An experienced ice skater spins on the ice, creating a perfect circle with a radius of 1 yard. What is the circle's circumferenc

zmey [24]

The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula C=2πr or C=πd, where r refers to the radius.

In this exercise is given a circle, which radius is 1 yard and it is asked to find its circumference and use 3.14 as the value of pi. In order to do that, you should substitute the given value of the radius and pi into the formula C=2πr.

$C=2 \pi r$
$C=2(3.14)(1 yd)$
$C=6.28 yards$

The circumference of the circle is 6.28 yards.

Resolver el siguiente sistema de ecuación:

snow_tiger [21]

Answer:

$x=-1\\y=4$

Step-by-step explanation:

$\frac{5x+2y}{3}=1$

$\frac{2x+y}{2}=1$

Vamos a utilizar el método de sustitución. Vamos a despejar la segunda ecuación por alguna de las variables. Elegiré la y porque esta sola.

$\frac{2x+y}{2}=1$

Vamos a empezar por eliminar ese 2 del denominador. Para hacer esto, multiplicamos por 2 ambos lados de la ecuación.

$2x+y=1*2$

$2x+y=2$

Como vamos a despejar la y, restamos 2x en ambos lados.

$y=2-2x$

Listo.

------------------------------------------------------------------------

Procedemos a reemplazar el valor de y en la primera ecuación.

$\frac{5x+2y}{3}=1$

$\frac{5x+2(2-2x)}{3}=1$

$\frac{5x+4-4x}{3} =1$

Procedemos a operar términos semejantes.

$\frac{x+4}{3} =1$

Nos deshacemos del 3 multiplicando.

$x+4=1*3\\x+4=3$

Restamos 4

$x=3-4\\x=-1$

-----------------------------------------------------------------------------

Una vez encontrado el valor de x, procedemos a reemplazar en cualquier ecuación para encontrar el valor de y. Usaré la segunda ecuación.

$\frac{2x+y}{2}=1$

$\frac{2(-1)+y}{2}=1$

Procedemos a resolver;

$\frac{-2+y}{2} =1$

Multiplicamos por 2.

$-2+y=1*2$

$-2+y=2$

Sumamos 2

$y=2+2\\y=4$

-------------------------------------------------------------------------------

Para comprobar que los valores son correctos, reemplazamos ambos valores en cualquier ecuación y el resultado debe ser igual.

Usaré la primera.

$\frac{5x+2y}{3} =1$

$\frac{5(-1)+2(4)}{3} =1$

Resolvemos;

$\frac{-5+8}{3} =1$

$\frac{3}{3}=1$

$1=1$

The answer is 116.
You would do 174 / 3 since Tyler collect twice as many as max did, to get how much max has, and doubled it by doing 58 x 2

Find three consecutive even integers. Such that 7 times of first integer is 4 more than the sum of second and third integers

attashe74 [19]

Answer:

1st even integer = 2

2nd even integer = 4

3rd even integer = 6

Step-by-step explanation:

Let the consecutive even integers be:

1st = 2(x)

2nd= 2(x +1) = 2x + 2

3rd = 2(x + 2) = 2x + 4

According to Given conditions:

7(2x) = 4 + 2x +2 + 2x + 4

By Simplifying:

14x = 10 + 4x

Subtracting 4x from both sides

14x - 4x = 10 + 4x -4x

10x = 10

Dividing both sides by 10 we get:

x = 1

Now putting value of x in supposed integers:

1st even integer = 2(1) = 2

2nd even integer = 2(1)+2 = 4

3rd even integer = 2(1) + 4 = 6

I hope it will help you!
