Step-by-step explanation:

The Formula for finding C.P., when

S.P. = Rs. 500    and Loss% = 20%   is:

CP = ( SP * 100 ) / ( 100 – percentage loss )

Putting values in the formula we get,

CP = ( 500*100) / (100 - 20)

Ans = Rs 625.

https://brainly.com/question/21173801

The cost price is Rs. 625.

Cost price = 100 × selling price/100 - loss%

CP = 100 × 500/100-20

     = 100 × 500/80

     = 5000/8 = 625

Thus, the cost price is Rs.625.

For 6 ounces of powder, Jeff will use 7 cups of water, and to make 7 boxes of gelatin, Jeff will use 7/6 * 6 ounces = 7 ounces of powder and 7 cups of water.

What is the ratio?

A ratio is a relationship between two things when it is expressed in numbers or amounts.

To determine the amount of powder and water Jeff will use to make 7 boxes of gelatin, we need to determine the ratio of powder to water for each amount of gelatin.

From the table, we can see that for 3 ounces of powder, 9 cups of water are used, which means that for 1 ounce of powder, 3 cups of water are used.

Similarly, for 6 ounces of powder, 7 cups of water are used, which means that for 1 ounce of powder, 7/6 cups of water are used.

Since these two ratios are not the same, we cannot simply multiply both values by 7 to get the total amount of powder and water for 7 boxes of gelatin.

Instead, we will use the ratio that corresponds to the number of boxes of gelatin closest to 7, which in this case is 6 boxes of gelatin.

Hence, For 6 ounces of powder, Jeff will use 7 cups of water, and to make 7 boxes of gelatin, Jeff will use 7/6 * 6 ounces = 7 ounces of powder and 7 cups of water.

Step-by-step explanation:

The solutions of the system are:

(-3, -1), (-20, 15)

Given inequalities are y > 3/2x - 2 and y ≤ -3x - 4

The area of the solution is the shaded area

Let us check the points

(-2, -5) it lies on the red dashed line

Since the line is dashed, then the points lie on it do not belong to the solution, then

(-2, -5) is not a solution

(-2, 2) it lies on the red dashed line

Since the line is dashed, then the points lie on it do not belong to the solution, then

(-2, 2) is not a solution

(0, -4) it is out of the shaded area then

(0, -4) is not a solution

(-3, -1) it lies in the shaded area, then

(-3, -1) is a solution

(-1, 4) it is out the shaded area, then

(-1, 4) is not a solution

(-20, 15) is in the shaded area, then

(-20, 15) is a solution

Given:

A quadratic equation is

\(-6=x^2+4x-1\)

To find:

The standard form of the given equation and find the value of c.

Solution:

The standard form of a quadratic equation is

\(ax^2+bx+c=0\)               ...(i)

We have,

\(-6=x^2+4x-1\)

It can be rewritten as

\(0=x^2+4x-1+6\)

\(0=x^2+4x+5\)

\(x^2+4x+5=0\)            ...(ii)

On comparing (i) and (ii), we get

\(c=5\)

Therefore, the value of c is equal to 5 and the correct option is C.

Answer:

the answer is c

Answer:

x=10/7

Step-by-step explanation:

simplify both sides of the equation

2 * 2 + 6 = 7x

4 + 6 = 7x

combine like terms

(4 + 6) = 7x

10 = 7x

flip the equation

7x = 10

divide both sides by 7

7x/7 = 10/7

answer is 10/7

Zachary will need to earn a score of 23 on his sixth quiz to have a mean score of 22 for all six quizzes.

To find out what score Zachary needs to earn on his sixth quiz to have a mean score of 22,

We need to use the formula for the mean (or average) of a set of numbers:

Mean = (sum of all the scores) / (number of tests)

Zachary's mean score for the first five quizzes is 22.

Using the above as a guide, we have the following:

(20 + 25 + 22 + 18 + 24 + x) / 6 = 22

Evaluate the like terms

(109 + x) / 6 = 22

So, we have

109 + x = 132

Evaluate the like terms

x = 23

Hence, the score must be 23

Answer:

No

Step-by-step explanation:

substitute the x- coordinate of the point into each equation and if both have the value of the y- coordinate of the point then it is a solution.

y = 5(3) + 9 = 15 + 9 = 24 ≠ 9

y = 3 + 6 = 9

since the point does not satisfy both equations then it is not a solution of the system.

A quadratic equation is a polynomial equation of degree 2, which means the highest power of the variable is 2. It is generally written in the form: ax^2 + bx + c = 0. Option (d) x = -8, x = 8 is the correct answer.

The given equation is 15x^2 - 56 = 88 - 6x^2.

We need to find the values of x that are solutions to the given equation.

Solution: We are given an equation 15x² - 56 = 88 - 6x².

Rearrange the equation to form a quadratic equation in standard form as follows: 15x² + 6x² = 88 + 56  21x² = 144  

x² = 144/21 = 48/7

Therefore x = ±sqrt(48/7) = ±(4/7)*sqrt(21).

The values of x that are solutions to the given equation are x = -4/7 sqrt(21) and x = 4/7 sqrt(21).

The given equation is 15x² - 56 = 88 - 6x². Values of x are solutions to the equation below 15x² - 56 = 88 - 6x² are x = -2.62, 2.62 or x ≈ -2.62, 2.62.

Firstly, let's add 6x² to both sides of the equation as shown below.

15x² - 56 + 6x² = 88

15x² + 6x² - 56 = 88

Simplify as shown below.

21x² = 88 + 56

21x² = 144

Now let's divide both sides by 21 as shown below.

x² = 144/21

x² = 6.86

Now we need to solve for x.

To solve for x we need to take the square root of both sides.

Therefore, x = ±√(6.86).

Therefore, the values of x are solutions to the equation below are x = -2.62, 2.62 or x ≈ -2.62, 2.62.

The statement that best describes the Central Limit Theorem is (a) The distribution of means of random samples pulled from a population will be normally distributed if the sample size is large enough.

The Central Limit Theorem (CLT) states that if repeated random samples is taken from a population with a finite mean and standard deviation, then the distribution of the sample means will approach a normal distribution, even if the original population is not normally distributed.

The larger the sample size, the more closely the sample means will approximate a normal distribution.

which means that, for example, if we take multiple samples of size 100 from a population and calculate the average of each sample, the distribution of those sample means will be approximately normally distributed, regardless of the original shape of the population.

Answer:

Step-by-step explanation:

When there is a problem with Solver being able to find a solution, many times it is an indication of mistakes in the formulation of the problem. This means that the problem may not be correctly defined, or the constraints may not be properly specified.

However, it is also possible that the problem is a nonlinear programming problem, which can be more difficult for Solver to solve. In either case, it is important to carefully review the problem formulation and constraints to ensure that they are correct and accurately represent the problem at hand. It is also important to note that there may be some problems that cannot be solved using Solver or any other optimization tool, due to their inherent complexity or other factors.
