Answer:
Step-by-step explanation:
It all depends on how many people are in your class.
To calculate probability
Determine a single event with a single outcome.
Identify the total number of outcomes that can occur.
Divide the number of events by the number of possible outcomes.
To determine the probability, Use the formula
What is the formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
P(A | B) = P(A∩B) / P(B)

what is the perimeter of the triangle. i do not know how to start this problem. any help will be greatly appreciated :))
Given:
Point F,G,H are midpoints of the sides of the triangle CDE.
[tex]FG=9,GH=7,CD=24[/tex]
To find:
The perimeter of the triangle CDE.
Solution:
According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.
FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get
[tex]\dfrac{1}{2}DE=FG[/tex]
[tex]DE=2(FG)[/tex]
[tex]DE=2(9)[/tex]
[tex]DE=18[/tex]
GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get
[tex]\dfrac{1}{2}CE=GH[/tex]
[tex]CE=2(GH)[/tex]
[tex]CE=2(7)[/tex]
[tex]CE=14[/tex]
Now, the perimeter of the triangle CDE is:
[tex]Perimeter=CD+DE+CE[/tex]
[tex]Perimeter=24+18+14[/tex]
[tex]Perimeter=56[/tex]
Therefore, the perimeter of the triangle CDE is 56 units.

Which of the following would NOT work to make a triangle with the two slide lengths of 2 and 6
A.6
B.5
C.7
D.4
Given:
The two sides of a triangle are 2 and 6.
To find:
The side length that would NOT work to make a triangle with the two slide lengths of 2 and 6.
Solution:
For a triangle, the sum of two smaller sides must be greater than the largest side.
Let x be the third side.
Case 1: x is the largest side, then
[tex]2+6>x[/tex]
[tex]8>x[/tex] ...(i)
Case 2: x is not the largest side, then
[tex]2+x>6[/tex]
[tex]x>6-2[/tex]
[tex]x>4[/tex] ...(ii)
From (i) and (ii), we get
[tex]4<x<8[/tex]
Here, 4 and 8 are not included.
6, 5, 7 are included in the above interval, but 4 is not included in the above interval. It means 4 would NOT work to make a triangle with the two slide lengths of 2 and 6.
Therefore, the correct option is D.
BRAINLIEST please please helpp!! Brainliest for correct answer!!! Use the triangle formed by the vertices L(-3, 4), A(0, 5), and D(2, 1). L'A'D ' is a triangle formed by using the transformation rule (x, y) -> (-x, y).
A. what type of transformation is LAD -> L'A'D'?
B. Are LAD and L'A'D' congruent or similar?
Answer:A: reflection. B: congruent
Step-by-step explanation:(x, y) -> (-x, y) means that the triangle reflected from the (x, y) part of the graph to the (-x, y) part of the graph.

What is the surface area of the rectangular prism shown above?
Answer:
The surface area of the rectangular prism is [tex]160in^2[/tex].
Step-by-step explanation:
The surface area of a 3-dimensional shape is found by adding the area of each side of the shape together. In this case, the areas of each side of the rectangular prism are 20 in, 20 in, 50 in, 50 in, 10 in, and 10 in. Find the surface area by adding each area together and you'll get [tex](50*2)+(20*2)+(10*2)=100+40+20=160in^2[/tex].
Answer:
The answer would be 160 .

We are going to fence in a rectangular field that encloses 75 ft2. Determine the dimensions of the field that will require the least amount of fencing material to be used.
Answer:
For width W and length L, we have:
W = L = √(75ft^2) = 8.66ft
Step-by-step explanation:
For a rectangle of length L and width W, the area is:
A = L*W
and the perimeter is:
P = 2*L + 2*W
First, we know that the area of our rectangle is:
A = 75ft^2 = L*W
And we want to minimize the perimeter of our rectangle, then we need to minimize:
P = 2*L + 2*W
From the equation:
75ft^2 = L*W
We can isolate one of the variables, let's isolate L
L = (75ft^2)/W
We could replace this in the perimeter equation:
P(W) = 2*( (75ft^2)/W) + 2*W
P(W) = (150 ft^2)/W + 2*W
To find the minimum of the perimeter we need to look at the zero of the first derivative of P(W).
P'(W) = dP(W)/dW = -(150ft^2)/W^2 + 2
Now we need to find the value of W such that:
P'(W) = 0
0 = -(150ft^2)/W^2 + 2
(150 ft^2)/W^2 = 2
(150ft^2) = 2*W^2
(150ft^2)/2 = W^2
75 ft^2 = W^2
√(75ft^2) = W = 8.66ft
And remember that:
L = (75ft^2)/W
replacing with W = √(75ft^2)
L = (75ft^2)/√(75ft^2) = √(75ft^2)
Then:
W = L = √(75ft^2) = 8.66ft

rounded off = 17 games
A triangular pyramid has a volume of 48 in3. The base edge is 9 in and the base height is 4 in. Find the height of the pyramid.
Answer:
8 in
Step-by-step explanation:
First of all we have to find the area of the base triangle.
For do this we can use this formula:
A = (base edge x base height)/2
A = (9 x 4)/2 = 18 in^2
The formula for find the volume of a pyramid is:
V= Base area x height)/3
So the height can be find in this way
3 x V = base area x height
height = (3 x V)/base area
height = (3 x 48)/18 = 8 in
Answer:
pretty sure it is 8in I think
Andy constructed a triangle. Angle 1 and 2 are the same size and angle 3 has a measurement of 100 degrees. What is the measurement of angle 1 and angle 2?
a , 30
b 40
c 60
d 90
Answer:
Angle 1: 40
Angle 2: 40
Step-by-step explanation:
A triangle's angles will ALWAYS add up to 180 degrees total, therefore you can subtract 100 from 180 to find what the measure of A and B are combined.
180 - 100 = 80
So now we know Angles A and B add to 80 degrees, but individually, each is half of that, so both are 40 degrees.
what is the value of X
Answer: It is 250
Step-by-step explanation: you would add 40 and 70 together which is 110 and then you would subtract 360 from 110 and you answer would be 250.
Answer:
x = 125
Step-by-step explanation:
Kindly check the image below
The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )
According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2
( Note that we are not given the direct intercepted arcs of x. We are given the intercepted arcs of x's supplementary angle )
That being said we need to find x's supplement in order to find x
Using the image below as a reference
x's supplement = [tex]\frac{70+40}{2}[/tex]
[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]
So x's supplement = 55
Now to find x
Remember that supplementary angles have a sum of 180°
That being said we can find the missing angle (x) by subtracting the given angle (55) from 180
so x = 180 - 55
180 - 55 = 125
Hence x = 125
HELP WITH THIS PLEASEEEE
Answer:
1) G
2) B
3) I
4) H
Step-by-step explanation:
Perimeter of a triangle formula:
P = a + b + c
1)
P = x + 6 + 3x + 2 + 2x + 4
P = 6x + 12
2)
P = 6x + 4 + 7x + 1 + 5x + 7
P = 18x + 12
3)
P = 4x - 3 + 3x + 5x - 6
P = 12x - 9
4)
P = 6x - 8 + 3x + 7 + 5x - 3
P = 14x - 4

Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (To the nearest whole inch)
Answer:
The listed size is 32 inches
Step-by-step explanation:
Given
See attachment for television
Required
The listed size
The listed size is calculated by the diagonal of the television.
This is calculated as using Pythagoras theorem as follows:
[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]
Where:
[tex]Length1 =28in[/tex]
[tex]Length2 =15.7in[/tex]
So, we have:
[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]
[tex]Diagonal^2 = 784 + 246.49[/tex]
[tex]Diagonal^2 = 1030.49[/tex]
Take positive square roots of both sides
[tex]Diagonal = \sqrt{1030.49[/tex]
[tex]Diagonal = 32[/tex] --- approximated
Hence, the listed size is 32 inches
