On a number line, the coordinates of X, Y, Z. and Ware-7. -5.2, and 4, respectively. Find the lengths of the two segments below. Then tell whether they are congruent.
XY and ZW
The length of XY is (Type an integer or a decimal.)
The length of ZW is (Type an integer or a decimal)
Answer:
[tex]XY = 2[/tex]
[tex]ZW = 2[/tex]
XY and ZW are congruent
Step-by-step explanation:
Given
[tex]X = -7[/tex]
[tex]Y = -5[/tex]
[tex]Z = 2[/tex]
[tex]W = 4[/tex]
Distance XY is calculated as thus:
[tex]XY = |X - Y|[/tex]
[tex]XY = |-7 - (-5)|[/tex]
[tex]XY = |-7 + 5|[/tex]
[tex]XY = |-2|[/tex]
[tex]XY = 2[/tex]
Distance ZW is calculated as thus:
[tex]ZW = |Z - W|[/tex]
[tex]ZW = |2 - 4|[/tex]
[tex]ZW = |-2|[/tex]
[tex]ZW = 2[/tex]
[tex]XY = ZW = 2[/tex]
Hence:
XY and ZW are congruent

**Use 3.14 as the approximation for pi**
Answer:
79.74
Step-by-step explanation:
Multiply 6 by 12 and that by 2:
(6 × 12) × 2 - (6 × 6) = 72 × 2 - 36= 144 - 36 = 108
That will be the equation for the shaded area besides the circle now lets calculate the circle and take it away from the equation. the circle's diameter is 6 so the radius should be 3, then use:
3 × 3 × 3.14 = 9 × 3.14 = 28.26
Then do this:
108 - 28.26 = 79.74

Sam wants to earn at least a B in Math. He earned the following scores on tests so far: 82%, 70%, 72%, and 80%.
Which inequality below can be used to solve and determine what Sam needs to earn on the final exam in order to have at least a B-average in the class?
Answer:
Sam has to get at least a 96 in order to pass the class with a B.
Step-by-step explanation:
To find this you use mean in this format:
Test Scores + x (Exam Grade Needed) / # of Tests ≥ 80 (Which Is a B)
Substitute:
82 + 70 + 72 + 80 + x / 5 ≥ 80
Add:
304 + x / 5 ≥ 80
Get Rid of the Denominator (Multiply Both Sides By 5):
(5) 304 + x / 5 ≥ 80 (5)
Multiply:
304 + x ≥ 400
Isolate x (Subtract 304 From Both Sides):
x ≥ 96
This means that Sam has to get at least (Greater than or equal to) a 96 in order to pass with a B average.

Answer:
y = 88
Step-by-step explanation:
Don't worry about the other stuff, just worry about what's in the triangle that has Y.
53°, 39°, and y°
the sum should be equal to 180 so add 53 adn 39 and subtract it from 180.
180 - (53 + 39) = y
180 - 92 = y
88 = y

Step-by-step explanation:
A line passes through the point (-9,1) and has a slope of -2/3
Answer:
y - 1 = (-2/3)(x + 9)
Step-by-step explanation:
Here you are given a point on a line and the slope of the line. You'll need to apply the "point-slope" formula
y - k = m(x - h) (Memorize this)
Then m = slope = -2/3, h = -9 and k = 1.
Making the appropriate substitutions, we get:
y - 1 = (-2/3)(x + 9)

What is the value of x in the figure below? In this diagram, ΔABD ~ ΔCAD.
Answer:
D
Step-by-step explanation:
The triangles CDA and ADB are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{AD}[/tex] = [tex]\frac{DA}{DB}[/tex] , substitute values
[tex]\frac{13}{x}[/tex] = [tex]\frac{x}{3}[/tex] ( cross- multiply )
x² = 39 ( take square root of both sides )
x = [tex]\sqrt{39}[/tex] → D
Answer:
D is the answer

Average movie in the Uruled States gerveral . Cost tickets in Japan plus two tickets in Switzerlandtickets in Switzerland plus two tickets in Japan would cost \$/5.27 . How much does an average movie ticket cost in each of these countries in Japan the average costis Switzerland the average cost is $
Answer:
The average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75
Step-by-step explanation:
The question seems to be incomplete. Here is a similar question and the solution:
Average movie prices in the United States are, in general, lower than in other countries. It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $76.97. How much does an average movie ticket cost in each of these countries?
Step-by-step explanation:
Let the cost of tickets in Japan be $x and the cost of tickets in Switzerland be $y.
From the question,
It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. That is
3x + 2y = 81.08 ...... (1)
Also from the question,
Three tickets in Switzerland plus two tickets in Japan would cost $76.97. That is
2x + 3y = 76.97 ...... (2)
Multiply equation (1) by 2, so that we get
6x + 4y = 162.16 ...... (3)
and multiply equation (2) by 3, so that we get
6x + 9y = 230.91 ...... (4)
Now, Subtract equation (3) from equation (4), we get
5y = 68.75
y = 68.75/5
y = 13.75
Put the value of y into equation (1) to determine x
3x + 2y = 81.08
3x + 2(13.75) = 81.08
3x + 27.5 = 81.08
3x = 81.08 - 27.5
3x = 53.58
x = 53.58/3
x = 17.86
∴ x = 17.86 and y =13.75
Hence, the average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75.
A binder at the store costs $4.87. A pack of pens at the same store costs $2.94. You pay for both the binder and pack of pens with a $20 bill
How much change do you receive?
Answer:
How much change you receive is $12.19
Step-by-step explanation:
$20 - $4.87 (price of a binder) - $2.94 (price of pack of pens) = ?
$4.87 + $2.94 = $7.81
$20 - $7.81 = $12.19
