which pairs of angles are not always congruent when two parallel lines are cut by a transversal?
A. Vertical lines
B. Alternate exterior angles
C.corresponding angles
D. Consecutive interior angles
When two parallel lines are cut by a transversal vertical lines are not always congruent.
What are transversal?A line that goes through two lines in the same plane at two different points is called a transversal. When determining whether two or more other lines in the Euclidean plane are parallel, transversals play a role. Different kinds of pairs of angles are created when two lines intersect a transversal: alternate angles, corresponding angles, consecutive exterior angles, and consecutive interior angles. If the two lines are parallel, Euclid's parallel postulate states that consecutive interior angles are supplementary, that corresponding angles are equal, and that alternate angles are equal.
Given to find the pairs of angles are not always congruent when two parallel lines are cut by a transversal,
when parallel lines are cut by a transversal some pair of angles are congruent like alternative exterior angle, corresponding angles and
Consecutive interior angles all the pairs are congruent and equal.
but When a transversal line cuts through two parallel lines, vertical lines are not always congruent.
Therefore vertical lines are not always congruent.

Which of these is false?
A) 21,730 < 22,341
B) 21,730 > 22,341
C) 22,341 > 21,730
D) 22,341 < 24,687
The false statement among the given options is B) 21,730 > 22,341. The greater than, less than symbols should be accurately used to compare two numbers. The other given statements are true.
Explanation:The false statement in the given options is B) 21,730 > 22,341. This statement is saying that 21,730 is greater than 22,341, which is false. In mathematics, '<' symbol represents 'less than' and '>' represents 'greater than'. So, the statement B) is false because 21,730 is not greater than 22,341, but less.
Comparing the following two statements A) 21,730 < 22,341 and C) 22,341 > 21,730, we can see they are actually the same statement, restated in a different manner. Both statements are saying that 21,730 is less than 22,341 which is true.
The statement D) 22,341 < 24,687 is also true because 22,341 is less than 24,687.

Suppose the tree diagram below represents all the students in a high school and that one of these students were chosen at random. If the student is known to be a girl, what is the probability that the student is right-handed?
A. 1/4
B. 3/4
C. 5/6
D. 1/6
The Answer is C 5/6
250/300 reduced and simplified is 5/6
Answer:
The probability that the student is right-handed given that the student is a girl is:
[tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
From the tree diagram we have to find the probability that the students is right handed given that the student is a girl.
Let A denote the event that the student is a girl.
and B denote the event that the student is right handed.
We are asked to find the probability:
P(B|A)
We know that P(B|A) is calculated as:
[tex]P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}[/tex]
There are a total of 500 students.
Out of which 300 are girls.
( i.e. [tex]P(A)=\dfrac{300}{500}=\dfrac{3}{5}[/tex] )
and out of 300 girls 250 are right handed.
( i.e. [tex]P(A\bigcap B)=\dfrac{250}{500}=\dfrac{1}{2}[/tex] )
Hence,
[tex]P(B|A)=\dfrac{\dfrac{1}{2}}{\dfrac{3}{5}}\\\\\\P(B|A)=\dfrac{5}{6}[/tex]
Hence,The probability that the student is right-handed given that the student is a girl is:
[tex]\dfrac{5}{6}[/tex]
An angle measures 29° . what is the measure of its complement?
The measure of the complementary angle will be 61°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
An angle measures 29°.
Let 'x' be the complementary angle. Then the measure of the complementary angle is given as,
x + 29° = 90°
Simplify the equation, then we have
x + 29° = 90°
x = 61°
The measure of the complementary angle will be 61°.

Numbers can be written in exponential form with a base of 10. For example, 100 is written as 10^2, 100,000 as 10^5, and 10,000 as 10^4.
Explanation:To write numbers in exponential form, you need to understand the concept of exponential notation which is a way to express a number as a base raised to a power. In each of the given cases, the base is 10.
For 100, there are two zeros following the 1. This means that 100 can be written as 10 to the power of 2, or 10^2.
Similarly, for 100,000, there are five zeros following the 1. This would be written as 10 to the power 5, or 10^5.
Lastly, 10,000, has four zeros following the 1. This would be written as 10 to the power of 4, or 10^4.

To have an inverse function, a function must be bijective, meaning it is both one-to-one (injective) and onto (surjective). An example is shown with the function f(x) = x^2 which is not injective, hence doesn't have an inverse function.
Explanation:In mathematics, to have an inverse function, the original function, represented as f, must be both injective (one-to-one) and surjective (onto). This dual property is called being bijective. This means every element of the function's domain maps to one distinct element in the function's range (injective) and that every element in the range has a pre-image in the domain (surjective).
For example, consider the function f(x) = x^2. This function is not injective, as both f(-2) and f(2) give the same output, hence it does not have a true inverse function across all real numbers.

?
The measure of angle <0 in the right triangle is approximately 30 degrees.
Explanation:To find the measure of angle <0 in the right triangle, we can use trigonometry. The side opposite to angle <0 is given as 5 inches. The hypotenuse is given as 10 inches. We can use the sine ratio to find the angle:
sin(<0) = opposite/hypotenuse
substituting the given values:
sin(<0) = 5/10 = 0.5
Now, to find the measure of angle <0, we can use the inverse sine function:
<0 = arcsin(0.5)
Using a calculator, we find that the measure of angle <0 is approximately 30 degrees.

if a 40-foot tree casts a 12-foot shadow, find the length of the shadow cast by a 28-foot tree
12/40 =0.3
28 *0.3 = 8.4
it will cast a 8.4 foot long shadow
Answer:
The shadow cast by a 28-foot tree is 8.4 foot.
Step-by-step explanation:
The rule of three is a way of solving problems of proportionality between three known values and one unknown, establishing a relationship of proportionality between all of them. In the case of direct proportionality, when one magnitude increases, the other increases ( or if one magnitude decreases, the other will also decrease)
This is an example of application of this rule:
40 foot tree ⇒ 12 foot shadow
28 foot tree ⇒ x foot shadow
Then, to solve and calculate the value of x, which is the value of the shadow cast by the 28-foot tree, perform the count:
x=[tex]\frac{28*12}{40}[/tex]
x=[tex]\frac{336}{40}[/tex]
x=8.4
This means that the shadow cast by a 28-foot tree is 8.4 foot.
What two numbers multiply to -30 and add to 1?
The products of two numbers involves multiplying them.
The two numbers are -5 and 6
Let the numbers be x and y.
So, we have:
[tex]\mathbf{x \times y = -30}[/tex]
[tex]\mathbf{x + y = 1}[/tex]
Make x the subject in [tex]\mathbf{x + y = 1}[/tex]
[tex]\mathbf{x = 1 - y}[/tex]
Substitute [tex]\mathbf{x = 1 - y}[/tex] in [tex]\mathbf{x \times y = -30}[/tex]
[tex]\mathbf{(1 - y)y = -30}[/tex]
Expand
[tex]\mathbf{y - y^2 = -30}[/tex]
So, we have:
[tex]\mathbf{y^2 -y - 30 = 0}[/tex]
Expand
[tex]\mathbf{y^2 -6y + 5y - 30 = 0}[/tex]
Factorize
[tex]\mathbf{y(y -6) + 5(y - 6) = 0}[/tex]
Factor out y - 6
[tex]\mathbf{(y + 5) (y - 6) = 0}[/tex]
Solve for y
[tex]\mathbf{y = -5\ and\ 6}[/tex]
Hence, the two numbers are -5 and 6
