What is Exterior angles theorem?
Answer:
Exterior Angle Theorem
Step-by-step explanation:
An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side. The Exterior Angle Theorem states that An exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Answer:
30.8, 37
Step-by-step explanation:
First, we know that the angles in a triangle add up to 180, so 180-75-48= m∠G=57°. Then, using sohcahtoa, we have tan(G) = DF/FG = DF/20. tan(G) ≈ 1.54, so 20(1.54)=DF≈ 30.8
Next, using sohcahtoa, we have cos(G) = FG/DG = 20/DG. cos(G)≈0.54, and 20/0.54=DG ≈ 37

Consider the intersecting lines shown. Which of the following statements is true?
Question 10 options:
A)
∠y ≅ ∠z
B)
∠x ≅ ∠y
C)
m∠x + m∠y = 180°
D)
m∠x + m∠y = 90°
Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.
3 lemons cost $0.99. At this rate, how much would 8 lemons cost?
Step-by-step explanation:
3 lemons = $0.99
=> 8 lemons = $0.99 * (8/3) = $2.64.
8 lemons cost $2.64.
Answer:
2.64$ for 8 lemons.
Step-by-step explanation:
3 lemons = 0.99$
1 lemon = 0.99/3
= 0.33
Cost for 8 lemons = 0.33 x 8
= 2.64$

Rachel drew the two graphs below. Graph R On a coordinate plane, a line goes through points (0, 0) and (2, 1). Graph S On a coordinate plane, a line goes through points (0, 0) and (1, 2). Rachel says that Graph R has a greater constant of variation than Graph S. Which statement explains whether Rachel is correct? Rachel is correct; Graph S is nonproportional. Rachel is correct; Graph R goes farther along the x-axis. Rachel is not correct; both graphs go through the origin and have the same constant of variation. Rachel is not correct; Graph S is steeper than Graph R.

slope = 4/1 or 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Use the slope formula. change in y/change in x. The change in y is 4 because if your subtract the y coordinate 4 from the y coordinate 8, you get 4. The change in x is 1 because if you subtract the x coordinate 2 from the x coordinate 3, you get 1. 4 (change in y)/1 (change in x) is 4. Hope this helps!

The weight of body is 420N. calculate its mass.
Answer:
mass = 42 kg
Step-by-step explanation:
We know that we have the formula that
W = m * g
Then
given
weight (w) = 420
g = 10 m/s²
then
W = m* g
420 = m * 10
m = 420/10
m = 42 kg
Hope it helps :)
Answer:
Step-by-step explanation: weight = 420N
mass= ?
we know,
weight = mass . acceleration due to gravity
or, 420 = mass . 9.8
therefore mass = 42.85 kg

What are the assumptions that we should check before conducting the hypothesis test?
Answer:
Assumptions before conduction hypothesis test are mentioned below in the explanation.
Step-by-step explanation:
As this question is incomplete, and I will try my best to answer this question.
We are asked in this question to write the assumptions that we check before conducting the hypothesis test.
Solution:
Assumptions of hypothesis test:
1. We have to make assumption that all the observations are independent.
2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.
3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).
Above are the assumptions that we should check before conducting hypothesis test.

Answer:
5) x = 21, y = -13
6) x = 20, y = -2
I don't know how to get #7, I'm sorry.
Step-by-step explanation:
5) 4x - 3(8 - x) = -3
4x - 24 - 3x = -3
+24 +24
4x - 3x = 21
x = 21
y = 8 - 21
y = -13
6) x + 3y = 14
-3y -3y
x = -3y + 14
-5(-3y + 14) + 6y = -28
15y + 14 +6y = -28
21y + 14 = -28
-14 -14
21y = -42
÷21 ÷21
y = -2
x + 3(-2) = 14
x + -6 = 14
+6 +6
x = 20

The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The amount Liam got on his 18th birthday is $34,251.05.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
Example:
P = 200
R = 2%
t = 3 years
compounded annually, n =1
A = $212.24
We have,
Principal = $20,000
Rate = 3%
There are 4 quarters in a year.
It is compounded quarterly.
This means,
n = 4
t = 18 years
The amount compounded quarterly.
A = 20,000 [tex](1 + 0.0075)^{72}[/tex]
A = 20,000 x [tex]1.0075^{72}[/tex]
A = $34,251.05
Thus,
The amount Liam got on his 18th birthday is $34,251.05.
