Identify the pairs of alternate exterior angles in the given figure.
Question 14 options:
A)
∠3 and ∠6; ∠4 and ∠5
B)
∠2 and ∠7; ∠1 and ∠8
C)
∠3 and ∠5; ∠4 and ∠6
D)
∠1 and ∠7; ∠2 and ∠8
Answer: Choice D
Angle 1 and angle 7Angle 2 and angle 8=========================================================
Explanation:
The angles 3,4,5,6 are all considered interior angles because they are inside or between the parallel lines.
The remaining angles 1,2,7,8 are exterior angles as they outside the parallel lines. You can think of angles 3,4,5,6 being in the river or a road, while the other angles are on the sidewalk or the shoreline.
Alternating angles are ones that are on either side of the transversal cut.
Combining the two ideas leads to alternate exterior angles being outside the parallel lines and on either side of the transversal. This applies to the following pairs:
angle 1 and angle 7angle 2 and angle 8This is why choice D is the answer.

Susan's elevation at the top of a mountain is 1,530 meters. After 4 hours of climbing down her elevation is 680 meters. What is Susan’s average change in elevation, in meters per hour
A) -850
B)-382.50
C) -212.5
D) -167.5
Rate of a quantity is always in comparison to some other quantity's change. Susan’s average change in elevation, in meters per hour is given by: Option C) -212.5 meters/ hour.
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
(its final value - initial value for both dependent and independent variable).
The average change in elevation in meters per hour is ratio of change in elevation in meters to time taken to do it in hours.
Therefore, it is calculated as:
[tex]A = \dfrac{ 680 - 1530}{4} = \dfrac{-850}{4} = -212.5 \: \rm meters/hour[/tex]
(if t was initial time, and t+4 was final time, then t+4-t = 4)
(also, initial height was 1530
Thus, Susan’s average change in elevation, in meters per hour is given by: Option C) -212.5 meters/ hour

eden bought 2 1/4 meter of cloth. She uses 3/4 of meter for her project.how many meters of cloth did she have left
Rina bought 51/4 meter of cloth. She uses 3 3/4 of meter for her project.how many meter of cloth dis she have left
Answer:
1 1/4
1 1/2
Step-by-step explanation:
Given that :
Length of cloth purchased = 2 1/4
Length used for project = 3/4
Length remaining = (length purchased - length used)
= 2 1/4 - 3/4
= (9/4 - 3/4)
= (9 - 4) / 4
= 5/4
= 1 1/4
Length of cloth purchased = 5 1/4
Length used for project = 3 3/4
Length remaining = (length purchased - length used)
= 5 1/4 - 3 3/4
= 21/4 - 15/4
= (21 - 15) / 4
= 6/4
= 1 2/4
= 1 1/2

To avoid an additional charge, the sum of the length, l, width, w, and depth, d, of a piece of luggage to be checked on a commercial airline can be at most 61 inches.
a.
l + w + d greater-than 61
b.
l + w + d less-than 61
c.
l + w + d greater-than-or-equal-to 61
d.
l + w + d less-than-or-equal-to 61
Answer:
[tex]l + w + d \leq 61[/tex]
Step-by-step explanation:
Given
Sum of l, w and d be at most 61
Required
Write as inequality
First, we need to determine the sum of l, w and d
[tex]Sum = l + w + d[/tex]
Next, we determine the type of inequality.
At most 61 means less than or equal to 61
So, the expression becomes:
[tex]Sum \leq 61[/tex]
Substitute value for Sum
[tex]l + w + d \leq 61[/tex]

Mr. Burns measured the heights of 16 apple trees in his orchard. The results are shown in the
dot plot. Which statement about the data is true?
Answer: The 3rd answer on your screen in correct :) imagine cheating
Step-by-step explanation:
Mr. Diaz has 92 peach trees in his orchard which he planted along with apple trees.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
here, we have,
Given, Mr. Diaz has 346 apple trees in his orchard.
Let, 'P' denotes the number of peach trees and 'A' denotes the number of apple trees.
So, A + P = 347.
Also given that he has 162 more apple trees than peach trees in his orchard which is, A = P + 162.
Therefore,
P + 162 + P = 346.
2P = 346 - 162.
2P = 184.
P = 92.
So, Mr. Diaz has 92 peach trees in his orchard.
Q. Mr. Diaz has 346 apple trees in his orchard. He has 162 more apple trees than peach trees in his orchard. How many peach trees does Mr. Diaz have in his orchard?

If x^2+y^2=1, what is the largest possible value of |x|+|y|?
If x² + y² = 1, then y = ±√(1 - x²).
Let f(x) = |x| + |±√(1 - x²)| = |x| + √(1 - x²).
If x < 0, we have |x| = -x ; otherwise, if x ≥ 0, then |x| = x.
• Case 1: suppose x < 0. Then
f(x) = -x + √(1 - x²)
f'(x) = -1 - x/√(1 - x²) = 0 → x = -1/√2 → y = ±1/√2
• Case 2: suppose x ≥ 0. Then
f(x) = x + √(1 - x²)
f'(x) = 1 - x/√(1 - x²) = 0 → x = 1/√2 → y = ±1/√2
In either case, |x| = |y| = 1/√2, so the maximum value of their sum is 2/√2 = √2.
An equation is formed of two equal expressions. The largest possible value of |x|+|y|=1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the value of x²+y²=1. Therefore, The largest possible value of |x|+|y|=1.
