You would see if they are similar if they have similar sides. so if there is an equal ratio, to both, they are similar. Sometimes they may not look similar until you rotate them. So for the following, you can see that if E were on the bottom, it would look like the triangle with N and M on the bottom you can ensure this to look at the ratios of each side. To find the scale factor, it depends on which way you are going. are you going from GEF to MNL or MNL to GEF? To me, it doesn't look like there is a scale factor, but I could be wrong.

The length of the sides of ΔABC are; AB = 2√5, BC = √13, and AC = √17
The length of the sides of ΔDEF are; DE = 2√5, EF = √13, and DF = √17
By the SSS Congruence Theorem, ΔABC ≅ ΔDEF
How to prove triangle congruency postulate?We are given the coordinates of Triangles ABC and DEF as;
A(5, 3), B(7, 7), C(9, 4)
D(-8, 6), E(-12, 8), F(-9, 10)
The formula for distance between two coordinates is;
Distance = √[(y₂ - y₁)² + (x₂ - x₁)²]
Thus;
AB = √[(7 - 3)² + (7 - 5)²]
AB = √20
AB = 2√5
Similarly;
BC = √[(4 - 7)² + (9 - 7)²]
BC = √13
AC = √[(4 - 3)² + (9 - 5)²]
AC = √17
Likewise;
DE = √[(8 - 6)² + (-12 + 8)²]
DE = √20
DE = 2√5
Similarly;
EF = √[(10 - 8)² + (-9 + 12)²]
EF = √13
DF = √[(10 - 6)² + (-9 + 8)²]
DF = √17
Since the corresponding sides of the two triangles are equal and as such they can be said to congruent by SSS Congruency.

What is right-angled triangle?
Triangle that has one angle 90 degree is called right-angled. In case of a right triangle the square of the largest side length is equal of the sum of the square of the other two side length.
what is the value of c in the above formula?
SA triangle has three side length 11-unit, 60 unit and 61 unit respectively.
The triangle is verified as a right-angled triangle by Pythagorean theorem.
And as the properties of a Pythagorean theorem the sum of the square of two side length is equal to the square of the largest side length.
if we say, one side length, a = 11 unit
second side length, b = 60 unit
the largest side length, c
now we will check,
√(11²+60²) = c² =√3721 = 61
the value of c = 61 unit.
hence, the SA is right-angled triangle.

4x-4×8=
4x-32
4x-10-32=
-40 -32= -72
Step-by-step explanation:
I think this is right sorry if I'm wrong
Answer:
We need to keep y on the left side only.
so we distribute the 4x to the right side.
that means:
4x - 4y = 8
-4x -4x
-4y = 8 - 4x
Now we divide by -4 on both sides
y = 8 - 4x/-4
-2 + x is y
Now for number 2:
Let's use -10 for x.
-2 -10 = -12

In regression analysis, which of the following is not a required assumption about the error term e?
Answer
O The expected value of the error term is zero.
O The variance of the error term is the same for all values of x.
O The values of the error term are independent.
O All are required assumptions about the error term.
All are required assumptions about the error term.
In regression analysis, there are several assumptions that need to be met regarding the error term :
The expected value of the error term is zero: It is the assumption that the mean of the error term is zero, which means that on average, the predicted values of the dependent variable will be equal to the true values of the dependent variable.The variance of the error term is the same for all values of x: It is the assumption that the spread of the error term is constant across all levels of the independent variable.The values of the error term are independent: It is the assumption that there is no relationship between the error term at different levels of the independent variable.All three assumptions are required for valid regression analysis, and any violation of these assumptions can lead to biased or inefficient estimates of the model parameters.To know more about error terms click below:

Mr. Gutierrez had $100 to purchase candy for his students that completed their work. He
bought 8 bags of jolly ranchers and 25 bags of assorted chocolate. Each bag of jolly
ranchers cost $3.25, and each bag of assorted chocolate cost $2.10. How much money
did Mr. Gutierrez have left over after these purchases?
Answer:
$21.50
Step-by-step explanation:
Mr. Gutierrez had $100 to purchase candy for his students that completed their work.
He bought 8 bags of jolly ranchers
Each bag of jolly ranchers cost $3.25.
Hence, the cost of 8 bags of jolly ranchers = 8 × $3.25
= $26
He also bought 25 bags of assorted chocolate and each bag of assorted chocolate cost $2.10.
Hence, the cost of 25 bags of assorted chocolates = 25 × $2.10
= $52.5
Therefore, the amount of money Mr. Gutierrez has left over after these purchases is calculated as:
Total amount - Sum of ( Cost of 8 bags of jolly ranchers + 25 bags of assorted chocolates)
= $100 - ( $26 + $52.5)
= $100 - $78.50
= $21.50

27x + 126 = 180 ( subtract 126 from both sides )
27x = 54 ( divide both sides by 27 )
x = 2

Priscilla has 4.3*10^8 strands of hair on her head. Diego has 8.7*10^5 strands of hair on his head. How many more strands of hair does Priscilla have than Diego? Express your answer in scientific notation.
====================================================
Work Shown:
4.3*10^8 = 4.3 * 10^(3+5)
4.3*10^8 = 4.3 * 10^3*10^5
4.3*10^8 = 4.3*1000*10^5
4.3*10^8 = 4300*10^5
Priscilla has 4300*10^5 strands of hair while Diego has 8.7 * 10^5 strands. Subtract the values out front: 4300-8.7 = 4291.3
Then tack on the "*10^5" portion to get 4291.3*10^5
The difference in the number of strands is 4291.3*10^5
Convert this to scientific notation to get the final answer.
4291.3*10^5 = (4291.3)*10^5
4291.3*10^5 = (4.2913 * 1000)*10^5
4291.3*10^5 = 4.2913 * 1000*10^5
4291.3*10^5 = 4.2913 * 10^3*10^5
4291.3*10^5 = 4.2913 * 10^(3+5)
4291.3*10^5 = 4.2913 * 10^8
Note: The number 4.2913 * 10^8 expands out to 429,130,000 which is a little over 429 million.
A line intersects the points (0,-4) and (1,2) what is the slope intercept equation for this line?
Answer:
[tex]y=6x-4[/tex]
Step-by-step explanation:
First we have to know how to write a equation in Slope-Intercept Form!
Slope-Intercept Form: [tex]y=mx+b[/tex]
where y = y axis, m = slope, x = x intercept and b = y-intercept
Now start by solving the slope
To find the Slope, you must find two points
Two points will be: [tex](0,-4)[/tex] and [tex](1,2)[/tex]
Then use the Slope-Formula to identify the slope
[tex]m=slope[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2--4}{1-0}[/tex]
[tex]m=\frac{6}{1}[/tex]
[tex]m=6[/tex]
The Slope is 6
The y-intercept is already given by the point (0, -4)
Note: (this goes to this situation because the point has a 0 of x intercept)

At the beginning of the year, a blogger has 150 subscribers. Since then, the number of subscribers to her blog has been doubling every 6 months, thanks to some successful appearances on television.
1) by what factor is the number of subscribers increasing every month?
2) write an equation that represents the number of subscribers (s) in terms of m months since the beginning of the year( when she had 150 subscribers)
The number of subscriber is increasing by factor 1,12 every month. The number of subscribers m months since the beginning of the year can expressed by the growth model equation S(m) = 150 . e^(0.12m)
The problem can be solved using exponential growth model.
1) The relation between growth rate and doubling time is given by:
doubling time = 70 / growth rate
In this case, doubling time = 6 months.
Hence,
growth rate = 70/6 = 11.67% = 0.1167 ≈ 0.12
Growth factor is defined as:
Growth factor = 1 + growth rate
= 1 + 0.12 = 1,12
2) The growth model of the number of subscribers is given by:
S(m) = So . e^(r.m)
Where:
S(m) = number of subscriber after m months
So= initial number of subscriber
r = growth rate
t = time period
Substitute So = 150 and r = 0.12
S(m) = 150 . e^(0.12m)

In this situation, 20 feet is the radius of the circle that is sprayed.
Use the area formula, A = [tex]\pi[/tex]r²
Plug in 20 as the radius and solve:
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](20)²
A = 400[tex]\pi[/tex]

Step-by-step explanation:
The statement says that the angles GIH and QRS must be the same measurement. To show that on diagrams, we use markings : if angles have the same markings, then it means they have the same measurement.
That way, we just need to see which diagram has the right measurements.
First, the angles GIH and QRS are the angles we see named by the letter in the center : then GIH and QRS.
So it must be the angles with letters of I and R that have the same markings.
A : doesn't work for I and R
B : doesn't work for I and R
