Si el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, entonces será igual a: * 1 punto 6 4 -2 -6

Answers

Answer:

4

Step-by-step explanation:

Para empezar el maximo común divisor (MCD) de dos números se refiere al número en común que tienen ambos números, entre los cuales pueden ser divididos. En el caso del máximo se refiere al número más alto posible en que ambos números pueden ser divididos.

Para poder saber esto, es necesario anotar los factores en los cuales pueden ser divididos ambos números. Sin embargo, ya que son cantidades altas, puede tomar mucho tiempo determinar esto, por lo tanto nos vamos a la respuesta final.

Sabemos que el MCD de 132 y 6432 es disminuido en 8 unidades, es decir, se le resta 8 al MCD de esos números, y ese número debe coincidir con alguna de las opciones puesta ahí. Por lo tanto, lo que vamos a hacer para resolverlo rápidamente es sumarle 8 a cada una de las opciones y luego, verificaremos si el número obtenido es divisor de 132 y 6432.

Obtención del MCD original:

a) 6 + 8 = 14

b) 4 + 8 = 12

c) 2 + 8 = 6

d) 6 + 8 = 2

Con estos resultados, veamos cual de ellos es el MCD de 132 y 6432.

Para el 6432:

6432 / 2 = 3216

6432 / 6 = 1072

6432 / 12 = 536

6432 / 14 = 459,24

Podemos observar con estos resultados que el 14 queda descartado al tener un resultado decimal, por lo tanto debe ser 2, 6 o 12. Veamos la cuenta con el 132:

Para el 132:

132 / 2 = 66

132 / 6 = 22

132 / 12 = 11

Podemos observar ahora en este caso que el 132 es divisible entre 12, por lo tanto, es el MCD entre 132 y 6432, asi que se concluye que el resultado de disminuir por 8 el MCD de ambos números es:

12 - 8 = 4

Exitos

Por definición de máximo común divisor,

MCD

Se denomina máximo común divisor o MCD al mayor número que divide exactamente a dos o más números a la vez. Es decir, MCD de dos o más números es el mayor número que divide a todos de manera exacta.

En otras palabras, el máximo común divisor o MCD es la cifra más alta por la cual se puede dividir un conjunto de números, dando como resultado un número entero.

Recordar que un divisor puede definirse formalmente como aquel número que está contenido en otro de forma exacta una cantidad n de veces.

Cálculo de MCD

Para calcular el máximo común divisor de dos o más números, en primer lugar se debe descomponer esos números en factores primos.

La descomposición de un número en factores primos es encontrar los números primos que se multiplican para formar ese número, recordando que los números primos son aquellos que solo se dividen por sí mismos y por 1.

El máximo común divisor se obtiene escogiendo solo los factores primos comunes a los números, elevados al menor exponente. Es decir, se debe elegir solo los factores comunes, y los que se repitan son elegidos elevados a la mínima potencia.

Este caso

La descomposición en factores primos es:

6432= 2⁵×3×67

132= 2²×3×11

Entonces, el MCD es calculado como:

MCD (6432, 132)= 2²×3

MCD (6432, 132)= 12

Por último, el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, por lo que:

12 - 8= 4

En resumen, si el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, entonces será igual a 4.

The ratio of the length of a room to its width is 5 to 3. What is the width of a room if its length is 30 feet? Media558a6e2383191.Gif

Answers

Answer:

18ft

Step-by-step explanation:

Given data

Ratio of length to width = 5:3

Length = 30ft

Apply the part to part method

let the width be x

5/3= 30/x

cross multiply

5x= 30*3

5x= 90

x= 90/5

x=18 ft

Hence the width is 18ft

If a triangle has two sides that are 17 meters & 4 meters.

What statement below best describes the range of values

the 3rd side could be?

Smaller than 20 meters

O Larger than 13 meters

Between 13 meters & 21 meters

Larger than 21 meters

Answers

Answer:

Between 13 meters & 21 meters

Step-by-step explanation:

Sum of two sides of a triangle must be greater than the third side and difference of two sides must be less than the third side.

Sum of two sides [tex]=17+4=21[/tex] meters

Difference of two sides [tex]=17-4=13[/tex] metres

Therefore,

[tex]13<[/tex] third side [tex]<21[/tex]

[tex]1/25*k^2=\frac{k^2}{25}[/tex]

Answer:  [tex]\frac{1}{25}k^2[/tex]

This is equivalent to [tex]\frac{k^2}{25}[/tex]

In decimal form, this is equivalent to 0.04k^2

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

Work Shown:

We have the two pieces 1/5 and k, all in the parenthesis being squared.

Square each piece

Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25squaring the k value leads to k^2

So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]

In decimal form, this is 0.04k^2 because 1/25 = 0.04

A drawing of a surfboard in a catalog, it shows its length as 8 4/9 inches. Find the actual length of the surfboard if 1/3 inch length from the drawing corresponds to 3/8 foot of the actual surfboard.

Answers

Answer:

9.5 feets

Step-by-step explanation:

Length of drawing = 8 4/9 inches

Scale : 1/3 inch in drawing = 3/8 actual length

Length of drawing / drawing scale

8 4/9 = 76/9 inches

Number of 1/3 inches in total length of drawing :

76/9 ÷ 1/3

76/9 * 3 / 1

(76*3) /(9*1) = 228 /9 = 9 3/9 = 9 1/3

9 1/3 * 3/8 foot

(228 / 9) * (3 /8)

(228/3) * (1/ 8)

228 / 24

= 9.5 feet

Alice's average mark for 4 Science exams is 68%. Can Alice score enough marks in a fifth exam so that her average mark increases to 75?%? Give reasons.

Answers

Answer:

It is not possible for Alice to score an average of 75% because what she needs to score in the fifth exam exceeds the maximum possible score.

Step-by-step explanation:

She scored an average 68% in all 4 exams.

This means; (68% + 68% + 68% + 68%)/4

Now, a fifth exam is added and we want to know if her average can now be 75%.

Thus, let the score in the 5th exam be x and we now have;

(68% + 68% + 68% + 68% + x)/5 = 75%

Multiply both sides by 5 to get;

(68% + 68% + 68% + 68% + x) = 375%

272% + x = 375%

x = 375% - 272%

x = 103%

The maximum score is 100% and therefore it is impossible for her to score 103%. Therefore it is not possible for Alice to score an average of 75%

Step-by-step explanation:

Given

[tex]Size = \frac{1}{4}\ cup[/tex]

[tex]Scoop = 2[/tex]

Required

Determine the size of cup for 1 scoop

For two scoops, we have:

[tex]Recipe = \frac{1}{4}+ \frac{1}{4}[/tex]

Take LCM

[tex]Recipe = \frac{1+1}{4}[/tex]

[tex]Recipe = \frac{2}{4}[/tex]

[tex]Recipe = \frac{1}{2}[/tex]

This implies that, the amount of recipe is 1/2

If he uses a cup of size 1/2, he would only need 1 scoop.

Hence:
