Answer: In first question, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

In second question, The goal of $3050 fell by $710

Step-by-step explanation:

1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.

And, all 500 seats are filled for a​ performance.

Therefore, s + d = 500 ------(1)

Also, the price of one adult's  ticket = $8.50

The price of one student's ticket= $5.50

And, their is a revenue of $3050 by selling the tickets.

Thus, 8.50 d + 5.50 s = 3050 --------(2)

By solving the equation (1) and equation (2),

we get, s = 400, d=100

Thus, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

2. According to the question,

s = 2 d  ----- (3)

s + d = 360 -----(4)

By solving equation (3) and (4),

We get, s = 240 and d = 120

thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340

But, the goal is $3050 ( according to the question)

Thus the total fall = 3050 - 2340 = $710

The city cultural center needs to sell 140 adult and 360 student tickets to meet their target revenue of $3050. If they sell 120 adult tickets and 240 student tickets (360 in total), they will fall $710 short of their goal.

In order to help the members of the city cultural center determine how to distribute tickets between adults and students to meet their target revenue, we have to solve a system of linear equations. The two equations we have for the system are 8.50d + 5.50s = 3050 (which represents the relationship between the price of adult and student tickets and the targeted total revenue), and d + s = 500 (which expects all 500 seats to be filled). Solving these equations, we find that d = 140 adult tickets and s = 360 student tickets need to be sold.

For the second part of the question, they sold 120 adult tickets and 240 student tickets, making a total of 360 tickets at one performance. The total revenue generated from these tickets is (120*8.50) + (240*5.50) = 1020 + 1320 = $2340. So, they fell $3050 - $2340  = $710 below the goal.

Answer:

7/20

Step-by-step explanation:

[tex]\frac{11}{20}+x=\frac{9}{10} \\x=\frac{7}{20}[/tex]

Answer:

x=7/20

Step-by-step explanation:

11/20 +x= 9/10

Subtract 11/20 from each side

 11/20-11/20 +x= 9/10-11/20

x = 9/10-11/20

We need a common denominator of 20

x = 9/10 *2/2 - 11/20

x =18/20 -11/20

x = 7/20

Answer:

Figures are objects that have the same shape, but may have different sizes.

Similar figures are figures that have the same shape but different sizes, with corresponding angles equal and side lengths proportional. This mathematical concept can be applied to many real-world and artistic comparisons.

The definition of similar figures in mathematics is that they are figures that have the same shape but may differ in size. This means that corresponding angles of similar figures are equal, and the lengths of corresponding sides are proportional. For example, all circles are similar to each other since they all have the same shape, regardless of their diameter. A real-world example can be seen when comparing photographs of objects that are the same shape but different sizes, such as a large elephant and a small toy elephant. Despite the size difference, if both are scaled versions of each other, they are considered similar figures.

The concept of similarity extends to various fields and contexts. In art analysis, similar figures may refer to recurring shapes or themes within artworks. An understanding of figure-ground perception, as seen in optical illusions like a vase or two faces, also plays on the concept of recognizing similar shapes within different contexts.

6 tons 294 lb ÷ 3071 is approximately equal to 3.97138

To solve 6 tons 294 lb ÷ 3071, we need to first convert everything to the same unit.

Convert tons to pounds:

1 ton = 2000 pounds

6 tons = 6 * 2000 pounds = 12000 pounds

Combine the weight in pounds:

Total weight = 12000 pounds (6 tons) + 294 pounds

Total weight = 12294 pounds

Divide by 3071:

12294 pounds / 3071 = 3.97138

Therefore, 6 tons 294 lb ÷ 3071 is approximately equal to 3.97138

The answer to the question is $12500.

We want to find the value of [tex]x[/tex] in the proportion,

[tex]6:9=x:72[/tex]

We rewrite the ratio on each side of the equation as fractions to obtain,

[tex]\frac{6}{9}=\frac{x}{72}[/tex]

We now multiply both sides of the equation by [tex]72[/tex] to get,

[tex]\frac{6}{9}\times 72=\frac{x}{72}\times 72[/tex]

This simplifies to  

[tex]\frac{6}{1}\times 8=\frac{x}{1}\times 1[/tex]

Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Step-by-step explanation:

Since we have given that

Number of yards of red fabric purchased by Jane = 50

Number of yards of gold fabric purchased by Jane = 110

We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.

For this we will find H.C.F. of 50 and 110.

Factors of 50 = 1, 2, 5, 10, 25, 50.

Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.

So, Highest common factor of 50 and 110 is 10.

So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

Number of yards of red fabric is given by

[tex]\frac{50}{10}=5[/tex]

Number of yards of gold fabric is given by

[tex]\frac{110}{10}=11[/tex]

Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Eddie ordered 8 pizzas and gave each person 3/5 of a pizza. By dividing the total amount of pizza by the amount each person gets, we determine that there are roughly 13 people at the party.

To solve this problem, you have to divide the total amount of pizza by the amount each person gets. Eddie ordered 8 pizzas and he is giving each person 3/5 of a pizza. To find the number of people, you simply divide the total pizza by the pizza each person gets. The calculation would look like this: 8 divided by (3/5) is equal to 8 * (5/3), which is equal to 40/3, roughly 13.33.

Since we can't have a fraction of a person at the party, we would round this down to 13 people.

Show that: [tex]\frac{FB}{FA} = \frac{GC}{AG}[/tex]

Consider [tex]\triangle ABC[/tex] and [tex]\triangle GFA[/tex]

Reflexive property states that the value is equal to itself.

[tex]\angle BAC \cong \angle GAF[/tex] [Angle] {Reflexive property of equality}

Corresponding angles theorem states that if the two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent(i., e equal).

[tex]\angle ABC \cong \angle GFA[/tex] [Angle]

[tex]\angle ACB \cong \angle AGF[/tex] [Angle]

AA Similarity states that the two triangles have their corresponding angles equal if and only if their corresponding sides are proportional.

then, by AA similarity theorem:  

[tex]\triangle ABC \sim \triangle GFA[/tex]

By segment addition postulates:

AB = FA +FB and AC = AG + GC  

Corresponding sides in similar triangles are proportional

Answer:

p(x) = x³ - 7x² + 25x - 39

Step-by-step explanation:

complex roots occur as conjugate pairs, thus

2 + 3i is a root then 2 - 3i is also a root

given x = 3, x = 2 +3i, x = 2 - 3i are roots, then

(x - 3), (x - (2 + 3i))(x - (2 - 3i)) are the factors and

p(x) = a(x - 3)(x - 2 - 3i)(x - 2 + 3i) ← a is a multiplier

let a = 1

p(x) = (x - 3)((x - 2)² - 9i²)

       = (x - 3)(x² - 4x + 4 + 9) → [ i² = - 1 ]

       = (x - 3)(x² - 4x + 13)

       = x³ - 4x² + 13x - 3x² + 12x - 39

       = x³ - 7x² + 25x - 39

Final answer:

The inequality to find the minimum number of weeks Susie needs to babysit to buy the snowboard is 98 + 72w <= 530. After simplifying, we get w <= 6, so option C) w <= 6 is the correct answer.

Explanation:

To find the minimum number of weeks, w, that Susie needs to babysit to purchase the snowboard, we can set up the following inequality:

98 + 72w \<= 530

This inequality represents the initial amount Susie has saved (
98 dollars) plus the amount she will save each week (72 dollars times the number of weeks, w) must be greater than or equal to the cost of the snowboard (
530 dollars).

Subtract 98 from both sides of the inequality:
72w \<= 432

Divide both sides by 72 to solve for w:
w \<= 6

The correct inequality is w \<= 6, meaning Susie needs to babysit for a maximum of 6 weeks to have enough money to buy the snowboard. Therefore, the correct answer is C) w \<= 6.

$34.99/128 = $0.27 per unit

Answer:

The correct option is C.

Step-by-step explanation:

Two figures are congruent if their corresponding sides are congruent.

We know that, reflection, rotation and translation are rigid transformation. It means the size and shape of image and preimage are same. We can say that in rigid transformation, the image and preimage are congruent.

Dilation is not a rigid transformation. It represents enlargement and compression.

If scale factor |k|>1, then it represent enlargement. If scale factor |k|<1, then it represent compression.

In option C, the scale factor is 4. It means the sides of image are 4 times of the preimage.

Therefore option C is correct and the resultant figure of option C  is not congruent to the original figure.

The y intercept is -54/7

Step-by-step explanation:

We can find the slope

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

   = (-2--7)/(-8--1)

   = (-2+7)/(-8+1)

    =5/-7

  = -5/7

We can use the point slope form of the equation to find the equation of the line

y-y1 = m(x-x1)

y--7 = -5/7 (x--1)

y+7 = -5/7 (x+1)

Distribute the -5/7

y+7 = -5/7 x - 5/7

Subtract 7 from each side

y+7-7= -5/7 x -5/7 -7

y = -5/7x -5/7 -7

Get a common denominator of 7

y = -5/7x -5/7 -49/7

y = -5/7x -54/7

This is in the form

y= mx+b, where b is the y intercept

The y intercept is -54/7

"The greatest number of flash cards that Juan can cut out of the piece of cardboard is 12.

To determine the greatest number of flash cards that Juan can cut out of the cardboard, we need to calculate the area of the cardboard and divide it by the area of one flash card.

 Let's denote the dimensions of the cardboard as [tex]\( L \) inches by \( W \)[/tex] inches, and the dimensions of each flash card as [tex]\( l \)[/tex]nches by [tex]\( w \)[/tex] inches. Given that the cardboard is[tex]\( L \times W \)[/tex]inches and each flash card is [tex]\( l \times w \)[/tex]inches, we can calculate the number of flash cards as follows:

 1. Calculate the area of the cardboard: [tex]\( \text{Area}_{\text{cardboard}} = L \times W \).[/tex]

2. Calculate the area of one flash card:[tex]\( \text{Area}_{\text{flash card}} = l \times w \).[/tex]

3. Divide the area of the cardboard by the area of one flash card to find the number of flash cards:[tex]\( \text{Number of flash cards} = \frac{\text{Area}_{\text{cardboard}}}{\text{Area}_{\text{flash card}}} \).[/tex]

 Given that[tex]\( L = 12 \), \( W = 12 \), \( l = 3 \), and \( w = 4 \)[/tex], we can substitute these values into our equations:

 1.[tex]\( \text{Area}_{\text{cardboard}} = 12 \times 12 = 144 \)[/tex]square inches.

2.[tex]\( \text{Area}_{\text{flash card}} = 3 \times 4 = 12 \)[/tex]square inches.

3. [tex]\( \text{Number of flash cards} = \frac{144}{12} = 12 \).[/tex]

 Therefore, Juan can cut out 12 flash cards from the piece of cardboard."
