Answer:  The required discount is $819  and  the rate of discount is 20.48%.

Step-by-step explanation:  Given that a home theater system is marked down from $3999 to $3180.

We are to find the discount and the rate of discount.

The discount will be given by actual price minus the marked price.

We have

Actual price = $ 3999  and  marked price = $3180.

So, the discount is given by

\textup{Discount}=\$(3999-3180)=\$819

And the rate of discount is

\textup{Rate of discount}=\dfrac{819}{3999}\times100\%=20.48\%

Thus, the required discount is $819  and  the rate of discount is 20.48%.

Answer:819,20.48 %

Step-by-step explanation:

Initial price=3999

Final price=3180

Discount is given by

=initial price - Final price

=3999-3180=819

Rate of interest is given by \frac{initial -final }{initial }

=\frac{3999-3180}{3999}=0.2048

i.e. 20.48 \%

What is the angle measure of an arc bounding sector with an area of 5pie square miles?
Snowcat [4.5K]

if the diameter is 20, the its radius must be half that or 10.

\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=5\pi \\ r=10 \end{cases}\implies \begin{array}{llll} 5\pi =\cfrac{\theta \pi (10)^2}{360}\implies 5\pi =\cfrac{5\pi \theta }{18} \\\\\\ \cfrac{5\pi }{5\pi }=\cfrac{\theta }{18}\implies 1=\cfrac{\theta }{18}\implies 18=\theta \end{array}

Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. Write your answer in terms of pi, and be su
Ksju [112]

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

Area= 2\pi r(r+h)

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

Area= 2\pi *4(4+3)

Area= 2\pi *4(7)

Area= 2\pi *28

Area= 56\pi

Hence final answer is

Area= 56\pi square ft
