Answer 2

Answer:

3x + 8 = 15

(If you wanted to solve it then:) x = 7/3

Step-by-step explanation:

Let's convert that into an equation.

Let "x" be the number.

3x + 8 = 15

If the question was to answer it, look below:

3x + 8 = 15

3x = 7

The temperature at 8 p.m. was 6 degrees. at 2 p.m. the temperature decreased 13 degrees. What was the temperature at 2 a.m.?

Answers

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

I know the answer is 64, but how? Can someone please explain me to me how to work this out?

Answers

Well the square root of 64 is 8, and the cube root of 64 is 4. They’re perfect whole numbers. We know 4 x 4 = 16 is a square from the fact above, and also because of what a square means. But we can go one step further. 4 x 16 = 64 is the product of two squares, so it is also a square. But you can also write it as 64 = 4 x 4 x 4, making it a cube.

What is Polygon?

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.

There is 33 students in the class

The heights of six students Aaron, Betty, Carrie, Dan, Evelyn and Frank are 58 inches, 60 inches, 63 inches, 64 inches, 68 inches and 69 inches. Carrie is 4 inches shorter than Aaron. The girls (Betty, Carrie and Evelyn) are the three shortest students. Dan is one inch shorter than Frank. Betty is the shortest student. What is the sum of Frank’s height and Evelyn’s height, in inches?

Answers

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.

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

un icosagono es un poligono que contiene 20 lados, cuantas diagonales se pueden trazar desde todos sud vertices si cada lado mide 15cm y su area es 900cm2?

Answers

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:

[tex]d[/tex] - Cantidad de diagonales.[tex]n[/tex] - Cantidad de lados.

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.
