The total pay change for each issue of Math is Fun sold by Carlos is $110. If he doesn't sell copies of Math is Fun, Carlos's gross wages are $2500 for him.

Given that:

x represents the number of copies of Math is Fun he sells. Suppose that x and y are related by the equation 2500 + 110x = y.

Equation: The equation is the values of two expressions that are equal.

Here,

For equation,

y = 2500 + 110x

The change in Carlos's total pay for each copy of Math is Fun he sells,

Differentiate the equation,

dy/dx = 110

The total pay for each copy of Math is Fun he sells is $110.

Carlos's total pay if he doesn't sell any copies of Math is Fun,

x = 0

y = 2500

Carlos's total pay if he doesn't sell any copies of Math is Fun is $2500.

Thus, the change in Carlos's total pay for each copy of Math is Fun he sells is $110. Carlos's total pay if he doesn't sell any copies of Math is Fun is  $2500.

Answer:

the answer is that there is 8 percent that they all will spend an hour on the internet.

Step-by-step explanation:

If the length of HJ is 7 unit then the length of EI is 14 unit.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

We are given a circle with center H.

Therefore, the radius of the circle is found as; HJ

Then the Diameter is the line from one point in the circle to the other point through the center of the circle.

Diameter of the circle = EI

Since we know that One of the theorems of a circle states that the angles in the same segments or on the same chord are equal.

Then the name of the chord is FG.

If the length of HJ is 7 unit then the length of EI is;

EI = 2 HJ

EI = 14 unit.

What are angles in parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.

We can conclude three factors determining parallel lines ,

Given data ,

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.

Each pair of alternate angles around the transversal are equal to each other.

The pairs of angles formed on the same side of the transversal that are either both obtuse or both acute and are called corresponding angles and are equal in size.

Each pair of corresponding angles on the same side of the intersecting transversal are equal to each other.

Co-interior angles on the same side of an intersecting transversal add to 180°

Hence , the angles are

Initial number of pairs of shoes is 20.

To achieve 50 pairs Mindy needs 30 more pairs.

Each week 2 pairs added but 1 removed. It makes total of 1 pairs addition.

After 28 weeks Mindy will have 20 + 28 = 48 pairs of shoes.

The next week he will purchase 2 more pairs and get 50 pairs in total.

The number of weeks it will take for her closet to have 50 pairs of shoes would be = 30 weeks.

A purchase price is the amount of money that was use to obtain a valuable.

The number of shoes owned by Mindy = 20 pairs

The number of shoes Mindy purchases per week = 2 pairs

The number of shoes Mindy destroys = 1 pair.

Therefore, in a week Mindy has an additional 1 pair of shoe.

The number of pairs she needs extra = 50-20 = 30

Since 1 pair of shoe = 1 week, she will require 30 weeks to purchase additional 30 pairs making it up to 50 pairs of shoes she owns.

Step-by-step explanation:

Given equation,

→ -8(1 + 4p) + 7p = -25 - 8p

Let's solve for the value of p,

→ -8(1 + 4p) + 7p = -25 - 8p

→ -8 - 32p + 7p = -25 - 8p

→ -32p + 7p + 8p = -25 + 8

→ -17p = -17

→ p = (-17)/(-17)

→ [ p = 1 ]

  B by a factor of about 5.208

Step-by-step explanation:

Given two right square pyramids (A and B) with perimeters 396 m and 496 m, and corresponding heights of 72 m and 239 m, you want to which has the greater volume and by what factor.

The volume of a right square pyramid is proportional to its height and to the square of its perimeter.

Pyramid B has both a longer perimeter and a greater height, so Pyramid B has the greater volume.

The constant of proportionality between the dimensions and the volume is the same for both pyramids, so the ratio of their volumes is ...

  Vb/Va = ((Pb)²Hb)/((Pa)²Ha) = (496²·239)/(396²·72) ≈ 5.208

Pyramid B has about 5.2 times the volume of Pyramid A.

Additional comment

The volume of a right square pyramid is given by ...

  V = 1/3s²h . . . . . where s is the side length and h is the height

  V = 1/3(P/4)²h = (1/48)P²h . . . . where P is the perimeter of the base

What is the slope of a line?

A line's slope, also known as its gradient, is defined as the value of a line's steepness or direction in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.

If P(a, b) and Q(c, d) are two given points on a coordinate plane, then the slope of line PQ can be computed using the formula

                        [tex]Slope(m) = \frac{d-b}{c-a}[/tex]

The slope of two perpendicular lines:

If two perpendicular lines are given then the product of their slopes will be equal to -1.

The given points are S(2,-9), 7(6, -6), U(9,-7), and V (6, y).

The slope of line ST   [tex]=\frac{-6-(-9)}{6-2}[/tex]

                                    [tex]= \frac{-6+9}{4}\\ = \frac{3}{4}[/tex]----------------(I)

Now, finding the slope of line UV,

The slope of line UV [tex]=\frac{y-(-7)}{6-9}[/tex]

                                  [tex]=\frac{y+7}{-3}[/tex]  ---------------(II)

Now, by using the property of slopes of two perpendicular lines, we can write

    Slope of line ST × Slope of line UV = -1

                                [tex]\frac{3}{4} *\frac{y+7}{-3}=-1 \\y+7=4\\y=4-7\\y=-3[/tex]

Answer: [tex]x=-3z+4, y=-2z+1, z=z[/tex]

Step-by-step explanation:

We have the system:

[tex]x-2y-z=2\\\\-x+3y+3z=-1\\\\-x+4y+5z=0[/tex]

Adding the first and second equations yields [tex]y+2z=1[/tex].

Adding the first and third equations yields [tex]2y+4z=2[/tex].

We know that there are infinitely many solutions, so [tex]y=1-2z[/tex].

Substituting this result back into the first equation,

[tex]x-2(1-2z)-z=2\\\\x-2+4z-z=2\\\\x+3z-2=2\\\\x=-3z+4[/tex]

The solution in term of z variable is; x = 4 - 3z

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have the linear system:

x - 2y - z = 2

-x + 3y + 3z = -1

-x + 4y + 5z = 0

Adding the first and second equations;

y + 2z = 1

Now Adding the first and third equations yield;

2y + 4z = 2

We know that there are infinitely many solutions, so;.

y = 1-2z

Then Substituting this result back into the first equation;

x - 2y - z = 2

x - 2( 1-2z) - z = 2

x - 2 + 4z - z = 2

x -4 + 3z = 0

x = 4 - 3z

The solution in term of z variable is; x = 4 - 3z
