The number of students would there be in a school with 32 teachers is 32k.
What is meant by proportionality?In general, proportion refers to a part, share, or amount considered in comparison to a whole. According to the definition of proportion, two ratios are in proportion when they are equivalent. It is a formula or statement that shows that two ratios as well as fractions are equal.A proportion formula is just an equation that may be solved to determine the values to compare. We use the concept of proportion to solve proportion problems, which is two ratios that really are equal to each other.As the number of students are proportional to number of teachers.
Thus,
students ∝ teachers
student ∝ 32
students = 32k
where, k is the constant of proportionality.
Thus, the total number of students will be 32 k.

The algebraic solution for the variable x is as follows:
x = 9 / 2. How to find the variable x in the equation?The equation is represented as follows;
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
open the bracket on the left side
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
Add 1 /3 x to both sides
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 + 1 / 3 x = - 1 / 3 x + 1 / 3 x + 1 / 2
4 / 5 + 1 / 3 x - 2 / 5 x = 1 / 2
4 / 5 + 5x - 6x / 15 = 1 / 2
4 / 5 - x / 15 = 1 / 2
subtract 4 / 5 from both sides
4 / 5 - 4 / 5 - x / 15 = 1 / 2 - 4 / 5
- x / 15 = 5 - 8 / 10
- x / 15 = - 3 / 10
cross multiply
- x / 15 = - 3 / 10
-10x = - 45
divide both sides by -10
x = 45 /10
x = 9 / 2
Therefore, the algebraic solution for the variable x is 9 / 2.

Identify the angle relationship and find the measure of the indicated angle.
(Alternate Interior, Alternate Exterior, Corresponding, Same-side Interior)
The angled relationship is the Same-side interior angle where x is 6 and ∠EFG is 102°
For the parallel lines ED and FG, where EF is the transversal,
The angle DEF and the angle EFG are same-side interior angles.
By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).
∠DEF = 13x°
∠EFG = 17x°
∠DEF + ∠EFG = 180°
13x + 17x = 180
30x = 180
x = 6
∠DEF = 13x = 13*6 = 78°
∠EFG = 17x = 17*6 = 102°
Therefore, the angles follow the same-side interior angles relationship, x = 6 and ∠EFG = 102°

The sum of two numbers is 14 . One number is 2 less than the other. Find the numbers.
The two numbers are 6 and 8.
What are the two numbers?The first step is to determine the simultaneous equations that would be used to determine the answer. The simultaneous equations would be derived from the information provided in the question.
x + y = 14 equation 1
x - y = 2 equation 2

Determin whether the relation defines a function, and give the domain and range.
The relation is not a function if its domain is on the x-axis and its range is on the y-axis. However, if the relation's domain is on the y-axis and its range is on the x-axis, it is a function.
If so, what kind of function is it?
Relationships are defined by three factors:
1. domain is a set of inputs.
2. an output set referred to as range.
3 . relationships between domain and range-related items.
If and only if each element of the domain is associated to just one member of the range, is a relation a function. It must be noted that the solution may vary based on the domain and range that we assume.
The provided relation is a function if the x-axis is the range and the y-axis is the domain, as opposed to when the x-axis is the domain and the y-axis is the range.

Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:
Let us assume, the width of the rectangle be 'w' inches
The length of a rectangle be (9w - 11)
As we know, perimeter of a rectangle is 2(l + w)
Substitute the calculated parameters in the perimeter formula:
18 = 2(9w - 11 + w)
⇒ 9 + 11 =10w
⇒ w = 2 inches and l = 7 inches
Then, the calculated width is 2 inches and length is 7 inches.

Step-by-step explanation:
Teresa has a total of 13 coins.
None of them are pennies, and she has at least three each of quarters, dimes, and nickels.
What is the least amount of money she can have?
Answer: $0.65
Step-by-step explanation:
She can have all nickels since at least 3 nickels means that there is a possibility that all 13 of her coins are nickels.
100 cents=1 dollar
Nickel=5 cents
5 cents * 1 dollar/100 cents=
5*1/100=0.05 dollars
Hence, the least total amount of money she could have is:
13*0.05=$0.65
This is equivalent to 140 cents.
==========================================================
Explanation:
"she has at least three each of quarters, dimes, and nickels"
Let's say she has exactly 3 of each for now
3 quarters = 3*25 = 75 cents3 dimes = 3*10 = 30 cents3 nickels = 3*5 = 15 centsSo far she has 75+30+15 = 120 cents (aka $1.20) with the 3*3 = 9 coins mentioned. There are 13-9 = 4 coins remaining
To achieve the least money possible, those missing four coins must be the smallest denomination allowed, i.e. the nickel. We can't go for penny since it states "none of them are pennies". So we add 4*5 = 20 more cents onto 120 to get 120+20 = 140 cents aka $1.40
If α =i+j−2k, β =−i+2j+3k andγ =5i+8k, then find c and d such that γ−cα−dβ is perpendicular to both α and β
If [tex]\hat\gamma-c\hat\alpha-d\hat\beta[/tex] is perpendicular to both [tex]\hat\alpha[/tex] and [tex]\hat\beta[/tex], then their dot products are zero.
Recall that for any vector [tex]\hat x[/tex], [tex]\hat x\cdot \hat x = \|\hat x\|^2[/tex].
Now, we have
[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\alpha = (\hat\gamma\cdot\hat\alpha) - c\|\hat\alpha\|^2 - d (\hat\beta\cdot\hat\alpha) = 0[/tex]
[tex]\hat\gamma\cdot\hat\alpha = 5 + 0 - 16 = -11[/tex]
[tex]\|\hat\alpha\|^2 = 1^2 + 1^2 + (-2)^2 = 6[/tex]
[tex]\hat\beta\cdot\hat\alpha = -1 + 2 - 6 = -5[/tex]
[tex]\implies 6c - 5d = -11[/tex]
and
[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\beta = (\hat\gamma\cdot\hat\beta) - c(\hat\alpha\cdot\hat\beta) - d \|\hat\beta\|^2 = 0[/tex]
[tex]\hat\gamma\cdot\hat\beta = -5 + 0 + 24 = 19[/tex]
[tex]\|\hat\beta\|^2 = (-1)^2 + 2^2 + 3^2 = 14[/tex]
[tex]\implies 5c - 14d = -19[/tex]
Solve for [tex]c[/tex] and [tex]d[/tex]. By elimination,
