Draw an example that supports Rylan's statement and draw a
counterexample that shows her statement is not always true.
The example of adjacent angles that are complementary and those that are non-complementary are given as attached.
What are adjacent and Non-Adjacent angles?When two adjacent angles have a similar vertex and side, they might be complementary or supplementary angles.
If the total of neighboring angles equals 90 degrees, then they are complementary. If the total of neighboring angles equals 180 degrees, they are complementary to one another.
Non-adjacent Complementary Angles: Two angles that are not next to each other are non-adjacent complementary angles. AOB and XOY are non-adjacent angles since they share neither a vertex nor an arm. They also add up to 90°. As a result, these two angles are non-adjacent complimentary.

A company sells confetti in boxes in the shape of a triangular pyramid. Each box contains
240 cubic centimeters of confetti. If the height of the box is 15 centimeters, which of the
following could be the dimensions of the base?
A. Base, 8 cm; height, 4 cm
B. Base, 4 cm; height, 4 cm
C. Base, 6 cm; height, 8 cm
D. Base, 12 cm; height, 8 cm
The dimensions of the base would be: base: 12 cm ; height : 8 cm
The correct answer is an option (D)
We know that the formula for the volume of a pyramid is:
V = 1/3 × B × h
where B is the base area of the pyramid
h is the height of the pyramid
The shape of the box is a triangular pyramid.
Each box contains 240 cubic centimeters of confetti.
this means, the volume of the box is V = 240 cubic centimeters
Using above formula of the volume of a pyramid,
V = 1/3 × B × h
here V = 240 cubic centimeters and h = 15 centimeters
240 = 1/3 × B × 15
240 = B × 5
B = 240/5
B = 48 square centimeters
The dimensions of the base must be such that the area of the base would be 48 square centimeters.
Here, a pyramid has triangular base.
Using the formula for the area of triangle,
B = 1/2 × base of triangle × height of triangle
48 = 1/2 × base of triangle × height of triangle
base of triangle × height of triangle = 96
for the dimensions Base, 12 cm; height, 8 cm
12 × 8 = 96
Thus, the dimension of the base: base of triangle = 12 cm and the height of triangle = 8 cm

Step-by-step explanation: I like to start by counting the x-values, then the y-values. Since the y-values are increasing by a constant of 3 and the x-values are increasing by 1, that would technically make the equation y = 3x + 0, but you don't need the 0 in this case.

Answer: ∠1= 53°
∠3, ∠6, ∠7 are all 127°
∠4,∠5,∠8 are all 53°
Step-by-step explanation: 127° and ∠1 are supplementary angles meaning they add up to 180° You subtract 127° from 180° to get 53°.
∠3 and 127°are vertical which makes them equal and both 127°.
∠4 is vertical to ∠1 which makes them equal and both 53°.
∠5 is corresponding to ∠1 so they are equal and both 53°.
∠6 is corresponding to 127° so they are equal and both 127°.
∠7 is vertical to ∠6 so they are equal and both 127°.
∠8 is vertical to ∠5 so they are equal and both 53°.
which of the following describes the domain of the piecewise function
Answer:
(c) (-∞, -2) ∪ (-2, 1) ∪ (1, ∞)
Step-by-step explanation:
You want the domain of the given piecewise-defined function.
x < 2For x < 2, the function is ...
[tex]g(x)=\dfrac{x^2+2x}{x^2+x-2}-\dfrac{x(x+2)}{(x-1)(x+2)}=\dfrac{x}{x-1}\quad x\ne\{-2,1\}[/tex]
Both of these exclusions are in the region x < 2, so both must be excluded from the domain.
x ≥ 2The log function is defined for all values x > -2, so there are no exclusions in this region.
The domain is (-∞, -2) ∪ (-2, 1) ∪ (1, ∞).

a farmer owns three full sections, four half-sections, and two quarter-sections. how many acres is this?
The correct option is Option 1 - 3520.
A farmer owns 3520 acres in which three full sections, four half-sections, and two quarter-sections are there.
Three of a farmer's sections were full. Let's say a full section is 640, which is
=3 x 640,
= 1,920.
He had four half portions as well. Divide 640 by two to get 320 (640/2), which is
= 4 X 320
= 1,280.
He had three quarter portions as well. Divide 640 by 4 to create a quarter piece (640/4 = 160)
= 2 X 160
= 320.
Now we have to add all these,
Three full sections = 1920
Four half-sections = 1280
Two quarter-sections = 320
= 1,920 + 1,280 + 320
= 3,520.
Therefore the acres a farmer had is 3520.

The value of the Population Variance is 25.
Given:
The standard deviation of a population is 5
The mean of a population is 50
The size of a population is 10
[tex]Variance = (Standard \ deviation)^{2}[/tex]
[tex]Variance = 5^{2}[/tex]
σ = 25.
So, The value of the Population Variance is 25.
Population variance is a metric for gauging how dispersed a set of data points is. It calculates the typical squared deviation from the mean. Therefore, the variance will be smaller if all of the data points are close to the mean than it will be if the data points are dispersed widely.
We are aware that the population variance describes the distribution of data points within a population by averaging the squared distances between each data point and the mean.

The answer for the given senary expressions is 35₆.
What are senary numbers?
A senary numeral system (also known as base-6, heximal, or seximal) has six as its base. It has been adopted independently by a small number of cultures. Like decimal, it is a semiprime, though it is unique as the product of the only two consecutive numbers that are both prime (2 and 3). As six is a superior highly composite number, many of the arguments made in favor of the duodecimal system also apply to senary.
Now,
To find 2434₆/42₆
2434\(_6\) to base 10
2 \(\times\) 6\(^3\) + 4 \(\times\) 6\(^2\) + 3 \(\times\) 6\(^1\) + 4 \(\times\) 6\(^0\)

Greg would need to visit his parents at least 18 times each year to attain gold status. To calculate this, we need to take the minimum flight miles required for gold status (16200) and subtract 900 miles, the round-trip flight distance to visit his parents.
where the value comes from the calculation of 15300 miles. Then, we divide 15300 miles by 900 miles, the round-trip flight distance to visit his parents, and get the answer of 18. Therefore, Greg needs to visit his parents at least 18 times each year to reach gold status. To be eligible for gold status, one must fly a certain amount of miles within a year.
For the airline company that Greg is using, the minimum flight miles required for gold status is 16200. Since Greg is taking a 900-mile round-trip flight to visit his parents, he needs to make up the difference in order to reach the minimum required flight miles.

What is the Quadratic Equation?
A quadratic equation is a type of polynomial equation that has the general form of ax^2 + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero. The degree of the equation is two, hence the name "quadratic".
x+1/6-y can be rewritten in terms of a,b, and c by using the following equation:
ax + by + c = 0
To get x+1/6-y in the values of a,b, and c we can rewrite the equation as follow:
a = 1, b = -1, c = -1/6
So, x+1/6-y can be written as:
