(A) n=w by the corresponding angles theorem.
(B) This is the correct answer. n=s by the vertical angles theorem and s and x are supplementary by the same-side interior angles theorem. Thus, n and x are supplementary, and are not always equal.
(C) n=z by the alternate exterior angles theorem.
(D) s=w, so (s+w)/2 = (s+s)/2 = s. Since n=s by the vertical angles theorem, n=s.
(E) n and w are equal by the corresponding angles theorem, and w and y are supplementary as they form a linear pair. Thus, n+y=180, and it follows n=180-y.
Determine the endpoints of the midsegment connecting side YX and side YZ
Answer:
endpoint of midsegment connecting side YX is (4, 3)
endpoint of midsegment connecting side YZ is (5, -1)
Step-by-step explanation:
Mid point of a line segment - it is the middle point of a line segment. It is equidistant from both endpoints and it is the centroid both of the segment and of the endpoints.
according to the graph;
Y is (1, 2), Z is (9, -4), X is (7, 4)
therefore using mid point formula we can determine the endpoints of midsegments connecting side YX and YZ
if (x , y) and (x1, y1) are the endpoints of a line then;
The coordinates of mid point are given by the formula = (x+x1)/2, (y+y1)/2
using the above formula mid point of YX is
(7+1)/2, (4+2)/2 = (4, 3)
and the mid point of line YZ is
(9+1)/2, (-4+2)/2 = (5, -1)
hence the answer is (4,3) and (5, -1)

The exchange rate of Mexican pesos for US dollars is approximately 19 pesos for 1 dollar if Lynn exchanges 4,000 pesos for US dollars what was the approximate value in US dollars
Unit conversion is a way of converting some common units into another without changing their real value. The approximate value in US dollars is $210.53.
What is unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
The exchange rate of Mexican pesos for US dollars is approximately 19 pesos for 1 dollar. Therefore, we can write,
19 pesos = 1 dollar
1 pesos = 1/19 dollar
if Lynn exchanges 4,000 pesos for US dollars, then the approximate value in US dollars will be,
4,000 pesos = 4000/19 = 210.53 dollars
Hence, the approximate value in US dollars is $210.53.

i’ve done the graph which is part a and b but i need help in part c and d, help will be appreciated!
Answer:
(a) see below
(b) see attached
(c) (15, 180) is not on the line
(d) a = -40
Step-by-step explanation:
Given equation:
[tex]y = 10x+20[/tex]
Part (a)
To complete the table of values, simply substitute each value of x into the given equation:
[tex]x=-3 \implies y=10(-3)+20=-10[/tex]
[tex]x=-1 \implies y=10(-1)+20=10[/tex]
[tex]x=0 \implies y=10(0)+20=20[/tex]
[tex]x=1 \implies y=10(1)+20=30[/tex]
[tex]x=3 \implies y=10(3)+20=50[/tex]
[tex]\large \begin{array}{| c | c | c | c | c | c | c | c |}\cline{1-8} x & -3 & -2 & -1 & 0 & 1 & 2 & 3\\\cline{1-8} y & -10 & 0 & 10 & 20 & 30 & 40 & 50\\ \cline{1-8} \end{array}[/tex]
Part (b)
Plot 2 points from the table and draw a straight line through them.
Part (c)
To determine if (15, 180) is on the line, substitute x = 15 into the given equation of the line:
[tex]\begin{aligned} x=15 \implies y & =10(15)+20\\& = 150 + 20\\& = 170\end{aligned}[/tex]
Therefore (15, 180) is not on the line
Part (d)
If (-6, a) is on the line, substitute x = -6 and y = a into the equation and solve for a:
[tex]\begin{aligned} y & = 10x+20\\\implies a & = 10(-6)+20\\a & = -60 + 20\\a & = -40\end{aligned}[/tex]
Therefore, a = -40

A number line from negative 3 to 3 in increments of 1. An open circle is at negative 5 and a bold line starts at negative 5 and is pointing to the left.
The correct simplified inequality is - 6x + 15 < 10 - 5x and the number line representation is "an open circle is at 5 and a bold line starts at 5 and is pointing to the right".
The given inequality is -3(2x - 5) < 5(2 - x)
We need to simplify the inequality.
What is inequality?In mathematics, inequality is a statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
Consider LHS and simplify -3(2x - 5) = -3(2x)-5(-3)
⇒ -3(2x - 5) = - 6x + 15 [∵(-)(-) = (+)]
Consider RHS and simplify 5(2 - x) = 5(2) + 5(-x)
⇒5(2 - x) = 10 - 5x [∵(+)(-) = (-)]
Now, - 6x + 15 < 10 - 5x
By subtracting 15 from both sides, we get
- 6x < -5 - 5x
By adding 5x to both sides, we get - x < - 5
The coefficient of x is -1. So, divide both sides by -1
Then we get x > 5
Hence, the correct simplified inequality is - 6x + 15 < 10 - 5x and the number line representation is "an open circle is at 5 and a bold line starts at 5 and is pointing to the right".

The loudness, L, measured in decibels (Db), of sound intensity, I, measured in watts per square meter, is defined as L = 10 log StartFraction I Over I 0 EndFraction, where I 0 = 10 Superscript negative 12 and is the least intense sound a human ear can hear. What is the approximate loudness of a dinner conversation with a sound intensity of 10–7?
The correct option is Option D: the approximate loudness of a dinner conversation will be 50Db with a sound intensity 10⁻⁷.
The loudness L, ( which is measured in decibels (Db)), of the sound of the intensity I, can be calculated in watts per square meter,
L = 10 log(I/I₀)
where I₀ = 10⁻¹² which is the least intensity that a human can hear.
The sound intensity of a dinner conversation= I= 10⁻⁷
Loudness L of that conversation = 10 log (10⁻⁷/10⁻¹²)
= 10 log(10⁻⁷⁻⁽⁻¹²⁾)
= 10 log(10⁻⁷⁺¹²)
= 10 log(10⁵)
= 10*5
= 50 Db
