x-values and y-values to determine the solution.

The Zoom setting 'Zstandard' is normally 10 x 10 window which is large enough to display the appropriate portion of the graph.

"ZFit" - recalculates Ymin and Ymax using current x-values to show best possible graph. The range gets adjusted so that the function will enter the window at a corner on the left side.

Part 2) Determining the solution of $x\:+\:4y\:=\:26;\:3x\:-\:4y\:=\:30$

Step-by-step explanation:

Considering the system of equations

$\begin{bmatrix}x+4y=26\\ 3x-4y=30\end{bmatrix}$

As

$x+4y=26$

$\mathrm{Subtract\:}4y\mathrm{\:from\:both\:sides}$

$x+4y-4y=26-4y$

$x=26-4y$

$\mathrm{Subsititute\:}x=26-4y$

$\begin{bmatrix}3\left(26-4y\right)-4y=30\end{bmatrix}$

$78-12y-4y=30$

$78-16y-78=30-78$

$-16y=-48$

$y=3$

$\mathrm{For\:}x=26-4y$

$\mathrm{Subsititute\:}y=3$

$x=26-4\cdot \:3$

$x=14$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$y=3,\:x=14$

The graph of the solution of the system of equation is also attached below.

Drag each tile to the correct box. Arrange the angles in increasing order of their cosines.

inna [77]

Answer:

$\frac{3\pi}{4}$

Step-by-step explanation:

we are given different angles

we can see that each angles have different denominators

so, firstly we will find common denominators

denominators are 1 , 2,3,4,6

so, LCD will be 12

now, we will make denominator of all terms 12

$\frac{3\pi}{4} =\frac{3\pi\times 3}{4\times 3}=\frac{9\pi}{12}$

$\pi =\frac{\pi\times 12}{1\times 12}=\frac{12\pi}{12}$

$\frac{7\pi}{6} =\frac{7\pi\times 2}{6\times 2}=\frac{14\pi}{12}$

$\frac{5\pi}{3} =\frac{5\pi\times 4}{3\times 4}=\frac{20\pi}{12}$

$\frac{7\pi}{4} =\frac{7\pi\times 3}{4\times 3}=\frac{21\pi}{12}$

$\frac{4\pi}{3} =\frac{4\pi\times 4}{3\times 4}=\frac{16\pi}{12}$

$\frac{3\pi}{2} =\frac{3\pi\times 6}{2\times 6}=\frac{18\pi}{12}$

$2\pi =\frac{2\pi\times 12}{1\times 12}=\frac{24\pi}{12}$

we can see that denominators are same

so, we can arrange it according to numerators as

$\frac{9\pi}{12}$

we can replace values

and we get order as

$\frac{3\pi}{4}$

Answer:

The formula for finding volume of a cone is (in this case),

V=(3.14)(r^2)(h/3)

With this formula in mind, you would simply substitute in.

V=(3.14)(2^2)(9/3)

You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.
