constructing a border around a pool a circular pool measures 10 feet across. one cubic yard of concrete is to be used to create

Paha777 [63]

Answer:

We get w = 1.508 feet.

Step-by-step explanation:

Let w be the width of the border.

The diameter of the pool will be 10 feet.

The depth will be 3 inches. So, we will convert it to feet.

3 inches = $\frac{3}{12}=0.25 feet$

The circular area including pool and the border, radius = $(w+5)$

Border area = Total area - pool area

= $\pi (w+5)^{2} -\pi (5)^{2}$

Putting pi = 3.14 and solving the expression we get the following equation:

$3.14w^{2}+31.4w-53.5$

As given one cubic yard of concrete is to be used, this is the volume to be used.

1 cubic yard = 27 cubic feet

Now using the volume given and thickness of this area that is 0.25 feet.

$0.25(3.14w^{2}+31.4w-53.5) =27$

$=> 0.785w^{2}+7.85w-13.375-27= 0$

$=> 0.785w^{2}+ 7.85w-13.625= 0$

Solving this quadratic equation, we get w = 1.508 feet and w = -11.508 feet.

Neglecting the negative value, we get w = 1.508 feet.

A waiter earns $128 for six hours of work. The total included $86 in tips. How much does the waiter earn each hour??A waiter arm

Lady bird [3.3K]

Answer:

The waiter earns $7 per hour

Step-by-step explanation:

In this question, we are asked to calculate the amount a waiter earns per hour at work given the total he had earned including tips.

To solve this question, we can see that we have been given the total amount he has earned and also the amount he has also earned in tips.

Now, to get the standard amount he’s supposed to earn per hour, firstly, we have to subtract the amount he has earned in tips from the total. Mathematically that is 128-86 = $42

This means, by standard he has earned $42 in six hours. Now, we need to calculate the amount she earns by hour.

To do this, we simply divide the total amount earned by the number of hours.

Mathematically that is $42/6 hours = $7 per hour

Answer: $-\frac{3}{16}$

Step-by-step explanation:

$\frac{3}{4}(-\frac{1}{4} )$

multiply the numberator and denominator:

3*-1 = -3

and

4*4 = 16 so,

$-\frac{3}{16}$ is the answer
