Please simplify 10{N + 3).

lana [24]

Answer:

Step-by-step explanation:

I must assume that you meant 10(N + 3). Let's not mix { with ).

10(N + 3) is as simple as this expression gets. You could, however, re-write it as 10N + 30.

Kia wants to order a large pizza from Frank's Pizza. Each large cheese pizza costs $8.75 and each additional topping costs $0.5

Afina-wow [57]

<h2>Hello!</h2>

The answer is: A. 8.75 + 0.50 x ≤ 15.00

By isolating the variable (x), we have:

$8.75 + 0.50x \leq15.00 \\0.50x\leq 15-8.75\\0.50x\leq 6.25\\x\leq \frac{6.25}{0.50}\\x\leq 12.5$

So, with the result of x ≤ 12.5 , we can know that the most amount of additional toppings Kia got, is 12 toppings.

The inequality is telling us that Kia will spend 15$ or less if she orders 12 toppings or less.

Have a nice day!

A hemisphere has an area of 256 pi cm^2. What is its volume?

Amanda [17]

$\bf \begin{array}{llll}
\textit{surface area of a sphere}\\\\
A=4\pi r^2
\\\\\\
\textit{a hemisphere is half that}\\\\
A=\cfrac{4\pi r^2}{2}\implies A=2\pi r^2
\end{array}\qquad r=radius
\\\\\\
\textit{now, we know the area is }256\pi \implies 256\pi =2\pi r^2
\\\\\\
\cfrac{256\pi }{2\pi }=r^2\implies \sqrt{128}=r\implies \boxed{8\sqrt{2}=r}
\\\\
-----------------------------\\\\$

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

pantera1 [17]

Answer:

78.6m of fencing

That would cost $982.50

Step-by-step explanation:

Perimeter: 2(22.7)+2(16.6)=P

P = 78.6

Cost: 78.6*12.50

C = 982.50
