Answer:

133

Step-by-step explanation:

The two angles add to a straight line

PQR + RQS = PQS

3x-5 + x+1 = 180

Combine like terms

4x -4 =180

Add 4 to each side

4x -4+4 = 180+4

4x =184

Divide each side by 4

4x/4 =184/4

x =46

We want to find PQR

PQR = 3x-5

      = 3*46 - 5

    = 138 -5

    = 133

Using proportions, it is found that one sandwich costs $4.25.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Considering x as the cost of a sandwich, the total cost is given as follows:

1.08(3x + 1.75) + 5 = 20.66.

The multiplication by 1.08 is because of the sales tax. We solve for x to find the cost of one sandwich, hence:

1.08(3x + 1.75) = 15.66

3x + 1.75 = 14.5

3x = 12.75

x = 12.75/3

x = 4.25.

Hence one sandwich costs $4.25.

Answer:

D.

Step-by-step explanation:

D. is the binomial since it has 2 terms.

The number is 48.

Let's represent the two-digit number as 10x + y, where x is the tens digit and y is the units digit.

According to the given information, the units digit is twice the tens digit. So we have the equation:

y = 2x

If the number is doubled, it will be 12 more than the number reversed. When we double the number, we get 2(10x + y), and the number reversed is 10y + x.

Therefore, we can write the equation as:

2(10x + y) = 10y + x + 12

Simplifying this equation, we get:

20x + 2y = 10y + x + 12

19x = 8y + 12

19x - 8y = 12

We have two equations now:

y = 2x

19x - 8y = 12

Substituting the value of y from the first equation into the second equation, we get:

19x - 8(2x) = 12

19x - 16x = 12

3x = 12

x = 4

Now we can substitute the value of x back into the first equation to find y:

y = 2x

y = 2(4)

y = 8

The approximate height of the pole in centimeters is 17,500 centimeters.

We have,

Let's start by calculating the total length of the pole, which is buried plus the part that protrudes from the ground.

We know that the part that protrudes is 25 meters and that it represents one-seventh of the total length.

25 = L/7

where L is the total length of the pole.

We can solve for L by multiplying both sides of the equation by 7:

L = 7 x 25

  = 175 meters

Now we need to convert this length to centimeters.

Since 1 meter is equal to 100 centimeters,

175 meters x 100

= 17,500 centimeters

Therefore,

The approximate height of the pole in centimeters is 17,500 centimeters.

The statement refers to the way that symbols are represented in sequences, a common practice in formal language theory, by employing a notation that makes symbols a part of the sequence.

In formal language theory, a language is often defined as a set of strings over an alphabet. By representing any alphabetic sequence of symbols as a single string using the notation outlined in the statement, we are able to recognise the language that comprises that sequence as a collection of strings. A subset of the language having all possible strings over the alphabet (a, b, and c) is the set of strings abc, which may be used to represent the language including the sequence (a, b, and c). So, this notation offers an easy approach to discuss languages and the sequences that make up such languages.

The y-intercept of a function is the value of y when x = 0, which is represented as the value of b in the slope-intercept equation y = mx + b. b is the y-intercept.

If an equation of graph that represents a function is given in slope-intercept form as y = mx + b, the value of b in the function is the value of the y-intercept of the y-intercept.

The y-intercept of the function is the same as the value of y when the value of x is 0, or the point where the line of the function intercepts the y-axis on a given graph that represents the function.

For example, if we are given the equation of a graph that represents a function as, y = 3x + 4, the y-intercept of the function would be 4.

In summary, the y-intercept of the function is the value of b in the equation of the function that is expressed as y = mx + b in slope-intercept form.

Answer:

\(\pm i\sqrt{2}\text{ and } \pm i\)

Step-by-step explanation:

\(\text{let u = } x^2\) so then \(u^2=x^4\).

This gives you the equation: \(u^2+3u+2=0\).

Now factor the equation by looking for factors of 2 that add up to 3, which is just 2 and 1. Use these to rewrite the equation: \((u+2)(u+1)\). So now just set each factor equal to 0:

\(u+2=0\\u=-2\)

Now substitute x^2 back in as u

\(x^2=-2\)

Take the square root of both sides

\(x=\pm \sqrt{-2}\)

Separate the radical into sqrt(-1) * sqrt(2)

\(x=\pm \sqrt{-1}*\sqrt{2}\)

Rewrite using i

\(x=\pm i\sqrt{2}\)

Now set the other factor equal to 0

\(u+1=0\\u=-1\)

substitute x^2 back in as u

\(x^2=-1\)

Take the square root of both sides

\(x=\pm\sqrt{-1}\)

rewrite using i

\(x=\pm i\)

The Horizontal asymptotes is y = 2

Function are mathematical statement which links an independent variable to dependent variable. It always comes with a defined domain and range.

This function can be written as;

1/(x+2)-4

Since Vertical asymptotes are defined when the denominator of a rational function tends to zero.

We know that Horizontal Asymptote is when the function f(x) is tending to zero.

for x = +∞ and x = - ∞

Since b = a the horizontal asymptote is the line

y = m/n

Answer:

WY = 30

XZ = 10.5

Step-by-step explanation:

Paralellogram's diagonal's bisect eachother

Therefore,

\(n + 7 = 3 n\)

Move the n over,

2n = 7

Divide both sides by 2,

n = 3.5

WY = 2(ZY) because definition of bisector

Simplify...

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

You asked for XY, but the question asks for XZ, so I'm going to give XZ.

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

The measure of XY and WY are; WY = 30 and XZ = 10.5

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Since Paralellogram's diagonal's bisect each other

Therefore,

2n = 7

Divide both sides by 2;

n = 3.5

WY = 2(ZY)

because definition of bisector

Simplify;

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

we asked for XY,

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

We have to note that the radioactivity would have to do with the spontaneous disintegration of the material. In this case, we can see that we have the function that models the situation as;

R(t) = 6e^-0.18t Where t is the time that is taken

At first we have that the time is zero hence the R(t) is;

The measure of the angles formed between parallel lines and their transversals indicates;

9. m∠3 = 97°, m∠5 = 97°, m∠10 = 97°, m∠7 = 83°

Parallel lines are lines that  maintain the are equidistant from each other and have the same slope on the coordinate plane.

The angles formed between the parallel lines and their transversal are;

1. Alternate exterior angles; (c) ∠9 and ∠16
2. Supplementary angles (e);  ∠15 & ∠11

3. Alternate interior angles (a); ∠10 & ∠15

4. Vertical angles (d); ∠12 & ∠15

5. Corresponding angles (b); ∠9 & ∠11

6. None (f); ∠9 & ∠15

7. Supplementary angles (e); ∠13 & ∠14

8. Alternate interior angles; ∠14 & ∠11

9. The alternate interior angles theorem indicates that we get;

(a + 28) = 2·a

Therefore; 2·a - a = 28

2·a - a = a, therefore;

a = 28

∠MNP = (a + 28)° = (28 + 28)° = 56°

10. The alternate interior angles theorem indicates that we get;

5·y° = (2·y + 78)°

Therefore;

5·y - 2·y = 78

3·y = 78

y = 78/3 = 26

The measure of the angle WXZ, m∠WXZ = 5·y°

Therefore; m∠WXZ = 5 × 26 = 130

m∠WXZ = 130°

9. ∠2 ≅ ∠3 (Vertical angles theorem)

m∠2 = m∠3

Therefore; m∠3 = m∠2 = 97°

m∠5 + m∠6 = 180° (Linear pair angles theorem)

m∠5 + 83° = 180°

m∠5 = 180° - 83° = 97°

∠10 and ∠2 are corresponding angles, therefore;

m∠10 = m∠2 = 97°

∠7 and ∠6 are vertical angles, therefore;

m∠7 = m∠6 = 83°

∠9 and ∠3 are same side interior angles, therefore;

m∠9 + m∠3 = 180°

m∠9 = 180° - m∠3

m∠9 = 180° - 97° = 83°
∠8 and ∠6 are linear pair angles, therefore; m∠8 = 180° - 83° = 97°

∠16 and ∠6 are same side exterior angles, therefore;

m∠16 + m∠6 = 180°

m∠16 = 180° - 83° = 97°
