The tree statements of the circle are

1) The radius of the circle is 3 units.

2) The center of the circle lies on x-axis.

3) The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

What is center of a circle?

A circle's center is the point from which all of the distances to the other points on the circle are equal. The radius of the circle is the measurement at issue.

Given equation of circle is

x² + y² - 2x - 8 =0

x² - 2x + 1 - 1 + y² - 8 =0

(x - 1)² - 1 + y² - 8 =0

(x - 1)² + y² - 9 =0

(x - 1)² + y² = 3²

Compare the equation above equation with (x - h)² + (y - k)² = r²:

h = 1, k=0, r=0

The radius of the circle is 3 units. The center of the circle is (1,0) which lies on the x-axis.

Rewrite the equation of circle x² + y² = 9:

x² + y² = 3²

The number of nickels is 173.

The number of dimes is 258.

The number of quarters is 69.

The coins are worth $51.7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

For every 2 nickles, there are 3 dimes.

For every 2 dimes, there are 5 quarters.

This means,

Let,

Nickles = N

Dimes = D

Quarters = Q

2N = 3D

N = 3D/2

2D = 5Q

Q = 2D/5

Now,

N + D + Q = 500

3D/2 + D + 2D/5 = 500

15D + 10D + 4D = 500 x 10

29D = 5000

D = 5000/29

D = 173

Now,

N = 3 x 172 / 2

N = 3 x 86

N = 258

Q = 2 x 172 / 5

Q = 69

Now,

Total coins = 500

173 + 258 + 69 = 500

Now,

20 nickels = $1

10 dimes = $1

4 quarters = $1

So,

173 nickels = $1 x 173 / 20 = $8.65

258 dimes = $1 x 258 / 10 = $25.8

69 quarters = $1 x 69 / 4 = $17.25

The total worth.

= $8.65 + $25.8 + $17.25

= $51.7

Thus,

The number of nickels is 173.

The number of dimes is 258.

The number of quarters is 69.

The coins are worth $51.7.

There are 144 ways to place 4 pairs of shoes per shelf in the store.

What is a permutation?

The term permutation refers to a mathematical calculation of the number of ways a particular set can be arranged. Put simply, a permutation is a word that describes the number of ways things can be ordered or arranged. With permutations, the order of the arrangement matters.

This question can be solved using basic logic . One can also solve this by using permutations.
Since 12 different models arrive and 4 pairs of shoes should be placed per shelf , the answer can be sort by

4!×3! = [ 4×3×2×1] × [3×2×1] = 24×6 = 144.

( Because 4 pairs of shoes can be interchanged among themselves , therefore 4! , and 12/4=3 , so the 12 pair of shoes can be organised amongst 3 shelves , and hence 3!)
Therefore , none of the options is correct. The correct answer is 144 ways.

Answer:

2700

Step-by-step explanation:

1st method:

let x be the number of all workers in the company

then, the number of female workers will be x-0.85x = 0.15x

0.15x = 405

x = 405/0.15 = 2700

2nd method

we know that the 405 people who aren't men make 15% (100%-85%) of the whole number of workers, by using proportions:

15% - 405

100% - X

X = (100% * 405 )/15% = 2700

D. At the end of 20 years, the policy's cash value will equal $100,000 is INCORRECT regarding a $100,000 20-year level term policy.

A $100,000 20-year level term policy is a type of life insurance policy that provides a fixed amount of coverage for a set period of time. The premiums for this policy will remain level for the entire 20 years and, if the insured dies during that time, the beneficiary will receive the full $100,000. However, the policy will expire at the end of the 20-year period and the cash value will not equal the $100,000.

Answer:

y = 1.50x

the graph is shown below

Step-by-step explanation:

We are told that y is equal to the total cost of the amount of grapefruit purchased. The amount of grapefruit is represented by x. The price of $1.50 would be our rate or slope for the graph.

With this information, we can create the expression:

y = 1.50x

To find the graph you need, either type it in a graphing calculator, or put in your choice of "x" values to find different coordinate that would be on the graph.

For example:

y = 1.50(2)

y = 3

Coordinate 1 would be (2,3)

y = 1.50(0)

y = 0

Coordinate 2 would be (0,0)

With these two coordinates you can draw a line and match your graph with the right one you need for the answer.

1. Move 12 to the right side.

2. Divide both sides by -7.

3. Simplify.

4. Square both sides.

5. Solve [tex]x-5=\frac{64}{49}[/tex]

Based on the provided table and equation when the class size is 1, gymnastics is less expensive, and when the class size is 3 or 4, ice skating is less expensive.

Given that y denotes the price and x denotes the number of classes, the gymnastics programmed is completed by the table, whereas the ice skating program is concluded by the equation y = 18x + 20.

Find the cost of the ice skating programmed for classes 1, 2, 3, and 4 as the table already lists the price for each specified number of gymnastics courses.

For 1 class, substitute x = 1 into y = 18x + 20:

y = 18(1) + 20

y = $38

For 2 class, substitute x = 2 into y = 18x + 20:

y = 18(2) + 20

y = $56

For 3 class, substitute x = 3 into y = 18x + 20:

y = 18(3) + 20

y = $74

For 4 class, substitute x = 4 into the equation y = 18x + 20:

y = 18(4) + 20

y = $92

We may infer from the foregoing that gymnastics is less expensive when the number of lessons is 1. When there are three or four courses, ice skating is less expensive.

Step-by-step explanation:

Therefore, the value of the given equation of  x comes out to be  x =5.

Equations can be classified as either identities or conditioned equations. For each amount of the variables, an identity is true. Only specific values of the variables make a conditional equation legitimate. The equality sign ("="), which separate the two expressions, is a symbol for an equation.

Here,

Given data: A, B, and C are parallel, B is located between A and C, AC equals 24, AB equals 2x+1, and BC equals 3x-2.

In the event where A, B, and C are collinear and B is positioned between A and C, we obtain

Replace the given equation with AC = 24, AB = 2x+1, and BC = 3x-2.

AB plus BC equals AC

=>  AC= AB + BC

On combining like terms we get

=> 2x+1 + 3x-2 = 24

=> 5x -1 =24

=>5x =25

=>x =5

Therefore, the value of x comes out to be  x =5.

Answer:

there should be 1 customer waiting in line at the ticket outlet.

Step-by-step explanation:

To calculate the expected number of customers in the queue, we can use the following formula:

Expected number of customers = Arrival rate * Average waiting time

In this case, the arrival rate is 10 customers per hour and the average waiting time is 6 minutes. Converting the waiting time to hours, we get:

Expected number of customers = 10 customers/hour * (6 minutes / 60 minutes/hour) = 1 customer

So the expected number of customers in the queue is 1. This means that on average, there should be 1 customer waiting in line at the ticket outlet.
