Answer:

El número de diagonales de un icoságono = 170 diagonales

Step-by-step explanation:

Los parámetros dados son;

El número de lados del polígono = 20

La longitud de cada lado = 15 cm.

El área del polígono = 900 cm²

La fórmula para encontrar el número de diagonales, ∑D, de un polígono de n lados se presenta como sigue;

Número de diagonales, ∑D = n (n - 3) / 2

Por lo tanto, el número de diagonales de un icoságono (20 lados) ∑D (20) es;

∑D (20) = 20 × (20 - 3) / 2 = 170 diagonales.

Se pueden trazar 170 diagonales en un icoságono.

Matemáticamente, es posible determinar la cantidad de diagonales en función del cantidad de lados del polígono a través de la siguiente fórmula:

[tex]d = \frac{n\cdot (n-3)}{2}[/tex] (1)

Donde:

Si sabemos que [tex]n = 20[/tex], entonces la cantidad de diagonales del icoságono es:

[tex]d = \frac{20\cdot (20-3)}{2}[/tex]

[tex]d = 170[/tex]

Se pueden trazar 170 diagonales en un icoságono.

Answer:

y = 1500 + 800x

Step-by-step explanation:

This is the answer because Elisa charges 1500 dollars no matter what. That value is not dependant on anything. Every hour she is with the client is 800 dollars. That is why it is represented as 800x. X being the amount of hours. You add the two together to find how much Elisa's services cost.

Answer: 132

Step-by-step explanation: I think it is 132 because C + 4 = A, D + 1 = F, and B is shortest. so the order is FDAECB with Frank at 69 and Evelyn at 63. Carrie has to be at 60 because Aaron, who is 64, is 4 inches taller than Carrie. So, when you add 69 and 63 together, you get 132. Also just to check, Dan, who is 68, is one inch shorter than Frank, who is the tallest. This is only true because the girls are the youngest.

The order of rotational symmetry for a rhombus is 2.

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end

A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral.

In a rhombus, opposite sides are parallel and the opposite angles are equal.

All the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles

Rotational Symmetry of a Rhombus has four equal sides but of varying angles.

A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees

Hence,  the order of rotational symmetry for a rhombus is 2.

Answer:

y = - 2(x + 4)² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (- 4, 6 ) , thus

y = a(x - (- 4) )² + 6 , that is

y = a(x + 4)² + 6

To find a substitute (- 2, - 2) into the equation

- 2 = a(- 2 + 4)² + 6 ( subtract 6 from both sides )

- 8 = a(2)² = 4a ( divide both sides by 4 )

- 2 = a , thus

y = - 2(x + 4)² + 6 ← equation in vertex form

Answer:

3 hours for landscaping and 9 hr for babysitting

Step-by-step explanation:

So take x to be babysitting and y to be landscaping

The equation will be 7x+11y=96

$7 for the baby sitting and $11 for the landscaping and 96 for the total

So then it says 3 times as many hours than landscaping so x equation will look like this x=3*y

So replace the terms - 7*(3y)+11y=96

Simplify (7*3)y+11y=96

Simplify more 21y+11y=96

You get 32y=96

Divide both sides by 32 to have y only 32y/32=96/32

You will get y=3

So landscaping will be 3 hours and it says that babysitting is 3 times so multiply 3 you get 9

So landscaping is 3 hours and babysitting is 9 hours

Hope this help

Answer:

x=25

Step-by-step explanation:

All angles in a triangle add up to 180°, so add all the angles together

(2x+15)+(x+10)+(3x+5)=6x+30

So that means... 6x+30=180°

Get rid of the 30, so... 180-30=150

6x=150°

Divide each by 6

6x/6=x

150/6=25

x=25

Step-by-step explanation:

Given parameters:

    Temperature at 8pm = 6°C

    Temperature at 2am = decreased by 13°C

Unknown:

Temperature at 2am

Solution:

Since this is a temperature decrease problem, the temperature at 2am should be lesser.

 Temperature at 2am = Temperature at 8pm - Temperature decrease

                                    = 6°C - 13°C

                                     = -7°C

Answer:

x < 3

Step-by-step explanation:

4x - 7 < 5

Add 7 to both sides.

4x < -2

Divide by 4 to both sides to get x alone.

x < 3

To check the answer if it's right or not, you can just plug in the 3 for x and multiply it by 4 which would equal 12 and subtract 12 - 7 which would equal 5.
