Answer:

2.25 yards per quilt

Step-by-step explanation:

if you add up all the numbers u get 58.5. then divide this by 26 to get 2.25

The number of yards that are used for each quilt will be 2.25 yards.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Dan is making quilts for the sewing class. He will utilize 22 yards of yellow texture, 11.2 yards of green texture, and 25.3 yards of blue texture. This sum makes 26 blankets.

The number of yards that are used for each quilt will be given as,

⇒ (22 / 26) + (11.2 / 26) + (25.3 / 26)

⇒ (22 + 11.2 + 25.3) / 26

⇒ 58.5 / 26

⇒ 2.25 yards

The number of yards that are used for each quilt will be 2.25 yards.

Answer: 45°

Step-by-step explanation:

Angles of a triangle always add up to 180°.

So to work out what x is you would have to add 110° and 25° then take it away from 180°

110+25=135°

180-135=45°

Hope this helps :)

Answer:

It is 45

Step-by-step explanation:

The whole triangle is 180 so adding 110 plus 25 will get you 135. Then subtract 180 from 135 to get 45

Answer:

When you read a sentence, you may first look for the subject or what the sentence is about. The subject usually appears at the beginning of a sentence as a noun or a pronoun. A noun is a word that identifies a person, place, thing, or idea. A pronoun is a word that replaces a noun. Common pronouns are I, he, she, it, you, they, and we. In the following sentences, the subject is underlined once.

Step-by-step explanation:

You will often read a sentence that has more than one noun or pronoun in it. You may encounter a group of words that includes a preposition with a noun or a pronoun. Prepositions connect a noun, pronoun, or verb to another word that describes or modifies that noun, pronoun, or verb. Common prepositions include in, on, under, near, by, with, and about. A group of words that begin with a preposition is called a prepositional phrase. A prepositional phrase begins with a preposition and modifies or describes a word. It cannot act as the subject of a sentence. The following circled phrases are examples of prepositional phrases.

Step-by-step explanation:

The value of x in the quadratic equation is -0.12 or 3.12.

The value of x in the quadratic equation is calculated as follows;

h(x) = -16x² + 48x + 6

Using formula method, the value of x is calculated as;

x = (-b ± √(b² - 4ac)) / 2a

Where;

a = -16, b = 48, c = 6

x = (-48 ± √(48² - 4(-16)(6))) / 2(-16)

x = (-48 ± √(2304 + 384)) / (-32)

x = (-48 ± √(2688)) / (-32)

x = (-48 ± 51.85) / (-32)

x = (-48 + 51.85)/(-32)  = - 0.12

or

x = (-48 - 51.85)/(-32) = 3.12

Smallest element in the set of range is -3

Step-by-step explanation:

From the given set of ordered pairs,

x-value of each pair represents the Domain of the relation.

y-value of the pair represents the Range of the relation.

Set of domain:

{0, 1, 2, 3, 4, 5, 6}

Set of Range:

{1, 3, 2, 5, 2, -3, 2}

Smallest number in the set of range = -3.

Therefore, smallest element in the set of range is -3.

Using the formula for the midpoint of the line with given points  A and B as the end points of the line, the coordinates of the point B is (6,-8).

To find the midpoint of a line segment, you must first find the coordinates of the two endpoints of the segment. Then, take the average of the x-coordinates and the y-coordinates to find the x and y coordinates of the midpoint. This can be done by adding the x-coordinates and y-coordinates of the two endpoints together and then dividing by 2.

What is the formula for finding the midpoint of a line segment?

The formula for finding the midpoint of a line segment is:

Midpoint = ( (x1+x2)/2 , (y1+y2)/2 )

Where (x1,y1) and (x2,y2) are the coordinates of the two endpoints of the line segment.

Using the given coordinates of point A(8,-6) and the midpoint M(7,-7) of the line,  and using the midpoint formula for a line AB,

Midpoint(M) = \((\frac{x1+x2}{2},\frac{y1+y2}{2} )\)

where x1, y1 are coordinates of point A , and x2, y2 are the coordinates of point B

so , (7,-7) = \((\frac{8+x2}{2} , \frac{-6+y2}{2})\)

equating the corresponding points,

7 =(8+x2)/2

therefore, x2 = 6

and , -7 = (-6+y2)/2

therefore , y2 = -8

Hence the coordinates of B is , (x2,y2 ) = (6,-8)

\(f(x) = 3(x - 1)^2-3\)

Step-by-step explanation:

Given

\(f(x) = 3x^2 - 6x + 6\)

Required

Write as:

\(f(x) = a(x - h)^2 + k\)

In \(f(x) = 3x^2 - 6x + 6\), the coefficient of x is -6

Divide by 2: -3

Square: 9

Add 9 - 9 to the above equation

\(f(x) = 3x^2 - 6x +9-9+ 6\)

Split to 2

\(f(x) = [3x^2 - 6x +9]-[9- 6]\)

\(f(x) = [3x^2 - 6x +9]-[3]\)

Factorize:

\(f(x) = [3x^2 - 3x -3x+9]-[3]\)

\(f(x) = [3x(x - 1) -3(x-1)]-[3]\)

\(f(x) = [(3x - 3)(x-1)]-[3]\)

Factorize 3x - 3

\(f(x) = [3(x - 1)(x-1)]-[3]\)

\(f(x) = 3(x - 1)^2-[3]\)

\(f(x) = 3(x - 1)^2-3\)

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Small rooms are denoted as S.

Large rooms are denoted as L.

Now,

We will make two equations.
L = 2S _____(1)

Answer:

To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:

Sales tax = 0.03 x $16.05 = $0.48

To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:

Total bill = $16.05 + $0.48 = $16.53

To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:

Tip = 0.18 x $16.53 = $2.98
