Answer:

a) 0.64mm

b) 7/25

Step-by-step explanation:

Felipe trabaja en una construcción ayuda a cotizar materiales entre ellos cables para diversos propósitos.El arquitecto le pidió cotizar un cable de 16/25 mm de diámetro. en los catálogos disponibles en as tiendas las medidas aparecen expresadas en números decimales como se muestra en la imagen

¿Que debe hacer felipe para saber el diámetro del cable que pidió el arquitecto?

¿que medida en forma de fracción le corresponde al cable que mide 0.28? ¿como lo determinaste? es urgenteeee GRACIAS

a) Dada la dimensión fraccionaria del cable expresada como 16/25 mm, dado que Felipe debe expresar esta fracción en decimal para obtener la medida requerida, dividiremos la expresión usando una división larga como se muestra en el anexo. Desde el archivo adjunto;

16/25 mm = 0,64 mm

b) La medida fraccionaria corresponde al cable que mide 0.28 se expresa como se muestra. Convertir 0,28 a fracción.

0.28 = 28/100 (Tenga en cuenta que dividimos por 100 porque hay dos valores decimales después del punto decimal)

Sobre la simplificación en su término más bajo

28/100 = 4 * 7/4 * 25

28/100 = 4/4 * 7/25

28/100 = 1 * 7/25

28/100 = 7/25

Por lo tanto, la medida fraccionaria que corresponde al cable que mide 0.28 es 7/25.

Solve: 3.6 (5x4) divided 3+5.0=
zavuch27 [327]

The value of the expression will be 9.

<em><u>Explanation</u></em>

Given expression is : \frac{3.6(5*4)}{3+5.0}

First we will simplify both numerator and denominator separately using <u>order of operations</u>. So....

3.6(5*4)=3.6(20)=72\\\\ and\\\\ 3+5.0=8

Thus the expression....

\frac{3.6(5*4)}{3+5.0}=\frac{72}{8}=9

Javier writes an integer on a piece of paper. The absolute value of his number is less than 4. Which is true of the possible val
mrs_skeptik [129]

Answer:

3, -2, -1, 0, 1, 2, 3

Step-by-step explanation:

Given the inequality expression |x| < 4 where x is unknown. To her the possible values of x, we must undeterstand that the absolute value of a number returns both positive and negative value.

Hence |x| can either return +x or -x

If x is positive, the inequality expression will be x<4.

If the value of x is negative, then -x<4

From -x<4

Multiply both sides by minus sign will change the sense of the inequality sign.

-(-x) > -4

x>-4

If x is greater than -4, then -4<x.

Combining both inequality will give;

-4 < x and x<4

-4<x<4

Hence the possible values of Javier's number are integers between -4 and 4.

The values are -3, -2, -1, 0, 1, 2, 3.

Which of the following functions gives the radius, r(v), of a conical artifact that is 20 inches tall as a function of its volum
irinina [24]
<h3><u>Radius as function of volume is:</u></h3>

r(v) = \sqrt{\frac{3v}{20 \pi }}\ inches

<em><u>Solution:</u></em>

<em><u>The volume of cone is given as</u></em>:

v = \frac{1}{3}\pi r^{2} h

Where,

r is the radius

h is the height

From given,

height = 20 inches

From formula,

v = \frac{1}{3}\pi r^{2} h

Rearrange , so that r is alone in left side of equation

3v = \pi r^2 h\\\\\pi r^2 h = 3v\\\\r^2 = \frac{3v}{\pi h}\\\\Take\ square\ root\ on\ both\ sides\\\\r = \sqrt{\frac{3v}{\pi h}}

Substitute h = 20

r = \sqrt{\frac{3v}{20 \pi }}

Thus, radius as function of volume is:

r(v) = \sqrt{\frac{3v}{20 \pi }}\ inches

Which of the following is a point of tangency on the circle below?<br> Help ASAP please
kumpel [21]

Answer:

Point B

Step-by-step explanation:

a point of tangency on a circle is where an outside line touches the outer circle at one point (the outside line touching it only once is what makes that line a tangent) so in this case the point of tangency is Point B
