Answer: B. 84 in²

Step-by-step explanation:

Divide the area into two regions: a rectangle and a trapezoid (depicted in the attached photo).

Find the area of the rectangle:

Area of a rectangle=length*width

Area of rectangle=(5 in)( 10 in)

Area of rectangle=50 in²

Next, calculate the area of the trapezoid:

Area of trapezoid= $\frac{h(b_{1} +b_{2}) }{2}$

h=10 in-6 in

h=4 in

$b_{1} =15 in$

$b_{2} =15 in-5 in$

$b_{2} =10 in$

Area of trapezoid= $\frac{4in(7 in+10in)}{2}$

Area of trapezoid= $\frac{4(17in^{2}) }{2}$

Area of trapezoid= $\frac{68in^{2} }{2}$

Area of trapezoid= $34in^{2}$

Add the area of the trapezoid to the area of the rectangle to find the total area: 50 in²+34 in²=84 in²

What is the value of y in the equation, 5x+2y=20, when x=0.3

gregori [183]

Answer:

y = -5/2x + 10

Step-by-step explanation:

Step one: Add -5x to both sides.

5x + 2y + -5x = 20 + -5x

2y = -5x + 20

Step two: Divide both sides by two.

2y/2 = -5x + 20/ 2

y = -5/2x + 10

Hope my answer help.

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

Amanda [17]

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

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