Part 1) <span>What is the total area of the swimming pool?
</span>
we know that
<span>area of the swimming pool=area rectangle-area semi circle
area rectangle=20*36-----> 720 ft</span>²
area semicircle=pi*r²/2
r=18/2----> 9 ft
area semicircle=pi*9²/2----> 127.17 ft²
area of the swimming pool=720 ft²-127.17 ft²----> 592.83 ft²
the answer Part 1) is
The area of the swimming pool is 592.83 ft²
Part 2) <span>What is the perimeter of the swimming pool?
</span>
perimeter of the swimming pool=perimeter of rectangle-18 ft+perimeter semi circle
perimeter of rectangle=2*[20+36]---> 112 ft
perimeter semi circle=2*pi*r/2----> pi*r
r=9 ft
perimeter semi circle=pi*9----> 28.26 ft
so
perimeter of the swimming pool=112 ft-18 ft+28.26 ft----> 122.26 ft
the answer Part 2) is
122.26 ft

The general formula for a equation of the form:
is:
In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:
then:
and
Therefore, x=3 or x=1.
Answer:
Answer 1: a. Moonlight: C=75n+1000
Riverside: C=50n+1500
Answer 2: c. The solution coordinates are c. (20, 2500)
Answer 3: c. When there are 20 guests attending the price is $2500.
Step-by-step explanation:
Moonlight Hall:
Fixed cost = $1000
Cost per guest = $75
Cost of <em>'n' </em>guests = 75
Total cost of moonlight hall = Fixed cost + Cost of 'n' guests
Riverside Hall:
Fixed cost = $1500
Cost per guest = $50
Cost of <em>'n' </em>guests = 50
Total cost of moonlight hall = Fixed cost + Cost of 'n' guests
Hence, Answer 1:
a. Moonlight: C=75n+1000
Riverside: C=50n+1500
Answer 2: Coordinates of solution:
Option c. (20,2500) satisfies both the equation.
When there are 20 number of guests, the cost of both moonlight and riverside hall comes out to be 2500.
Moonlight Hall cost
Riverside Hall cost
Answer 3: c. When there are 20 guests attending the price is $2500.
The solution is done in Answer 2.
So,
Answer 1: a. Moonlight: C=75n+1000
Riverside: C=50n+1500
Answer 2: c. The solution coordinates are c. (20, 2500)
Answer 3: c. When there are 20 guests attending the price is $2500.
