Let's assume the number is N

<u>According</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u>, </u>

when I add a number to another number four times as big, the result is 30.

x+4x=30\\\\5x=30\\\\x=\dfrac{30}{5}\\\\x=\frak{6}

Answer:

x = 6

Step-by-step explanation:

Let x = first number

x+4x = 30

5x = 30

Divide by 5

5x/5 =30/5

x = 6

(Geometry course question) Explain why it is not possible to construct an equilateral triangle that has
Nutka1998 [239]

Answer:

  √3 is irrational

Step-by-step explanation:

The location of the third point of a triangle can be found using a rotation matrix to transform the coordinates of the given points.

<h3 /><h3>Location of point C</h3>

With reference to the attached figure, the slope of line AC is √3, an irrational number. This means the line AC <em>never passes through a point with integer coordinates</em>. (Any point with integer coordinates would be on a line with rational slope.)

<h3>Equilateral triangle</h3>

The line segments making up an equilateral triangle are separated by an angle of 60°. If two vertices are on grid squares, the third must be a rotation of one of them about the other through an angle of 60°. The rotation matrix is irrational, so the rotated point must have irrational coordinates.

The math of it is this. For rotation of (x, y) counterclockwise 60° about the origin, the transformation matrix is ...

  \left[\begin{array}{cc}\cos(60^\circ)&\sin(60^\circ)\\-\sin(60^\circ)&\cos(60^\circ)\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right]=\left[\begin{array}{c}x'\\y'\end{array}\right]

Cos(60°) is rational, but sin(60°) is not. For any non-zero rational values of x and y, the sum ...

  cos(60°)·x + sin(60°)·y

will be irrational.

As in the attached diagram, if one of the coordinates of the rotated point (B) is zero, then one of the coordinates of its image (C) will be rational. The other image point coordinate cannot be rational.

What is the measure of the sector shaded above?
mestny [16]

\bf \textit{area of a sector of a circle}\\\\ A=\cfrac{\pi \theta r^2}{360}~~ \begin{cases} r=&radius\\ \theta =&angle~in\\ &degrees\\ \cline{1-2} r=&6\\ \theta =&87 \end{cases}\implies A=\cfrac{\pi (87)(6)^2}{360}\implies A=\cfrac{87\pi }{10} \\\\\\ A\approx 27.332\implies \stackrel{\textit{rounded up}}{A=27.3}

An artist sold 10 paintings. Her first two sold for $50 and $350. She sold three at a gallery show for $250, $400 and $1,200. Sh
podryga [215]

Answer:

  • 150

Step-by-step explanation:

There are 10 numbers representing the selling prices of paintings.

<u>List the numbers in the ascending order:</u>

  • 50, 200, 250, 280, 350, 375, 400, 400, 410, 1200

<u>Median of the lower half is:</u>

  • 50, 200, 250, 280, 350 ⇒ Q1 = 250

<u>Median of the upper half is:</u>

  • 375, 400, 400, 410, 1200 ⇒ Q3 = 400

<u>The IQR is the difference between the upper and lower medians:</u>

  • IQR = Q3 - Q1 =
  •         400 - 250 = 150
