Answer: Heater -Rs 2400; Fan- Rs 1600

Step-by-step explanation:

Given

Ajay bought a fan and a heater for Rs 4000

Suppose the price of fan is x and that of heater is 4000-x

Profit on the fan is \(0.25x\)

Loss on heater is \(0.05\times (4000-x)\)

Total profit is 7% i.e. \(0.07\times 4000\)

\(\therefore 0.07\times 4000=0.25x-0.05(4000-x)\\\Rightarrow 280=0.25x-200+0.05x\\\Rightarrow 480=0.3x\\\Rightarrow x=1600\)

Thus, the price of heater is \(4000-1600=Rs.\ 2400\)

Price of fan is \(Rs.\ 1600\)

Price of heater is \(Rs.\ 2400\)

The individual cost of fan and heater are;

Cost of fan = Rs. 1600

Cost of heater = Rs. 2400

Total Cost price of heater and fan = Rs 4000

Let cost of fan be x

Thus cost of heater = 4000 - x

Percentage Profit of sale of fan = 25% = 0.25

Loss percentage on heater = 5% = 0.05

Thus;

Profit on fan = 0.25x

Loss on heater = 0.05(4000 - x)

Total profit of all sales = 0.07 × 4000

Thus;

0.07 × 4000 = 0.25x - 0.05(4000 - x)

280 = 0.25x - 200 + 0.05x

480 = 0.3x

x = 480/0.3

x = Rs. 1600

Thus;

Cost of heater = 4000 - 1600

Cost of heater = Rs. 2400

The best estimate for the weight of a cantaloupe is 2 kilograms (B).

A decigram is 1/10th of a gram, which would be too small of weight for a cantaloupe. 2 grams (C) is also too small for a cantaloupe as it would only be the weight of a few small seeds. 2 milligrams (D) is an extremely small weight, only suitable for a single grain of salt or a tiny insect.

Therefore, 2 kilograms (B) is the most reasonable estimate for the weight of a cantaloupe as it falls within the typical range of cantaloupe weights.

The method "average" should accept two integer parameters. Here is a step-by-step explanation of how to write this method:

1. Start by defining the method called "average" and specifying that it accepts two integer parameters. The syntax may vary depending on the programming language you are using, but it could look something like this:

```java
public int average(int num1, int num2) {
  // method body
}
```

2. Inside the method body, calculate the average of the two integers by adding them together and then dividing the sum by 2. This can be done using basic arithmetic operations:

```java
public int average(int num1, int num2) {
  int sum = num1 + num2;
  int average = sum / 2;
  return average;
}
```

3. Finally, return the calculated average as the result of the method.

Now, let's consider an example to better understand how this method works. Suppose we call the "average" method with the integers 4 and 6 as arguments. The method will calculate the sum of 4 and 6, which is 10. Then, it will divide the sum by 2 to get the average, which is 5. Finally, it will return the average as the output.

So, calling the method like this:

```java
int result = average(4, 6);
```

will assign the value 5 to the variable "result".

This is a basic example of how to write a method called "average" that accepts two integer parameters. Remember that the implementation may vary depending on the programming language you are using, but the general idea remains the same: add the two integers together and divide the sum by 2 to calculate the average.

Answer:

The fridge takes up 36 2/3 cubic feet of space.

Step-by-step explanation:

To calculate the volume of the fridge, you need to multiply the width, height, and depth.

Width = 2 2/3 feet = (2*3 + 2) / 3 = 8/3 feet

Height = 5 1/2 feet = (5*2 + 1) / 2 = 11/2 feet

Depth = 2 1/2 feet = (2*2 + 1) / 2 = 5/2 feet

Volume = (Width) * (Height) * (Depth)

Volume = (8/3 feet) * (11/2 feet) * (5/2 feet)

Calculating the volume:

Volume = 8 * 11 * 5 / (3 * 2 * 2) cubic feet

Volume = 440 / 12 cubic feet

Volume = 36 2/3 cubic feet

An inequality that can be written in the form ax + by < c (where a and b are not both zero) is called a linear inequality in two variables.

An inequality that represents a line in a two-dimensional coordinate system is referred to as a linear inequality. The set of points that satisfies the inequality is a half-plane bounded by a line that may be dashed or solid.

In contrast to a linear equation, which represents a line, a linear inequality represents a half-plane. The points on one side of the line, rather than the points on the line, are solutions to the inequality.

The method of shading is used to graph a linear inequality in two variables. First, graph the boundary line, which is usually represented by a solid or dashed line, and then select a test point on one side of the line. Shaded regions of the half-plane containing the test point satisfy the inequality.

Spherical harmonics are an integral part of quantum mechanics. They describe the shape of the orbitals, which electrons occupy in atoms. Moreover, the spherical harmonics provide the angular distribution of a wave in spherical coordinates. In 3D, the spherical harmonics can be written as:

Ylm(θ, φ) = √(2l + 1)/(4π) * √[(l - m)!/(l + m)!] * Plm(cosθ) * e^(imφ)

Here, l and m are known as the angular quantum numbers. They define the shape and orientation of the orbital. Plm(cosθ) represents the associated Legendre polynomial, and e^(imφ) is the exponential function. The spherical harmonics have various forms, including:

Y1,1 = -Y1,-1 = 1/2 √(3/2π) sinθe^(iφ)

Y1,0 = 1/2 √(3/π)cosθ

Y2,2 = 1/4 √(15/2π)sin²θe^(2iφ)

Y2,1 = -Y2,-1 = 1/2 √(15/2π)sinθcosφ

Y2,0 = 1/4 √(5/π)(3cos²θ-1)

Y0,0 = 1/√(4π)

The spherical harmonics have various applications in physics, including quantum mechanics, electrodynamics, and acoustics. They play a crucial role in understanding the symmetry of various systems. Hence, the spherical harmonics are an essential mathematical tool in modern physics. Thus, this is how one can show another form for spherical harmonics.

The length of \(\overline{JO}\) is 48.

Step-by-step explanation:

A square is a quadrilateral whose four sides have the same length and four internal angles have the same measure. The sum of measures of internal angles in quadrilaterals equals 360°. Let \(m\,\angle BOJ = 4\cdot x -6\) and \(BO = 2\cdot x - 8\), the value of \(x\) is:

\(4\cdot (4\cdot x - 6) = 360^{\circ}\)

\(16\cdot x -24 = 360^{\circ}\)

\(16\cdot x = 384^{\circ}\)

\(x = 24\)

And the length of \(JO\) is:

\(JO = BO = 2\cdot x - 8\)

\(JO = 40\)

The length of \(\overline{JO}\) is 48.

Degree of Financial leverage (DFL) = (EBIT) / (EBT)

Earnings Before Interest and Taxes (EBIT) = $750,000

$1,000,000 x 4.5% = $1,000,000 x 4.5/100

= $45000

To find EBT ( Earnings Before Tax),

EBT = EBIT - 45000

       = 750000 - 45000

EBT = 705000

The length of the curve described by the function is approximately 21.14 units.

The length of the curve described by the function y = f (x) can be found using the formula below:$$\int_{a}^{b} \sqrt{1+\left[\frac{d y}{d x}\right]^{2}} d x$$

Where, a and b are the limits of the function.The function is y = 3x² + 4, which is a quadratic function.

Therefore, the derivative of y can be obtained as follows:$$\frac{d y}{d x} = 6x$$

Substitute the derivative of y into the formula to obtain:$$\int_{a}^{b} \sqrt{1+(6 x)^{2}} d x$$Integrating,

we have:$$\int_{a}^{b} \sqrt{1+36 x^{2}} d x$$Let u = 1 + 36x², then du/dx = 72x

which implies dx = 1/72 du/u^(1/2).

Hence, the integral is transformed to:

$$\frac{1}{72} \int_{1}^{37} u^{1 / 2} d u$$

Therefore, the integral is equal to:

$$\frac{1}{72}\left[\frac{2}{3} u^{3 / 2}\right]_{1}^{37}

In order to determine whether or not a rational function has a horizontal asymptote, one can compare the degrees of the numerator & denominator of the function.

To understand why, let's first define what a rational function is. A rational function is a function that can be expressed as a ratio of two polynomials. In other words, it is a function of the form f(x) = P(x) / Q(x), where P(x) & Q(x) are both polynomials

Let's now think about what occurs when x gets closer to infinity or negative infinity. The value of the function will approach 0 as x approaches infinity or negative infinity if the degree of the numerator is smaller than the degree of the denominator

The function has a horizontal asymptote at y = 0 if the degree of the numerator is smaller than the degree of the denominator. The function has a horizontal asymptote at y = the ratio of the leading coefficients & if the degrees are equal, & it does not if the degree of the numerator is larger than the degree of the denominator

The probability of event F given that event E has occurred is approximately 0.5850.

The conditional probability of an event F given that event E has occurred is the probability that both events E and F occur, divided by the probability that event E occurs. It is denoted as P(F|E).

In this problem, Here,  P(E) = 0.326, P(F) = 0.298, and P(E ∩ F) = 0.191. We want to calculate P(F|E).

Using the conditional probability formula, we have:

P(F|E) = P(E ∩ F) / P(E)

Substituting the given probabilities, we get:

P(F|E) = 0.191 / 0.326

Simplifying the expression, we get:

P(F|E) ≈ 0.5850

Therefore, the probability of event F given that event E has occurred is approximately 0.5850.

The probability that the customer likes neither hot nor iced coffee can be calculated by subtracting the probability of the customer liking hot coffee or iced coffee from 1. Let A be the event that the customer likes neither hot nor iced coffee. Then, P(A) = 1 - P(H) - P(I). If P(H) = 0.6 and P(I) = 0.4, then P(A) = 1 - 0.6 - 0.4 = 0. Therefore, the probability that the customer likes neither hot nor iced coffee is 0.
To find the probability of an event, we need to divide the number of favorable outcomes by the total number of possible outcomes. Here, the customer can either like hot coffee, iced coffee, or neither. Since the customer can only like one of the two options, we can use the complement rule to find the probability of the customer not liking either. We subtract the sum of probabilities of the customer liking hot and iced coffee from 1.

The Pythagorean Theorem is a fundamental concept that relates to the sides of a right-angled triangle, and it can also be used to understand the relationship between the areas of the squares constructed on the sides of the triangle.

The area of a square is given by the formula A = s², where s is the length of one of its sides. Therefore, the areas of the three squares are:

Area of the square with side a = a²

Area of the square with side b = b²

Area of the square with side c = c²

Now, let's compare the areas of the squares. We can start by subtracting the area of the square with side a from the area of the square with side c:

c² - a²

Using the Pythagorean Theorem, we know that c² = a² + b². Substituting this into the above expression, we get:

c² - a² = (a² + b²) - a² = b²

This tells us that the difference between the area of the square with side c and the area of the square with side a is equal to the area of the square with side b. In other words:

c² - a² = b²

This is known as the Pythagorean identity. It states that in any right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. We can also rearrange this identity to obtain the following:

c² = a² + b²

This is the Pythagorean Theorem that we are familiar with. Therefore, we can conclude that the relationship between the areas of the squares constructed on the sides of a right-angled triangle is given by the Pythagorean identity: the difference between the area of the square on the hypotenuse and the area of the square on the shorter side is equal to the area of the square on the other shorter side.
