Answer:

perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th

Step-by-step explanation:

The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π

Both semicircles together have a length of 5π + 5π = 10π

The radius of the 1/4 circle is 10, so the diameter is 20

The length of the 1/4 circle's arc is 1/4 times the circumference of its circle

So, the length of that arc is 1/4π(20) = 5π

Now the perimeter of the fountain is 10π + 5π = 15π

The price of a new computer is $1,449 at your local store. This is 18% less than what it costs at the Brownstone Mall. How much

Komok [63]

Given:

Price of new computer at local store = $1,449

This is 18% less than what it costs at the Brownstone Mall.

To find:

The cost of new computer at the Brownstone Mall.

Solution:

Let x be the cost of new computer at the Brownstone Mall.

According to the question,

$x-18\%\text{ of }x=1449$

$x-\dfrac{18}{100}x=1449$

$x-0.18x=1449$

$0.82x=1449$

Divide both sides by 0.82.

$x=\dfrac{1449}{0.82}$

$x=1767.07317$

$x\approx 1767.07$

Therefore, the cost of new computer at the Brownstone Mall is $1767.07.
