Use the method illustrated in the solutions to Exercise 9.2.39 to answer the following questions. (a) How many ways can the letters of the word DANCER be arranged in a row? Since the letters in the given word are distinct, there are as many arrangements of these letters in a row as there are permutations of a set with elements. So the answer is . (b) How many ways can the letters of the word DANCER be arranged in a row if D and A must remain together (in order) as a unit? (c) How many ways can the letters of the word DANCER be arranged in a row if the letters NCE must remain together (in order) as a unit?

Answer:

$15 / hr

$450 / week

Step-by-step explanation:

30 h x 52 w = 1560 hrs

$23400 / 1560 = $15 / hr

$15 * 30 hrs = $450 / week

Answer: 16

Step-by-step explanation:

Let the number of candy Ed took be denoted as "x"

Since Joe ate twice the amount of candy Ed ate, then the number of candies joe ate will be denoted as "2x"

Since all together they ate a total of 48 candies, then the sum of the candies eaten by Joe and Ed is what gives a total of 48

This means:

2x + x = 48

3x = 48

X = 16.

Answer:

tha answer is B

Step-by-step explanation:

g would be 125 degrees

h would be 62 degrees

Answer:

g = 118°

Step-by-step explanation:

b = 180 - 62 = 118 because b is supplementary to the 62° angle

g = 118 because b and g are alternate interior angles

Answer:

[tex]\boxed {\boxed {\sf 19.625 \ ft^2}}[/tex]

Step-by-step explanation:

The area of a circle is found using this formula:

[tex]a= \pi r^2[/tex]

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

[tex]a= (3.14)* (2.5 \ ft)^2[/tex]

Solve the exponent.

[tex]a= (3.14)*(6.25 \ ft^2)[/tex]

Multiply.

[tex]a=19.625 \ ft^2[/tex]

The area of the circle is 19.625 square feet.

Answer:

y = 5 x + ln ( x − 2 )

Answer:

- 1.5

Step-by-step explanation:

Given points

( x1 , y1 ) = ( 4 , - 5 )

( x2 , y2 ) = ( - 2 , 4 )

Now

Slope (m)

= ( y2 - y1 ) / ( x2 - x1 )

= ( 4 + 5 ) / ( - 2 - 4 )

= 9 / - 6

= -1.5

Answer:

  3 3/4 cups

Step-by-step explanation:

The yield from 3/4 cup of sugar is 2 dozen cookies. Multiply that by 5 and you get: the yield from 15/4 cups of sugar is 10 dozen cookies.

As a mixed number 15/4 = 3 3/4.

Ana will need 3 3/4 cups of sugar for 10 dozen cookies.

Answer:

Solution given:

recipe use 3/4 cup of sugar for 24 or 2 dozen Cooke's

2 dozen=3/4 cup of sugar

10dozen=3/4×10/2=15/2 cup of sugar is needed

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center [tex](x_0,y_0)[/tex] is given by:

[tex]\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1[/tex]

In this question, we have that:

[tex]-x_0 = -1 \rightarrow x_0 = 1[/tex]

[tex]-y_0 = 3 \rightarrow y_0 = -3[/tex]

The coordinates of the center of the hyperbola are (1,-3)

Answer:

probability: 0.44

The probability that a student chosen at random will be 16 or older is 0.44 or 44%.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The probability that a student chosen at random will be 16 or older is the sum of the probabilities of selecting a 16-year-old or older student.

P(16 or older) = P(16) + P(17) + P(18)

P(16 or older) = 0.28 + 0.15 + 0.01

P(16 or older) = 0.44

Therefore, the probability that a student chosen at random will be 16 or older is 0.44 or 44%.

Step-by-step explanation:

The x component must be positive (3)

Answer:

6.3 years

Step-by-step explanation:

Given

[tex]P = 22400[/tex] --- initial value

[tex]r = 12\%[/tex] -- rate

[tex]A = P(0.88)^t[/tex] --- function

Required

Find t when [tex]A = 10000[/tex]

We have: [tex]A = P(0.88)^t[/tex]

Substitute: [tex]A = 10000[/tex] and [tex]P = 22400[/tex]

[tex]10000 = 22400 * 0.88^t[/tex]

Divide both sides by 22400

[tex]0.4464 = 0.88^t[/tex]

Take log of both sides

[tex]\log(0.4464) = \log(0.88^t)[/tex]

Apply law of logarithm

[tex]\log(0.4464) = t\log(0.88)[/tex]

Solve for t

[tex]t = \frac{\log(0.4464)}{\log(0.88)}[/tex]

[tex]t = \frac{-0.3503}{-0.0555}[/tex]

[tex]t = 6.31[/tex]

[tex]t \approx 6.3[/tex]

y > x

y > x+2

y>x and y>x+2 is the  systems of inequalities describes the shaded region in the graph below.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade.

If the symbol ≥ or > is used, shade above the line.

If the symbol ≤ or < is used shade below the line.

y>x and y>x+2 is the inequality describes the shaded region in the graph below as it is greater.

Hence, y>x and y>x+2 is the  systems of inequalities describes the shaded region in the graph below.
