The number of adult tickets sold more than the children's tickets are 65.

It is given in the question that the charge of an adult ticket and a children's ticket is $8 and $6 respectively.

It is also given that, on a certain day the number of tickets sold are 255 at a total cost of $1,850.

We have to find the number by which children's ticket were sold more than adult tickets.

Let the number of children tickets sold on that particular day be x.

Let the number of adult tickets sold on that particular day be y.

Hence, according to the question,

x + y = 255  ...(1)

Also,

6*x + 8*y = 1850

Dividing 2 from both sides, we get

3x + 4y = 925  ...(2)

Multiplying (1) by 3, we get

3x + 3y = 765  ...(3)

(2) - (3)

(3x - 3x) + (4y - 3y) = 925 - 765

0 + y = 160

y = 160

Hence, the number of adult tickets sold are 160.

We know that,

x + y = 255

Hence,

x + 160 = 255

x = 255 - 160

x = 95

Hence, the number of children's tickets sold are 95.

The number of adult tickets sold more than the children's ticket are =

160 - 95 = 65 tickets.

Explanation:

SAS means Side-Angle-Side. So, two triangles are congruent if they have 2 sides that are congruent and the angle in the middle is also congruent.

In this case, we have 2 sides congruent: AB with DE and AC with DF.

So, the triangles are congruent if the angles A and D are also congruent.

Therefore, we can write the following equation:

So, solving for x, we get:

Therefore, the value of x that prove that the triangles are congruent is x = 10

The velocity vector is v = (30cos(5t)ur + 7ue) and the acceleration vector is a = -150sin(5t)ur.

Find velocity and acceleration vectors?

To find the velocity and acceleration vectors in terms of ur and ue, given the position vector r = 6sin(5t)ur + 7tue, we need to differentiate the position vector with respect to time.

1. Velocity vector:

v = dr/dt

Differentiating the position vector r = 6sin(5t)ur + 7tue with respect to time:

v = d/dt(6sin(5t)ur + 7tue)

 = (30cos(5t)ur + 7ue)

Therefore, the velocity vector is v = (30cos(5t)ur + 7ue).

2. Acceleration vector:

a = dv/dt

Differentiating the velocity vector v = (30cos(5t)ur + 7ue) with respect to time:

a = d/dt(30cos(5t)ur + 7ue)

  = (-150sin(5t)ur + 0ue + 0ur + 0ue)

  = -150sin(5t)ur

Therefore, the acceleration vector is a = -150sin(5t)ur.

Thus, the velocity vector in terms of ur and ue is v = (30cos(5t)ur + 7ue), and the acceleration vector in terms of ur is a = -150sin(5t)ur.

the wavelength of the electron is approximately 122 nm To find the wavelength of an electron, we can use the de Broglie wavelength formula:

wavelength (λ) = h / (m * v)

where:
- h is Planck's constant (6.63 x 10^-34 Js)
- m is the mass of the electron (9.11 x 10^-28 g, which needs to be converted to kg)
- v is the speed of the electron (5.97 mm/s, which needs to be converted to m/s)

Step 1: Convert the mass of the electron to kg:
9.11 x 10^-28 g * (1 kg / 1000 g) = 9.11 x 10^-31 kg

Step 2: Convert the speed of the electron to m/s:
5.97 mm/s * (1 m / 1000 mm) = 5.97 x 10^-3 m/s

Step 3: Plug the values into the de Broglie wavelength formula:
λ = (6.63 x 10^-34 Js) / (9.11 x 10^-31 kg * 5.97 x 10^-3 m/s)

Step 4: Calculate the wavelength:
λ = (6.63 x 10^-34 Js) / (5.44 x 10^-33 kg m/s) ≈ 1.22 x 10^-10 m

Step 5: Convert the wavelength to nm:
1.22 x 10^-10 m * (1 x 10^9 nm / 1 m) ≈ 122 nm

So, the wavelength is approximately 122 nm.

The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.

To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.

However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.

Therefore, the dog can run at approximately 3.125 mi/hr.

Step-by-step explanation:

Therefore, the total distance Gabe will paddle is 2x + 400 meters. The exact value of x depends on the width of the river, which is not provided in the given information.

To find the total distance Gabe will paddle, we need to consider the distance he will travel from Q to P, then from P to R, and finally from R back to Q.

First, let's consider the distance from Q to P. Since Gabe will paddle in a diagonal line across the river, this distance can be calculated using the Pythagorean theorem.

The length of the bridge (PR) is given as 400 meters, which is the hypotenuse of a right triangle. The width of the river can be considered as the perpendicular side, and the distance Gabe will paddle from Q to P is the other side. Let's call this distance x.

Using the Pythagorean theorem, we have:

x^2 + (width of the river)^2 = PR^2

Since the width of the river is not given, we'll represent it as w. Therefore:

x^2 + w^2 = 400^2

Next, let's consider the distance from P to R. Gabe will paddle along a route beside the bridge, which means he will travel the length of the bridge (PR) again. So, the distance from P to R is also 400 meters.

Finally, Gabe will paddle back from R to Q along the shore. Since he will follow the shoreline, the distance he will paddle is equal to the distance from Q to P, which is x.

To find the total distance, we add up the distances:

Total distance = QP + PR + RQ

= x + 400 + x

= 2x + 400

Yes, this is true. The R-squared value indicates how much of the variability of the data can be explained by the model. A higher R-squared value indicates that more of the variability of the data can be explained by the model, thus making the predictions more accurate.

To understand the concept better, let's consider an example. Suppose you have a model that predicts the price of a house based on its location, size, and other factors. Model A has an R-squared value of 0.7, while Model B has an R-squared value of 0.9. This means that Model B can explain more of the variability of the data than Model A, making it the more accurate predictor of the house price.

Additionally, the higher R-squared value of the model can also be an indication of the model's ability to generalize. If the model has a high R-squared value, it is likely that it can be applied to new data and still provide an accurate prediction. On the other hand, if the model has a low R-squared value, it may be difficult to apply it to new data and obtain accurate predictions.

The base of both hemisphere and cylinder will be the same circle with the same radius.

Also, we have,

Height of the tank = 16.5 m

Base diameter of the cylinder = 4.7 m

Radius of the base of the cylinder = 4.7 / 2 = 2.35 m

Radius of the hemisphere = 2.35 m

Height of the cylinder = Total height of the tank - Height or radius of the hemisphere

Total capacity of the tank = Volume of hemisphere + Volume of cylinder

The inverse of (x-A)^c = B, where A = 2x + 1, is x = -(B^(1/c) + 1).

To find the inverse of the expression in (x - A)^c = B, where A = 2x + 1, we can use the following steps:

First, solve for x in terms of A

x = (A - 1) / 2

Substitute the expression for A into the original equation

(x - (2x + 1))^c = B

Simplify

(-x - 1)^c = B

Take the c-th root of both sides

-x - 1 = B^(1/c)
