120% is considered an enlargement since the scale factor is greater than one.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.
It is considered a reduction of the scale factor is less than one, and an enlargement if the scale factor is greater than one.

Symmetric property of congruence
ANSWER its one question
Answer:
x = 12, y = 60
Step-by-step explanation:
We have parallel lines, so alternate interior angles are congruent.
6x + 3 = 75
6x = 72
x = 12
The interior angles of a triangle add up to 180 degrees.
45 + 75 + y = 180
120 + y = 180

The Inverse Function Line Test
A given graph represents a function only if for every value of x there is only one corresponding value of y.
This can be checked by using a vertical line and moving it through the x-axis. If that line intersects the graph more than once, then the graph does not correspond to a function.
The image shows a graph and if we move our imaginary vertical line from x=-2 to x=7 that line would intersect the graph only once. This means that the graph corresponds to a function in the domain [-2,7].
For the inverse function to exist, the horizontal line test must be passed.
Imagine a horizontal line moving through the y-axis. It would intersect the graph only once from y=0 to y=6.
We can conclude this graph corresponds to a function and it has an inverse function because it passed the horizontal line test.

farm b has a 200 ft well that uses 10000 cubic feet of natural gas per year. if the cost of natural gas is the same a farm a, what is the annual cost to operate this well
Annual cost to operate farm B well with cost of natural gas $2.50 per 1,000 cubic feet and uses of 10000cubic feet of natural gas per year is $25.
As given,
Farm A:
Cost of natural gas per 1,000 cubic feet=$2.50
Farm B:
Uses of natural gas per year = 10000cubic feet
Cost of natural gas of farm B is same as farm A
Cost of natural gas per 1,000 cubic feet=$2.50
⇒1cubic feet=2.50/1000
Annual cost to operate 200ft well that uses 10000 cubic feet natural gas
10000 cubic feet=(2.50 ×10000)/1000
=$25
Therefore, annual cost to operate farm B well with cost of natural gas $2.50 per 1,000 cubic feet and uses of 10000cubic feet of natural gas per year is $25.
The complete question is:
Farm A has a 100 ft well that uses 7,000 cubic feet of natural gas per year. If the cost of natural gas for farm A is $2.50 per 1,000 cubic feet.

Which method describes an observational study? Method 1 is an observational study because past data are collected and analyzed. Method 2 is an observational study because two city schools are chosen to participate. Method 2 is an observational study because students can choose to participate in the music lessons. Both methods are observational studies because both include students who do and do not play a musical instrument.
Both methods are observational studies because both include students who do and do not play a musical instrument. So, this method describes an observational study.
Several various kinds of non-experimental studies in which behavior is routinely observed and documented are together referred to as observational research. A variable or combination of variables must be described in order to be the focus of observational research.
In a broader sense, the objective is to capture a moment in time of certain traits of a person, group, or environment. We cannot draw causal inferences from observational research since nothing is altered or controlled, as previously said, making it non-experimental. Although they may also be quantitative or both, the data that are gathered in observational research investigations are frequently qualitative in nature (mixed-methods).

Answer:
IF ITS THIS QUESTION
An article in a psychology journal claims that young students who play a musical instrument tend to have higher test scores on state math exams. To assess the claim, a government official considers two methods to collect data.
Method 1: Contact many city schools and ask them to provide summary data on state math exam performance and students who participate in music lessons.
Method 2: Choose two city schools and provide free music lessons to students who register. At the end of the year, compare state math exam scores for students who participated in the music lessons with the scores for those who did not.
Step-by-step explanation:
THE AWNSER IS C
Method 2 is an observational study because students can choose to participate in the music lessons.
An observational study is a type of research in which researchers observe and record the behavior of a group of individuals, but do not manipulate or intervene in any way. In this case, Method 2 describes an observational study because the researchers are not manipulating the students' participation in music lessons. Instead, the students are free to choose whether or not to participate in the music lessons, and the researchers simply observe and record the state math exam scores for both groups of students. In contrast, Method 1 is not an observational study because it involves collecting summary data on state math exam performance and music lesson participation, rather than observing and recording the behavior of the students.

What is the sum of two supplementary angles?
Two angles are referred to as supplementary angles if their combined value is 180°. A straight angle is created when supplementary angles are combined (180°).
In other words, ∡A and ∡B are supplementary if ∡A plus ∡B equals 180°. Angles A and B are described as "supplements" of one another in this context.
In math, A° + B° = 180°.
Given, m∡RJI = 12x - 3, m∡KJR = 6x - 5, m∡KJI = 172°
As seen from diagram, m∡RJI + m∡KJR = m∡KJI
⇒ (12x-3)+(6x-50) = 172° ⇒ 18x - 53 = 172° ⇒ x = ([172 + 53]/18)° = 12.5°
Therefore, the value of x = 12.5°
Thus, m∡KJR = 6x - 5 = (6*12.5) - 5 = 69°

[tex]y = ab^{\frac{x}{n}}[/tex]
In which:
a is the initial value.b is the rate of change.n is the period of the change of change.Considering that the pool has 1500 gallons, and drains 3% every 5 minutes, the parameters of the function are given as follows:
a = 1500, b = 1 - 0.03 = 0.97, n = 5.
Hence the amount of water in the poll after x minutes is given by:
[tex]y = 1500(0.97)^{\frac{x}{5}}[/tex]
After 50 minutes, the amount of water in the pool is:
[tex]y = 1500(0.97)^{\frac{50}{5}} = 1500(0.97)^{10} = 1106[/tex]
1106 gallons.
The poll will have less than 1000 gallons when:
y = 1000 (we can use it because the function decreases continuously).
Hence:
[tex]1500(0.97)^{\frac{x}{5}} = 1000[/tex]
[tex](0.97)^{\frac{x}{5}} = \frac{1000}{1500}[/tex]

A scientist needs 1.8 liters of a 22% alcohol solution. She has available a 33% and a
17% solution. How many liters of the 23% and how many liters of the 17%
solutions should she mix to make the 22% solution?
Step-by-step explanation:
the approach of the other answer is basically correct, but we need to use the correct numbers.
so, I assume that the 33% of the first solution is correct, and not the 23% mentioned later.
x = liters of the 33% solution.
y = liters of the 17% solution.
we know that
x + y = 1.8
and therefore
x = 1.8 - y
and then we want to enforce the desired result (ab% are simply 0.ab)
0.33x + 0.17y = 0.22×1.8
we use the identity from above in this equation :
0.33(1.8 - y) + 0.17y = 0.396
0.594 - 0.33y + 0.17y = 0.396
0.198 - 0.16y = 0
0.198 = 0.16y
y = 1.2375 liters
x = 1.8 - y = 1.8 - 1.2375 = 0.5625 liters
if the first solution is truly only 23%, then we only need to change the number :
0.23(1.8 - y) + 0.17y = 0.396
0.414 - 0.23y + 0.17y = 0.396
0.018 - 0.06y = 0
0.018 = 0.06y
y = 0.3 liters
x = 1.8 - y = 1.8 - 0.3 = 1.5 liters
