Answer:

¼ per month or 2 books in 2½ months

Mariam read 4 books in 5 months, resulting in a rate of reading of 4/5 books per month.

Use the concept of fraction defined as:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.

Given that,

Mariam read 4 books

She read the books in 5 months

We need to find her rate of reading, in books per month

To find the rate of reading,

Divide the number of books read by the number of months it took to read them.

In this case, Mariam read 4 books in 5 months.

So, the rate of reading would be 4 books divided by 5 months.

Simplifying this fraction, we have 4/5,

Hence, Mariam's rate of reading is 4/5 books per month.

The distance between the two points in the simplest radical form is √61

From the question, we are to determine the distance between the two marked points

The marked points are (-8, 6) and (-3, 0)

The distance, d, between two points can be calculated by using the formula,

d = √((x₂ - x₁)² + (y₂ - y₁)²)

x₁ = -8

x₂ = -3

y₁ = 6

y₂ = 0

Thus,

The distance, d, between the points is

d = √((-3 - -8)² + (0 - 6)²)

d = √((-3 + 8)² + ( -6)²)

d = √((5)² + 36)

d = √(25 + 36)

d = √61

Hence, the distance between the two points in the simplest radical form is √61

I’m not sure but I think it’s 8 in.; 50.27 in.

By using athematic operations, we get the cost of the company A's 3000 copies is greater than that of the other two.

What are arithmetic operations?

The arithmetic operator is used to carry out mathematical operations on the specified operands, including addition, subtraction, multiplication, division, and modulus. A few examples of arithmetic operators are as follows: 5 + 3 = 8, 5 - 3 = 2, 2 * 4 = 8, etc.

Given that:

Copier rentals from company A cost $90 per month + 6 cents every copy and

Copier rentals from company A cost $180 per month + 3 cents every copy

Let the number of copies be x

Total rents for a month of Company A [tex]= 90+0.06x[/tex]

Total copiers rents for a month of  Company B [tex]= 180+0.03x[/tex]

Total rents for a month of Company A = Total copiers rents for a month of  Company B

⇒[tex]90+0.06x= 180+0.03x[/tex]

Taking unknown value left side

[tex]0.06x-0.03x=180-90\\0.03x=90\\x=\frac{90}{0.03} \\x=3000[/tex]

The attached below is the graph and the three points to solve the equation is (0,1) , (1,5/2) and (-1,-1/2)

According to the question the equation that we have been given is

              -3x + 2y = 2

We need to graph the linear equation. For this we will first put different values of x in the above equation and then find the values of y which will be the coordinates of the graph.

First put x = 0

                  -3(0) + 2y = 2

                         2y = 2

                          y = 1

hence the first coordinate is (0,1)

Similarly put,     x = 1

                       -3(1) + 2y = 2

                           2y = 5

                             y = 5/2

            when x= -1 then y = -1/2

Thus the three point or coordinates are (0,1) , (1,5/2) and (-1,-1/2) and below is the graph.

The number of miles for same rental costs are 300 miles.

Let the number of miles be x.

Firstly calculating the cost of Company a -

Total cost = One day cost + Number of miles × Cost per mile

Total cost = 110 + 0.70x

Calculating the cost of Company b -

Total cost = One day cost + Number of miles × Cost per mile

Total cost = 80 + 0.80x

Now, for the same rental cost, we will equate the two expressions. This will calculate the value of x.

110 + 0.70x = 80 + 0.80x

Rearranging the expression -

110 - 80 = 0.80x - 0.70x

Performing subtraction

30 = 0.10x

Shifting the values on other side of equation

x = 30/0.10

Performing division

x = 300

Hence, the rental cost for both companies will be same for 300 miles.

The magnitude of the resultant velocity of the soccer ball is 10 m/s .

Let the horizontal component of velocity be [tex]V_{x}[/tex] and the vertical component  of velocity be [tex]V_{y}[/tex].

The magnitude of the resultant velocity will be represented by V.

So, we can write

The horizontal component of velocity = [tex]V_{x}[/tex] = 8 m/s

The vertical component  of velocity = [tex]V_{y}[/tex] = 6 m/s

The relation between horizontal component, vertical component and resultant velocity is,

[tex]V^{2} = V_{x} ^{2} + V_{y} ^{2}[/tex]

On substituting value of horizontal component and vertical component, we get

[tex]V^{2}[/tex] = [tex](8)^{2} + (6)^{2}[/tex]

[tex]V^{2}[/tex] = 64 + 36

[tex]V^{2}[/tex] = 100

V = [tex]\sqrt{100}[/tex]

V = 10 m/s

The magnitude of the resultant velocity of the soccer ball is 10 m/s .

The rate of change of the area of circle with respect to radius is: 8π.

The rate at which one quantity changes in relation to another quantity is known as the rate of change of a function.

When we rotate a  Parallelogram PQRS of 90 degrees clockwise about the origin, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure.

P(x₁, y₁) ⇒ P'(y₁ , -x₁ )

Q(x₂, y₂) ⇒ Q'(y₂ , -x₂ )

R(x₃, y₃) ⇒ R'(y₃ , -x₃ )

S(x₄, y₄) ⇒ S'(y₄ , -x₄ )

The Greek word "parallelogrammon," which means "bounded by parallel lines," is the source of the English word "parallelogram." Thus, a quadrilateral with parallel lines as its borders is referred to as a parallelogram. The opposing sides of this form are parallel and equal. Each of the three primary varieties of parallelograms—square, rectangle, and rhombus—has distinct characteristics.

A unique variety of quadrilateral made up of parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but it must have opposing sides that are parallel for it to be a parallelogram. If the opposing sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both sets of opposite sides are parallel and equal is referred to as a parallelogram.
