PLEASE HELP!!!!!
Elodia [21]

Answer:

  A, D, E (probably preferred)

  B, C, F (also true)

Step-by-step explanation:

"This situation" problems are almost always ambiguous. The first problem is to figure out what it is about "this situation" that you want to model.

__

If we want to model concession stand revenue in a general way, then statements B, C, and F could represent "this situation." No specific values can be determined from this model.

__

More likely, we want to model the details of sales and revenue, so we want to know the exact numbers of water bottles and hamburgers that were sold. For "this situation," we can assign variables to the numbers of items of each type, and write equations for the total number of items and for the revenue their sales generates. Appropriate statements about this interpretation of the problem are those of A, D, and E:

  A: x could represent bottles sold

  D: y could represent hamburgers sold

  E: The system of equations could be 2.50x +5.50y = 1325; x +y = 350.

_____

The solution to the last model is 200 bottles were sold for revenue of $500, and 150 hamburgers were sold for revenue of $825.

A hemisphere has an area of 256 pi cm^2. What is its volume?
Amanda [17]
\bf \begin{array}{llll}
\textit{surface area of a sphere}\\\\
A=4\pi r^2
\\\\\\
\textit{a hemisphere is half that}\\\\
A=\cfrac{4\pi r^2}{2}\implies A=2\pi r^2
\end{array}\qquad r=radius
\\\\\\
\textit{now, we know the area is }256\pi \implies 256\pi =2\pi r^2
\\\\\\
\cfrac{256\pi }{2\pi }=r^2\implies \sqrt{128}=r\implies \boxed{8\sqrt{2}=r}
\\\\
-----------------------------\\\\

\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad r=radius
\\\\\\
\textit{a hemisphere is half that}\\\\
V=\cfrac{\frac{4}{3}\pi r^3}{2}\implies V=\cfrac{\frac{4\pi r^3}{3}}{\frac{2}{1}}\implies V=\cfrac{4\pi r^3}{3}\cdot \cfrac{1}{2}
\\\\\\
V=\cfrac{2\pi r^3}{3}
\\\\\\
\textit{now, we know the radius is }8\sqrt{2}\implies V=\cfrac{2\pi (8\sqrt{2})^3}{3}
\\\\\\
V=\cfrac{2\pi (8^3\sqrt{2^3})}{3}\implies V=\cfrac{2\pi \cdot 512\cdot 2\sqrt{2}}{3}
\\\\\\
\boxed{V=\cfrac{2048\pi \sqrt{2}}{3}}

What is the solution to the equation 8+4=2(x-1)?<br> O 5<br> O11/2<br> O 13/2<br> O 7
maks197457 [2]

Answer:

5

Step-by-step explanation:

Simplifying

8 + 4 = 2(x + 1)

Combine like terms: 8 + 4 = 12

12 = 2(x + 1)

Reorder the terms:

12 = 2(1 + x)

12 = (1 * 2 + x * 2)

12 = (2 + 2x)

Solving

12 = 2 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, and all other terms to the right.

Add '-2x' to each side of the equation.

12 + -2x = 2 + 2x + -2x

Combine like terms: 2x + -2x = 0

12 + -2x = 2 + 0

12 + -2x = 2

Add '-12' to each side of the equation.

12 + -12 + -2x = 2 + -12

Combine like terms: 12 + -12 = 0

0 + -2x = 2 + -12

-2x = 2 + -12

Combine like terms: 2 + -12 = -10

-2x = -10

Divide each side by '-2'.

x = 5

Simplifying

x = 5
