Applying the linear angles theorem, the measures of the larger angles are: 130 degrees.
The measures of the smaller angles are 50 degrees
How to Apply the Linear Angles Theorem?Based on the linear angles theorem, we have the following equation which we will use to find the value of y:
3y + 11 + 10y = 180
Add like terms
13y + 11 = 180
Subtract 11 from both sides
13y + 11 - 11 = 180 - 11
13y = 169
13y/13 = 169/13
y = 13
Plug in the value of y
3y + 11 = 3(13) + 11 = 50 degrees
10y = 10(13) = 130 degrees.
Therefore, applying the linear angles theorem, the measures of the larger angles are: 130 degrees.
The measures of the smaller angles are 50 degrees.

Write 3 and 3/4 as a decimal. Is it repeating or terminating?
Answer:
3.75, Terminating
Step-by-step explanation:
To answer this, we simply have to find what 3/4 is as a decimal. So, we know that in order to make 4/4, or 1, we need 4 parts. Let's say that 4/4 would equal 100, so we need to divide 100 into 4 parts:
100 / 4 = 25
Now, to find what 3/4 is, all we have to do is multiply 25 by 3:
25 * 3 = 75
And that is our decimal form, we just need to add the 3:
3.75, and since .75 doesn't keep on repeating, it just stops at .75, this is a terminating decimal

Igor has not been skiing in 10 years. however, when he gets on his skis, his body remembers exactly how to ski. the kind of memory that makes it possible for him to remember how to ski is procedural.
What is procedural memory?Procedure memory exists a kind of implicit memory (unconscious, long-term memory) that helps people carry out particular tasks without thinking about their previous experiences. It frequently resides below the consciousness level and controls the actions we take. The automatic retrieval and use of procedural memories, which are relied upon when appropriate, is necessary for the execution of integrated motor and cognitive functions, such as tying shoes, reading, and flying an airplane. Procedural memories are recovered and used without any conscious control or attention being needed. Procedural learning, or repeatedly completing a challenging activity until all required brain networks are able to coordinate to complete the job automatically, is how procedural memory is established.To learn more about procedural memory, refer to:

Why cant charge separation within the could exist forever
Charge separation within a cloud cannot exist forever due to several factors, including the electrical forces and atmospheric conditions.
What is meant by charge seperation?
Charge separation refers to the redistribution or accumulation of electric charges within a system or object, resulting in an uneven distribution of positive and negative charges.
Electrical forces: Charge separation occurs within a cloud due to the buildup of positive and negative charges in different regions. However, these charges create an electric field that exerts a force on the opposite charges. Over time, this electric force causes the charges to move toward each other, neutralizing the separation. The attraction between opposite charges will eventually overcome the separation and lead to the discharge of the accumulated electrical energy as lightning.
Atmospheric conditions: The atmosphere contains various particles and gases that can affect charge separation. Air molecules, for example, can become ionized, leading to the formation of ions and facilitating electrical conductivity. Additionally, turbulence and air currents within the cloud can mix and redistribute the charges, minimizing the separation. The complex and dynamic nature of the atmosphere makes it difficult for charge separation to be maintained indefinitely.
Path of least resistance: Charge separation within a cloud occurs as a result of different charge densities in different regions. However, nature tends to seek equilibrium, and the electrical energy will discharge along the path of least resistance to restore balance. This discharge occurs in the form of lightning, where the accumulated charges are rapidly neutralized through a discharge channel that provides the easiest path for the electrical energy to dissipate.
In summary, charge separation within a cloud cannot exist indefinitely due to the influence of electrical forces, atmospheric conditions, and the tendency for nature to seek equilibrium. Eventually, the charges will dissipate and neutralize, leading to a discharge such as lightning.

Solve the simultaneous equations by substitution 2 x − 3 y = 8
Answer:
To solve the simultaneous equations by substitution, we can first solve one equation for one of the variables, and then substitute that expression into the other equation. Here is one way to solve the given equation:
2x - 3y = 8
We can solve for x by adding 3y to both sides:
2x = 3y + 8
We can divide both sides by 2 to get x by itself:
x = (3y + 8)/2
Now we can substitute this expression for x into the other equation:
2((3y + 8)/2) - 3y = 8
Simplifying and solving for y:
3y + 8 - 3y = 8
8 = 8
So the solution for y is any value.
Now we can substitute the value of y into the equation x = (3y + 8)/2 and we'll get the value of x.
x = (3 * y + 8) / 2
For example if we substitute y = 2
x = (3 * 2 + 8) / 2 = 14/2 = 7
So the solution for the simultaneous equations is x = 7, y = 2

John, Jim and Joe each went for a medical examination. Their combined height was 5.25 m. If John was 12 cm shorter than Jim and Jim was 0.09 m taller than Joe, how tall, in metres, was Joe?
The 5.25 m combined height of John, Jim, and Joe, the 12 cm height difference between John and Jim and the 0.09 m difference in height between Jim and Joe, indicates that solution to the word problem is Joe was 1.73 meters tall
What is a word problem?A word problem is a presentation of a math problem using verbal description rather than numbers, variables and operators.
The combined height of John, Jim and Joe = 5.25 m
John's height = Jim's height - 12 cm = Jim's height - 0.12
Jim's height = Joe's height + 0.09 m
Let h represent Joe's height, we get;
Jim's height = h + 0.09
John's height = h + 0.09 - 0.12 = h - 0.03
John's height = h - 0.03
The sum of the heights is therefore; h + h + 0.09 + h - 0.03 = 3·h + 0.06
The sum of their heights = Their combined height = 5.25 meters
Therefore; 3·h + 0.06 = 5.25
h = (5.25 - 0.06)/3 = 1.73
Joe's height, h = 1.73 meters
Jim's height = 1.73 + 0.09 = 1.82
Jim's height = 1.82 meters
John's height = 1.73 - 0.03 = 1.7
John's height is 1.7 meters
Joe was 1,73 meters tall

The volume of the cone is one-third the volume of the pyramid, the area of the circle is pi/4 the area of the square because the radius of the circle is half the side length of the square.
The volume of the cone is one-third the volume of the pyramid because the cone's base is a sector of the square, and the sector takes up one-third of the square's area.
Volume of a cone: The volume of a cone is equal to (1/3)πr²h, where r is the radius of the base and h is the height of the cone.
Volume of a pyramid: The volume of a pyramid is equal to (1/3)Bh, where B is the area of the base and h is the height of the pyramid.
In the problem, we are told that the area of the circle is pi/4 the area of the square. This means that the radius of the circle is half the side length of the square. We can use this information to find the volume of the cone and the pyramid.
Volume of the cone: The radius of the cone is half the side length of the square, so r = s/2. The height of the cone is h. The area of the base of the cone is (pi)(r²) = (pi)(s²/4). So, the volume of the cone is (1/3)π(s²/4)h = (1/12)πs²h.
Volume of the pyramid: The area of the base of the pyramid is the same as the area of the base of the cone, which is (pi)(s²/4). The height of the pyramid is the same as the height of the cone, which is h. So, the volume of the pyramid is (1/3)π(s²/4)h = (1/12)πs²h.
As you can see, the volume of the cone is equal to one-third the volume of the pyramid.

Juan scored 15 points more than on this test than his previous test. If the average of the two tests is at least 92 and both scores are integers what are the least scores he could have had on the two tests.
The least scores Juan could have had in the two tests are 85 and 100
How to determine the possible scores on the tests?Let the test scores be x and y
Where x is the current test and y is the previous test
Using the interpretation of the parameters in the question, we have the following:
x = y + 15 --- the relationship between the test scores
The average test scores can be represented as
1/2(x + y) ≥ 92
Substitute x = y + 15 in 1/2(x + y) ≥ 92
1/2(y + 15 + y) ≥ 92
Evaluate the like terms
1/2(2y + 15) ≥ 92
So, we have
2y + 15 ≥ 184
This gives
2y ≥ 169
Divide by 2
y ≥ 84.5
From the question both numbers are integers
So, we can assume that y = 85
Substitute y = 85 in x = y + 15
x = 85 + 15
Evaluate
x = 100
Hence, the possible test scores are 85 and 100

Find the particular antiderivative that satisfies the following conditions:
dy/dx (4x+5)/(3root(x)) ; y(1) = 8
The particular antiderivative that satisfies the given conditions is y(x) = 2x^(3/2) + 5x^(1/2) - 3x.
To find the particular antiderivative that satisfies the given conditions, we will integrate the given function with respect to x and then use the initial condition to determine the constant of integration.
The given function is: (4x + 5) / (3√x).
First, we split the function into two parts:
(4x) / (3√x) + (5) / (3√x).
Now, we integrate each part separately:
∫ (4x) / (3√x) dx = 2x^(3/2) + C1, where C1 is the constant of integration for the first part.
∫ (5) / (3√x) dx = 5x^(1/2) + C2, where C2 is the constant of integration for the second part.
Combining the two parts, we have:
y(x) = 2x^(3/2) + 5x^(1/2) + C, where C = C1 + C2.
Next, we use the initial condition y(1) = 8 to determine the value of C:
y(1) = 2(1)^(3/2) + 5(1)^(1/2) + C = 2 + 5 + C = 7 + C = 8.
Solving for C, we have: C = 8 - 7 = 1.
Therefore, the particular antiderivative that satisfies the given conditions is:
y(x) = 2x^(3/2) + 5x^(1/2) + 1.
The particular antiderivative that satisfies the given conditions is y(x) = 2x^(3/2) + 5x^(1/2) + 1. This antiderivative is obtained by integrating the given function and including the constant of integration determined by the initial condition y(1) = 8.
