V = LWH

Change the dimensions to decimal numbers.

L = 3.75 m
W = 1.5 m
H = 2 m

V = (3.75 m)(1.5 m)(2 m)

V = 11.25 m^3

Find 5 points by plugging in Xs for y=2x-3

0 ---> -3

1 ----> -1

2 ---> 1

3 ---> 3

4 ---> 5

then graph the points. X is the first number, and how far you go along the horizontal axis. Y is the second number, and determines how far you go along the vertical axis.

3. What are the coordinates of the center and the length of the radius of the circle whose equation is(x + 1)^2 + (y - 5)^2 = 16
hram777 [196]

Given data:

The given equationn of the circle is (x + 1)^2 + (y - 5)^2 = 16.

The standard equation of the circle is,

(x-a)^2+(y-b)^2=r^2

The given equation can eb written as,

(x-(-1))^2+(y-5)^2=4^2

Compare the above equation with standard equation.

\begin{gathered} a=-1 \\ b=5 \\ c=4 \end{gathered}

Thus, the coordinate of centre is (-1, 5) and radius is 4.

¿Cuál es el sistema de ecuaciones que permite obtener el precio por litro de los dos tipos de
vampirchik [111]

El sistema de ecuaciones que permite obtener el precio por litro de los dos tipos de gasolina es 8x + 10y = 302.12 y 12x + 12y = 400.08​ (opción D)

Una ecuación es una expresión matemática que se caracteriza por representar una igualdad entre dos miembros separados por el signo igual. La ecuaciones incluyen elementos conocidos e incógnitas relacionados mediante operaciones matemáticas.

De acuerdo a lo anterior la respuesta correcta es 8x + 10y = 302.12 y 12x + 12y = 400.08​. Por que estas ecuaciones expresan matemáticamente los datos que se tienen y las incógnitas con las letras <em>x</em> y <em>y</em>.

Por ejemplo, la primera expresa que 8 (litros) por el precio del galón de gasolina Magnum (<em>x</em>), más 10 (litros) por el precio del galón de gasolina Premium (<em>y</em>) es igual a 302.12, que fue el precio total que pagó Carlos por la gasolina.

La segunda ecuación expresa que 12 (litros) por el precio del galón de gasolina Magnum (<em>x</em>) más 12 (litros) por el precio del galón de gasolina Premium (<em>y</em>) es igual a 400.08, que fue el precio total que Raquel pagó por la gasolina.

Esta pregunta está incompleta porque faltan las opciones e información sobre la gasolina. A continuación está la información completa y las opciones.

Carlos compró 8L de gasolina Magnum y 10 litros de gasolina premium por 302.12

Raquel compró 12L de gasolina Premium y 12L de gasolina magnum por 400.08

A) 8x + 12y = 302.12

10x + 12y = 400.08

B) 8x + 12y = 400.08

10x + 12y = 302.12

C) 8x + 10y = 400.08

12x + 12y = 302.12

D) 8x + 10y = 302.12

12x + 12y = 400.08​

I don’t understand this!
Korvikt [17]

Answer:

635

Step-by-step explanation:

so basically you need to make an equation to find out what number, when put through all of those operations, will still equal the same number in the end. the way you do that is with an equation. so let's say our starting number is <em>x</em>, since we don't know its value yet.

the final equation is (((((((x/5)+6)/7)-8)9)+114)3)-4 = x

basically it's just x, all those different operations in that order, which is why you need parentheses, equals to x again because it's the same in the end. when you solve that you get 635
