The measure of the angles x and z is 95 degrees and 30 degrees after applying the property of interior angles.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
The figure is given in the picture:
From the property of interior angles:
x + 85 = 180
x = 95 degrees
6z - 85 + 85 = 180
z = 180/6
z = 30 degrees
Thus, the measure of the angles x and z is 95 degrees and 30 degrees after applying the property of interior angles.

A variable is a quantity that could change depending on the circumstances of an experiment or mathematical problem. Typically, a variable is denoted by a single letter. The general symbols for variables most frequently used are the letters x, y, and z.
Explain the variables in mathematics?A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
A symbol (typically a letter) used in algebra to represent an unknowable numerical value in an equation. X and Y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s are examples of frequently used variables (arc length).
The price to produce x yearbooks will be 15x.
Additionally, software has a fixed cost of $800.
So the total price would be:

A quadratic function passes through the points (−1,−1), (2,−19), and (3,−33).
What is the equation of the function in standard form?

B) f(x)=−2x^2+4x−3
C) f(x)=−2x^2−4x+3
D) f(x)=−2x^2+4x+3
Answers
The quadratic function has an equation of f(x) = -2x² - 4x - 3
How to determine the equation of the functionFrom the question, the ordered pairs are given as
(−1,−1), (2,−19), and (3,−33).
A quadratic function is represented as
f(x) = ax²+ bx + c
Using the point (-1, -1), we have
a(-1)²+ b(-1) + c = -1
So, we have
a - b + c = -1
Using the point (2, -19), we have
a(2)²+ b(2) + c = -19
So, we have
4a + 2b + c = -19
Using the point (3, -33), we have
a(3)²+ b(3) + c = -33
So, we have
9a + 3b + c = -33
So, we have
a - b + c = -1
4a + 2b + c = -19
9a + 3b + c = -33
Using a graphing tool, we have
a = -2, b = -4 and c = -3
Substitute a = -2, b = -4 and c = -3 in f(x) = ax²+ bx + c
So, we have
f(x) = -2x² - 4x - 3
Hence, the equation is f(x) = -2x² - 4x - 3

Based on the calculations, each missing height of this cylinder is; 6 and 5 inches.
How to calculate the volume of a cylinder?Mathematically, the volume of a cylinder can be calculated by using this formula:
V = πr²h
Where:
V is the volume of a cylinder. h is the height of a cylinder. r is the radius of a cylinder.
Now h the subject of formula, we have:
h = V/πr²
When V = 96π and r = 4, the volume of this cylinder is;
h = V/πr²
h = 96π/π(4)²
h = 96/16
Height, h = 6.
When V = 31.25π and r = 2.5, then the volume of this cylinder is;
h = V/πr²
h = 31.25π/π(2.5)²
h = 31.25/6.25

In the construction of a frequency distribution, the class limits should be made very clear in order for each observation to fall into only one class.
It is not a good idea to have ovelaping class limits like 20-30, 30-40. This is because overlaping limits such as this would make it dificult to determine the class where 30 is located.

The constant of proportionality in the given representation is 3 .
The proportionality constant is the ratio that connects two given numbers in a connection that is thought to be proportional. The proportionate constant is also known as constant ratio, unit rate, variable of variation, and even rate of change.
The proportionality constant is calculated by a proportionality constant illustration.
Finding the proportionality constant begins with identifying the x and y elements. To figure out the weight to stick ratio, x will stand for size and Y for the number of butter sticks. We use the equations k = y/ x to calculate the proportionality constant.
Given the value of x is 4 and the value of y is 12

Step-by-step explanation:
let Sue's age be x then Mary is x + 4 and the sum of their ages is
x + x + 4 = 16
2x + 4 = 16 ( subtract 4 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
x + 4 = 6 + 4 = 10
