A rectangular swimming pool is twice as long as it is wide. A small concrete walkway surrounds the pool. The walkway is a 2 feet

Ksivusya [100]

Answer:

The width and the length of the pool are 12 ft and 24 ft respectively.

Step-by-step explanation:

The length (L) of the rectangular swimming pool is twice its wide (W):

$L_{1} = 2W_{1}$

Also, the area of the walkway of 2 feet wide is 448:

$W_{2} = 2 ft$

$A_{T} = W_{2}*L_{2} = 448 ft^{2}$

Where 1 is for the swimming pool (lower rectangle) and 2 is for the walkway more the pool (bigger rectangle).

The total area is related to the pool area and the walkway area as follows:

$A_{T} = A_{1} + A_{w}$ (1)

The area of the pool is given by:

$A_{1} = L_{1}*W_{1}$

$A_{1} = (2W_{1})*W_{1} = 2W_{1}^{2}$ (2)

And the area of the walkway is:

$A_{w} = 2(L_{2}*2 + W_{1}*2) = 4L_{2} + 4W_{1}$ (3)

Where the length of the bigger rectangle is related to the lower rectangle as follows:

$L_{2} = 4 + L_{1} = 4 + 2W_{1}$ (4)

By entering equations (4), (3), and (2) into equation (1) we have:

$A_{T} = A_{1} + A_{w}$

$A_{T} = 2W_{1}^{2} + 4L_{2} + 4W_{1}$

$448 = 2W_{1}^{2} + 4(4 + 2W_{1}) + 4W_{1}$

$224 = W_{1}^{2} + 8 + 4W_{1} + 2W_{1}$

$224 = W_{1}^{2} + 8 + 6W_{1}$

By solving the above quadratic equation we have:

W₁ = 12 ft

Hence, the width of the pool is 12 feet, and the length is:

$L_{1} = 2W_{1} = 2*12 ft = 24 ft$

Therefore, the width and the length of the pool are 12 ft and 24 ft respectively.

I hope it helps you!

What is the value of f (x)=16^x when x=1/2 ? A. 2 B. 4 C. 8 D. 32

Cerrena [4.2K]

Answer:

Step-by-step explanation:

Using the rule of exponents

$a^{\frac{m}{n} }$ ⇔ $\sqrt[n]{a^{m} }$

Given

f(x) = $16^{x}$ , then when x = $\frac{1}{2}$

f( $\frac{1}{2}$ ) = $16^{\frac{1}{2} }$ = $\sqrt[2]{16}$ = 4

Over a 10 year period, there were a total of 246 unprovoked shark bites in Florida. Assuming that shark bites occur at the same

Serggg [28]

Answer: Our required probability is 0.067.

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of years = 10

So, Number of days in 10 years = 365 × 10 = 3650

Number of unprovoked shark bites in Florida = 246

so, Probability that there will be at least one unprovoked shark bite on a given day is given by

$\dfrac{246}{3650}\\\\=0.067$

Hence, our required probability is 0.067.
