The volume of a cone is 3x* cubic units and its height is x units.

igor_vitrenko [27]

Answer:

The radius of a cone is $\dfrac{3}{\sqrt{\pi} }\ \text{units}$ .

Step-by-step explanation:

The formula of the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

r is radius of cone

h is height of cone

We have,

Volume of a cone is 3x cubic units and height is x units. Putting the values of volume and height such that,

$r=\sqrt{\dfrac{3V}{\pi h}}\\\\r=\sqrt{\dfrac{3\times 3x}{\pi x}} \\\\r=\sqrt{\dfrac{3\times 3}{\pi}}\\\\r=\sqrt{\dfrac{9}{\pi}}\\\\r=\dfrac{3}{\sqrt{\pi} }\ \text{units}$

So, the radius of a cone is $\dfrac{3}{\sqrt{\pi} }\ \text{units}$ .

La edad de Alejandro equivale a las dos quintas partes de la edad de Andrea. Si la suma de

Mariana [72]

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

En esta pregunta debemos traducir el enunciado en ecuaciones algebraicas y resolver el sistema resultante. Tras una lectura cuidadosa tenemos el siguiente sistema de ecuaciones:

$y = \frac{2}{5}\cdot x$ (1)

$x + y = 56$ (2)

Donde:

$x$ - Edad de Andrea, en años.
$y$ - Edad de Alejandro, en años.

A continuación, procedemos a resolver el sistema:

(1) en (2):

$x + \frac{2}{5}\cdot x = 56$

$\frac{7}{5}\cdot x = 56$

$7\cdot x = 280$

$x = 40$

Por (1):

$y = \frac{2}{5}\cdot 40$

$y = 16$

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

Cougar Park is shaped like a parallelogram and has an area of 1/10 square mile. It’s base is 3/8 mile. What is its height?

VikaD [51]

To find the missing dimension (the height) you can use the formula A=bh and substitute and let you know. 1/10=3/8h. To find the missing factor (h) you will divide both sides by 3/8. 1/10 divided by 3/8 is the same as 1/10 x 8/3. The answer is 4/15 mile. You show this has h=4/15 mi.
