Which expression represents, six times a number plus 8 times a number?

Para el diseño de un tanque de tratamiento de agua se determina que su centro está ubicado en la posición (0;14) metros y está r

Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

$x^{2} +y^{2} -28y + 180= 0$

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

$x^{2} +y^{2} -28y + 196 = -180 +196$

Entonces obtenemos

$x^{2} + (y-16)^{2} = 16$

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

water the tank will hold = 14.583 gallons

<h3>What is cuboid ?</h3>

A cuboid is a three-dimensional or solid shape.
A cuboid is a convex polyhedron that has six rectangular faces, eight vertices, and twelve edges.
Another name for a cuboid is a rectangular prism. A cube is a cuboid with six square faces.
The basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

Given : A fish tank has a volume = 3360 cubic Inches.

The length of the tank is =14 inches

the width is = 12 inches.

The height of the tank is = 20 inches.

If one fluid ounce is = 1.8 cubic inches

Volume of tank = 14 * 12 * 20 = 3360 cubic inches

1.8 cubic inches = one fluid ounce

3360 cubic inches = 3360/1.8 fluid ounce

= 5600/3 fluid ounce

As we know,

1 gallons = 128 fluid ounces

water the tank will hold =( 5600/3 ) / 128
