Beth buys a flute for $400 and pays 6% sales tax. What is the total price she pays for the flute?

Answer:

x=8

Step-by-step explanation:

The vertical asymptote is where the denominator goes to zero

3(x-8) =0

Divide by 3

(x-8) =0

Add 8 to each side

x-8+8=0+8

x=8

The vertical asymptote can be find by solving the 0 of the denominator.

3(x - 8) = 0

3x - 24 = 0

3x - 24 + 24 = 0 + 24

3x = 24

3x/3 = 24/3

x = 8

Ms. Joseph saves money for 12 weeks, starting with $1 and increasing the amount by $1 each week. By the 12th week, she adds $12. Therefore, she saves money for a total of 12 weeks.

To determine how many weeks Ms. Joseph is saving money, we need to look at the pattern of her savings. Each week, she adds one more dollar than the previous week:

We can see that this is an arithmetic sequence where the first term (a) is $1 and the common difference (d) is $1. The nth term of an arithmetic sequence can be found using the formula: aₙ = a + (n-1)d.

For 12 weeks, the amount saved each week would be: a₁₂= 1 + (12-1) ×1 = 12. Ms. Joseph adds $12 in the 12th week. Finally, the total weeks she saves money is 12 weeks.

25 % of the water had evaporated.

Answer:

20%

Step-by-step explanation:

Since the total amount of water is 2.5 million

And 2 million evaporated,

To determine the amount left,it will be total amount- evaporated

2.5-2=0.5

To determine the% of evaporated water

Final answer:

The equilibrium price for the Seattle Mariners baseball team's seats can be found using economic principles of supply and demand, taking into account factors that influence ticket demand, marginal revenue, and costs.

Explanation:

The question involves determining the equilibrium price for Seattle Mariners baseball team seats. This can be addressed using principles from Economics, specifically the supply and demand model. To determine the equilibrium price, one would need to establish the demand curve, which includes factors such as the population and income of the home city, the team's standing, and the number of superstars on the team. As economists such as Ferguson et al. suggest, the marginal cost for sports teams is often assumed to be zero due to the fixed costs of stadium operations. Therefore, the profit-maximizing quantity of seats sold is where marginal revenue is zero. This can be calculated and visualized with a graph showing both demand and marginal revenue curves. Additionally, adjustments such as the addition of new seats or external fees like licensing can affect the equilibrium dynamics, thus changing the equilibrium price and the total revenue.

Answer:

The probability of a student to be in the orchestra or the band is 0.07 or 7%.

Step-by-step explanation:

The probability of a student to be in the orchestra or the band is given by the following formula:

p(orchestra or band) = p(orchestra) + p(band) - p(orchestra and band)

p(orchestra or band) = 0.03 + 0.05 - 0.01

p(orchestra or band) = 0.08 - 0.01

p(orchestra or band) = 0.07

The probability of a student to be in the orchestra or the band is 0.07 or 7%.

Final answer:

The probability that a student is in orchestra or band is 7%.

Explanation:

To calculate the probability that a student at Lincoln High School is in either orchestra or band, we will use the formula for the probability of the union of two events, P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A) is the probability of being in orchestra, P(B) is the probability of being in band, and P(A ∩ B) is the probability of being in both orchestra and band.

In this case, we have been given that 3% of students are in orchestra, 5% are in band, and 1% are in both.

Therefore, we have:

Applying the formula:

P(orchestra OR band) = P(orchestra) + P(band) - P(both orchestra and band) = 0.03 + 0.05 - 0.01 = 0.07

Therefore, the probability that a student is in either the orchestra or the band is 7%.

Answer:

63/380

Step-by-step explanation:

Initially,

# of Mysteries, M = 9

# of Biographies, B = 7

# of Sci. Fiction, S = 4

Total number of books = 9 + 7 + 4 = 20 books

P (first book selected is biography) = 7/20

After selecting 1 biography book,

# of Mysteries, M = 9

# of Biographies, B = 7 - 1 = 6

# of Sci. Fiction, S = 4

Total number of books remaining = 9 + 6 + 4 = 19 books

P (second book selected is a mystery) = 9/19

Hence (P first book is biography and 2nd book is mystery)

= (7/20 )(9/19)

= 63/380

The probability of selecting a biography then a mystery is 0.14.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a bookshelf contains 9 mysteries, 7 biographies, and 4 science fiction books.

Total number of outcomes = 9+7+4

= 20

The probability of selecting a biography = 7/20

The probability of selecting a mystery = 9/20

Probability of an event = 7/20 × 9/20

= 56/400

= 0.14

Therefore, the probability of selecting a biography then a mystery is 0.14.

Answer:

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

[tex]x^{2} +x^{2}[/tex] = 72

2[tex]x^{2}[/tex] = 72. Divide both sides by 2

[tex]x^{2}[/tex] = 36.  Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 +[tex]\sqrt{72}[/tex] = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397 [tex]cm^{2}[/tex]

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4 [tex]cm^{3}[/tex]

Final answer:

The surface area of the triangular prism can be calculated by finding the areas of the two triangular bases and the three rectangular sides. After calculations, the total surface area of the prism is found to be 2304 square centimeters.

Explanation:

The question asks us to find the surface area of a triangular prism whose base is an isosceles right triangle with a hypotenuse of √72 centimeters and a height of 7 centimeters. We'll use various formulas for geometry, area, and volume to solve this problem.

First, we need to find the legs of the isosceles right triangle which form the base of the prism. Since it is a right triangle, and the legs (a) are equal, we can use Pythagoras' theorem where [tex]a^2 + a^2 = (72)^2[/tex]

Solving this gives us each leg as 36 cm.

The area of the base triangle is then found using 1/2 × base × height, which gives us-

1/2 × 36 × 36 = 648 square centimeters

The prism has two such triangular bases, so their combined area is 2 × 648 = 1296 square centimeters.

For the three rectangular sides, we calculate their areas by using the formula for the area of a rectangle (length × width). Each side has a length of 7 cm (the height of the prism). The widths are equal to the sides of the triangular base: 36 cm, 36 cm, and √(362 + 362) = √2592 = 72 cm. Thus, the total area of these sides is-

2(36 × 7) + (72 × 7) = 504 + 504 = 1008 square centimeters.

The total surface area of the prism is the sum of the areas of the bases and the rectangular sides, which is 1296 + 1008 = 2304 square centimeters.

Answer:

71 and -35

Step-by-step explanation:

so with this we can set up a system of equations

x+y=36

and

x-y=106

now we can add these equations together to eliminate y

x+y=36 plus

x-y=106 equals

2x=142

divide both sides by 2

x=71

now we can plug that in

71+y=36

subtract 71 from both sides

y=-35

Answer:

-71 and

35

Step-by-step explanation:

Let the numbers be x and y

x + y = -36

x = y - 106

Substitute y - 106 or x in the first equation

We have

x + y = -36

y - 106 + y = -36

y + y - 106 = -36

2y - 106 = -36

Add 106 to both sides to eliminate -106 on the left side

2y - 106 + 106 = -36 + 106

2y = 70

Divide both sides by 2

2y/2 = 70/2

y = 35

Substitute 35 for y in either equation to get x

Using the second equation, we have

x = y - 106

x = 35 - 106

x = -71

The numbers are 35 and -71

Check

x + y = -36

-71 + 35 = -36

-36 = -36

Final answer:

To find the value that goes in the empty cell, we need to multiply each value of x by 5. So, when x = -1, f(x) = 5*(-1) = -5. Therefore, the value that goes in the empty cell is -5.

The table represents the function f(x) = 5x. In the first column, we have the values of x, which are -1, 0, 1, and 2. In the second column, we have the values of f(x), which are blank, 0, 5, and 10. To find the value that goes in the empty cell, we need to multiply each value of x by 5. So, when x = -1, f(x) = 5*(-1) = -5. Therefore, the value that goes in the empty cell is -5.

Final answer:

To find the number of different arrangements of president, vice-president, and secretary in a club of 11 members, we use the concept of permutations. Using the formula for permutations of distinct objects, we calculate P(11,3) = 990. Thus, there are 990 different arrangements possible.

Explanation:

To find the number of different arrangements of president, vice-president, and secretary, we can use the concept of permutations. Since the positions have different roles and can only be assigned to one person each, we use permutations. The number of permutations can be found using the formula for permutations of distinct objects: P(n,r) = n! / (n-r)!.

In this case, we have 11 members and need to assign them to 3 different positions (president, vice-president, and secretary). So, the number of arrangements is P(11,3) = 11! / (11-3)! = 11! / 8! = 11 x 10 x 9 = 990.

Therefore, there are 990 different arrangements of president, vice-president, and secretary possible.
