According to the Symmetric Property of Equality, if AB = CD then CD = AB.
According to the question,
We have the following information:
CD = AB then AB = ?
Now, in order to fill the given blank, we have to use the symmetric property of equality. According to the symmetric property of equality, there is no difference in the final result of an expression if we change the sides of the expression.
For example, if 2 = a then we can also say that a = 2.
So, when CD=AB then we can clearly state that AB = CD.
Hence, according to the Symmetric Property of Equality, if AB = CD then CD = AB.

THROUGH (-3,-1) perp to y=-1/2x+5
ANSWER IT
The equation of the perpendicular line that passes through the point (- 3, - 1) is y = 2 · x + 5.
What is the equation of the line perpendicular to another line?
In this question we must determine the equation of a line that is perpendicular to another line and pass through a given point. Mathematically speaking, lines are represented by the following equation:
y = m · x + b
Where:
m - Slopeb - y-Interceptx - Independent variabley - Dependent variableAnd the slopes of two lines perpendicular to each other satisfy the following relationship:
m · m' = - 1
Where:
m - Slope of the original line.m' - Slope of the perpendicular line.First, determine the slope of the perpendicular line by means of the slope relationship:
m = - 1 / 2
m' = - 1 / m
m' = - 1 / (- 1 / 2)
m' = 2
Second, find the intercept of the perpendicular line by the equation of the line:
b = y - m · x
b = - 1 - 2 · (- 3)
b = - 1 + 6
b = 5
Third, write the equation of resulting line:

Find the measures of all three interior angles and exterior angles. ILL GIVE BRAINLIEST
The interior angles are 43°, 43° and 94°. and exterior angle is 86°
Let the interior angles are ∠A, ∠B and ∠C.
From the question, we have
∠A = (5x-12)°
exterior angle = (8x-2)°
As the sides are equal
∠A =∠B = (5x-12)°
∠C = 180°-(8x-2)°
=182°-8x
Sum of interior angles of a triangle is equals to 180 degree.
∠A + ∠B + ∠C = 180°
(5x-12)°+(5x-12)°+182°-8x = 180°
2x+158° = 180°
x = 11°
Interior angles,
∠A =∠B = (5x-12)°
= (5*11-12)°
=43°
∠C =182°-8x
=182°-8*11
=94°
exterior angle = (8x-2)°

In the given question we have to graph JKL with vertices J(1, 3), K(5, 0), and L(7, 4) and its image after the glide reflection with a translation along <0,-3> and areflection in the y-axis.
The given vertices are J(1, 3), K(5, 0), and L(7, 4).
Firstly translation along (0,-3).

When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake?
The option that explains Sarita's mistake is Sarita’s solution is correct. She made an error in her verification.
What was Sarita's mistake?The given equation is: 5(x - 3) + 7(x + 4) = 73
In order to determine the value of x, take the following steps:
1. Apply the Distributive property:
5x - 15 + 7x + 28 = 73
2. Add similar terms together:
12x + 13 = 73
3. Combine similar terms:
12x = 73 - 13
4. Add similar terms
12x = 60
5. Divide both sides of the equation by 12
x = 60 / 12
x = 5
In order to verify the answer, substitute for x in the given equation :
5(5 - 3) + 7(5 + 4) = 73
5(2) + 7(9) = 73

If you select two different women at random, what’s the probability that:
A. At least one experienced IPV?
B. At least one did not experience IPV?
The probability of selecting at least one experienced IPV is 0.598 and at least one did not experience IPV is 0.866.
In the given question we have to find the probability of selecting at least one experienced IPV and at least one did not experience IPV
From the given table
Probability of experiencing IPV
P(Experienced IPV) = 366 / 1000 = 0.366
Probability of not experiencing IPV
Q(Not-experienced IPV) = 634 / 1000 = 0.634
Now when n samples are chosen from the population, the binomial probabilty distribution follows (P + Q)^n.
Here, n = 2,
So, (p +q)^2 = p^2 + 2pq + q^2
p^2 = Both experienced IPV
2pq = One has experienced IPV and other hasn’t
q^2 = None have experienced IPV.
A. Finding the probability of at least one experienced IPV.
P(At least one has experienced IPV) = P^2 + 2PQ
= (0.366)^2 + 2(0.366)(0.634)
=0.1339+0.4641
= 0.598
B. Finding the probability of at least one did not experienced IPV.
Q(At least one did not experienced IPV) = Q^2 + 2PQ
= (0.634)^2 + 2(0.366)(0.634)
=0.4019+0.4641

D. Is there a proportional relationship between time and costs of the gym membership plan? Explain how you know.
Answer:
A) $75
B) y = 30x + 15
C) (24, 735) **graph below
D) Yes, there is a proportional relationship
Step-by-step explanation:
We can represent this relationship with an equation.
y = 30x + 15
where x would represent the months and y would be the total cost. The 15 would be the initial fee, which only occurs once.
A) Using the relationship [tex]y = 30x + 15[/tex], we can substitute 2 for x, since that would represent the months.
[tex]y = 30x + 15\\y = 30(2) + 15\\y = 75[/tex]
It would be 75 dollars.
B) The total cost for x months would just be the relationship
[tex]y = 30x + 15[/tex]
C) 2 years would represent 24 months. The screen shot below would represent the relationship. The y axis would be the total cost in dollars and the x axis would be the months. (24, 735)
D) Yes, there is a proportional relationship because as the time (months) progress or increases so does the price (dollars). The graph is linear too, which means it increases.
Water i draining from a conical tank at the rate of 2 m3/min. The tank i 16 meter high and the top radiu i 4 meter. How fat i the water level falling when the water’ level i 12 meter high?
Answer:
7.07 cm/min
Step-by-step explanation:
You want the rate of change of water level in a conical tank 16 m high with radius 4 m when the level is 12 m and the water is draining at 2 m³/min.
Surface areaThe level of water in the tank is 12/16 = 3/4 of the height of the tank, so the radius of its surface is (3/4)(4 m) = 3 m. The surface area is ...
A = πr²
A = π(3 m)² = 9π m² ≈ 28.3 m²
Level changeThe rate of change of level is the rate of change of volume divided by the surface area:
V'/A = (-2 m³/min)/(9π m²) = -2/(9π) m/min ≈ -0.07074 m/min
The water level is falling at about 7.07 cm/min.
9. Higher Order Thinking The length of a postage stamp is
millimeters longer than its width. The perimeter of the
stamp is 124 millimeters.
a. Write the equation that represents the situation.
b. What is the width of the postage stamp?
c. What is the length of the postage stamp?
The equation that represents the situation is 2(x+17/4+x) = 249/2 where x is the width, the width of the postage stamp is 29 millimeters and its length is 33.25 millimeters.
According to the question,
We have the following information:
The length of a postage stamp is [tex]4\frac{1}{4}[/tex] millimeters longer than its width. The perimeter of the stamp is [tex]124\frac{1}{2}[/tex] millimeters.
Now, let's take the width of the stamp to be x millimeters.
Length of the stamp = x + 17/4
(We have the converted the fractions from the mixed fraction.)
Now, we have the following expression because the stamp is in the shape of a rectangle:
2(length+width) = 249/2
a) 2(x+17/4+x) = 249/2
b) 2(2x+17/4) = 249/2
Dividing by 2 on both sides of the equation:
2x+17/4 = 249/2*2
2x+17/4 = 249/4
Subtracting 17/4 from both sides of the equation:
2x = 249/4 - 17/4
2x = 232/4
Dividing by 2 on both sides:
x = 232/(4*2)
x = 116/4
x = 29 millimeters
c) Length of the stamp = 29+17/4
Length = (116+17)/4
Length = 133/4
Length = 33.25 millimeters
Hence, the equation that represents the situation is 2(x+17/4+x) = 249/2 where x is the width, the width of the postage stamp is 29 millimeters and its length is 33.25 millimeters.
