Answer:
26 gallons
Step-by-step explanation:
Set up an equation to represent this problem. Parameter (x) represents the gas tank when it is filled. Based on the problem;
[tex]\frac{1}{5}x + 13 = \frac{7}{10}x[/tex]
Inverse operations;
[tex]\frac{1}{5}x + 13 = \frac{7}{10}x\\-\frac{1}{5}x\\\\13 = \frac{7}{10}x - \frac{1}{5}x\\\\[/tex]
Convert to combine denominator, and simplify,
[tex]13 = \frac{7}{10}x - \frac{1}{5}x\\\\13 = \frac{7}{10}x - \frac{2}{10}x\\\\13 = \frac{5}{10}x\\\\13 = \frac{1}{2}x[/tex]
Inverse operations,
[tex]13 = \frac{1}{2}x\\*2\\\\26 = x[/tex]

At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?
Answer:
Kirby Middle School
The percentage of students who used Snap the most is given as:
= 44%
Step-by-step explanation:
a) Data and Calculations:
App Number of Students
Face 8
Snap 22
Insta 20
Total 50
The percentage of Snap users = Number of Snap users/Total users * 100
= 22/50 * 100 = 44%
b) This represents the proportion of all the students surveyed about the use of social media app. Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap. This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.

Which image is a reflection over the line y = x of triangle 1?
Answer:
A edge 2021
Step-by-step explanation:
The correct answer is option A
What is a reflection?Reflection is the mirror image of the shape. In other words reflection is also called a flip.
How to find which triangle which triangle is the reflection of triangle 1 over the line y=x?If a triangle is reflected over the line y=x, then the coordinates of the vertices of the triangle gets interchanged.In the given figure the vertices of the triangle are (1,1) , (4,1) and ( 4,3)
So, after reflection over the line y=x,
The vertices of the triangle will be (1,1) , ( 1,4) and (3,4). Clearly, the triangle will be in the first quadrant itselfSo, the correct answer will be option A , where the triangle has the vertices (1,1) , ( 1,4) and (3,4).
In other options the triangles are not even in the first quadrant.Find out more about 'Reflection' here: https://brainly.com/question/20903710

Answer:
Step-by-step explanation:
The problem here is that the question is not clear. In particular, what does "2)" mean?
Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.

If the x-value repeats and the y does not, is it a function?
Answer:
If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.
For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats
a function because no x value is repeating the x value is known as an independent value. Does that make sense?
"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.
For a relation to be called a function, the following holds true:
Each x-value (input) has it's own unique y-value (output).
A x-value cannot give two different y-values.
If an x-value repeats, the corresponding y-value must repeat.
Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

Answer:
6 Batches because if each batch calls for 1/3 of a cup of flour and you split 2 cups into 1/3 cups you would have 6 1/3 cups
Step-by-step explanation:
Jordan can make 7.111 batches before 3 PM today.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Jordan uses a recipe to make yogurt putty.
He buys a bag of cornstarch containing 128 servings that are 1/8 cups each.
He needs [tex]2\frac{1}{4}[/tex] cups for each batch of yogurt putty.
So, servings are 128 x (1/8)
