A rectangular swimming pool has a perimeter of 96 ft. The area of the pool is 504 ft2. Which system of equations models this sit

gregori [183]

Answer:

2l + 2w = 96 ..... eqn1

lw = 504 ...... eqn2

Step-by-step explanation:

To model this case where we have two unknowns l and w, we need two equations.

Firstly, the perimeter of a rectangle is given by

2l + 2w = p

Where l,w and p are length, width and perimeter of the rectangle respectively.

Hence,

2l + 2w = 96 ... eqn1

Secondly, the area of a rectangle is given by

Length × width = Area

Hence,

l × w = 504

lw = 504 ... eqn2

With these two equations the solutions to the length and width of the rectangular pool can be derived.

The answer is b. you just multiply the 2 sides of both rectangles to get (6x^2+20x+24) for the bigger rectangle and (x^2-4x+3) for the smaller one so then you substract the bigger one from the smaller one to get the answer

Answer:

C. 176.6 Square feet (I think)

Step-by-step explanation:

I tried many different ways and got three of the answers above but I think this is the right one.

The equation to find area of a circular cone base: $A= \pi r^2$

We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: $r = \frac{d}{2}$
Plug in numbers: $r=\frac{15}{2}$ ≈ $7.5$
Use the Area formula now that you have radius: $A=\pi 7.5^2$
Solve and get = $a = 176.71458676$
Looking at the options the closest one to our answer (off by one-tenth) is C.
