The question tells us ABCD ~ WXYZ, which means trapezoid ABCD is similar to WXYZ.
Point A corresponds to point W, B corresponds with X, C corresponds with Y, and D corresponds with Z (first, second, third, and last letters correspond with each other according to the similarity statement).
Now let's check each answer choice and see which applies to these similar trapezoids:
Since point B corresponds with point X and the trapezoids are similar, they must be congruent angles. Thus, the first choice is correct.Point Y does not correspond with point A. Thus, it is possible the angles are not congruent. The second choice is incorrect.Point A corresponds with W and B corresponds with X. Thus, line segment AB will be similar to line segment WX. However, they are not equal. Thus, the third choice is incorrect.There's an equal sign in this choice, too, just like the last, and the two segments are corresponding line segments. Thus, the fourth choice is incorrect.This looks like the third choice, but with a similarity symbol instead of an equal sign. Now, the statement is true and the fifth choice is correct.This looks like the fourth choice but with a similarity instead of an equal sign. Now, the statement is true and the sixth choice is correct.Let me know if you need any clarifications, thanks!

The Neolithic Revolution allowed people to live in permanent settlements.
Explanation:
The Neolithic Revolution is the phase of transition in which many of the human cultures in the world shifted their lifestyle to permanent settlement and agriculture from hunting and gathering.
This era is also named as First Agricultural Revolution or Neolithic Demographic Transition. The agricultural practices led the cultures to develop the knowledge of domestication of animals and they began to observe and experiment with the plants (to learn or know how they grow and develop).
Neolithic period is named as revolution because this period changed the way of life of most of the communities. This first occurred in so-called "Fertile Crescent" or Mesopotamia (modern Iraq).
The Neolithic Revolution allowed people to live in permanent settlements.
Answer: Option B
Step-by-step explanation:
This phase 'Neolithic Revolution' witnessed the change in the behavior of the people, notably the development of habits like hunting and gathering of animals and fruits.Although it is a development of habits, people refer to it as a revolution because it changed the lifestyle of the communities.It dates back to prehistoric times which is said to have happened almost nine thousand years ago. Thereby concluding that, the Neolithic revolution allowed people to live in permanent settlements.Please help me out this kind of confused me thank you in advance!

A recipe for 8 apple dash cinnamon muffins calls for 1 cup of flour. The number of muffins that can be made varies directly with the amount of flour used. There are 1 and three fourths cups of flour available. How many muffins can be made?
Answer:
you can make 14 muffins
Step-by-step explanation:
To get this answer you first need to know that 1 cup makes 8 muffins. Next know that there's 1 3/4 cups of flour. Because you know that 1 cup makes 8 muffins you need to figure out how many muffins 3/4 a cup of flour can make. To do this you divide 8 by 4. Hence 8 divided by 4 is 2. So know you know that for every 1/4 cup you can make 2 muffins. Now since there's 3/4 cup of flour you then multiply 2 by 3 which is 6. Now you have to add 1 cup ( 8 muffins) to 3/4 cup ( 6 muffins ) of flour which then equals 14. You then get the answer , 1 3/4 cups of flour can make 14 muffins. Hope this helped ;)

Answer:
Farrah purchased the car in 2016 at the price of $22,440.
Step-by-step explanation:
Given:
Cost of the car in 2017 = $20,140
Depreciation in the cost after 2016 was = $2300
To find cost of the car in 2016.
Solution:
Let cost of the car in dollars in 2016 be = [tex]x[/tex]
Depreciation in value after a year was by = $2300
Thus, cost of car in dollars in 2017 will be = [tex]Original\ cost-Depreciation\ =x-2300[/tex]
Given cost of car in 2017 = $20,140
So, we have:
[tex]x-2300=20140[/tex]
Solving for [tex]x[/tex]
Adding 2300 both sides.
[tex]x-2300+2300=20140+2300[/tex]

Answer:
The price of each CD before tax was $15.30.
Step-by-step explanation:
Given:
Miguel bought 6 CDs that were each the same price.
Including sales tax, he paid a total of $99.60.
Each CD had a tax of $1.30.
Now, to find the price of each CD before tax:
So, to get the price of 1 CD including tax by using unitary method:
Total price of 6 CDs including tax = $99.60.
So, the price of 1 CD including the sales tax = $99.60 ÷ 6 = $16.60.
Thus, the price of each CD including tax = $16.60.
Tax on each CD = $1.30.
Now, by subtracting we get the price of each CD before tax:
[tex]\$16.60-\$1.30[/tex]
[tex]=\$15.30.[/tex]
Therefore, the price of each CD before tax was $15.30.
Angle X and angle Y are supplementary angles. Angle Y measures 33 degrees. what is the measure of angle X?
Answer: 147
Step-by-step explanation:
Supplementary: Angles that equal 180
180-33=147
147+33=180
The measure of supplement angle X is 147°.
Given that, angle X and angle Y are supplementary angles.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Here,
∠X+∠Y=180°
⇒ ∠X+33°=180°
⇒ ∠X=180°-33°
⇒ ∠X=147°
Hence, the measure of supplement angle X is 147°.

One number is 10 times as large as another and their difference is 81. Find the numbers.
Answer:
one number is 90 and the other one 9
Step-by-step explanation:
Let's refer to the larger number as "x", and the smaller as "y", so we can create equations with those unknowns and solve them algebraically.
Now let's write the first phrase we are given in mathematical form:
"One number is 10 times as large as another one"
Remember that our larger number is "x", so the first equation out of this phrase is:
x = 10 * y
Now for the second phrase:
"Their difference is 81"
Here we need to make the difference setting the larger number first (x), minus the smaller number (y), so as to get a positive difference of 81 units:
x - y =81
now we solve this system by substituting "x" in the second equation with "10 * y" according to what our first equation states:
10 y - y = 81
9 y = 81
y = 81/9
y = 9
and therefore now that we know the value of number y (9) we can go back to the first equation to find what number "x" is:
x = 10 * (9)
x = 90
Finally: x = 90, and y = 9

To determine:
We have to determine the missing side x.
Given:
Given angle = 29°Right angle = 90°The missing side x can be calculated by the formula:
sinФ = opposite ÷ hypotenuse
sin(29°) = x ÷ 3
0.4848 = x ÷ 3
x ÷ 3 = 0.4848
x = 0.4848 × 3
x = 1.45 cm
Hence, x = 1.45 cm is the length of missing side.
Question # 2 (Top Center)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 21°Right angle = 90°The missing side x can be calculated by the formula:
tanФ = opposite ÷ adjacent
tan(21°) = x ÷ 4
0.3838 = x ÷ 4
x ÷ 4 = 0.3838
x = 0.3838 × 3
x = 1.15 cm
Hence, x = 1.15 cm is the length of missing side.
Question # 3 (Top Right)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 66°Right angle = 90°The missing side x can be calculated by the formula:
cosФ = adjacent ÷ hypotenuse
cos(66°) = x ÷ 8
0.4067 = x ÷ 8
x ÷ 8 = 0.4067
x = 0.4067 × 8
x = 3.25 cm
Hence, x = 3.25 cm is the length of missing side.
Question # 4 (Bottom Right)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 29°Right angle = 90°The missing side x can be calculated by the formula:
cosФ = adjacent ÷ hypotenuse
cos(29°) = 3.7 ÷ x

x = 3.7 ÷ 0.8746
x = 4.23 cm
Hence, x = 4.23 cm is the length of missing side.
Question # 5 (Bottom Center)
Step-by-step Explanation:
To determine:
We have to determine the missing side x.
Given:
Given angle = 37°Right angle = 90°The missing side x can be calculated by the formula:
sinФ = opposite ÷ hypotenuse
sin(37°) = 5.1 ÷ x
0.6018 = 5.1 ÷ x
x = 5.1 ÷ 0.6018
x = 8.47 cm
Hence, x = 8.47 cm is the length of missing side.

A wholesaler buys pairs of sunglasses
for $5.50 each. He then marks up the
wholesale cost 80% to create a retail
price for his customers. Customers must
then pay an additional 7% tax on the
retail price. What is the total cost of a
pair of sunglasses to the wholesaler's
customers, including tax, rounded to
the nearest penny?
A customer will pay $10.59, including sales tax, for a pair of sunglasses.
Step-by-step explanation:
Given,
Purchase price of sunglasses = $5.50
Mark up = 80%
Amount of mark up = 80% of purchase price
Amount of mark up = [tex]\frac{80}{100}*5.50=0.80*5.50[/tex]
Amount of mark up = $4.40
Retail price = Purchase price+mark up
Retail price = 5.50+4.40 = $9.90
Sales tax = 7% of retail price
Sales tax = [tex]\frac{7}{100}*9.90=0.07*9.90[/tex]
Sales tax = $0.69
Total paid by customer = retail price + sales tax
Total paid by customer = 9.90 + 0.69 = $10.59
A customer will pay $10.59, including sales tax, for a pair of sunglasses.

Step-by-step explanation:
Let the total cost per year be y.
He spent a flat amount of $125 per year.
Then he spend an additional $35 per months. There are 12 months in a year so that's a total of 35*12=$420.
Add up the cost
y = 125 + 420 = $545

Answer:
[tex]\large \boxed{5.0 \, \% }[/tex]
Step-by-step explanation:
1. Calculate the amount of tax
Total cost = selling price + sales tax
Sales tax = total cost - selling price
Total cost = $651
-Selling price = - 620
Sales tax = $ 31
2. Calculate the percent tax
[tex]\text{\% Tax} = \dfrac{\text{\$31}}{\text{\$620}} \times 100 \, \% = \mathbf{5.0 \, \%}\\\\ \text{The sales tax percentage is $\large \boxed{\mathbf{5.0 \, \% }}$}[/tex]

Answer:
The correct answer is D. 69
Step-by-step explanation:
Let's recall that if an exterior angle has its vertex where two rays share an endpoint outside a circle, the measure of that exterior angle is found by dividing the difference between the measures of the intercepted arcs by two.
Therefore, we have:
x = (Measure of arch CD - Measure of arch BD)/2
Replacing with the real values:
x = (210 - 72)/2
x = 138/2 = 69°
The correct answer is D. 69
