The converse of corresponding angles theorem that proves that p║r is stated in the proof explained below (see proof below).
What is the Converse of Corresponding Angles Theorem?If two corresponding angles are congruent to each other, the converse of the corresponding angles theorem states that the lines on which both corresponding angles lie are parallel to each other.
What is the Vertical Angles Theorem?The vertical angles theorem is the theorem that justifies that when two angles are vertically opposite to each other, then they are congruent angles.
Given that, angle 1 is congruent to angle 5, to prove that lines p and r are parallel to each other, the statements and reasons stated below explains why they are parallel lines:

The values of A, B and C are 36, 7 and 3, respectively.
What is the simplified form of the sum of two positive integers?
In this problem we have the addition of two positive integers that are divisible to 2. First, we proceed to decompose each element of the addition as a product of prime numbers:
252 = 2² × 3² × 7
108 = 2² × 3³
The greatest common factor is the greatest integer that can be removed from the addition by distributive property. Then, the greatest common factor is 2² × 3² = 36 and finally:
(2² × 3²) · (7 + 3)
36 · (7 + 3)

On his first three tests Al averaged 76 out of 100.
What score out of 100 must he get on the fourth
test so his average will be 81?
Answers
Al must score 96 in his final test to get an average of 81.
An average or mean is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group.
If every number in a list is the same number, then the average of the numbers in the list is also this number. Every one of the diverse varieties of average shares this characteristic.
The sum of the of the numbers 2, 3, 4, 7, and 9 is 25, the average of the numbers is equal to 25 divided by 5=5.
Let Al scores x on final test.
Average score on first 3 tests=76
Total score on first 3 tests=76×3=228
Total score in 4 tests=228+x
Average score of 4 tests=(228+x)÷4
Average to be obtained in 4 tests=81
therefore we can equate the two expressions to calculate x.
(228+x)÷4=81
or, 228+x=324
or,x=324-228
or, x=96
Hence Al needs to get 96 on his final test so that his average is 81.

w + 5w + 4 = 3(2w − 1)
Answers
Answer:
my result is 0 = -7 It has no solutions though since it is a contradiction
w + 5w + 4 = 3(2w - 1)
Now, let’s combine like terms:
6w + 4 = 3(2w - 1)
Now, let’s distribute:
6w + 4 = 6w - 3
Our next step is to isolate the variable on the left side. To do so, we can subtract 4 from both sides:
6w + (4 - 4) = 6w - 3 - 4
Now, we can simplify:
6w = 6w - 7
Let’s subtract 6 from all sides:
6w - 6w = 6w - 7 - 6w
0 = 0 - 7
0 = -7
This expression has no solutions; 0 will never equal -7. Hence, we have no solutions.
3. juan lies on the ground 45 feet from his tent. the tent is 400 feet from the base of a tall cliff. both the top of the tent and the top of the cliff are in his line of sight. if juan's tent is 10 feet tall, how tall is the cliff?
Answers
The cliff is 98.89 feet tall.
In the attached diagram, we can there are two triangles forming. Small triangle involves Juan and tent and larger triangle involves Juan and cliff. As per the known fact, tan theta = perpendicular ÷ base. So, tan theta will be common for both the triangles. Hence, relating the components of tan theta, of both the triangles.
Smaller triangle :
tan theta = 10/45
Larger triangle :
tan theta = h/(400 + 45)
tan theta = h/445
Relating both the triangles as follows -
10/45 = h/445
Performing cross multiplication
10×445 = h×45
h = 4450÷45
h = 98.89 feet
Hence, the cliff is 98.89 feet tall.

The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2
How to complete the arithmetic sequence?The arithmetic sequence is given as:
1, .25, blank, -1.25, blank
Replace the blanks in the arithmetic sequence with x and y
So, we have:
1, .25, x, -1.25, y
An arithmetic sequence has a common difference (d)
The common difference is calculated using
d = T2 - T1
So, we have
d = 0.25 - 1
d = x - 0.25
d = y + 1.25
Substitute d = x - 0.25 in d = 0.25 - 1
x - 0.25 = 0.25 - 1
This gives
x = 0.25 + 0.25 - 1
Evaluate the sum
x = -0.5
Substitute d = 0.25 - 1 in d = y + 1.25
0.25 - 1 = y + 1.25
This gives
y = 0.25 - 1 - 1.25
Evaluate

Write an equation of the line and interpret the slope and y intercept (Will award brainiest answer)
Answers
Answer:
[tex]y = 120x [/tex]
Step-by-step explanation:
Equation of a straight line is
[tex]y = mx + b[/tex]
m= slope of line = rise/run which can be computed by taking two points on the line, finding the difference I the y coordinate values and dividing by the correspoding difference in their x coordinate values
b is the y-intercept where the line crosses the y-sxis
Looking at the graph we can see that the line crosses the y-sxis at the origin (0, 0) so the y-intercept is at y=0
The slope is determined by examining the two highlighted points (3, 360) and (2, 240)
Slope =
[tex] \frac{360 - 240}{3 - 2} = \frac{120 }{1} = 120[/tex]
So equation of line is

a) Write her times in tolerance notation as in (.... ± ...) minutes.
b) Now calculate her tolerance using percentages as.... mins (± ...%).
Answers
Using the percentage concept, it is found that:
a) Her tolerance is of (60 ± 6 minutes).
b) As a percentage, her tolerance times are of 60 minutes (± 10%).
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
For this problem, the interval is between 54 and 66 minutes, that are both within 6 minutes of the mean of 60 minutes, thus:
a) Her tolerance is of (60 ± 6 minutes).
For item b, we want to find the tolerance as a percentage, that is, the percentage that the tolerance of 6 minutes is from the time of 60 minutes, hence:
P = 6/60 x 100% = 0.1 x 100% = 100%.
Hence:
b) As a percentage, her tolerance times are of 60 minutes (± 10%).
