This is another way of saying two angles next to each other add to 90 degrees. In other words, two angles touching each other forming a corner.
Two adjacent angles can be supplementary, so choice B is false.
An acute angle is always adjacent to an obtuse angle, so choice C is false.
Two right angles can be adjacent, and they would form a straight (180 degree) angle, so that's why choice D is false.

a. Find the difference in the two data provided.
b. Calculate the sum of the two data to the nearest thousand hundred.
a. the difference in the two data provided =31072940 - 24658823 = 6414117
b. the sum of the two data to the nearest thousand hundred = 31072940 - 24658823 = 55731763

Your teacher asked your class to describe a real world situation in which a intercept is 50 and the slope is -10. Your partner gave the followingdescription: My friend started with $50 and earned $10 every week from dding chores. What mistake did your partner make?2
The equation of a line can be written as:
y = mx + b
Where m is the slope and b is the y-intercept.
For the word problem, the slope is -10 and the intercept is 50, thus the equation is:
y = -10x + 50
If x is the number of weeks, then y decreases by 10 when x increases by 1. We expect that the value of y goes from 50 down to 40, 30, 20, etc.

The conjecture "for n > 3, all n-gons have an even number
of sides" is disproved by which statement?
A Hexagons have six sides.
B Pentagons have five sides.
1
Octagons have eight sides.
Quadrilaterals have four sides.
Answer:
pentagons have five sides
Step-by-step explanation:
We want to find out why the statement disprove the conjecture
What the conjecture assumes is that for all polygons with more than 3 sides, all polygons here having their names ending in ‘gons’ have an even number of sides
The term pentagon refers to a 5-sided polygon
This polygon thus have more than 3 sides. Since 5 is not an even number, then we can conclude that the conjecture has been disproven

Answer:
A. The slope is \(\frac{3}{2}\)
B. the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point.
Step-by-step explanation:
PART A: Slope
Given tangent line;
\(y = \frac{3x}{2} + \frac{9}{2}\)
The slope of the tangent line is equal to the derivative of the function;
\(\frac{dy}{dx} =\frac{3}{2}\)
the slope = \(\frac{3}{2}\)
PART B: Correct statement that describe the slope of a tangent line:
A secant line is a straight line joining two points on a function and the slope of the function is equal to average rate of change of the function between the two points.
A tangent line is a straight line that touches a function at only one point, and the slope of the function is equal to the instantaneous rate of change of the function at that one point.
Thus, the correct statement is " the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point".

the six sigma dmaic approach is the best way to attack all problems and should be employed whenever possible. true or false?
False. The Six Sigma DMAIC approach is one of many problem-solving methods that can be used, and is most appropriate when the problem is complex and the potential solutions are not immediately evident.
Six Sigma DMAIC (define, measure, analyze, improve, control) is a strategy used to improve processes and products. It is designed to help companies identify and eliminate defects and reduce variability in their processes. It is not the best way to attack all problems, as there are many other problem-solving methods, such as Design Thinking and Lean, that may be more suitable solution depending on the complexity of the problem.

Therefore , the solution of the given problem of median comes out to be R students still present (maximum) =35
Explain median.The number that precisely falls in the center of a sorted collection is the median value. An average or maximum probability metric is the difference between the initial and final 50% of the data. Different algorithms are employed to compute the average and mode depending on if you do have an unusual or perhaps even number of data points.
Here,
Median is 55
P :Q: R :S :average of 45 :50: 55 :65
The number of pupils within every section needs to be as low as possible
R is a mean
P differs by 1: 10 from the mean.
Q is 1.5 away from the mean.
Then S will just have three students, or three times five, to keep the population's mean constant.

Answer:
The diameter of the floor is 6 yards
Step-by-step explanation:
Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards
Mathematically,
C = π * D
where C is the circumference
Plugging the values of the circumference , we have ;
18.84 = 22/7 * D

A construction crew has just built a new road. They built the road at a rate of \( 5.12 \) kllometers per week. They worked for 4 weeks. How many kilometers of road did they build?
If the construction crew built the road at a rate of 5.12 kilometers per week and worked for 4 weeks, the number of kilometers they built is 20.48 kilometers.
What is the rate?The rate refers to the speed or the average by which an action is performed per a measurement unit.
The rate can be computed as the ratio of one value or quantity in relation to another.
The building rate per week = 5.12 km per week
The number of work weeks = 4
The total number of kilometers of road constructed within 4 weeks = 20.48 (5.12 x 4)
Thus, given the rate of construction per week, the construction crew built 20.48 kilometers of road in 4 weeks.

The area of the square is 21.4c * m ^ 2 truncated to 1 decimal place. Write the error interval for the area, a, of the shaded region in the form m < a < n .
The error interval for the area of the shaded region is given as follows:
56.6 < a < 56.8.
How to obtain the error interval?The area of the circle is of 78.1 cm², rounded to one decimal place, hence the interval for the area of the circle is of:
78.05 <= area circle < 78.15.
The area of the square is of 21.4 cm², rounded to one decimal place, hence the interval for the area of the circle is of:
21.35 <= area square < 21.45.
The error formula is:
Area circle - Area square.
The minimum error is when the area of the circle is the greatest and the square is the least, hence:
m = 78.15 - 21.35
m = 56.8.
The maximum error is when the area of the circle is the least and the square is the greatest, hence:
n = 78.05 - 21.45

Triangle ABC is transformed to triangle A’B’C’, as shown below:
Which equation shows the correct relationship between the measures of the angles of the two triangles?
Suppose you know that ∠S and ∠Y are complementary and that m∠S = 2(m∠Y) − 30°. Find m∠Y.
Answer:
Step-by-step explanation:
Since ∠S and ∠Y are complementary, we have:
∠S + ∠Y = 90°
We also know that:
m∠S = 2(m∠Y) − 30°
Substituting the second equation into the first equation, we get:
2(m∠Y) − 30° + ∠Y = 90°
Combining like terms:
3(m∠Y) = 120°
Dividing both sides by 3:
m∠Y = 40°
Therefore, m∠Y is 40 degrees.
What is the slope of the line 6x + y = 24?
Answer:
-6
Step-by-step explanation:
You need to get it in Point-Slope form, or
y = mx + b
Isolate y by subtracting 6x
You are left with:
y = -6x + 24
M is the slope, so in this case, it is -6
Answer:
The slope is -6/1 but the slope-intercept form is y=-6x+24
Step-by-step explanation:
y=mx+b
6x+y=24
first you want to subtract 6x from each side.
y=-6x+24
m=-6x or -6/1

To solve a polynomial inequality, find the ________ numbers of the polynomial, and use these numbers to create ________ ________ for the inequal
To solve a polynomial inequality, The resulting values of x are the critical numbers.Once you have the critical numbers, you can use them to create test intervals for the inequality.
The critical numbers divide the number line into test intervals. Next, choose a test point from each interval and substitute it into the polynomial inequality. If the result is positive, then all values in that interval satisfy the inequality. If the result is negative, then the values in that interval do not satisfy the inequality.
When solving a polynomial inequality, it is important to find the critical numbers of the polynomial. These are the values of x where the polynomial is equal to zero or undefined. To find the critical numbers, set the polynomial equal to zero and solve for x.

∠3 = ∠76x+8 = 8x-76x-8x = -7-8-2x = -15x = -15/-2x = 15/2Now calculate the angles of ∠3 and ∠7.
∠36x+86×15/2+845+853°∠78x-78×15/2-760-753°Now we can see that ∠3 and ∠1 are alternate angles and ∠7 and ∠1 are alternate exterior angles. Thus, we can say that
