Answer:

"x" children tickets are 70, "y" adult tickets 50 and "z" senior citizen tickets 25

Step-by-step explanation:

With the information of the statement we can pose the following equations:

we have to "x" children tickets, "y" adult tickets and "z" senior citizen tickets.

20.5*x + 29.75*y + 15.25*z = 2914.25

we also have to:

z = 2*y

plus that:

x = z + 20, replacing, we have left:

x = 2*y + 20

now, we replace each other in the main equation:

20.5*( 2*y + 20) + 29.75*y + 15.25*(2*y) = 2914.25

41*y + 410 + 29.75*y + 30.5*y = 2914.25

101.25*y = 2504.25

y = 2504.25/101.25

y = 24.73

z= 2*24.73 = 49.46

x = 2*24.73 + 20

x = 69.46

"x" children tickets are 70, "y" adult tickets 50 and "z" senior citizen tickets 25

Answer:

Children tickets = 69.4667

Adult tickets = 24.7333

Senior tickets = 49.4667

(The decimal does not make sense as we cannot have a fractional amount of tickets, but with the information given, this is the correct answer)

Step-by-step explanation:

Let's call the amount of children C, the amount of adults A and the amount of seniors S. Then, we can write the following system of equations:

C*20.5 + A*29.75 + S*15.25 = 2914.25 (eq1)

S = 2*A (eq2)

C = S + 20 (eq3)

Using eq2 in eq3, we have:

C = 2*A + 20 (eq4)

Using eq2 and eq4 in eq1, we have:

(2*A + 20)*20.5 + A*29.75 + 2*A*15.25 = 2914.25

41*A + 410 + 29.75*A + 30.5*A= 2914.25

101.25*A = 2504.25

A = 2504.25 / 101.25 = 24.7333

Now using eq2, we have:

S = 2*A = 49.4667

And using eq4, we have:

C = 2*A + 20 = 69.4667

(The decimal does not make sense as we cannot have a fractional amount of tickets, but with the information given, this is the correct answer)

Cone and cylinder are two of the objects shown below could we slice diagonal to their bases/faces to create an ellipse cross-section.

The asymmetrical oval shape is drawn by a spot advancing along a plane so that the sum of its distance from foci is kept the same, known as an ellipse.

A circle is created by cutting at a right angle to the axis. An ellipse is created by cutting at an angle that is more than the angle created by the side of the cone but less than the right angle to the axis.

Every plane that a circular cylinder cross is at a straight angle to its axis. The cylinder is intersected in a curve that resembles an ellipse by a plane that is neither parallel to nor at right angles to the axis.

Hence, cone and cylinder are two of the objects shown below could we slice diagonal to their bases/faces to create an ellipse cross-section.

The requried mean absolute deviation is given as 1.625.

The statistic is the study of mathematics which deal with relations between comprehensive data.

Here,
Average of the given number = 25 + 23 + 23 + 24 + 25 + 26 + 27 +27 / 8
                                              = 197 / 8
Average = 24.625

mean absolute deviation (MAD) = 1/n ∑[xi - average]

mean absolute deviation (MAD) = [|22 - 24.625| + |23 - 24.625|+|23 - 24.625|+|24 - 24.625|+|25 - 24.625|+|26 - 24.625|+|27 - 24.625|+|27 - 24.625|]/8

mean absolute deviation (MAD)  = [2.625+1.625+1.625+0.625+0.375+1.375+2.375+2.375]/8

mean absolute deviation (MAD) = 13 / 8 = 1.625

Thus, the requried mean absolute deviation is given as 1.625.

The value of x is 36°.

Given Information:

  - The angle at the top of the star is labeled [tex]\(72^\circ\).[/tex]

  - There is an angle labeled BFC on line AFC.

Angle Sum Property:

  - The sum of the angles formed on a line is [tex]\(180^\circ\).[/tex]

Equation Setup:

  - The angles BFC and [tex]\(72^\circ\)[/tex] are part of the line AFC.

  - So, [tex]\(BFC + 72^\circ = 180^\circ\).[/tex]

Isolate the Unknown Angle:

  - Subtract [tex]\(72^\circ\)[/tex] from both sides of the equation:

[tex]\[BFC = 180^\circ - 72^\circ\].[/tex]

Expression for BFC:

  - Simplify the expression to find the measure of BFC:

[tex]\[BFC = 108^\circ\].[/tex]

6. Variable x:

  - The angle BFC is expressed in terms of x: BFC = 3x.

Equation Setup for x:

  - Set 3x equal to the known value of BFC:

[tex]\[3x = 108^\circ\].[/tex]

Solve for x:

  - Divide both sides by 3:

[tex]\[x = \frac{108^\circ}{3} = 36^\circ\].[/tex]

Therefore, the value of [tex]\(x\) is \(36^\circ\).[/tex]

Answer:

i think D or B is the answer

Step-by-step explanation:

Answer:

B. 1 x-intercept

Step-by-step explanation:

We can use the discriminant expression, b²- 4ac, to answer this question.

In the equation y = 3x² + 6x + 3 we know that,

3 = a-value

6 = b-value

3 = c-value

Using this information, we can plug these numbers into the discriminant expression to find the discriminant.

6² - 4(3)(3) = 0

Because the value is equal to 0, we know there is 1 real solution and therefore there is 1 x-intercept.

Answer:

The answer to the questions asked is:

a) The maximum possible income for the museum is $4,840 per day.

b) The increase you must make to obtain the maximum income is $8 per ticket.

c) The income of the museum without increasing the fee is $4200.

Step-by-step explanation:

To solve all the questions asked, we must take into account the provided equation:

The first question asks for the maximum income, that is, the maximum amount of money that can be obtained by making increases in the rate, despite the loss of people, so you must replace the X in the equation with values ​​until instead of increase decrease:

As you can see, when the increase is $9, the income falls, so the maximum income is $4,840, while it can be seen that it occurs with an increase of $8, which answers the second question.

For the third question, that is, the income of the museum without increasing the fee, you must remember that the variable X is the increase in the fee, therefore, if you want to obtain the income without an increase, it must be given a value of zero to the variable inside the equation, with which we obtain:

Answer:

Step-by-step explanation:

Surface area is the area of all the sides

The area of the rectangular base is W x L =  30 x 30 = 900

Then to find the area of the triangles its [tex]\frac{1}{2}[/tex]bh

A = [tex]\frac{1}{2}[/tex] 30 x 20

A = [tex]\frac{1}{2}[/tex] 600

A = 300

Since there are 4 triangle faces on a pyramid we times 300 x 4 = 1200 is the area of all the triangles

Then we add the area's

1200 + 900 = 2100

To calculate the length of CD, additional information about the geometric figure is necessary. Meanwhile, for operations like addition or subtraction, results should be rounded to the same number of decimal places as the number with the least decimal places.

The student's question seems to refer to the relationship between angles in a geometric figure and determining the length of a side, specifically the length of CD, within that figure. However, to provide a correct and precise length of CD, more information from the geometric figure or additional conditions are required, such as side lengths or other angle measurements. As the question stands, it lacks sufficient data to calculate the length of CD.

Regarding rounding, in general when you are performing mathematical operations like addition or subtraction, the result should be rounded to the same number of decimal places as the number with the least number of decimal places. For example, if you were to add 5.123 to 2.5, the result should be rounded to one decimal place, since 2.5 has only one decimal place. The correct sum would be 7.6.

Answer:

5.4 laps

Step-by-step explanation:

One lap = 5/6 miles

= 0.833miles (approximately)

If 0.833 miles = 1 lap

4.5 miles = ?

4.5/0.833 = 5.4 laps

Final answer:

To find the number of laps the track team ran, divide the total distance by the length of each lap. In this case, the team ran approximately 5.4 laps.

Explanation:

To find the number of laps the track team ran, we need to divide the total distance they ran by the length of each lap. The total distance they ran is 4 1/2 miles, which can be written as 9/2 miles. Each lap is 5/6 miles long.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. So, to find the number of laps, we can multiply 9/2 by the reciprocal of 5/6: (9/2) x (6/5) = 54/10 = 5.4.

Therefore, the track team ran approximately 5.4 laps.

Step-by-step explanation:

We have been given a graph of a board. We are asked to find the probability that dart will hit in region II.

The probability that dart will hit the region II will area of region II over area of board.

Let us find area of region II. We can see that one side of region II is 35 and other is 20.

[tex]\text{Area of Region II}=35\times 20[/tex]

[tex]\text{Area of Region II}=700[/tex]

Length of board would be [tex]35+15=50[/tex]

Width of board would be [tex]20+8=28[/tex]

[tex]\text{Area of board}=50\times 28[/tex]

[tex]\text{Area of board}=1400[/tex]

[tex]\text{Probability that dart will land in region II}=\frac{700}{1400}[/tex]

[tex]\text{Probability that dart will land in region II}=\frac{1}{2}[/tex]

[tex]\text{Probability that dart will land in region II}=0.5[/tex]

Therefore, the probability that dart will land in region II is 0.5.

Answer:

D

Step-by-step explanation:

These are transformations. One thing to remember is that only a sign change (like a negative sign on the new function) will change the direction in which the parabola opens.

Here, going from f(x) to 1/2 * f(x) has no sign change, so the parabola will open in the same direction as before. Eliminate A and C.

Vertical transformations are those that are done to the entire function, as opposed to horizontal transformations which are done only on the x. Here, since we're multiplying 1/2 to f(x), we have a vertical transformation.

There are different transformations. The one here would be a vertical shrink by a factor of 1/2. Vertically shrinking a function is basically the same as compressing it, which would make it wider.

The answer is thus D.

Answer:

Last one:

The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).

Step-by-step explanation:

g(x) = ½f(x)

g(x) is obtained by a vertical stretch of f(x) by factor ½ (compression)

g(x) would look like f(x), would just be wider
