According to the given information, the one angle on the straight line inside a circle is 135 then the value of the x = 4 as both angles are supplementary angles.
What are supplementary angles?Supplementary angles are two angles whose sum is 180 degrees. In other words, if we add the measures of two supplementary angles, the result is always 180 degrees.
When two lines intersect, they form four angles at the intersection point. If two of these angles are supplementary, they are called adjacent supplementary angles. In this case, they share a common side and a common vertex, and their non-shared sides form a straight line.
For example, if angle A and angle B are adjacent angles, and angle A measures 120 degrees, then angle B must measure 60 degrees, since 120 + 60 = 180.
According to the given informationIf the two angles are on a straight line, then they are supplementary, meaning their sum is 180 degrees. Therefore, we can set up the equation:
135 + (11x + 1) = 180
Simplifying the left side, we get:
136 + 11x = 180
Subtracting 136 from both sides, we get:
11x = 44
Dividing both sides by 11, we get:
x = 4
Therefore, the value of x is 4.

Myron's family is putting a pool in their backyard. He is so excited that he wants to figure out how
long it will take to fill the pool! He found the blueprints for the pool and recreated the sketches at
right, but he is not quite sure how to use them to find the volume of the pool.
What three-dimensional figures does Myron need to be able to find the volume of before he can
determine the volume of the pool?
To find the volume of an irregular 3D shape like Myron's pool, he needs to determine:
1. The length
2. The width
3. The depth
With those three measurements, he can plug them into the formula for volume of a rectangular prism:
Volume = Length x Width x Depth
So if the pool is:
Length = 20 ft
Width = 10 ft
Depth = 5 ft
Then the volume would be:
20 ft x 10 ft x 5 ft = 1000 cubic feet
Does this make sense? Let me know if Myron has any other questions!
Suppose the Baseball Hall of Fame in Cooperstown, New York, has approached Hobby−Cardz with a special order. The Hall of Fame wants to purchase 51,000 baseball card packs for a special promotional campaign and offers $0.43 per pack, a total of $21,930.

The solution of Unit Problem is Solution of first part is As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz,and second part is total profit is negative
What is contribution margin ?Contribution margin is the difference between a product's revenue and its variable costs. It represents the amount of money that is available to cover fixed costs and contribute to profit.
According to given information?1)Incremental Analysis without special order:
Revenue from 51,000 packs at $0.43 per pack = $21,930
Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830
Contribution margin = $21,930 - $16,830 = $5,100
As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz.
2)Incremental Analysis with special hologram baseball cards:
In addition to the incremental analysis performed in Part 1, we need to consider the additional cost of $5,300 to develop the hologram.
Revenue from 51,000 packs at $0.43 per pack = $21,930
Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830
Contribution margin = $21,930 - $16,830 = $5,100
Less: Additional cost of hologram development = $5,300
Total profit/loss = $5,100 - $5,300 = ($200)
As the total profit is negative, accepting the special sales order with the hologram development cost would result in a loss of $200. Therefore, Hobby-Cardz should not accept the special order under these circumstances.

A plane moving at 450 miles per hour is flying in your direction. At one moment the angle formed between the ground and your line of sight to the plane is 45 degrees. One minute later the angle is 60 degrees. Find the altitude of the plane. Make sure to draw a complete diagram, show all calculations and explain your process.
The altitude of the plane is approximately 21.65 miles.
What is altitude means ?An altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex).
We have an observer on the ground (you) and a plane flying towards you. Let's call the distance between the observer and the point directly below the plane "x", and let's call the altitude of the plane "h".
At the first moment, the angle between the ground and your line of sight to the plane is 45 degrees. This means that the angle between the plane's altitude and the ground is also 45 degrees (since the plane is flying horizontally towards you). We can use trigonometry to find the value of "x" in terms of "h".
In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:
tan(45) = h/x
Since tan(45) = 1, we can simplify this to:
h/x = 1
h = x
So the distance between the observer and the point directly below the plane is equal to the altitude of the plane.
One minute later, the angle between the ground and your line of sight to the plane is 60 degrees. We can use the same approach to find the new value of "x" in terms of "h".
In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:
tan(60) = h/(x + 450/60)
Simplifying this, we get:
h = (x + 7.5h) * sqrt(3)
Solving for "x", we get:
x = (h / sqrt(3)) - 7.5h
Now we can substitute the value of "x" from the first moment (which is equal to the altitude of the plane) into this equation to find the altitude of the plane:
h = (h / sqrt(3)) - 7.5h
h = h(1 / sqrt(3) - 7.5)
h = 21.65 miles (rounded to two decimal places)
Therefore, the altitude of the plane is approximately 21.65 miles.

Find the derivative of y = ((2x - 1) ^ 3)//√(3x + 1)
The derivative of the function y = ((2x - 1)³)/√(3x + 1) is dy/dx = (2x - 1)²[3x + 6]/(2[√(3x + 1)]³)
What is the derivative of a function?The derivative of a function is the limit as the change in x tnds to zero of the change in y over the change in x.
To find the derivative of the function y = ((2x - 1)³)/√(3x + 1), we use the quotient rule.
dy/dx = (vdu/dx - udv/dx)/v²
where u = (2x - 1)³ and v = √(3x + 1)
So, du/dx = 3(2x - 1)² and dv/dx = 3/[2√(3x + 1)]
Substituting the values of the variables into the equation, we have that
dy/dx = (vdu/dx - udv/dx)/v²
dy/dx = (√(3x + 1) × 3(2x - 1)² - (2x - 1)³ × 3/[2√(3x + 1)])/[√(3x + 1)]²
dy/dx = (3√(3x + 1)(2x - 1)² - 3(2x - 1)³/[2√(3x + 1)])/[√(3x + 1)]²
= (3√(3x + 1)√(3x + 1)(2x - 1)² - 3(2x - 1)³/[2√(3x + 1)])(3x + 1)²
= [3(3x + 1)(2x - 1)² - 3(2x - 1)³/[2√(3x + 1)])(3x + 1)²
= (2x - 1)²[3(3x + 1) - 3(2x - 1)/[2√(3x + 1)])(3x + 1)²
= (2x - 1)²[9x + 3 - 6x + 3]/[2√(3x + 1)])(3x + 1)²

how much to subtract from 53/6 to make 8
Answer:
We need to subtract 41/6 from 53/6 to get 8. Alternatively, we can say that 8 is 41/6 less than 53/6.
Step-by-step explanation:
To determine how much to subtract from 53/6 to make 8, we need to perform the following calculation:
53/6 - x = 8
where x is the amount we need to subtract.
To isolate x, we need to isolate it on one side of the equation. We can do this by subtracting 53/6 from both sides:
53/6 - x - 53/6 = 8 - 53/6
Simplifying the left-hand side gives:
-x = 8 - 53/6 + 53/6
Simplifying the right-hand side gives:
-x = 41/6
Multiplying both sides by -1 gives:
x = -41/6
Therefore, we need to subtract 41/6 from 53/6 to get 8. Alternatively, we can say that 8 is 41/6 less than 53/6.

Let A be the event that William walks the dog after school, and let B be the event that he does his homework.
We are given:
P(A) = 8/11
P(B|A) = 1/2 (the probability of doing homework given that he walks the dog)
P(B|A') = 3/4 (the probability of doing homework given that he doesn't walk the dog)
We want to find P(B), the probability that William does his homework. We can use the law of total probability, which states that:
P(B) = P(A)×P(B|A) + P(A') × P(B|A')
Substituting the values we have, we get:

The following headline refers to change. Identify the change as absolute or relative.
"Enrollments at Northeastern University are expected to increase by 1,700 students"
The change referred to in the headline is an absolute change. An absolute change is a difference or increase in a quantity that is measured without reference to the original or initial value.
In this case, the headline states that enrollments at Northeastern University are expected to increase by 1,700 students. This means that the actual number of students is expected to increase by 1,700 from its current or previous level, without any reference to the original number of students enrolled at Northeastern University.
An absolute change is usually expressed in units of the quantity being measured, such as students, dollars, or meters. In contrast, a relative change is expressed as a percentage or ratio of the original or initial value. A relative change indicates how much a quantity has changed in proportion to its initial value.
For example, if enrollments at Northeastern University were expected to increase by 10%, this would be a relative change because it represents a percentage of the current or previous level of enrollment. However, the headline specifies an absolute increase of 1,700 students, which does not depend on the current or previous level of enrollment.

The rectangle have length = 4, breath = 16, perimeter = 40, and area = 64.
How to evaluate for the length, breadth, perimeter, and area of the rectangleThe perimeter of a rectangle is the sum of length of its four sides or the sum of its length and breadth, multiplied by two. While the area is the length multiplied by the breadth.
Perimeter = 2(L + B)
Area = L × B
From the question;
2(L + B) = 2LB
32L = 2L(L²)...(1) {since B = L²}
from equation (1), L = 4 by solving for L
so;
B = 4² = 16
perimeter of the rectangle = 2(4 + 16) = 40
area of the rectangle = 4 × 16 = 64
Therefore, the rectangle have length = 4, breath = 16, perimeter = 40, and area = 64.
