Answer:

The artist's earnings for the CD will be $168000.

Step-by-step explanation:

The total sales amount is $2500000

The artist receives a royalty payment of 7%. So, the amount of royalty, the artist receives will be:  [tex](\$2500000\times 7\%)= (\$2500000\times 0.07)=\$175000[/tex]

The agent gets 4% of what the recording artist gets. So, the amount of money the agent gets will be:  [tex](\$175000\times 4\%)=(\$175000\times 0.04)=\$7000[/tex]

So, the artist’s earnings for the CD will be:  [tex](\$175000-\$7000)= \$168000[/tex]

Answer:

[tex]x=28cos(z)\\y=28sin(z)[/tex]

Step-by-step explanation:

We have been given a right triangle, which the following dimensions:

Hypotenuse = 28

Angle = z

Adjacent = x

Opposite = y

Upon using trigonometric ratio for cosine, we can write:

[tex]cos(z)=\frac{\text{Adjacent}}{\text{Hypotenuse}} =\frac{x}{28}\\ x=28cos(z)[/tex]

Similarly, upon using trigonometric ratio for sine, we get write:

[tex]sin(z)=\frac{\text{Opposite}}{\text{Hypotenuse}} =\frac{y}{28}\\ y=28sin(z)[/tex]

The point-slope formula:

[tex]y-y_1=m(x-x_1)[/tex]

We have a slope m = 2 and point (-8, 2)

Substitute:

[tex]y-2=2(x-(-8))\\\\y-2=2(x+8)[/tex]

[tex]\bf 3x+(2x+5)+(2x+10)+(2x-15)=360 \\\\\\\\3x+2x+2x+2x+10+5-15=360\implies 9x+0=360\\\\\\\\x=\cfrac{360}{9}\implies x=40\\[/tex]

Answer:

The volunteers donated  [tex](15040-470n)[/tex] milliliters of blood.

Step-by-step explanation:

Total number of volunteers was 32 and the number of volunteers couldn't donate blood was [tex]n[/tex].

So, the number of remaining volunteers who donated blood will be: [tex](32-n)[/tex]

Each of these volunteers donated 470 milliliters blood.

So, the total amount of blood donated [tex]= 470(32-n) = (15040-470n)[/tex] milliliters.

Answer:

Answer: The answer to this problem would be (32-n)*470!

Step-by-step explanation:

Since there were 32 volunteers the beginning and some of them couldn't donate you would subtract (the variable you would use is 'n'). As you may know, each means that you multiply so if each volunteer is giving 470 mm of blood each you would multiply that by how many volunteers are remaining which is unknown.

Your final answer would be: (32-n)*470

Answer:

You can conclude that the lines are perpendicular, and will cross at exactly one point.

Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.

The slope of a line illustrates the direction of the line

The two lines are perpendicular lines

From the question, we understand that:

As a general rule,

A vertical line and a horizontal line will meet at a right-angle

Hence, the conclusion about the two lines is that, the two lines are perpendicular lines

Answer: The answer is (C). [tex]y\geq 0.[/tex]

Step-by-step explanation:  We are given a graph in the figure and we are to identify the range of the graphed function from the given options.

We can see in the figure that the values of x are greater than or equal to 0 and the corresponding values of y are also greater then or equal to 0. Since we are talking about the range of the function, so we will consider the y-values.

Thus, the range of the function will be [tex]y\geq 0.[/tex]

To decide which one is the better deal, you need to compare them on price per ear. So, the the first vendor is $2.56/8ears= $0.32/ear

the second vendor: $4.32/12 = $0.36/ear

The first vendor with the bag of 8 ears is the better deal!

Answer:

The better deal is first vendor bag.

Step-by-step explanation:

Given : A corn vendor at a farmers market was selling a bag of 8 ears of corn for $2.56. Another vendor was selling a bag of 12 for $4.32.

To find : Which bag is the better deal?

Solution :

To compare which is better we find the unit rate of both vendor rate.

The selling price of first vendor of 8 ears of corn for $2.56.

The selling price of 1 bag is [tex]\frac{2.56}{8}[/tex]

The selling price of 1 bag is $0.32.

The selling price of second vendor of 12 ears of corn for $4.32.

The selling price of 1 bag is [tex]\frac{4.32}{12}[/tex]

The selling price of 1 bag is $0.36.

The unit price of first vendor bag is lower than second vendor.

So, the better deal is first vendor bag.

To rewrite one equation like x = 4 - y into ax + by = c form, we adjusted it to x + y = 4. Then, we combined it with the unchanged equation y = 2x + 3 by substituting 'y' in the first equation with 'y' from the second, leading to 3x + 3 = 4, a one-variable equation.

To rewrite one of the two equations into the form ax + by = c, it's essential to start by having an equation that resembles y = a + bx (which is the same as y = mx + b, the conventional form for a linear equation) and the other in any format initially. Let's assume these equations as the existing ones: y = 2x + 3 and x = 4 - y.

Step 1: Transform the equation x = 4 - y into the form ax + by = c.

Firstly, shift y to the left side of equation by adding 'y' to both sides:

x + y = 4,

That's it! We now have the equation in the required ax + by = c format, where a = 1, b = 1 and c = 4.

Step 2: Add this new equation to the unchanged equation.

x + y = 4 (New one after rearranging)

y = 2x + 3 (Unchanged equation)

By substituting y from the second equation into the first, it will result in an equation in one variable:

x + (2x + 3) = 4,

After simplifying the equation, we get

3x + 3 = 4,

That is the result as an equation in one variable.

= [tex]\frac{9}{4 * 1}[/tex]

Answer in fraction form: = [tex]\frac{9}{4}[/tex]

Answer in decimal form: = 2.25

Final answer:

To divide 3/4 by 1/3, multiply 3/4 by the reciprocal of 1/3, which is 3/1, giving you 9/4. This fraction is already in its lowest terms.

Explanation:

To divide fractions, such as dividing 3/4 by 1/3, you need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/3 is 3/1. So, you should alter the division problem to a multiplication problem.

Here is the step-by-step process:

Write down the problem in multiplication form: (3/4) * (3/1).

Multiply the numerators together: 3 * 3 = 9.

Multiply the denominators together: 4 * 1 = 4.

You get the result of the multiplication as 9/4.

To reduce to the lowest terms, we see that 9/4 is already in its simplest form as both 9 and 4 are prime to each other.

Thus, when you divide 3/4 by 1/3, the answer in lowest terms is 9/4.

The equation of the line parallel to the line y = -7x + 2 will be -

y = - 7x - 3.

Given is the equation of line as y = -7x + 2.

        y = mx + c

The equation of line parallel to the given line will be of the form -

y = - 7x + c                                               {parallel lines have same slope}

For the point (- 5, 32), we can write -

32 = - 7 x - 5 + c

c = 32 - 35

c = - 3                                                       {y - intercept}

The equation of the line will be -

y = - 7x - 3

Therefore, the equation of the line parallel to the line y = - 7x + 2 will be -

y = - 7x - 3.
