$80.5 is the right answer.
We divide 3500 by 100 and then multiply the answer to 2.3

A line has a slope of -2/5 and passes through the point (10,7) . Write the equation of this line in point-slope form, slope-inte

qaws [65]

$(\stackrel{x_1}{10}~,~\stackrel{y_1}{7})\hspace{10em} \stackrel{slope}{m} ~=~ -\cfrac{2}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{7}=\stackrel{m}{-\cfrac{2}{5}}(x-\stackrel{x_1}{10})$

Find the area of each figure. Round to the nearest hundredth where necessary. Only 1 and 5 please!

Alex787 [66]

Answer:

See below

Step-by-step explanation:

To begin, it is volume, not area

1. 8 x 12 x 17 = 1632 in ^3

5. 9 x 9 x 13.5 = 1093.5 in^3

If you want to find SURFACE AREA:

1. 2(8 x 12) + 2(8 x 17) + 2(17 x 12) = 872 in^2

5. 2(9 x 9) + 4(9 x 17) = 774 in^2

An FM radio station signal travels in a 40-mile radius. An AM radio station

MrMuchimi

Answer:

4976.28 square miles (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}$

<u>FM radio station</u>

Given:

r = 40 miles

$\implies \textsf{Area}=\pi (40)^2=1600 \pi \: \sf miles^2$

<u>AM radio station</u>

Given:

r = 4 miles

$\implies \textsf{Area}=\pi (4)^2=16 \pi \: \sf miles^2$

Difference:

$\begin{aligned}\implies \textsf{FM area - AM area} & =1600 \pi - 16 \pi\\ &= 1584 \pi\\ & =4976.23\:\textsf{square miles (nearest hundredth)}\end{aligned}$
