Given: mAngleTRV = 60° mAngleTRS = (4x)° Prove: x = 30 3 lines are shown. A line with points T, R, W intersects with a line with points V, R, S at point R. A line extends from point R to point Z between angle V R W. Angle V R T is 60 degrees and angle T, R, S is (4 x) degrees. What is the missing reason in step 3?
Answer:
the answer is angle addition postulate
Step-by-step explanation:
Given the proof for x = 30, the missing reason in step 3 is: angle addition postulate
What is Angle Addition Postulate?Angle addition postulate states that if D is the interior of ∠ABC, therefore, the sum of the smaller angles equals the sum of the larger angle, which is: m∠ABD + m∠DBC = m∠ABC.
The given diagram as shown in the image attached below alongside the proof of x = 30.
T is the interior of straight angle ∠VRS.
m∠VRS = 180° (straight line angle)
Therefore, based on the angle addition postulate, m∠TRS + m∠TRV = 180°.
Thus, given the proof for x = 30, the missing reason in step 3 is: angle addition postulateLearn more about angle addition postulate on:

find the interval between: 8:40 pm and 9:30 am
Answer:
12 hours 50 minutes
Step-by-step explanation:
8:40 pm to 9:30 am
8:40 pm to 8:40 am = 12 hours
8:40 am to 9:30 am = 50 minutes
The interval between 8:40 pm and 9:30 am is 12 hours and 50 minutes
What is an Interval?
An interval is measured in terms of numbers. An interval includes all the numbers that come between two particular numbers. This range includes all the real numbers between those two numbers.
Given data ,
Let the interval be denoted as [ a , b ] , where a is the start point and b is the final point
Now ,
a = 8:40 pm
b = 9:30 am
The interval can be calculated by ( b - a )
8:40 pm → 8:40 am = 12 hours
8:40 am → 9:30 am = 50 minutes
Therefore , total interval = 12 hours and 50 minutes
Hence , The interval between 8:40 pm and 9:30 am is 12 hours and 50 minutes

if ef bisects aed, aef=4x+3 and fed=7x-33 find m
Answer:
aef = fed = 51 degrees,
and the full angle aed = 102 degrees
Step-by-step explanation:
If ef bisects the angle aed, then the two angles it defines: aef and fed, must measure the same.
Therefore we can asume that aef = fed which numerically means:
4 x + 3 = 7 x - 33
so we solve for x:
33 + 3 = 7 x - 4 x
36 = 3 x
x = 36/3
x = 12 degrees
That means that the half angle aef measures:
aef = 4 x + 3 = 4 (12) + 3 = 48 + 3 = 51 degrees
Then we have that aef = fed = 51 degrees,
and the full angle aed = 51 + 51 = 102 degrees

the slope of the line that passes through the point (2 4) and (3 8) is
Answer:
y - 4 = 4(x - 2)
Step-by-step explanation:
Please write these points as (2, 4) and (3, 8) (use commas and parentheses).
As we move from (2, 4) to (3, 8), x increases by 1 and y increases by 4. Thus, the slope is m = rise/run = 4/1 = 4
and the equation of the line through these two points (in point-slope form) is
y - 4 = 4(x - 2)
The slope of the line that passes through the point (2 4) and (3 8) is 4
The formula for calculating the equation of a line passing through the point (x1, y1) and (x2, y2) is expressed using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the coordinate points (2 4) and (3 8), the slope is expressed as:
[tex]m=\frac{8-4}{3-2}\\m=\frac{4}{1}\\m = 4[/tex]
Hence the slope of the line that passes through the point (2 4) and (3 8) is 4

Finding the mean
To find the mean, divide the sum of all the items by the number of items.
[tex] \boxed{ \sf{mean = \frac{Σx}{N} }}[/tex]
[tex] \dashrightarrow{ \sf{mean = \frac{120}{12} }}[/tex]

7. Three cubes of edges x cm , 6 cm, and 8 cm are melted and recast into a bigger cube of
edge 12 cm , find the value of x?
Answer:
10 cm³
Step-by-step explanation:
Volume of a cube = (Side)³
Volume of bigger cube = (12)³
(12)³ = 1728 cm³
Volume of three cubes = (x)³ + (6)³ + (8)³ = 1728
(x)³ = 1728 - (6)³ - (8)³
(x)³ = 1000
x = ∛1000
x = 10 cm³
A linear correlation scatterplot is also a direct proportionality. True or False
Answer: False
Step-by-step explanation: A linear correlation scatter plot is one which is aimed at establishing a graphical view of the relationship between two quantitative variables. A linear correlation scatter plot could either be positive which is depicted by a positive gradient which infers direct proportionality, this means an increase in variable A results in increase in variable B while a decrease in variable A results in decrease in variable B. Similarly, it could also exhibit a negative gradient which infers a inverse proportionality meaning a decrease in one variable leads to increase of the other and vice-versa. Hence, a linear scatterplot does not only exhibit direct proportionality.

A set of three scores consists of the values 3, 7, and 2. Σ2X-2 = 22 E(x-1)2 = -41 Hint: Remember to follow the order of mathematical operations.
Answer:
Step-by-step explanation:
Given the following scores 3, 7 and 2, we are to find the expression Σ2X-2 and Σ(X-1)²
The value of X's are 3, 7 and 2. Substituting the values we will have;
Σ2X-2 = [2(3)+2(7)+2(2)] - 2
Σ2X-2 = (6+14+4) - 2
Σ2X-2 = 24-2
Σ2X-2 = 22
For Σ(X-1)²
Σ(X-1)² = (3-1)²+ (7-1)² + (2-1)²
Σ(X-1)² = 2²+6²+1²
Σ(X-1)² = 4+ 36+1
Σ(X-1)² = 41
Σ2X - 2 = 22 , Σ( X - 1 )^2 = 41
Given : X = 3 , 7 , 2
Σ2X is calculated in the image = 24
Σ2X - 2 = 24 - 2 = 22
Σ( X - 1 )^2 calculation is shown, it is = 41

Time and Tide is the name of the question. A ship is at anchor. Over its side hangs a rope ladder with rungs a foot apart. The tide rises at the rate of 8 inches per hour. At the end of six hours how much of the rope ladder will remain above water, assuming that 8 feet were above water when the tide began to rise? Using complete sentences explain how you determined your answer.
Answer:
Hey there!
First, I converted 8 feet to inches. I knew that 12 inches were in a foot, so 96 inches are in 8 feet. If the water rises at 8 inches per hour, at the end of 6 hours, the water will rise 48 inches. Finally, subtracting 48 from 96, we get that there are 48 inches of rope above the water's surface.

The demand for a certain company's e-reader can be approximated byq =720p− 1 million units per year (60 ≤ p ≤ 400),where p is the price charged by the company. Assume that the company is prepared to supplyq = 0.018p − 1 million units per year (60 ≤ p ≤ 400)at a price of $p per unit.Calculate the equilibrium price and equilibrium demand.equilibrium price$equilibrium demand million e-readers per year.
Answer:
Equilibrium price P = 200 dollars
equilibrium demand of million e-readers per yer = 2.6 mi/yr
Step-by-step explanation:
Given that;
q = 720/p - 1 million units per year { 60 ≤ p ≤ 400 }
supply q = 0.018p − 1 million units per year (60 ≤ p ≤ 400)
we substitute
720/p - 1 = 0.018p − 1
720/p = 0.018p
720 = 0.018p^2
p^2 = 720/0.018 = 40000
p = sqrt(40000)
p = 200
substitute value of p
q = 0.018(200) − 1
q = 3.6 - 1 = 2.6
Therefore Equilibrium price P = 200 dollars
equilibrium demand of million e-readers per yer = 2.6 mi/yr
