a = a is an example of which algebraic property (A) Symmetric property (B) transitive property (C) reflexive property (D) commutative property of multiplication
Answer:
(C) reflexive property
Step-by-step explanation:
In algebra there are several rules and properties that help us work and discover new things, the reflexive property of algebra states that every single thing is equal to itslef, this means that you can use any term, let´s say "w", and "w" will always be equal to itself. W=W, just as a=a.

what percent of 92 is 69
The number 69 is 75 % or 75 percentage of the number 92
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage be represented as A
Let the first number be n₁ = 92
Let the second number be n₂ = 69
And , the percentage value of 69 of the number 92 is given by
n₂ = ( A / 100 ) x 92
On simplifying , we get
69 = ( A / 100 ) x 92
Multiply by 100 on both sides , we get
6900 = 92A
Divide by 92 on both sides , we get
A = 6900 / 92
A = 75 %
Therefore , the value of A is 75 %
Hence , the percentage value of 69 of the number 92 is 75 %

Last week, there were 225 student absences at Johnson High. The circle graph below summarizes them by the day of the week on which they occurred. The central angle for the Tuesday slice is 86.4° . What percentage of the absences occurred on Tuesday?
The percentage of student absences that occurred on Tuesday is approximately 24%.
The circle graph represents the distribution of student absences by day of the week. The central angle for the Tuesday slice is given as 86.4°. To find the percentage of absences on Tuesday, we use the formula: (Central Angle / Total Central Angle) * 100%. In this case, (86.4° / 360°) * 100% ≈ 24%. Therefore, approximately 24% of the student absences occurred on Tuesday.
The central angle represents the proportion of the total absences attributed to each day. A circle has a total central angle of 360°, and the central angle for each day is a fraction of this total. Tuesday's central angle of 86.4° indicates that Tuesday's absences make up 24% of the total absences.
This method applies because the circle graph represents a whole, and each sector's central angle corresponds to its share of the total. Consequently, the calculation accurately reflects the percentage of absences on Tuesday in relation to the entire week.

A. Multiplication comes before division because in PEMDAS the M comes before D.
Students who use PEMDAS often think that multiplication must come before division but that's not necessarily the case. If division appears before multiplication when your reading the problem from left to right, do your division first and then move on to your multiplication.

The solution of the expression [tex]7\dfrac{1}{5}[/tex] which is in the mixed fraction as a decimal form is 7.2.
The combination of a whole number and a proper fraction is called as mixed fraction.
The solution of the expression [tex]7\dfrac{1}{5}[/tex] as a decimal is calculated as:
First, convert the given mixed fraction into the improper fraction.
[tex]7\dfrac{1}{5} =\dfrac{(7 \times 5)+1}{5}[/tex]
On further solving,
[tex]\dfrac{(7 \times 5)+1}{5} = \dfrac{36}{5}[/tex]
The improper fraction is converted into the decimal by dividing 36 by 5,
which results to 7.2.
The solution of the expression [tex]7\dfrac{1}{5}[/tex] as a decimal, is 7.2.

Which of the following sets of numbers is a Pythagorean triple?
A) 42, 40, 82
B) 42, 40, 58
C) 41, 41, 58
D) 40, 41, 57
Answer with explanation:
1.⇒Area of Parallelogram = Corresponding height × Base
= 2 cm × 18 mm
→1 cm = 10 mm
So, Area of Parallelogram
= 2 cm × 1.8 cm
= 3.6 cm²
Option C: →3.6 cm²
→→→2. A triplet ,that is set of three numbers is called Pythagorean triplet, if it is of the form of : {m²-1, 2 m , m²+1}
That is if you write the Pythagorean rule for Right triangle, having sides , m²-1, 2 m , m²+1
then ,→ Square of Largest side = Sum of squares of two smallest side
Square of Largest Side = (m²+1)²
Sum of squares of two smallest side= (2 m)² + (m²-1)²
= 4 m² + (m²)² -2 m²+1
= (m²)² +2 m²+1
=(m²+1)²
So, we will check out , out of four options which of them are Pythagorean Triplet.
Option 1.
Square of Largest Number = 82²=6724
Sum of squares of two smaller number= 42² + 40²
= 1764 +1600
= 3364
→Square of Largest Number ≠Sum of squares of two smaller number
6724 ≠ 3364
Not a Pythagorean Triple.
Option 2.
Square of Largest Number = 58²=3364
Sum of squares of two smaller number= 42² + 40²
= 1764 +1600
= 3364
→Square of Largest Number =Sum of squares of two smaller number
3364= 3364
A Pythagorean Triple.
Option 3.
Square of Largest Number = 58²=3364
Sum of squares of two smaller number= 41² + 41²
= 1681 +1681
= 3362
→Square of Largest Number ≠Sum of squares of two smaller number
3364 ≠ 3362
Not a Pythagorean Triple.
Option 4.
Square of Largest Number = 57²=3249
Sum of squares of two smaller number= 41² + 40²
= 1681 +1600
= 3281
→Square of Largest Number ≠Sum of squares of two smaller number
3249 ≠ 3281
Not a Pythagorean Triple.
Option B: (42, 40,58) is a Pythagorean triple.

You need to arrange four of your favorite books along a small shelf. How many different ways can you arrange the books assuming the order of the books make a difference
Final answer:
To determine the number of different arrangements of four books, we calculate the permutation 4!, which equals 24. Hence, there are 24 different ways to arrange the four books.
Explanation:
The question asks about the number of different ways to arrange four books on a shelf, assuming the order of the books makes a difference. This problem is an example of a permutation, where the arrangement of a set of items is important.
To calculate this, we use the formula for permutations, which is n!, where 'n' is the number of items to arrange. In this case, we have four books, so we calculate 4! (which is shorthand for 4 × 3 × 2 × 1).
Therefore, 4! = 24. There are 24 different ways to arrange the four books on the shelf.
