The cost of advance ticket is $35 and same-day ticket is $25.

What is meaning of cost?

The sum paid, levied, or equal amount for something: price. The average price of a college degree has significantly increased. the cost or expense (as in labor or sacrifice) incurred to accomplish a goal.

Given that, there are two types of tickets. One is advance ticket and other is same-day.

Assume that the cost of advance ticket be x and the cost of same-day be y.

The combine cost of advance ticket and same-day ticket is $60.

Therefore,

x + y = 60

y = 60 - x .....(i)

The cost of 25 advance ticket and 35 same-day ticket is 25x + 35y

According to the question,

25x + 35y = 1750 .....(ii)

Substitute y = 60 - x in equation (i)

25x + 35(60 - x) = 1750

25x + 2100 -35x = 1750

-10x = 1750 - 2100

-10x = -350

Divide both sides by -10:

x = 35

Putting x = 70 in equation (i):

y = 60 - 35

y = 25

The given argument is invalid. It says that if one person has more gray hair in their beard than another person, then they have a higher percentage of gray hair in their beard.

The argument is invalid because it is possible for one person to have a higher percentage of gray hair in their beard but a lower number of gray hairs in total.One possible counterexample by model is:Suppose Plato has 200 hairs in his beard and 50 of them are gray. So, 1/4 of his hairs are gray. Now, let's suppose Aristotle has 400 hairs in his beard, and 300 of them are gray. So, 3/4 of his hairs are gray. Even though Plato has fewer gray hairs than Aristotle, his percentage of gray hairs is more significant (1/4) than Aristotle's (3/4).

Therefore, the given argument is invalid since Aristotle's beard contains more gray hairs in quantity, but Plato has a higher percentage of gray hair in his beard.

Answer:

2 x 10^-2

Step-by-step explanation:

0.02 equals to 2/100

therefore 0.02= 2/102 (remember this is negative)

= 2x10^-2 (therefore -2)

The solution to the number 0.02 in scientific notation is 2 * 10⁻²

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

Number = 0.02

Multiply the number by 1

So, we have

Number = 0.02 * 1

Express 1 as 100/100

So, we have the following representation

Number = 0.02 * 100/100

Next, we have

Number = 2 * 1/100

Express 1/100 as 10⁻²

So, we have

Number = 2 * 10⁻²

Hence, the solution is 2 * 10⁻²

Change management is a significant challenge for many organizations during enterprise system implementation due to various factors such as resistance to change, organizational culture, lack of employee engagement, and inadequate communication and training.

During enterprise system implementation, organizations typically undergo significant changes in processes, roles, and technologies. This can lead to resistance from employees who may be accustomed to existing ways of working. Resistance to change can hinder the adoption and utilization of the new system, affecting its success.

Organizational culture also plays a role. If the organization has a rigid or hierarchical culture that is resistant to change or lacks a culture of innovation and learning, it becomes difficult to implement and integrate the new system effectively.

Lack of employee engagement and involvement in the implementation process can further impede change. Employees need to understand the reasons behind the change, how it will benefit them and the organization, and be provided opportunities for input and feedback.

Inadequate communication and training can be a major obstacle. Employees must be informed about the changes, their roles and responsibilities, and be provided with sufficient training to effectively use the new system. Insufficient communication and training can lead to confusion, frustration, and resistance.

Overall, change management is crucial during enterprise system implementation to address these challenges and ensure a smooth transition, user acceptance, and successful adoption of the new system.

Using the Laplace transform to solve the initial value problem y' + 4y = 0 with y(0) = 2 yields the equation Y(s) = 2/s - 2/s * e^(-4s).

Taking the Laplace transform of both sides of the differential equation and using the initial condition y(0) = 2, we get:

sY(s) - y(0) + 4Y(s) = 0

Simplifying, we get:

Y(s) = 2/s - 4Y(s)/s

Solving for Y(s), we get:

Y(s) = 2/s - 1/(s+4)

Using partial fraction decomposition, we can express Y(s) as:

Y(s) = 2/s - 2/(s+4)

Taking the inverse Laplace transform, we get:

y(t) = 2 - 2e^(-4t)

Therefore, the solution to the initial value problem is y(t) = 2 - 2e^(-4t).

Answer:

∠BCE is 115°

Step-by-step explanation:

The given parameters are;

The shape Tanya cut from the striped piece = Isosceles triangles

The measure of the vertex angle of the isosceles triangle = 50°

The segment \(\overline {BC}\) is parallel to the base \(\overline {FG}\)

Therefore, we have;

∠GAF + ∠AGF + ∠AFG = 180°; Sum of the interior angles of a triangle

∴ ∠AGF + ∠AFG =  180° - ∠GAF =  180° - 50° = 130°

∠AGF = ∠AFG;  Base angles of an isosceles triangle

∴ ∠AGF + ∠AFG = ∠AGF + ∠AGF = 2 × ∠AGF = 130°

∠AGF = 130°/2 = 65°

∠AGF = 65°

∠AGF ≅ ∠ACB, corresponding angles of two parallel lines, \(\overline {BC}\) and \(\overline {FG}\) cut by a transversal \(\overline {AG}\)

∠AGF = ∠ACB = 65°, definition of congruency

∠ACB + ∠BCE = 180° Sum of angles on a (straight) line

∠BCE = 180° - ∠ACB =  180° - 65° = 115°

∠BCE = 115°

Answer:

The 3rd one

Step-by-step explanation:

Let find angle z

Using law of sines

\( \frac{xy}{ \sin(z) } = \frac{xz}{ \sin(y) } \)

Plug in the numbers

\( \frac{43}{ \sin(x) } = \frac{40}{ \sin(68) } \)

Flip both equations

\( \frac{ \sin(x) }{43} = \frac{ \sin(68) }{40} \)

where z=85.4 or 94.6

Using the triangle interior sun theorem,

if z=85.4 let add up all so The first 2 are rules out angles to make sure they add up to 180.

\(if \: z = 85.4\)

\(85.4 + 68 + x = 180\)

\(x = 153.4\)

\(x = 26.6\)

The fourth one doesnt have 26.6 as a angle so it cant be that

Let try if z=94.6

\(68 + 94.6 + x = 180\)

\(162.6 + x = 180\)

\(x = 17.4\)

The third one has that.

Also we reuse law of sines YZ=12.9 so it is the third one.

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6

9a = 6

a = 6/9

a = 2/3

That is the slope.

The given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

To show continuity, we need to verify that the partial derivatives of ψ and φ with respect to x and y are equal. Let's calculate these partial derivatives:

∂ψ/∂x = 2y

∂ψ/∂y = 2x

∂φ/∂x = 2x

∂φ/∂y = -2y

From the above calculations, we can see that the partial derivatives of ψ and φ with respect to x and y are equal. Therefore, the condition for continuity, which requires the equality of partial derivatives, is satisfied.

To show irrotational flow, we need to verify that the curl of the velocity vector is zero. The velocity vector can be obtained from the stream function ψ and velocity potential φ as follows:

V = ∇φ x ∇ψ

Taking the curl of V:

∇ x V = ∇ x (∇φ x ∇ψ)

Using vector calculus identities and simplifying the expression, we find:

∇ x V = 0

Since the curl of the velocity vector is zero, the condition for irrotational flow is satisfied.

Therefore, based on the calculations and verifications, we can conclude that the given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

Given information: Mass of dolphin, m = 1800 N; Height of jump, h = 2.10 m.

The gravitational potential energy of the dolphin can be calculated as follows: Gravitational potential energy = mgh where, m is the mass of the dolphin, g is the acceleration due to gravity, and h is the height of the jump.

Given that the dolphin jumps from the water, its initial potential energy is zero. Hence, the total energy of the dolphin is equal to the potential energy at the highest point. At this point, the kinetic energy of the dolphin is also zero. Therefore, the energy conservation equation can be written as follows: mg h = (1/2)mv²where, v is the velocity of the dolphin just before it jumps out of the water.  

Solving for v, we get v = sqrt(2gh)where sqrt denotes the square root, g is the acceleration due to gravity, and h is the height of the jump. Substituting the given values, we get v = sqrt(2 x 9.8 x 2.10)v = 6.22 m/s Therefore, the dolphin must be moving at a speed of 6.22 m/s as it leaves the water in order to jump to a height of 2.10 m.
