Answer:

$132

Step-by-step explanation:

40% off means it is actually 60% of the regular price.

Thus, you will multiply the original (220) by .6 (this means 60 percent)

and you will get 220*.6=132

Answer:

132

Step-by-step explanation:

First, find 40% of 220, which is 88 (220 * 0.4). Since everything was marked down, 40% was taken off the original price. So, 220 - 88 = 132

There are seven lines of symmetry in a heptagon. In a heptagon, the sides and angles are equal. Each vertex and the center of a regular heptagon are where the line of symmetry crosses.

What is Reflectional Symmetry ?

Any symmetry with regard to a reflection is referred to as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected. There is a line/axis of symmetry in 2D and a plane of symmetry in 3D. When a form or pattern is mirrored in a line of symmetry or a mirror line, this is known as reflective symmetry. The reflected form will have the same size, distance from the mirror line, and other characteristics as the original shape. When a figure can be split into two equal halves that match, it has line symmetry or reflection symmetry.

If a figure can be reflected over a line and retain its original appearance, it possesses reflection symmetry. If a figure can be altered while maintaining its appearance, it possesses symmetry.

Step-by-step explanation:

The question seem incomplete;

The full question is

Which expression is equivalent to 4√6/3√2

Given

4√6/3√2

Required

Find equivalent

\(4\sqrt6/3\sqrt2\)

Rewrite Expression

\(\frac{4\sqrt6}{3\sqrt2}\)

Expand the above expression

\(\frac{4\ *\ \sqrt6}{3\ * \ \sqrt2}\)

Further split the fraction

\(\frac{4}{3}\ *\ \frac{\sqrt6}{\sqrt2}\)

Using rule of surds;

\(\frac{\sqrt a}{\sqrt b} = \sqrt{\frac{a}{b}}\)

So, the above expression becomes

\(\frac{4}{3}\ *\ \sqrt{\frac{6}{2}}\)

\(\frac{4}{3}\ *\ {\sqrt3}\)

\(\frac{4}{3}{\sqrt3}\)

At this stage, the expression cannot be further simplified;

Hence, 4√6/3√2  = \(\frac{4}{3}{\sqrt3}\)

We need to solve the given equation

\(\frac{x+3}{x+2} =3+\frac{1}{x}\)

To solve any equation we take LCD.

LCD of the given equation is x(x+2)

Multiply LCD with each term to remove the denominator

\(\frac{x+3}{x+2}\cdot x(x+2) =3\cdot x(x+2)+\frac{1}{x}\cdot x(x+2)\\x(x+3)=3x(x+2)+x+2\\x^2+3x=3x^2+6x+x+2\\\)

Answer: To find the number of cars that should be produced to incur minimum cost, we need to find the minimum value of the cost function C(x). Since C(x) is a quadratic function, it will have a minimum value, which is either a relative minimum or an absolute minimum. To find the number of cars that should be produced to incur the minimum cost, we will find the derivative of C(x) and set it equal to zero.

To find the derivative of C(x), we can use the power rule, which states that the derivative of x^n is n*x^(n-1).

The derivative of C(x) = 21000 - 90x + 0.1x^2 is

C'(x) = -90 + 0.2x

To find the minimum cost, we set C'(x) equal to zero and solve for x:

-90 + 0.2x = 0

0.2x = 90

x = 450

So, producing 450 cars will incur the minimum cost.

To verify that this is indeed a minimum, we can find the second derivative of C(x) which is 0.2, since the second derivative is positive, we can confirm that x = 450 is a relative minimum.

Alternatively, we can substitute x = 450 into the cost function and find the minimum value, which is C(450) = 21000 - 90(450) + 0.1(450)^2, which is less than any other value of C(x) for x≠450.

Therefore, to incur the minimum cost, 450 cars should be produced.

A simple difference is also called a marginal means difference. Option B

In experimental design and statistical analysis, a simple difference refers to the comparison of means between two groups or conditions. It represents the difference in average scores or values between the groups being compared. It is often used to assess the impact of an independent variable on a dependent variable by examining the variation in means between different levels of the independent variable.

The term "marginal means difference" emphasizes that the comparison is based on the average or marginal means of the groups being compared. It helps to distinguish it from other types of differences, such as interaction effects or main effects, which involve more complex comparisons or analyses in factorial designs.

Overall, a simple difference or marginal means difference is a straightforward way to evaluate the effect of an independent variable on a dependent variable by comparing the average values between different groups or conditions.

  1 1
  -1 1
  -1 1

2. Calculate the transpose of the matrix by interchanging rows with columns:
  1 -1 -1
  1 1 1

3. Multiply the matrix by its transpose:
  1 -1 -1    1
  1 1 1      1
  -1 1 1     -1

4. Calculate the eigenvalues and eigenvectors of the resulting matrix. This step involves finding the values λ that satisfy the equation A * v = λ * v, where A is the matrix.

5. Normalize the eigenvectors obtained in step 4 to obtain orthonormal eigenvectors.

6. The singular values are the square roots of the eigenvalues.

7. Create the matrix U by taking the orthonormal eigenvectors obtained in step 5 as columns.

8. Create the matrix Σ by arranging the singular values obtained in step 6 in a diagonal matrix.

9. Create the matrix V by taking the normalized eigenvectors obtained in step 5 as columns.

10. Finally, write the answer in the form of SVD: A = U * Σ * \(V^T\), where U, Σ, and \(V^T\) represent the matrices from steps 7, 8, and 9 respectively.

To find the singular value decomposition (SVD) of a matrix, we need to perform several steps. These include finding the eigenvalues and eigenvectors of the matrix, normalizing the eigenvectors, calculating the singular values, and creating the matrices U, Σ, and V. The SVD provides a way to factorize a matrix into three separate matrices and has many practical applications.

The percentage of B5 produced from coconut oil is 0.045 X% of the imported diesel fuel. The percentage of E10 produced from molasses and cassava is 0.1143 Y% of the imported petrol.

To calculate the volume of B5 (a biodiesel blend of 5% biodiesel and 95% petroleum diesel) that can be produced from the coconut oil produced in Fiji, we need to know the total volume of coconut oil produced and the conversion efficiency of the trans-esterification process.

Let's assume that the volume of coconut oil produced in Fiji is X million litres, and the conversion efficiency is 90%. Therefore, the volume of biodiesel (CME) that can be produced from coconut oil is 0.9X million liters. Since B5 is a blend of 5% biodiesel, the volume of B5 that can be produced is 0.05 × 0.9X = 0.045X million liters.

To calculate the total volume of E10 (a gasoline blend of 10% ethanol and 90% petrol) that can be produced from the molasses and cassava, we need to know the total volume of molasses and cassava produced and the conversion efficiency of ethanol production.

Let's assume that the total volume of molasses and cassava produced is Y million liters, and the conversion efficiency is 80%. Therefore, the volume of ethanol that can be produced is 0.8Y million liters. Since E10 is a blend of 10% ethanol, the total volume of E10 that can be produced is 0.1 × 0.8Y = 0.08Y million liters.

The percentage of B5 produced from coconut oil is (0.045X / 100) × 100% = 0.045 X% of the imported diesel fuel.

The percentage of E10 produced from molasses and cassava is (0.08Y / 70) × 100% = 0.1143 Y% of the imported petrol.
