According to the alternate angle theorem, when a transversal cuts two parallel lines, the resulting alternate interior angles or alternate exterior angles are congruent. To demonstrate: If a transversal cuts two parallel lines, then the opposing interior angles are equal.

Two angles are said to be congruent when they are equal to each

The equation that represent the situation in slope intercept form is y = -0.1075x + 32.7.

'

Equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

As you drive, the number of minutes since you filled the tank and the number of gallons remaining in the tank are related by a linear function.

After 40 minutes, you have 28.4 gallons left. An hour after filling up, you have 26.25 gallons left.

Let's find the slope.

(40, 28.4)(60, 26.25)

m = 26.25 - 28.8 / 60 - 40

m = -2.15 / 20

m = - 0.1075

Hence, let's find the y-intercept using (40, 28.4)

y = - 0.1075x + b

where

Therefore,

28.4 = -0.1075(40) + b

28.4 + 4.3 = b

b = 32.7

Therefore, the equation of the line is y = -0.1075x + 32.7

Answer:

$1.60

Step-by-step explanation:

20% of $8.00 is actually 0.20 x 8

0.20 x 8 = 1.60

Answer:

$1.60

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20

Second, you need to find out what 20% of your $8.00 meal cost is.This is always done by multiplying 0.20 by $8.00, or

0.20 x $8.00=$1.60.

So, the amount of tip you are going to leave is $1.60.

The first step in solving the inequality is -12 + 20x ≥ -6x + 9

An inequality can be defined as a relationship that shows a non-equal comparison between two numbers or mathematical expressions.

Given the inequality

–4(3 – 5x)≥ –6x + 9

Solving the inequality

⇒-12 + 20x ≥ -6x + 9

Keeping all x on one side it can be written ,

⇒20x + 6x ≥ 12 + 9

Adding both sides,

⇒26 x ≥ 21

divide both sides by 26,

⇒x ≥ 0.80

Answer: No triangle lengths have to add all three length together to equal 180 like 60 60 60 or 90 80 10

Step-by-step explanation:

The value of x is 7.2.

The Perimeter of quadrilateral TWNB is 70.

what is perimeter?

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

Given:  TWNB ≅ RDHY

NW = 3x,

RD = 5x - 19.6

RY = 2x + 5.6

HD = 5x - 14.4

TW = 3x - 5.2

BN = x + 4.8

We have to find the value of x

As, TWNB ≅ RDHY

⇒ TW ≅ RD,  WN ≅ DH,  NB ≅ HY,  TB ≅ RY

Consider, TW ≅ RD

  3x - 5.2 = 5x - 19.6

19.6 - 5.2 = 5x - 3x

       14.4 = 2x

           x = 7.2

Hence, the value of x is 7.2.

Now to find the perimeter of quadrilateral TWNB.

Perimeter of TWNB = TW + WN + NB + TB

Here,

TW = 3x - 5.2 = 16.4

WN = 3x = 21.6

NB = x + 4.8 = 12

TB = RY = 2x + 5.6 = 20

Hence,

Perimeter of TWNB = 16.4 + 21.6 + 12 + 20 = 70.

What is Arithmetic sequence?

Arithmetic sequences are collections of integers where the distance between succeeding items is consistently the same.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is always the same. In this case, the difference between the two terms is 16 - 4/8 = 12.

So the sequence could be written as 4/8, 4/8 + 12, 4/8 + 2*12, ... and so on. Each term in the sequence is obtained by adding 12 to the previous term.

Therefore  ,the probability that in a given year exactly two mountain lions will be seen in this wilderness area is P =0.2417.

Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. When an event has a probability of 0, it has no possibility of happening, whereas when it has a probability of 1, it is almost certain to happen. When an event has a probability of 0.45 (45%), there are 45 out of 100 chances that it will occur.

Here,

λ=1.2

=> P(X =x) = [tex]\frac{e^{-\lambda} * \lambda^{x} }{x!}[/tex]

=> P(X=2) = [tex]\frac{e^{-1.4} * 1.4^{2} }{2!}[/tex]

In linguistics, dynamic semantics is a theory of meaning that is based on the idea that the meaning of a sentence is determined by the way it is used in context, rather than by its compositionality. Within dynamic semantics, there are a few different approaches that have been developed. Three types of dynamic semantics are Discourse representation theory, situation semantics and event semantics.

Discourse representation theory: This theory proposes that the meaning of a sentence is determined by its role in the context of a discourse (i.e., a conversation or written text). The meaning of a sentence is represented as a set of constraints on the possible interpretations of the discourse, and the interpretation of the discourse is determined by the way these constraints are resolved.

Situation semantics: This theory proposes that the meaning of a sentence is determined by the way it refers to a particular situation or state of affairs. The meaning of a sentence is represented as a set of conditions that must be satisfied for the sentence to be true in a particular situation.

Event semantics: This theory proposes that the meaning of a sentence is determined by the events or actions it describes. The meaning of a sentence is represented as a set of conditions that must be satisfied for the events or actions described in the sentence to occur.

The instantaneous rate at the beginning of a reaction, or when t = 0, is known as the starting rate of the reaction.

The rate at the beginning of the reaction may be determined using the graph of change in product over time or change in reactant over time. The highest rate on the curve is the beginning rate. Since the reactants are concentrated at their highest at the beginning, the most collisions are occurring.

Rates of response can be depicted in graphs. To depict the pace of reaction, we may create a graph of product (or reactant) against time. The pace of reaction will be the gradient of the graph. The pace of response increases with increasing gradient steepness.

The instantaneous rate at the beginning of a reaction, or when t = 0, is known as the starting rate of the reaction. The beginning rate is equal to the slope of the reactant concentration versus time curve at time zero, which is negative.

Geometric shapes that are identical in size and shape are known as congruent figures. Congruent figures are those in which you may use a series of translations, rotations, and/or reflections to turn one figure into another.

The separation between each pair of the geometric object's points is preserved during a rigorous change of the object. In other words, a rigid transformation maintains the object's size and shape. For instance, the rigid transformation of a triangle retains the angles and lengths of the triangle. Imagine a stiff shape distortion, similar to a cardboard shape.

There are isometric rotations, reflections, and translations. Accordingly, the size of the figure is unaffected by these adjustments. The figures are consistent if neither the size nor the form of the figure is altered.

Generally, To solve this system of equations by graphing, you can start by graphing each equation separately on the same set of axes.

For the first equation, Y = x - 1, you can start by plotting a few points to get a feel for the graph.

, if x = 0, then Y = -1.

If x = 1, then Y = 0.

If x = 2, then Y = 1.

You can continue plotting points like this to get a better idea of what the graph looks like.

For the second equation, y = 1/2x + 1, you can do the same thing. For example,

if x = 0,

then y = 1.

If x = 1,

then y = 1.5.

If x = 2,

then y = 2.

Again, you can plot a few more points to get a better sense of the graph.
