Answer: $2376

Step-by-step explanation:

First, get the area of the rectangle by using the formula L * W
9 * 12 = 108 feet squared

Now, that you have the area you can multiply that since each square yard is $22 so you do

108 * 22 = 2376

Which is $2376

Answer: Dilation, scale factor of 2.

Step-by-step explanation: The scale factor would be the number we multiply the 4 by 6 rectangle to get the 8 by 12 rectangle print.

Since we start with a rectangle with a length of 6 and a width of 4, and the measurements are changed to 8 and 12, we know the scale factor is 2. The scale factor is two because 4 • 2 is 8, and 6 • 2 is 12. Out of the transformations, (reflection, rotation, translation, dilation) the only one that includes a scale factor would be dilation. We also know it’s a dilation since the print is getting larger, and the pre image and image are not the same.

Answer:

1/3

Step-by-step explanation:

just took the quiz

Here is the completed table:

Feet 3  6  9  18 21

Yard  1  2   3  6   7

The mathematical operations that would be used to solve this question are multiplication and division. Multiplication is the process that is used to determine the product of two or more numbers. Division is the process of determining the quotient of two or more numbers.

The first step is to determine the unit of conversion of yards to feet and feet to yards.

Unit of conversion of yards to feet = 9 / 3 = 3

Unit of conversion of feet to yards = 3/9 = 1/3

This means that: 1 yard = 3 feet

1 feet = 1/3 yards

3 feet =  3/3 = 1 yard

6 feet = 6 / 3 = 2 yard

6 yard = 6 x 3 = 18 feet

7 yard = 7 x 3 = 21 feet

What is Angles?

An angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given,

c || d

<1 = <7

We have to prove a || b

∠1 = ∠5         corresponding angles of lines a and b

∠1 = ∠4          are alternate interior angles of lines a and b

∠5 = ∠7         corresponding angles of lines a and b

∠3 = ∠7         corresponding angles of lines a and b

Therefore, a || b by converse corresponding angle theorem

The 3x + 1 Conjecture asserts that, starting from any positive integer n, repeated iteration of this function eventually produces the value 1.

the 3X + 1 problem has appeared in various forms. It is one of the most infamous unsolved puzzles in the word. Prizes have been offered for its solution for more than forty years, but no one has completely and successfully solved it

Step-by-step explanation:

The 3x+1 problem concerns an iterated function and the question of whether it always reaches 1 when starting from any positive integer. It is also known as the Collatz problem or the hailstone problem

Answer:

Step-by-step explanation:

3x+1=0 /-1
3x=-1    /:3
x=-1:3

If you mean:
y = 3x+1 or f(x) = 3x+1

The x coordinate of the point is -5, the y coordinate point is 7, and the point is located on Quadrant II.

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

The coordinate point is:

(-5, 7)

As we know from the definition of the ordered double:

(x, y) represents the ordered double on the coordinate plane:

x = -5

y = 7

x < 0 and y > 0

The point is located on the Quadrant II

Thus, the x coordinate of the point is -5, the y coordinate point is 7, and the point is located on Quadrant II.

Answer:

The answer is 26 miles

Step-by-step explanation:

Ever .25 of an inch is 1 mile to multiply 6 by 4 and you'll get 24 and add 2 miles for the .5 .

The result of multiplying the polynomials is (2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

The polynomial expression is given as

(2x + 3) (-x + 2y - 4)

Expand the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = 2x * (-x + 2y - 4) + 3 * (-x + 2y - 4)

Open the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 8x + -3x + 6y - 12

Evaluate the like terms in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

Hence, the solution is -2x² + 4xy - 11x + 6y - 12

(a + b)² = 37

a^2 + 2ab + b^2 = 37

---

ab = 5

a = (5/b)

----

a^2 + 2ab + b^2 = 37

(5/b)^2 + 2(5/b)b + b^2 = 37

(25/b^2) + b^2 = 27

25 + b^4 = 27b^2

b^4 - 27b^2 + 25 = 0

So, the number of students in Band, Art, Music and Journalism are 2n, 7n+6, 4n-2 and 2(4n+6) respectively.

Since the number of students enrolled in Art and Music is equal to the number of students enrolled in Band and Journalism, we have the equation

7n + 6 + (4n-2) = 2n + 2(4n+6).

We now expand the brackets :
7n + 6 + 4n - 2 = 2n + 8n + 12
-> 11n + 4 = 10n + 12
-> 11n + 4 - 10n - 12 = 0
-> n - 8 = 0
-> n = 8.

Therefore, the number of students that enrolled in :
Band : 2n = 16 students.
Art : 7n + 6 = 62 students.
Music : 4n - 2 = 30 students.
Journalism : 8n + 12 = 76 students.

76 = 16 = 62 + 30 = 92, satisfying the requirement.

What is an equation?

A mathematical equation is a calculation that uses the identical sign to represent the equivalency of two variables. The definitions of the word equation and its cognates in various languages might vary slightly. For instance, in French, an equation is defined as having one or more variables, but in English, the equation would be any well-formed solution that comprises two variables linked by the assignment operator. Finding the values of the variables that result in the equality is the first step in solving an equation with variables. The unidentified variables are considered as the parameters for which the equation must be calculated, and the unknown perfect blend of shades that fulfill the equivalence are known as the equation's answers. Equations come in two varieties: assumptions and conditioned equations.

Given that rectangular house is 30 feet by 40 feet. Therefore, the  goat Cassidy is outside on a 50-foot-long leash that is connected to a corner of my house.

Therefore, Total area of the region in which the goat can roam is:

Step-by-step explanation:

To do this, we can substitute 3x+10x for f(x) and 2x-4 for g(x), and we get 13x-(2x-4). By distributing the negative to 2x-4, we just swap the signs, and get 13x-2x+4, which equals 11x+4

Also, is there supposed to be an exponent on the first f(x)? I'm not sure because I haven't seen the real problem.

(Otherwise it would just be f=13x.) Maybe try being a little more clear when asking a question :)
