Answers
Answer:
A. She can rotate AABC 90° and then compare the angles and sides.
She will see that the triangles are congruent by the Angle Side Angle theorem.
Step-by-step explanation:
Congruent is a term that implies that a thing is identical to another (having the same shape and size). For congruent triangles, they have the same shape and size; they can be tilted or rotated to be at different angles but they have the same shape and size irrespective.
The following information were given:
D - 30°, 3 cm, 65°
B - 30°, 3 cm, 65°
From this information, we can conclude that the triangles are congruent based on the Angle Side Angle theorem. However, because the diagram was not included, we cannot conclusively say which is the more accurate answer between Options A & B.

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
Use the equation below to find v, if u=17, a=4, and t=8. 4=u+at
Answers
Answer:
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
Step-by-step explanation:
The given equation is:
4 = u + at
where u = 17, a = 4, and t = 8.
Substituting the given values, we get:
4 = 17 + 4(8)
Simplifying the right-hand side:
4 = 17 + 32
Combining like terms:
4 = 49
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Angle 5 and Angle 7
Angle 1 and Angle 10
Angle 14 and Angle 16
Angle 7 and Angle 11
Answers
The two angles must be supplementary with angles 6 will be angle 5 and 7.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
⇒ 4 lines intersect to form 16 angles.
And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,
Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.
So, The supplementary angles to angle 6 are angle 5 and angle 7.
Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

A triangular prism is attached to a rectangular prism as shown below.
If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the total surface area of the EXTERIOR FACES of the figure?
(Answer choices in picture!!) (I WILL GIVE BRAINLIEST)
Answers
Surface area of the triangular prism:
The triangular prism has two triangular faces and three rectangular faces.
The triangular faces have base (x) of 5 inches and height (y) of 20 inches. The surface area of each triangular face is (1/2) * base * height = (1/2) * 5 * 20 = 50 square inches.
The rectangular faces have dimensions (w, y, and z) of 8 inches, 20 inches, and 11.3 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the three rectangular faces, we get: 2 * (w * y) + 2 * (w * z) + 2 * (y * z) = 2 * (8 * 20) + 2 * (8 * 11.3) + 2 * (20 * 11.3) = 320 + 180.8 + 452 = 952.8 square inches.
Surface area of the rectangular prism:
The rectangular prism has six rectangular faces.
The dimensions of the rectangular prism are (w, x, and y) of 8 inches, 5 inches, and 20 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the six rectangular faces, we get: 2 * (w * x) + 2 * (w * y) + 2 * (x * y) = 2 * (8 * 5) + 2 * (8 * 20) + 2 * (5 * 20) = 80 + 320 + 200 = 600 square inches.
Total surface area of the exterior faces:
To find the total surface area of the exterior faces, we add the surface areas of the triangular prism and the rectangular prism: 50 + 952.8 + 600 = 1,602.8 square inches.
Therefore, the total surface area of the exterior faces of the figure is approximately 1,602.8 square inches. However, none of the given answer choices match this value. Please recheck the given dimensions or options provided.

Answer: The area of the given shape is 9.734 meter square
Step-by-step explanation:
The given shape is a square with 4 sides of equal dimensions "a",
Area of Square = Square of its side "a"
Here, a = Hypotenuse of the inner triangle
Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.
Step 2: By using Pythagoras theorem,
Square of the base + Square of the height = square of the Hypotenuse
(2.4)^2 + (2.0)^2 = 9.76
Therefore the value of the hypotenuse = 3.12m
The area of the square = 9.734 meter square.

Math problem: You are enlarging a photo on your computer screen. The photo starts at 3 centimeters wide. Each time you enlarge the photo, its width is doubled. You enlarge the photo four times. What is the final width of the photo on your screen?
Answers
Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6
second enlargement you get 12
third enlargement you get 24
fourth enlargement you get 48
if you times 3 by 4 you are not doubling the width each time you enlarge the photo
so it is easier to double it each time you enlarge it
work:
since the photo starts at 3 cm wide and the width gets doubled each time for four times, youd have to do 3^4.

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!
