The reaction in which one (or more) hydrogen atoms of a hydrocarbon are replaced by some other atoms (like chlorine), is called a substitution reaction.
Substitution reaction is a type of chemical reaction in which an atom, ion, or group of atoms or ions in a molecule is replaced by another atom, ion, or group.
The examples of substitution reactions are as follows:
1. Reaction of copper with zinc sulphate gives zinc with copper sulphate by replacing the zinc with copper.
[tex]Cu + ZnSO_{4}[/tex] → [tex]CuSO_{4} + Zn[/tex]
2. Reaction of magnesium with copper sulphate gives magnesium sulphate with copper by replacing copper with magnesium.

What is the value of x in the triangle? a 45-45-90 triangle with leg length 7 and hypotenuse length x a. B. C. D.
The value of x in the given 45-45-90 triangle is 9.89.
The given triangle is a right-angled triangle which can be solved using the Pythagoras theorem. The Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the base and the square of the perpendicular. This theorem can be applied to all right-angled triangles.
In the given triangle, we have been told that the length of both legs is 7. Now, after applying the theorem -

Answer:
2.5 or 3.5
Step-by-step explanation:
You have an x-cm square and a rectangle ℓ cm by 3 cm. Together, they have a total perimeter of 32 cm. You want the length ℓ and the area S in terms of x, and you want to know the values of x that make the area be 30.25 cm².
(i) Wire lengthThe length of the wire is 32 cm. This is the sum of the perimeters of the square and the rectangle.
P = 4s +2(l+w)
32 = 4x + 2(ℓ +3) . . . . . . . . substitute given values
(ii) Rectangle lengthSolving the equation for ℓ, we have ...
16 = 2x +ℓ +3 . . . . . . . . . divide by 2
ℓ = 13 -2x . . . . . . . . . . . subtract 3+2x
(iii) Total areaThe total area of the two figures is the sum of the area of the square and that of the rectangle:
S = x² +3ℓ
S = x² +3(13 -2x) . . . . . . substitute for ℓ
S = x² -6x +39 . . . . . . . simplify
(iv) Value of xFor an area of 30.25 cm, we require ...
30.25 = x² -6x +39
-8.75 = x² -6x . . . . . . . . . . subtract 39
0.25 = x² -6x +9 . . . . . . . complete the square
±0.5 = x -3 . . . . . . . . . . . . take the square root
x = 3 ± 0.5 = {2.5, 3.5}
The total area is 30.25 cm² for x = 2.5 or x = 3.5.

What is a loop describe its function and importance?
A loop is a programming construct that allows a set of instructions to be repeated until a certain condition is met.
What is function?Function is a relation between input and output values, where each input is related to exactly one output. A function is a mathematical rule that assigns a unique output to each input. It is a process that produces a specific result from given inputs. Functions are used in many areas of mathematics, including algebra, calculus and geometry.
The loop can be used to execute a set of instructions multiple times, or it can be used to iterate over a collection of items such as an array. Loops are an important part of programming, as they allow for efficient and concise code.
Loops are especially useful when it comes to dealing with large datasets. For example, if you wanted to loop through an array of 100 elements, you could do so by writing a single loop statement. This allows you to quickly and easily process large amounts of data without having to write separate instructions for each element. Similarly, loops can be used to iterate over a collection of items such as a linked list or a hash table, making it easier to deal with complex data structures.

What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find the inverse function f⁻¹(x) for f(x) = 5x, we can use the following steps:
Replace f(x) with y: y = 5xSwap x and y: x = 5ySolve for y: y = x/5Therefore, the inverse function of f(x) = 5x is f⁻¹(x) = x/5.

How do you dilate from 2cm to 10cm?
Drawing 2 cm 5 times in a straight line will give us a 10 cm line segment after dilation.
What is Dilation ?Dilation is the process of increasing an object's size without altering its form. Depending on the scale factor, the object's size may rise or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's form doesn't change.
A dilation is a function f from a metric space M into itself that, for any locations x, y in M, fulfills the identity d=rd, where d is the distance between x and y and r is a positive real integer. Such a dilatation is a resemblance of the space in Euclidean space.
Meaning of Dilation in Math. Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size.
To dilate 2 cm to 10 cm we need to scale 2 cm 5 times

What is proportion?
In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
Neena counts 11 beats in 5 seconds
So, x=11 and y=5
Using the proportionality
y = k x
k= y/x
k= 11/5
k= 2.2
Hence, the proportional relation is y= 2.2x
Answer:
2.2
Step-by-step explanation:
1. COP= constant of proportionality
What does that mean? This is how much of something you need for the variables to be proportional no matter their value. For example, if you pay 1.99 for 1 gallon of gas but then 30 dollars for 2 gallons at the same gas station, it doesn't make sense. You need to pay $3 for 2 gallons, and so on.
2. How do we find COP?
K is going to represent the constant of proportionality (COP), what we are solving for. Your equation should be k=b/a.
3. B is what comes first in the ratio, and is second. They said "beats to minutes" so beats= b and minutes= a
3. Solve: 11/5= 2.2

The fuel remain after the 9th hour is 48,000 pounds. The result is obtained by subtracting the amount of fuel consumed by four engines for 8 hours from the amount of fuel after the first hour.
How to count the fuel remain?A simple way to count the fuel remain is subtracting the amount of fuel consumed from the amount of initial fuel.
We have
160,000 pounds of fuel after the 1st hour of flight.Fuel consumed for 4 engines = 14,000 pounds per hour.Find the fuel remain after the 9th hour of flight!
From 1st hour to 9th hour of flight, the time duration is
= 9 - 1
= 8 hours
The fuel remain would be
= 160,000 pounds - (14,000 pounds /hour × 8 hours)
= 160,000 pounds - 112,000 pounds

AutoCAD uses two different coordinate systems. Your working plane's angle is determined by the World Coordinate System (WCS) and User Coordinate System (UCS).
In order to guarantee that everything lines up with the center of a file in a real-world location, the WCS should always be utilized as the geometry reference. The screen can be oriented to a location using the UCS. The file originated from the WCS. The WCS can't be moved from its current location.
Drawing elements will use the rotating coordinate system if a user coordinate system is set, however, the WCS can always be changed. A "User Coordinate System" (UCS) specifies the angle of the XY plane in which you are operating. The XY plane is rotated when a user coordinate system is defined, making it easier to work with alternative orientations.
