Which equation and value of & represent this relationship?
Answers
The equation will be written as (42/2) = 21.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the quotient of a number, 2, and 21 is 42. The equation of the quotient will be written as,
42 / 2 = 21

What is inequality?
The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has diverse meanings to different people, it is prone to misunderstanding in public discourse.
It can be found out simply by substituting [tex](x, y)[/tex] values in the given equation
[tex]y < 2 x^2+3 x-5[/tex]
let us start with the point [tex]3(1,8)[/tex]
here [tex]x=1 \text { and } y=8[/tex] therefore [tex]y < 2 x^2+3 x-5[/tex]
[tex]8 < 2\left(1^2\right)+3(1)-5=2+3-5=0[/tex]
that means, [tex]8 < 0[/tex] which is an incorrect inequality, therefore the point
[tex]B(1,8)[/tex] is not a solution of the given inequality.
similarly, for [tex]C(-5,10)[/tex]
[tex]10 < 2(-5)^2+3(-5)-5=50+15-5=60[/tex]
that is [tex]10 < 60[/tex], which is correct.
therefore[tex]C(-5,10)[/tex] is a solution of the given inequality.
next[tex]D(3,6)[/tex]
[tex]6 < 2(3)^2+3(3)-5=18+9-5=22[/tex]
that is[tex]6 < 22[/tex], which is correct . Therefore the point D is a solution of the given inequality.

What is an equation?
In mathematics, an equation is a formula that expresses equality by connecting two expressions with an equal sign. Equations and their cousins in other languages may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, whereas in English any well-formed expression consisting of two expressions joined by an equal sign is an equation.
To solve an equation involving variables, it is necessary to determine which values of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values of the unknowns that satisfy the equation are called the solution of the equation. There are two types of equations: identities and constraints. The ID applies to all values of the variable. Constraint expressions apply only to specific values of variables.

The required inequality that represents the given situation is 35+12C≥100.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Both mathematical phrases, equations, and inequalities are created by connecting two expressions.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >,<, ≥, ≤ or ≠ indicate that the two expressions in inequality are not always equal.
So, initial payment = $35
$12 in additional fees for each class
The minimum goal is $100.
There are C classes in total.
Minimum target: One-time starting charge + (Additional fee per class) x (Number of classes)
The scenario's inequality is as follows:

We will not be able to figure out the price of one can of each type of canned food in the same manner of operating on two equations.
This is because the equation are identical.
How to calculate the price?Let the dog food be represented by d.

Since Carlos buys 4 cans of dog food and 6 cans of cat food for $12.00. This will be:
4d + 6c = 12
This cane b reduced to lowest term as 2d + 3c = 6
Then the next week, he purchased 2 cans of dog food and 3 cans of cat food for $6.00. This will be:

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15.
Out of a randomly selected 3700 people from the population, how many of them
would have an IQ less than 66, to the nearest whole number?
Answers
Since we want to find the number of people with an IQ less than 66, which is less than one standard deviation from the mean, we can use the first part of the rule. We know that 68% of the values fall within one standard deviation of the mean, so we can say that 100% * (1 - 0.68) = 32% of the values fall outside of one standard deviation from the mean.
Since the standard deviation of the IQ scores is 15, we can say that 32% of the values fall below the mean - 15 and above the mean + 15. We can also say that 32% of the values fall below 100 - 15 = 85 and above 100 + 15 = 115.
Therefore, out of the 3700 people selected from the population, we can expect that 32% * 3700 = <<32*.01*3700=1184>>1184 of them will have an IQ less than 85 or greater than 115.
Since we are interested in the number of people with an IQ less than 66, we need to subtract the number of people with an IQ greater than 115 from the total. This means that 1184 - (3700 - 1184) = 1184 - 2516 = <<1184-(3700-1184)=1184-2516=-1332>>-1332 of the people selected will have an IQ less than 66.
Since it is not possible for a person to have a negative IQ score, the number of people with an IQ less than 66 is 0.

From KA-12's perspective, the angle between the UFO and SAL-11 is 60∘. From SAL-11's perspective, the angle between the UFO and KA-12 is 75∘. How far is the UFO from KA-12?
Answers
The distance between UFO and KA-12 is 1229.7 Km
Given,
Satellites KA-12 and SAL-11 have spotted a UFO.
Distance between Satellites KA-12 and SAL-11 = 900 km
Angle between UFO and SAL-11 = 60°
Angle between UFO and KA-12 = 75°
We have to find the distance between UFO and KA-12;
Here,
Consider as a triangle;
Sum of interior angles of a triangle = 180 degree
So,
The third angle here will be = 180 - 60 + 75 = 180 - 135 = 45°
Now, use sin rule;
x / sin 75 = 900 / sin 45
x = sin 75 × 900 / sin 45
x = 900 × 0.966 / 0.707
x = 869.4 / 0.707
x = 1229.7

The value of m∠T in the triangle is 65°
How to find m∠T in the triangle?
The congruence of any two figures is generally understood as two figures which can perfectly overlap each other. Congruent triangles are triangles that are perfect copies of one another.
Given: ΔABC and ΔRST
If the two triangles ABC and RST are arranged, two angles and a side of one are respectively equal to two angles and the corresponding side of the other (AAS). Thus, the triangles are congruent. This implies:
∠A = ∠R, ∠B = ∠S, |AB| = |RS| .Also, ∠C = ∠T, |AC| = |RT| and |BC| = |ST|
Thus, <R = 41°, ∠S = 74°,
<R + ∠S + ∠T = 180° (Sum of angle in a triangle)
41 + 74 + ∠T = 180
115 + ∠T = 180
∠T = 180 - 115
∠T = 65°
Therefore, m∠T = 65°
