Answer

54 \sqrt{3}

Step-by-step explanation:

Each interior angle is 120°for an hexagon.... Bisecting each will give an angle of 60° and thus dividing the hexagon into 6 equilateral triangles as the Bisecting lines meet at the centre of the hexagon. So find area of each equilateral triangle and multiply by 6

Area=

\frac{1}{2} b \times h \times 6 \\  = 3bh \\  = 3 \times 6 \times 3 \sqrt{3}

= 54 \sqrt{3 } cm ^{2}

The equation looks like this:

26=x*3.5+8.50

where x is the number of pen you bought.

We solve it like this:
first, we subtract 8.50 from both sides:

17.50 =3.5*x

now we divide both sides by 3.5:
5=x

so you purchased 5 pens.

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?
Andreas93 [3]

Given:

Consider the below figure attached with this question.

m\angle 3=(x+30)^\circ and m\angle 4=(2x-80)^\circ.

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

m\angle 3=m\angle 4

(x+30)^\circ=(2x-80)^\circ

x+30=2x-80

x-2x=-30-80

-x=-110

x=110

Now,

m\angle 3=(110+30)^\circ

m\angle 3=140^\circ

Therefore, the measure of angle 3 is 140 degrees.

Linear equation <br><br> 4.5 + 1.5y=24<br> x-y=4
WARRIOR [948]
4.5x + 1.5y = 24 ⇒ 4.5x + 1.5y = 24
1.0x -  1.0y = 4   ⇒<u> 4.5x - 4.5y = 18</u>
                                             <u>6y</u> = <u>6</u>
                                              6     6
                                               y = 1
                             4.5x + 1.5(1) = 24
                                 4.5x + 1.5 = 24
                                 <u>         - 1.5    - 1.5</u>
                                          <u>4.5x</u> = <u>22.5</u>
                                           4.5      4.5
                                               x = 5
                                          (x, y) = (5, 1)

Solve the inequality
worty [1.4K]

Treat it just like and equation at first. Multiply the 10 on both sides to get rid of it, leaving you with 50 \leqx.  Then on the number line, since there is a line under it, you would make a filled in circle and an arrow pointing towards 51 and beyond
