What is numerical coefficient in 3xy?
The numerical coefficient in 3xy is 3.
In algebraic expressions, terms are made up of coefficients and variables. A coefficient is a numerical value that multiplies a variable or a set of variables. In the term 3xy, the numerical coefficient is the number that appears in front of the variable (x and y) and it's 3 in this case.
It is used to indicate the degree of the term or the number of times the variable is present in the term. In this case, it is indicating that the variable x and y are present three times in the term.
It's important to note that if there is no coefficient before the variable, it is assumed to be 1. It's also noteworthy that the coefficient can be a whole number, a fraction, or even a variable, but in this case it is a whole number. Understanding the concept of coefficient is very important in understanding algebraic equations and expressions.

What is a minimum of 3 examples of polynomials?
Answer:
4x + 3
10x² - 7x + 3
18x² - x + 5
Step-by-step explanation:
A polynomial must consist of 2 terms, one with a variable ( x ) and one as a constant ( any number )
An example of a number with a variable is 4x
An example of a constant is 3
add the two together 4x + 3 and you get a polynomial
More examples are 5x + 9 or -2x - 8
Polynomials can have more than 2 terms. ( the third term has an exponent and variable )
An example of a polynomial with more than 2 terms is 10x² - 7x + 3

Find the ratio of the volume of the cone to the volume of the cylinder. Express your answer as a common fraction.
The ratio of the volume of the cone to the cylinder is 1:3.
A cone has a circular base and the base is made of a radius and diameter.
The volume of a cone is defined as the amount of space a cone occupies. The formula of the volume of a cone is given as one-third the product of the area of the circular base and the height of the cone. If the radius of the cone is "r" and the height is "h", the volume of a cone is given as V = (1/3)πr²h.A cylinder is a three-dimensional solid shape that makes of two parallel bases linked by a curved surface.
Thus, the volume (V1) of a right circular cylinder, using the above formula, is,V1= πr²h
Here,
'r' is the radius of the cylinder
'h' is the height of the cylinder
π is a constant whose value is 22/7.
The ratio of the volume of the cone to the cylinder is
= (1/3)πr²h : πr²h
= 1 : 3
So, the ratio is - 1:3.

An equation written in form: [tex]y=mx + b[/tex] has the slope:
[tex]m \to slope[/tex]
So, in both equations:
[tex]m_1 = -\frac{2}{5}[/tex]
[tex]m_2 = \frac{2}{5}[/tex]
For both lines to be parallel
[tex]m_1 = m_2[/tex]
This is false in this case, because:
[tex]-\frac{2}{5} \ne \frac{2}{5}[/tex]
For both lines to be perpendicular
[tex]m_1 * m_2 = -1[/tex]
This is false in this case, because:
[tex]-\frac{2}{5} * \frac{2}{5} \ne -1[/tex]
(b)
[tex]5y + 2x = -10[/tex]
and
[tex]-5x + 2y = 4[/tex]
Write equations in form: [tex]y=mx + b[/tex]
[tex]5y + 2x = -10[/tex]
[tex]5y = -2x +10[/tex]
Divide by 5
[tex]y = -\frac{2}{5}x +2[/tex]
[tex]-5x + 2y = 4[/tex]
[tex]2y = 5x + 4[/tex]
Divide by 2
[tex]y = \frac{5}{2}x + 2[/tex]
In both equations:
[tex]m_1 = -\frac{2}{5}[/tex]
[tex]m_2 = \frac{5}{2}[/tex]
For both lines to be parallel
[tex]m_1 = m_2[/tex]
This is false in this case, because:
[tex]-\frac{2}{5} \ne \frac{5}{2}[/tex]
For both lines to be perpendicular
[tex]m_1 * m_2 = -1[/tex]
This is true in this case, because:
[tex]-\frac{2}{5} * \frac{5}{2} = -1[/tex]

a. What are the coordinates of the fourth vertex of the rectangle?
b. What are the dimensions of the rectangle?
c. What is the area of the rectangle?
Answer:
Step-by-step explanation:
the two diagonals of a rectangle have the same middle point
middle point
x = (2-4)/2 = -1
y = (1+4)/2 = 5/2
The diagonal BD must have the same middle point, so we can find vertex D in this way
(x +2)/2 = -1
x+2 = -2
x = -4
(y+4)/2 = 5/2
y+4 = 5
y = 1
fourth vertex : (-4, 1)
2) for find the first dimension we can use this formula
|y2 - y1| = |4-1| = 3
for find the second we can use this one:
|x2-x1| = |-4-2| = |-6| = 6 (a dimension can’t be negative)

Is Avogadro's number equal to one mole?
One mole consists of 6.02214076×10²³ units which is Avogadro's number. Thus one mole is known as Avogadro's number.
What is one mole?
A mole is 6.02214076×10²³ of any chemical unit, including atoms, molecules, ions, and others. Due to the large number of atoms, molecules, or other components that make up any substance, the mole is a useful measure to utilize. The mole was initially defined as the quantity of atoms contained in 12 grammes of carbon-12, but the General Conference on Weights and Measures declared in 2018 that the mole will only contain 6.02214076×10²³ of some chemical unit as of May 20, 2019.
In chemistry, a mole, sometimes spelled mol, is a common scientific measurement unit for significant amounts of very small objects like atoms, molecules, or other predetermined particles.

Answer: 108° ; 165°
Step-by-step explanation:
180(n - 2) is the formula to figure out the total degrees in a polygon.
A pentagon has 5 sides, so:
180(5-2) = 180(3) = 540°
Divide the total degrees by the number of angles (a pentagon has 5 angles):
540° ÷ 5 = 108°
24-gon:
180(24 - 2) = 180(22) = 3960°
3960° ÷ 24 = 165°
Answer: 108° ; 165°
Step-by-step explanation:
180(n - 2) is the formula to figure out the total degrees in a polygon.
A pentagon has 5 sides, so:
180(5-2) = 180(3) = 540°
Divide the total degrees by the number of angles (a pentagon has 5 angles):
540° ÷ 5 = 108°
24-gon:
180(24 - 2) = 180(22) = 3960°
3960° ÷ 24 = 165°
What is == and === in Python?
The == operator determines if two operands are equivalent in terms of value. The === operator determines if two operands are equivalent in terms of value and datatype.
The assignment operator = is straightforward. The left side operand receives values from the right side operands.
On the other hand, == determines whether or not the values of two operands are equal.
The Python is operator determines if two variables point to the same memory item as opposed to the == operator, which compares the value or equality of two objects. This implies that you should almost always employ the equality operators == and != Difference between == and = in Python.
A single equal sign is used to assign a value to a variable in Python and many other programming languages, whereas two successive equal signs are used to determine if two expressions provide the same result.

Let represent _______________________________________________.
2. Explain why the inequality sign ≤ makes sense in this context.
3. Graph the inequality 3 + 4 ≤20.
4.The ordered pair (3, −4) is a solution to the inequality 3 + 4 ≤ 20.
Explain why
this is not a viable solution in the context of buying grapes and apples.
5. The ordered pair (4, 2) is a point on the boundary line. Explain what the ordered
pair represents in the situation.
Therefore , the solution to the given problem of inequality comes out to be Part a:where x is the no of apples and y is the no of grapes , Part b:Inequality sign and Part c: ordered pair (3, −4) isn't solution.
What is inequality, exactly?An unbalanced connection between two expressions or values is referred to in mathematics as an inequality. So, inequity results from imbalance. In mathematics, an inequality defines the connection between two non-equal quantities. Egality and inequality do not mean the same thing. Use the not equal sign whenever two values are not equal (). It is possible to compare values of any size using a variety of inequalities. By changing both sides until only the variables are left, it is possible to solve many straightforward inequality problems.
Here,
Given : 3x + 4y ≤ 20.
where x is the no of apples
and y is the no of grapes
Thus,
Part a:
where x is the no of apples
and y is the no of grapes
Part b:
Inequality signs means that 20 will be the maximum amount of the no of apples and no of grapes summation.
Part c: ordered pair (3, −4)
Thus,
putting in the inequality we find:
=> 3(-3)+ 4(-4)
=> -6 -16
=> -22
Thus , it is not a solution for inequality.
Therefore , the solution to the given problem of inequality comes out to be Part a:where x is the no of apples and y is the no of grapes , Part b:Inequality sign and Part c: ordered pair (3, −4) isn't solution.
