A hotel swimming pool is made up of four semicircles and a square. Find the perimeter of the swimming pool. Round your answer to the nearest tenth. The perimeter is about yards.

Answers

Answer 1

Answer:

75.4yd

Step-by-step explanation:

Find the diagram attached

Perimeter of the figure = perimeter of the 4 semicircles

Perimeter of a semicircle = πd/2

d is the diameter of the semicircle = 12yd

Perimeter of a semicircle = 3.14(12)/2

Perimeter of a semicircle = 37.68/2

Perimeter of a semicircle = 18.94yd

Perimeter of the 4 semicircles = 4 * 18.94

Perimeter of the 4 semicircles = 75.36yd

Hence the perimeter of the swimming pool to nearest tenth is 75.4yd

What’s the question?

Answer:

Step-by-step explanation:

3. A soccer player heads a ball from a height of 6 feet with an initial vertical velocity of 20 feet per second. The height h in feet of the ball is given by h= –16t + 20t +6,
where t is the time elapsed in seconds. How long will it take the ball to hit the
ground if no other players touch it? State the method you used to solve this
quadratic equation and why you chose that method.

Answers

Answer:

Part A

1.5 seconds

Part B

By substitution and factorization because h = 0 at ground level

Step-by-step explanation:

Part A

The height from which the soccer player heads the ball, h = 6 feet

The initial velocity of the ball, v = 20 ft./s

The height of the ball in feet, h = -16·t² + 20·t + 6

From the given equation of the ball, we have;

At the initial height, t = 0, from the given equation, h = 6

At the ground level, the height, h = 0, therefore, we get;

0 = -16·t² + 20·t + 6

Factorizing using a graphing calculator gives;

0 = 2 × (-8·t² + 10·t + 3) = -2 × (8·t² - 10·t - 3) = -2 × (2·t -3)·(4·t + 1)

∴ (2·t -3)·(4·t + 1) = 0

t = 1.5 or t = -1/4 = -0.25

Therefore;

The time it takes the ball to hit the ground, t = 1.5 seconds.

Part B

The method used in solving the given quadratic equation is by plugging in the value of 'h' as h = 0 in the given equation and factorizing the result because at ground level, the height, h = 0.

Charlene owns a bookstore. She purchases used books from customers. • She pays $3.50 for each hardback book. • She pays $0.75 for each paperback book. • Charlene pays a customer a total of $199.75 for 149 used books. Which system of equations could be used to determine the number of hardback books (x) and the number of paperback books (y) Charlene purchases from the customer?

Answers

Answer: Number of hardback = 32

Number of paperback = 117

Step-by-step explanation:

Let the number of hardback books be represented by x.

Let the number of paperback books be represented by y.

Based on the information given, we can form an equation which will be:

x + y = 149 ......... i

3.50x + 0.75y = 199.75 ...... ii

Multiply equation i by 3.50

Multiply equation ii by 1

3.50x + 3.50y = 521.50 ...... iii

3.50x + 0.75y = 199.75 .....iv

Subtract equation iv from iii

2.75y = 321.75

y = 321.75 / 2.75

y = 117

Number of paperback = 117

Since x + y = 149

x = 149 - y

x = 149 - 117

x = 32

Number of hardback = 32

A pocket contains 2 pennies, 2 nickels, 1 quarter and 4 dimes. What is the probability of randomly choosing a dime two times in a row, if the first coin drawn is not replaced?

Answers

Answer:

1/6

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability of choosing dimes twice = total number of dimes / total number of coins

At first pick = 4/9

because there is no replacement, dimes and total coins reduce by 1 and

second pick = 3/8

4/9 x 3/8 = 1/6

For what value of x is the equation 2x−3-x+4=3 true?

Answers

Answer:

Step-by-step explanation:

2x−3-x+4=3

x + 1 = 3

x = 2

The equation is true for the value of x = 2.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is as given below.

2x − 3 - x + 4 = 3

We have to operate the like terms together.

Here 2x and x are like terms and 3 and 4 are like terms.

(2x - x) - 3 + 4 = 3

x - 3 + 4 = 3

x + 1 = 3

Subtracting 1 on both sides,

x = 3 - 1

x = 2

Hence the equation is true for x = 2.

What is the coordinates of the focus for the following parabola -8(x-5)=(y+1)^2

Answers

By definition of the focus of a parabola, the coordinates of the focus of the parabola - 8 · (x - 5) = (y + 1)² are represented by the point F(x, y) = (3, - 1). (Correct choice: A)

How to locate the focus of a parabola

The standard equation of the parabola with an horizontal axis of symmetry is presented below:

[tex]x - h = \frac{1}{4\cdot p}\cdot (y - k)^{2}[/tex] (1)

Where:

h, k - Vertex of the parabola.p - Distance between the vertex and the focus.

The coordinates of the focus is described by the following expression:

F(x, y) = (h + p, k)

If we know that h = 5, k = - 1 and p = - 2, then the coordinates of the focus are:

F(x, y) = (5 - 2, - 1)

F(x, y) = (3, - 1)
