what percent of 54 is 23? explained

Answers

Answer: 42.59

Step-by-step explanation:

Step 1: First, write the problem as an equation: P% = X/Y

Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54

Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100

Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54

Step 5: Solve for P

P/100 = 23/54

P = (23/54) * 100 = 42.59

Therefore, 23 is 42.59 percent of 54

Which of the following equations has nosolution? B= -B+ 2 B + 2= b + 2 B+ b = 2 b + 2 = b-2

Answers

the equation B= -B+2B+2 has no solution

given equation B= -B+2B+2=b+ 2B +b= 2b+2= b-2

taking B= -B+2B+2

           2B=2B+2

             2=0        hence no solution

taking -B+2B+2=b+2B+b

           -B   =  2b-2

            B=  2(1- b)       is the solution of equation

 taking  b+2B+b=2b+2

a list of measurements in increasing order is 4, 5, 6, 8, 10, and x . if the median of these measurements is ​six sevenths​ times their arithmetic mean, what is the value of x ?

Answers

In a list of measurements in increasing order: 4, 5, 6, 8, 10, and x, the value of x is 16.

To get the value of x, we will use algebraic expressions to demonstrate the given relationships.

If the median of these measurements is ​six sevenths​ times their arithmetic mean, then:

median = 6/7 x mean

Median (Md), is a single value at the middle of the data values arranged in increasing or decreasing order. On the other hand, arithmetic mean (μ) is the sum of the data values divided by its total number.

For the list of measurements in increasing order is 4, 5, 6, 8, 10, and x,

The median is between 6 and 8.

Md = 6+8/2

Md = 7

Evaluating the first equation using Md = 7:

median = 6/7 x mean

7 = 6/7 x mean

mean = 49/6

By definition,

mean = (4 + 5 + 6 + 8 + 10 + x)/6

Equating both equations for the mean:

49/6 = (4 + 5 + 6 + 8 + 10 + x)/6

49 = 33 + x

x = 16

Hence, the value of x is 16.

What is an average value?

Average value can be calculated by finding the  sum of a set of numbers  then count the total number, then divide the sum with the  number of the counted values.

To calculate the average weight of the sled team members, then we know that there are  11 dogs and the musher, which implies that there are total number of 12 animals.

Then we can find the total number of the dogs as (11*70) =770 dogs, then we can add to the musher which makes the total number of (770+160)=930

One half|is a component|is an element} to part quantitative relation and also the alternative is an element to whole quantitative relation.

Given,

Men : Women = 4 : 7

Total number of employees =  143

Let us take a multiplying factor of x

This implies, Number of men = 4x , Number of women = 7x

Using the given data, we get 4x + 7x = 143

                                                  11x = 143

                                                   x = 143 / 11

                                                   x = 13

Number of men = 4x = 4 (13) = 52

A theater is showing a ballet performance. Tickets are available on three levels in the performance hall. Lower level tickets cost $35, mezzanine tickets cost $25, and upper balcony tickets cost $15. For a certain performance the theater sold 5 times as many lower level tickets as upper balcony tickets. The theater sold $37,500 in tickets for that performance. The money made from mezzanine tickets alone was 4 times the money made from upper balcony tickets. How many lower level tickets were sold for that performance?

Answers

Based on the calculation done below, the number of lower level tickets sold is 750.

How do we calculate the number of units sold from a word problem?

Let:

L = number of lower-level tickets sold = 5U

M = number of mezzanine tickets sold

U = number of upper balcony tickets sold

We therefore have:

35L + 25M + 15U = 37,500 ...................... (1)

25M = 4 * 15U = 60U

Substituting L = 5U and 25M = 60U into equation (1) and solve for U, we have:

35(5U) + 60U + 15U = 37,500

175U + 60U + 15U = 37,500

250U = 37,500

U = 37,500 / 250

U = 150

Susbstituting U = 150 into L = 5U, we have:

L = 5 * 150

Answers

For the given quadratic function we have that:

Domain: Set of all real values.Range: y ≤ 3.

What is the domain and range of the quadratic function?

For a function h(x), we define the domain as the set of the inputs (values of x) and the range is the set of the outputs (values of y).

Generally, for all quadratic functions, the domain is the set of all real numbers, so we already know the domain.

Now let's look at the range.

The given function is:

h(x) = -12*(x - 4)^2 + 3

Remember that if a quadratic function has a vertex (h, k), then the vertex form is:

f(x) = A*(x - h)^2 + k

So the vertex here is (4, 3)

And we also can see that the leading coefficient of the quadratic function is negative. This means that the function opens downwards, so the vertex is the maximum.

Then the range is the set of all real values smaller than or equal to 3, then the range is:

R: y ≤ 3.

Concluding:

Domain: Set of all real values.Range: y ≤ 3.
