The average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.

To solve the problem of determining the average cost of a movie ticket in Japan and Switzerland, we need to set up a system of equations based on the information given. If we let J represent the cost of a ticket in Japan and S represent the cost of a ticket in Switzerland, we can formulate the following equations from the scenario provided:

3J + 2S = $81.61 (Cost for three tickets in Japan and two in Switzerland)

3S + 2J = $77.44 (Cost for three tickets in Switzerland and two in Japan)

Now we solve the system of equations using substitution or elimination method. For simplicity, we'll use the elimination method:

Multiply the first equation by 3 and the second equation by 2 to make the coefficients of S the same:

9J + 6S = 3 x $81.61 = $244.83

6S + 4J = 2 x $77.44 = $154.88

Subtract the second new equation from the first to eliminate S:

9J + 6S - (6S + 4J) = $244.83 - $154.88

5J = $89.95

Divide by 5 to solve for J:

J = $89.95 / 5 = $17.99

Now substitute the value of J in either original equation to solve for S:

3(17.99) + 2S = $81.61

53.97 + 2S = $81.61

2S = $81.61 - 53.97

2S = $27.64

Divide by 2 to solve for S:

S = $27.64 / 2 = $13.82

Therefore, the average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.

Answer:

Step-by-step explanation:

For matrix subtraction, you subtract the corresponding cell of the second matrix from the first. So, looking at the first spot, you have 4 (from the first matrix) - 4 (from the second matrix) = 0 (the first number in the output matrix). Continuing that for the next spot, -4 - -3 = -4 + 3 = -1. Finally, -2 - 5 = -7. This means your answer is [0 -1 -7].

Step-by-step explanation:

thomas read faster than  brice!!! wheres the graph btw?

The correct statement of the given ones is that Thomas is reading at a faster rate than Brice.

        [y] = mx + c

Given are Brice and Thomas who are reading the same book. The graph

shows the number of pages that Brice read in a week and the equation

y = 21x + 33 shows the number of pages that Thomas read in a week.

The given equation for Thomas that shows the number of pages that Thomas read in a week is -

y = 21x + 33

The slope of the line is -

m = 21

Thomas is reading 21 pages per week.

For the graph of Brice, it passes through the points (0, 43) and (6, 163). So, we can find the slope as -

m = (163 - 43)/(6 - 0)

m = 120/6

m = 20

Brice is reading 20 pages per week.

Therefore, the correct statement of the given ones is that Thomas is reading at a faster rate than Brice.

Answer:

Square feet.

Step-by-step explanation:

Feet are an example of what are called linear units. They're used to measure one dimensional things like length, width, or height. Area is two-dimensional, it takes up (flat) space, so we need to measure it in units that do the same thing. The simplest two-dimensional shapes to measure area with turn out to be squares (since the area of a square with side length s is just s²), so we usually measure area in square units. Since our linear units here are feet, the corresponding square units will be square feet.

Answer:

I think the answer is square feet.

ANSWER

[tex] \cos( \alpha ) + \sin( \alpha ) [/tex]

EXPLANATION

The given expression is

[tex] \frac{ \cos(2 \alpha ) }{ \cos( \alpha ) - \sin( \alpha ) } [/tex]

Recall and use the double angle identity,

[tex] \cos(2 \alpha ) = { \cos}^{2} \alpha - { \sin}^{2} \alpha [/tex]

This implies that,

[tex]\frac{ \cos(2 \alpha ) }{ \cos( \alpha ) - \sin( \alpha ) } = \frac{ \ { \cos}^{2} \alpha - { \sin}^{2} \alpha }{ \cos( \alpha ) - \sin( \alpha ) } [/tex]

Recall again that: a²-b²=(a-b)(a+b)

We use difference of two squares to obtain,

[tex]\frac{ \cos(2 \alpha ) }{ \cos( \alpha ) - \sin( \alpha ) } = \frac{ (\ { \cos}\alpha - { \sin}\alpha )(\ { \cos}\alpha + { \sin}\alpha)}{ \cos( \alpha ) - \sin( \alpha ) } [/tex]

We cancel out the common factors to get,

[tex]\frac{ \cos(2 \alpha ) }{ \cos( \alpha ) - \sin( \alpha ) } = { \cos}\alpha + { \sin}\alpha[/tex]

The expression cos(2α)cosα−sinα is equivalent to the formula 2tanα / (1+tan^2α), reached by substituting cos(2α) with 1 - 2sin^2α and recognizing the resulting function as the derivative of the tangent function.

In addressing your question on expressions equivalent to cos(2α)cosα−sinα, we will employ some trigonometric identities. The expression cos(2α)cosα−sinα is equivalent to the expression 2tanα / (1+tan^2α).

The way to reach this answer is to first know the identity cos(2α) = 1 - 2sin^2α and plug this into the equation. The result will be 2sin^2α cosα + sinα. Then, you recognize this is the derivative of the tangent function, and find that it equals 2 tanα / (1 + tan^2α).

Answer:

4

Step-by-step explanation:

The numbers in order would be

2, 3, 4, 5, 7

The number in the middle is always the median

Therefore, 4 is the median

Final answer:

The median of the list 5, 7, 2, 4, 3 is 4, once the numbers are arranged in ascending order and we identify the middle value in the set.

Explanation:

To find the median of the list 5, 7, 2, 4, 3, we must first organize the numbers in either ascending or descending order. For this set, arranged in ascending order, we get 2, 3, 4, 5, 7. Since we have n = 5 numbers, the median will be the third value in the ordered set, which is the middle number. Therefore, the median of this data set is 4.

A. Car share I hope this helps

The most likely choice for someone needing a car for a few hours to pick someone up from the airport is a car share, due to its convenience and cost-effectiveness for short-term use.

A person who needs a car for just a few hours to pick up a friend from an airport would most likely choose car sharing. This option allows for the short-term use of a car, typically charged by the hour or mile, and is ideal for brief, one-time needs such as an airport pick-up. In contrast, car rental is more suitable for those who need a vehicle for a full day or longer. A car lease is a long-term arrangement, usually spanning several years, and therefore not practical for a few hours of use. Carpooling involves sharing a ride with others going in the same direction but does not provide the flexibility of going to the airport to pick someone up specifically.

When deciding on options like these, one must consider the economic choices and personal needs. Factors like fuel efficiency, car size, and whether all-wheel drive is necessary for local weather conditions should be taken into account for longer-term choices. However, for a few hours of need, car sharing emerges as the most convenient and economical option.

Answer:

(4,9)

Step-by-step explanation:

If f(x) is a function, the function f(x) + a is a function translated a units up vertically. Hence, all the y-coordinates of the coordinates of the points on the function will shift up by a.

For this problem, we need to find corresponding coordinate of (4,4) of f(x) + 5. This means that the y-coordinate of this coordinate will increase by 5 and x will stay the same.

Hence, corresponding point for f(x) + 5 for the point (4,4) would be (4,4+5) OR (4,9).

Step-by-step explanation:

[tex]1\ ft=12\ in\to1\ in=\dfrac{1}{12}\ ft\\\\\text{Therefore, if you want to change inches to feet,}\\\text{you must divide the number of inches by 12.}\\\\\text{Examples:}\\\\36\ in=\dfrac{36}{12}\ ft=3\ ft\\\\120\ in=\dfrac{120}{12}\ ft=10\ ft[/tex]

The graph opens upward and has a minimum value of –3

Which statement describes the graph of the function

From the question, we have the following parameters that can be used in our computation:

y - 2x² = -3

This can be expressed as

y = 2x² - 3

The above has a positive leading coefficient

This means that it opens up

And as such it has a minimum and no maximum

Using the above as a guide, we have the following:

The graph opens upward and has a minimum value of –3

The side lengths of a dilation of quadrilateral LMNP can be determined by multiplying the original side lengths by the dilation scale factor. For example, a scale factor of 2 would double the side lengths, resulting in a dilated quadrilateral with doubled dimensions.

The question asks about the side lengths of a dilation of quadrilateral LMNP with original sides measuring 16, 28, 12, and 32. In mathematics, a dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The scale factor of the dilation determines how much larger or smaller the dilated figure will be compared to the original.

For example, if a quadrilateral LMNP is dilated by a scale factor of 2, all side lengths would be twice as long as the original. Therefore, the dilated quadrilateral would have sides of 32 (16×2), 56 (28×2), 24 (12×2), and 64 (32×2). Conversely, if the dilation scale factor is 0.5, the sides would be half as long, resulting in lengths of 8, 14, 6, and 16 respectively.

To determine the side lengths of a dilated version of LMNP, simply multiply each of the original side lengths by the dilation scale factor. This property of similarity due to dilation applies to any polygon, maintaining the shape but altering the size proportionally in all dimensions.

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's find the area of the triangle:

Area = (Base * Height)/2

Area = (20 * 6)/2

Area of the flower bed = 60 m²

2. Now, let's calculate the number of bags of topsoil Betsy needs to cover her flower bed:

Number of bags = Area of the flower bed/Area covered by a bag of topsoil

Number of bags = 60/20

Number of bags = 3

The correct answer is B. 3 bags

There are 3 bags of topsoil Betsy needs to cover her flower bed option (B) is correct.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

As we know,

The area of the triangle = (1/2)base length×hieght

= (1/2)20×6

= 60 square m

One bag of topsoil covers 20 square meters.

Number of bags = 60/20 = 3 bags

Thus, there are 3 bags of topsoil Betsy needs to cover her flower bed option (B) is correct.
