Answer:

The mark up is $21.16 and the final selling price is $44.14

Step-by-step explanation:

To find the mark up price, you simply multiply the cost by the mark up percentage. This will give you the mark up.

$23 * 92% = $21.16

Now to find the total selling price, we add the cost and the mark up together.

$23 + $21.16 = $44.16

Final answer:

The amount of markup on the Algebra 1 book is $21.16, calculated by multiplying the wholesale price of $23 by the markup percentage of 92%. The selling price of the book is $44.16, the sum of the wholesale price and the markup.

Explanation:

To calculate the amount of the markup for the Algebra 1 books, we will apply a percentage increase to the wholesale price. The wholesale price of each book is $23, and the markup percentage is 92%. To find the markup amount, we multiply the wholesale price by the markup percentage:

Markup = wholesale price × Markup percentage

Markup = $23 × 0.92
Markup = $21.16

Now, to calculate the selling price, we add the markup to the wholesale price:

Selling Price = Wholesale Price + Markup
Selling Price = $23 + $21.16
Selling Price = $44.16

Therefore, the amount of the markup is $21.16, and the selling price of the book is $44.16.

The answer to this question is 0.9

We know that

sequre of 9 is equal to 81  as [tex]9^2 = 81[/tex]

Then sequre of 0.9 will be

[tex]0.9^2 = 0.81[/tex]

So,

b = [tex]\sqrt{ 0.81}[/tex]

b = [tex]\sqrt{ 0.9^2}[/tex]

Exponent and square root cancel out each other

So, the answer is 0.9.

-5x -4(x-6) = -3

distribute

-5x -4x+24 = -3

combine like terms

-9x +24 = -3

subtract 24 from each side

-9x = -27

divide by -9

x = 3

Answer:

x=3

Step-by-step explanation:

−5x−4(x−6)=−3

To solve for x:

for this we have to make the equation in such a way that the variable x lies on the left side and constant terms on the right side.

First distribute -4 over x and -6

We get -4x+24.

Substitute in the equation.

-5x-4x+24 =-3

Subtract 24 from both the sides

-5x-4x = -3-24

Or =9x = -27

Answer:

60 hummingbirds can be fed by a 12 ounce feeder.

Step-by-step explanation:

In order to solve this problem, we can make a ratio table. For every 16 ounce feeder, 80 hummingbirds can be fed. However, we want to calculate how many hummingbirds can be fed by a 12 ounce feeder. We can get a common denominator for our ratio to solve this. 16:80 divided by 4:4 is 4:20. Since 4 is a factor of 12, we can multiply 4 by 3 to get 12. However, what we do to one section we do to the other. 20 x 3 is 60. 60 hummingbirds can be fed by a 12 ounce feeder.

Your answer would be 4379 members because at the very beginning you had started off with 4372 members, however as the months go by changes happen. On october, it changed by -10, meaning that 10 students left the school meaning 4372-10=4362 members remaining. Then there's november with -8, so you subtract 8 from your new total 4362-8=4354. Then december comes, and this time it's a positive number, so you have to add 23 to 4354, giving you a new total of 4377. Then there's january, and its back to a negative number so you subtract 12 from 4377, 4377-12=4365. Then february comes and it's a change of a positive number, so you add 3 to the 4365, giving you 4368. And then finally by march, it's another positive number so you add 11 to your total, giving you 4379 students which are now at school. So basically if it's a negative change, subtract from the total, and if it is a positive, add to it. And you have to continue with the total that you got from the previous change that you did. Hope this was helpful

basically you start with 4372 the table shows what happens during the school so after September you go to October which is -10 so you end up with 4362 then, November which is -8 so you get 4354 then in December you have +23 which makes 4377 then in January you have -12 which makes 4365 then in Feburary you have +3 which makes 4368 then in march you have +11 so 4379 so

Then you add the money you invested to your interest so your answer would be  ' C ',

I think I'm not that great with math but I really hope I helped you .

Answer:

D. $2630

Step-by-step explanation:

Given,

The principal amount, P = $ 2000,

Annual rate of interest, r = 4.5 % ,

Thus, the interest for 7 years,

[tex]I=\frac{P\times r\times 7}{100}[/tex]

[tex]=\frac{2000\times 4.5\times 7}{100}[/tex]

[tex]=\frac{63000}{100}[/tex]

[tex]=630[/tex]

Hence, the amount after 7 years or at the beginning of the 8th year is,

[tex]A=P+I=2000+630=\$ 2630[/tex]

Option 'D' is correct.

To solve the expression 8.246 minus 5 hundredths, we subtract 0.05 from 8.246, aligning the decimal places, which gives us the final answer of 8.196, accurately rounded to the thousandths place.

To solve 8.246 - 5 hundredths, we need to understand what five hundredths mean. Five hundredths is the same as 0.05. So, the problem now looks like 8.246 - 0.05.

When we subtract these two values, we need to line up the decimal places properly:

Subtracting, we get:

It's important to note that when subtracting values, you must consider the position of the farthest right significant figure. In this case, the least precise number (original number) had its farthest right significant figure in the thousandths place, so our final answer is also rounded to the thousandths place.

lily get 3 /(4+3)

she get 3/7

Final answer:

Lily receives 3/7 of the total money when it is shared in a 4:3 ratio with Annie.

Explanation:

If Annie and Lily share some money in the ratio of 4:3, we can use this ratio to determine what fraction of the money Lily gets. The total parts of the ratio are 4 (for Annie) plus 3 (for Lily), which equals 7 parts in total.

Lily's share is 3 parts of the total 7 parts. So, Lily receives 3/7 of the total money. This fraction represents Lily's portion when the money is divided according to the given ratio.

Answer:

  Change in number of bushels after 6 days = 46.4 bushels.

Explanation:

 A farmer has 140 bushels of wheat to sell at his roadside stand.

  He sells an average of [tex]15\frac{3}{5}[/tex] bushels each day = [tex]\frac{15*5+3}{5} =\frac{78}{5}[/tex]bushels

  Total number of bushels sold after 6 days = 6* [tex]\frac{78}{5}[/tex] = 93.6 bushels.

  Change in number of bushels after 6 days = 140 - 93.6 = 46.4 bushels.

Answer: He has about 46 bushels left (46.4)

Step-by-step explanation:

Hi, to answer this question we have to multiply the average sell of bushels per day (15 3/5) by the number of days stated (6):

Finally we have to subtract the number obtained to the number of bushels that the farmer had at the beginning.

He has about 46 bushels left (46.4)

10x + 2y > 20

Solution

Step 1: First we have to rewrite the given equation y in terms of x.

Subtract 10 x from both sides, we get

10x - 10x + 2y > -10x + 20

2y > -10x + 20

Divide both sides by 2, we get

y > -5x + 10

Step 2: Now we have to find the coordinates by plugging in the values of for x = -1, 0, 1

and  find the corresponding values for y.

Plug in x = -1,

y = -5(-1) + 10 = 5 + 10 = 15.

The coordinates are (-1, 15)

Plug in x = 0, we get

y = -5(0) +10 = 10

The coordinates are (0, 10)

Plug in x = 1, we get

y = -5(1) + 10 = -5 +10 = 5

The coordinates are (1, 5)

Step 3: Now plot the points on a grid and draw the draw the dotted line because it is greater than. Since it is grater than we have to shaded the region above the line.

Converting a power into an equivalent multiplication expression involves rewriting the power's base and exponent using multiplication. The exponent signifies how many times to multiply the base by itself.

Converting a power into an equivalent multiplication expression with two factors involves rewriting the power's base and exponent. Consider, for example, a power like 6^3. This expression can be rewritten as multiplication with two factors in different ways, such as 6 x 6 x 6 or 36 x 6. The exponent value tells us how many times to multiply the base by itself. Remember that this is true for all types of powers, including whole numbers, negative numbers, and fractions, which means your multiplication expression factors may differ.

ANSWER

The zeros are [tex]x=-5,x=0,x=5[/tex]

EXPLANATION

Given;

[tex]f(x)=x^4-25x^2[/tex].

We can rewrite the function as

[tex]f(x)=x^2(x^2-25)[/tex]

[tex]\Rightarrow f(x)=x^2(x^2-5^2)[/tex]

[tex]\Rightarrow f(x)=x^2(x-5)(x+5)[/tex]

The zeros are found by equating the function to zero.

[tex]\Rightarrow x^2(x-5)(x+5)=0[/tex]

[tex]\Rightarrow (x-5)=0[/tex]

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is [tex]x=5[/tex]

Or

[tex]\Rightarrow (x+5)=0[/tex]

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is [tex]x=-5[/tex]

Or

[tex]\Rightarrow x^2=0[/tex]

This last root has a multiplicity of 2.

That is

[tex]x=0[/tex] repeats two times.

Since the multiplicity is even, the graph touches the x-axis at the point [tex]x=0[/tex].

See graph.

The zeros of the function ƒ(x) = x4 -25x2 are -5, 0, and 5. Each of these zeros has a multiplicity of 1. The graph crosses the x-axis at each of these zeros, indicating odd multiplicities.

The polynomial function given is ƒ(x) = x4 -25x2. In order to find the zeros, you set the function equal to zero and solve for x: 0 = x4 -25x2. This can be rewritten as x2(x2 - 25) = 0. From this, it's clear that x = 0 is a zero of the function. The other zeros can be found by setting x2 - 25 = 0, resulting in x2 = 25, and therefore, x = ±5. So, the zeros are -5, 0, and 5. Each of these zeros has a multiplicity of 1, because the factorization of f(x) doesn't include any squared terms. The graph crosses the x-axis at each of these points, which is characteristic of odd multiplicities.

Final answer:

To find the value of x, we can use the given equations and the Angle Sum Property of a Triangle. By substituting the known values into the equation (9x-10), we can solve for x.

Explanation:

To find the value of x, we can use the facts given in the question. We know that m<mkl = 83 and m<jkl = 127. We also know that m<jkm = (9x-10). From these facts, we can form two equations:

1. m<mkl = 83

2. m<jkl = 127

Using these equations, we can determine the value of x.

Let's solve the first equation:

1. m<mkl = 83

Since m<mkl = 83 and m<jkl = 127, we can substitute these values into equation (9x-10) according to the Angle Sum Property of a Triangle:

2. 83 + 127 + (9x-10) = 180

Simplifying the equation, we get:

3. 210 + 9x - 10 = 180

Combining like terms, we have:

4. 9x + 200 = 180

Subtracting 200 from both sides, we get:

5. 9x = -20

Dividing both sides by 9, we find:

6. x = -20/9

Therefore, the value of x is -20/9.
