Answer:
2) tri ABC is congreunt to tri DEF
Step-by-step explanation:
you would have to make sure you name the traingles in a specific order so the congruent angles in both triangles are listed in the same order :))
The option that best describes the relationship between AABC and ADEF is AABC ~ ADEF, the correct option is B.
What are similar triangles?
All similar triangles are triangles that share these two features presented as follows;
1. Congruent angle measures.
2. Proportional side lengths.
We are given that;
AB is similar to DE: BC is similar to EF; AC is similar to DF; ZA is similar to ZD; ZB is similar to ZE; ZC is similar to ZF.
Now,
The relationship between two similar triangles is that their corresponding angles are equal and their corresponding sides are proportional1. This means that if AABC and ADEF are similar, then:
∠A = ∠D
∠B = ∠E
∠C = ∠F
AB/DE = BC/EF = AC/DF
To describe this relationship, we can use a notation that shows which angles and sides correspond to each other. For example, we can write:
AABC ~ ADEF
This means that triangle ABC is similar to triangle DEF and the order of the letters shows how they match up. The first letter of each triangle corresponds to the first angle, the second letter corresponds to the second angle, and so on.
Therefore, by similar triangle properties the answer will be AABC ~ ADEF.

Step-by-step explanation:
Max puts a stopper in the bathtub and turns on the faucet at t=0. After 5 minutes, there are 11 gallons of water in the tub and after 10 minutes, there are 22 gallons in the tub. Write an equation that relates the number of gallons, g, to the time, t. Does the relationship represent a linear function? Justify your response.
Answer:
y = 2.2x
Yes, it represents a linear function
Step-by-step explanation:
Given that :
Stopper applied at t = 0
At t = 5 minutes ; water in tub = 11 gallons
At t = 10 minutes ; water in tub = 22 gallons
General form of a linear function :
y = mx + c
Where c = intercept ; m = Slope ; y and x are dependent and independent variables respectively
The intercept = gallon of water at t = 0 ; this is not given and will be taken as 0
Slope = change in y / charge in x
Slope = (22 - 11) / (10 - 5)
Slope = 11 / 5
Slope = 2.2
Hence ;
y = 2.2x + 0
y = 2.2x
Yes, it represents a linear function
What is the slope of a line perpendicular to the line whose equation is
4x – 3y = –27. Fully reduce your answer.
Answer:
-3/4
Step-by-step explanation:
We can rearrange the equation to get 3y = 4x + 27. Then we can find the slope intercept form: y = 4x/3 +9. You find the perpendicular slope by solving for the opposite and reciprocal of the current slope 4/3. So we would get -4/3, and then -3/4.

the accompanying histogram shows the heights of the students in kyra's health class. what is the total number of students in the class
The total number of students is equal to 16 students.
We are given that the accompanying histogram shows the heights of the students in Kyra's health class.
A histogram is a graph that shows the frequency of numerical data with the help of rectangular bars.
The height of a rectangle (the vertical axis) represents the distribution frequency of a variable ( amount).
We need to calculate the total number of students in the class.
We can see that for the first interval, the frequency is given as:
F1 = 2
For the 2nd interval, the frequency is given as:
F2 = 4
For the 3rd interval, the frequency is given as:
F3 = 5
For the 4th interval, the frequency is given as:
F4 = 4
For the 5th interval, the frequency is given as:
F5 = 1
The total students = 2 + 4 + 5 + 4 + 1
Total number of students = 16 students.
Therefore, the total number of students is equal to 16 students.

by looking at the graph given we can see that:
The graph is decreasing in (-∞, -5]The graph is increasing in [5, ∞)And the function is never constant.
How to determine in which intervals the function increases, decreases or is constant?
Here our function is:
f(x) = √(x^2 - 25)
And we have a graph of it.
First, remember that the argument of a square root needs to be zero or larger, so the interval (-5, 5) is not in the domain of our function.
We also can see that this is a square root, so there are no interval where the function is constant.
Finally, by looking at the graph given we can see that:
