Determine if the question posed is a statistical question (yes) or not (no). How many apps do my classmates have on their phones?

Answer:

3 ft 3 in

Step-by-step explanation:

The radius is half the diameter.  

If the diameter is 6 ft 6 in, then the radius is 3 ft 3 in.

Answer:

[tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]

Step-by-step explanation:

The question is incomplete as the attachment to solve segment DE is missing. However, see attached for complete question.

Given

[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]

Required

Find x

Length of DE

To find x, we need to first simplify the given equation

[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]

Multiply both sides by [tex]9(2x+3)[/tex]

[tex]\frac{5}{9} * 9(2x + 3) = \frac{9}{(2x+3)} * 9(2x + 3)[/tex]

[tex]5(2x + 3) = 9(9)[/tex]

[tex]10x + 15 = 81[/tex]

Subtract 15 from both sides

[tex]10x + 15 - 15 = 81 - 15[/tex]

[tex]10x = 66[/tex]

Divide both sides by 10

[tex]\frac{10x}{10} = \frac{66}{10}[/tex]

[tex]x = \frac{66}{10}[/tex]

[tex]x = 6.6[/tex]

From the attached;

[tex]DE = 2x + 3[/tex]

Substitute 6.6 for x

[tex]DE = 2(6.6) + 3[/tex]

[tex]DE = 13.2 + 3[/tex]

[tex]DE = 16.2[/tex]

Hence [tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]

Answer: 6.6 for the first x

Length of DE is 16.2

Also these are correct!

Answer:

y-7x>4

Step-by-step explanation:

Substitute the point (0, 0) for all of the equation and see which one will be true. The only reason why the 3rd equation is true is because (0) - 7(0) equals to 0 and 0 is greater than -4.

Answer:

C

Edge 2021

Answer:

The y-intercept is 2.

Step-by-step explanation:

We can find the y-intercept by looking at the linear equation y = mx + b.

m = slope

b = y-intercept

====================================================

Let's find the y-intercept of this line.

You should notice that the equation is written in Slope-Intercept Form:

[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]

Where

m -> slope

b -> y-intercept

In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.

=========================================================

Answer: B

Step-by-step explanation:

Answer:

Step-by-step explanation:

For a point to be a solution to a system of inequalities, the points must make the signs of the inequalities true.

For example, the points must give results like 2<3 or 0>-2, these are true solutions. If the points gives 1>2, then that point is not a solution.

Answer & Step-by-step explanation:

[tex]Circumference=d\pi[/tex]

The diameter of the circle is 24 mm. So, let's add in the diameter and find the circumference of the circle.

[tex]Circumference=(24)\pi[/tex]

We will use 3.14 for pi.

[tex]Circumference=75.36[/tex]

So, the circumference of the circle is 75.36 mm.

Answer:

[tex]1)13x - 15 = 12x + 16 \\ 13x - 12x = 15 + 16 \\ x = 31[/tex]

[tex]2)9x - 19 = 2x - 5 \\ 9x - 2x = 19 - 5 \\ 7x = 14 \\ \frac{7x}{7} = \frac{14}{7} \\ x = 2[/tex]

[tex]3)16x - 35 = 7x - 8 \\ 16x - 7x = 35 - 8 \\ 9x = 27 \\ \frac{9x}{9} = \frac{27}{9} \\ x = 3[/tex]

[tex]4)6x - 5 = 13 - 3x \\ 6x + 3x = 5 + 13 \\ 9x = 18 \\ \frac{9x}{9} = \frac{18}{9} \\ x = 2[/tex]

[tex]5)4x - 9 = 6 - x \\ 4x + x = 9 + 6 \\ 5x = 15 \\ \frac{5x}{5} = \frac{15}{5} \\ x = 3[/tex]

[tex]6)5x - 2 = 10 - x \\ 5x + x = 2 + 10 \\ 6x = 12 \\ \frac{6x}{6} = \frac{12}{6} \\ x = 2[/tex]

Answer:

La distancia en línea recta que separa los segmentos paralelos es 60cm.

Step-by-step explanation:

Esta pregunta se puede resolver usando el teorema de Pitágoras:

[tex] \\ c^2 = a^2 + b^2[/tex] [1]

Es decir, en triángulos rectágulos, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos de dicho triángulo. Un triángulo es rectángulo cuando el ángulo que forman sus dos catetos es recto o de 90 grados sexagesimales.

Es importante notar que la letra N tiene dos lados paralelos y el lado oblicuo (o inclinado) une ambos lados paralelos. Pues bien, la letra N puede formar dos triángulos iguales. Escojamos uno de ellos para obtener la respuesta, es decir, la distancia en línea recta que separa los segmentos paralelos (segmentos verticales de la N)

El lado oblicuo (inclinado) es la hipotenusa de ese triángulo (es decir, c). De los catetos, uno está representado por uno de los segmentos paralelos (verticales) de la N (digamos que es b), y, el otro cateto, es la distancia horizontal que une ambos segmentos verticales (digamos que es a).

Si unimos el segmento inferior del cateto b con el extremo inferior de la hipotenusa, se forma el cateto a. Este cateto a forma un ángulo recto con el cateto b y, por lo tanto, forma un triángulo recto. Los lados de un triángulo recto pueden resolverse usando el teorema de Pitágoras, descrito en [1].

Usando [1] y despejando a, tenemos:

[tex] \\ c^2 = a^2 + b^2[/tex]

Restamos [tex] \\ b^2[/tex] de ambos lados de la igualdad:

[tex] \\ c^2 - b^2 = a^2 + b^2 - b^2[/tex]

[tex] \\ c^2 - b^2 = a^2 + 0[/tex]

[tex] \\ c^2 - b^2 = a^2[/tex]

Luego

[tex] \\ a^2 = c^2 - b^2[/tex]

Extrayendo la raíz cuadrada en cada lado de la igualdad:

[tex] \\ \sqrt{a^2} = \sqrt{c^2 - b^2}[/tex]

Entonces

[tex] \\ a = \sqrt{c^2 - b^2}[/tex]

Asimismo, tenemos que [tex] \\ c = 65[/tex]cm y [tex] \\ b = 25[/tex]cm

Entonces,

[tex] \\ a = \sqrt{65^2 - 25^2}[/tex]

[tex] \\ a = \sqrt{4225 - 625}[/tex]

[tex] \\ a = \sqrt{3600}[/tex]

[tex] \\ a = 60[/tex]cm

De esta manera, el valor de a, o la distancia en línea recta que separa los segmentos paralelos, es 60cm.

Podemos comprobar el resultado anterior haciendo uso del mismo teorema de Pitágoras:

[tex] \\ 65^2 = 60^2 + 25^2[/tex]

[tex] \\ 4225 = 3600 + 625[/tex]

[tex] \\ 4225 = 4225[/tex]

Answer:

sphere

Step-by-step explanation:

Human heads are close to circles and sometimes are circles

Sphere is the best model for the head of a human being.

A human head definitely doesn't represent a Cone neither a Pyramid.

Now a cylinder is a solid which is circular at its edges and straight in its length which clearly does not model the human head. Now the Sphere, it does closely represent the outside figure of a human head.  

Thus Sphere is the best model for a human head.

Therefore option D, sphere is the correct answer.

Answer:

x = 132

Step-by-step explanation:

The angles are supplementary so the add to 180 degrees

x+48 = 180

x+48-48 = 180-48

x =132

Answer:

Step-by-step explanation:

Tips = 20% of 47.60

Step-by-step explanation:

Solve the equation:
