7% of $35 is $2.45. If you want to get the price after you've found out what you've taken away, it'd be $32.55.

<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Anyway, I'll help you either way. A sector is a region of a circle between two radii. Let's assume the sector as:

$s=25\pi cm^2$

Then, we can find the central angle by the following equation:

$s=\frac{\theta}{360}\times\pi r^{2} \\ \\ r=10cm \\ \\ s=25\pi cm^2 \\ \\ \\ So: \\ \\ \frac{25\pi(360)}{10^2\pi}=\theta \\ \\ \theta = 90^{\circ}$

But:

$90^{\circ}=\frac{\pi}{2}$

Then:

$C:Perimeter \ of \ sector \\ \\ \\ C=\theta r \\ \\ C=\frac{\pi}{2}(10) \\ \\ C=5\pi cm \approx \boxed{15.7cm}$

Lyle purchased a motorcycle for $13,430. It depreciates about 4.1% each year. What is the value of the motorcycle after seven ye

erma4kov [3.2K]

Answer:

$\$10,018.58$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$13,430\\r=4.1\%=0.041\\x=7\ years$

substitute the values

$V=\$13,430(1-0.041)^{7}=\$10,018.58$
