Considering the situation with the parallel lines being cut by the two transversal lines, the measures of the angles are given as follows:
12. m<14 = 66º (option C).
13. m<12 = 86º (option D).
Measure of angle 14Angles 4 and 15 are alternate exterior angles, as they are on different sides of the same transversal line, hence they are congruent, that is:
m<15 = 114º.
Angles 14 and 15 are consecutive interior angles, meaning that they are supplementary, hence the measure of angle 14 is calculated as follows:
m<14 + m<15 = 180º
m<14 + 114º = 180º
m<14 = 66º.
Measure of angle 12Angles 5 and 10 are alternate interior angles, as they are on the opposite internal sides of the same transversal line, hence they are congruent and the measure of angle 10 is given as follows:
m<10 = 86º.
Angles 10 and 12 are equivalent angles, as they are on the same position, just relative to different transversal lines, hence they are also congruent, and the measure of angle 12 is given as follows:
m<12 = 86º.

Look at the distance vs. elevation graph. Describe the relationship between distance and elevation. Does the relationship support the continental drift theory? Provide at least one piece of support for your answer by referencing your graph
The relationship has no relation to continental drift theory, as it is a relation between distance and time, not distance and elevation.
What is continental drift theory?The continental drift theory states that the world's tectonic plates are in constant motion over time.
This is supported by the fact that some millions of years ago, there was only one continent, named Pangea, and now we have the continents as we know. These continents are also moving a small amount a year.
In this problem, the elevation decreases and the distance increases, however, the continental drift theory should have the distance increasing or decreasing over time, hence the graph relationship has no relation to the continental drift theory.

What do you mean by congruent?In geometry, the two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into the one another by an isometry, which is a combination of rigid motions like translation, rotation, and reflection. This indicates that either object may be precisely aligned with the other object by moving and reflecting it, but not by resizing it. So if we can cut out and then perfectly match up two separate plane figures on a piece of paper, they are congruent. The paper may be turned over.
Triangles with two pairs of congruent sides and an included congruent angle are said to be congruent by ASA.
According to the graph, sides TU, FG, and BC are congruent, as well as sides TV, HG, and AB. Additionally, it shows that angles G and B are congruent as well as angles U, F, and C. Triangle TUV is eliminated because ASA cannot find another triangle that is equivalent to angle U of triangle TUV using the information provided.

Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w=0.75f . What does 0.75 tell us in this situation?
If the number of cups of water w, needed for f cups of flour is described by the equation w = 0.75f, 0.75 represents the number of cups of water needed for one cup of flour
The equation is
w = 0.75f
Where w is the number of cups waters needed for f cups of flour.
Here w is is dependent variable and f is the independent variable
We can see that w is proportional to the f, the 0.75 is the constant.
w = 0.75f
Move the f to left hand side of the equation
w/f = 0.75
Hence, If the number of cups of water w, needed for f cups of flour is described by the equation w = 0.75f, 0.75 represents the number of cups of water needed for one cup of flour

The probability that the mean age of a sample of 36 vehicles is between 98 and 100 months is 15.71%.
What exactly is the z-score?The Z-score indicates the measure's deviation from the mean.We analyze the z-score table after deciding the Z-score to ascertain the p-value associated with this z-score.This p-value symbolizes the likelihood that the value of the measure is less than X, or even the percentile of X.For the given question;
The data for the vehicles registered in the united states is given as-
mean μ = 196 monthsstandard deviation σ = 15 monthssample mean x = 98 and 100 monthsSample size n = 36 vehicles.The formula for the z score is-
z = (x - μ)/(σ/√n)
Put the values.
√n = √36 = 6
For x = 98 months
z = (98 - 96)/(15/6)
z = 0.8
p(z < 0.8) = 0.7881
For x = 100 months
z = (100 - 96)/(15/6)
z = 1.6
p(z < 1.6) = 0.9452
P(0.8<x<1.6) = 0.9452 - 0.7881
P(0.8<x<1.6) = 0.1571

Find the value of “B,” that will make a perfect square trinomial. x² + Bx + 1.
*
Type the answer for B as a whole number.
Using algebraic identities, we found that for B=2 and B= -2 , the trinomial x² + Bx +1 makes a perfect square.
What are algebraic identities?Algebraic identities are the identities which aids in solving products or powers of algebraic expressions. Most common identities are :
(a+ b)² = a² + 2ab + b²
(a- b)² = a² - 2ab + b²
a² -b² = (a+ b) (a- b), where a and b can be variable or constants or algebraic expressions.
Let the perfect square of the trinomial be (x +a)²
x² + Bx +1 = (x+ a)² = x² + 2xa + a² (using identity (a+ b)² = a² + 2ab + b²)
⇒ x² + Bx +1 = x² + 2xa + a²
⇒ Bx = 2xa , a² =1
⇒B = 2a , a =± 1
if a =1 ⇒ B = 2
If a = -1 , B = -2
For B = 2 , x² + Bx +1 = x² + 2(1)x +1² = (x+1)² ( ∵(a+ b)² = a² + 2ab + b²)
For B = -2 , x² + Bx +1 = x² -2x + (-1)² = x² -2x +1 = ( x-1)² (∵(a- b)² = a² -2ab

A plane flies 1.7 hours at 140 mph on a bearing of 10 degrees. It then turns and flies 9.6 hours at the same speed on a bearing of 100 degrees. How far is the plane from its starting point?
The starting point is 1,365 miles .
Given :
→ initial time of plane = 1.7 hours
→ initial speed = 140 mph
→ final time of plane = 9.6 hours
→ final speed = same = 140 mph
The initial displacement of the plane is :
distance = speed × time
= 1.7 × 140
= 238 miles
The final displacement of the plane is :
distance = 9.6 × 140
= 1,344 miles
The angles between initial and final displacement is :
100° - 10 ° = 90 °
The distance of the plane from its starting point is calculated as follows

Answer:
=(3x - 2y( (4x - 3y)
Step-by-step explanation:
We have,
12x2 – 17xy + 6y2
The coefficient of x2 is 12
The coefficient of x is -17y
Constant term is 6y2
So, we express the middle term -17xy as -9xy – 8xy
12x2 -17xy+ 6y2 = 12x2 – 9xy – 8xy + 6y2
= 3x (4x – 3y) – 2y (4x – 3y)
= (3x – 2y) (4x – 3y)
what are the coordinates of point E
Step-by-step explanation:
E = (-8, 2)
reflected across the y axis means that there is kind of a mirror along the y-axis.
and when you look into that mirror, you see point D as point E all the way on the other side of the mirror, at the same distance from the mirror as point D is. and point E has the same "height" (y) as point D.
since the other side of the mirror represents the negative numbers, the same distance to the mirror means the same amount of negative units away from the mirror for E, as we have positive units away from the mirror for D.
