The amount that you would tip someone if the total cost of the meal is 13.40$ is: $2.01.
How much is the standard tip in the United States?In the United States, the standard tip for good service is 15%. So, assuming that the meal service offered could be classified as a good service, we can say that 15% of 13.40$ will be the tip to provide.
15% of 13.40$ is equal to $2.01.
Therefore, the amount that the person who received the service is expected to pay is $2.01. Also, note that the tip for delayed service is 10% and the tip for excellent service is 20%. Bad service requires no tip.

What is defined by the term transformation?A transformation is a method of modifying a polygon or even other two-dimensional element on a plane as well as coordinate system. Two-dimensional figures keep moving around a plane as well as coordinate system using mathematical transformations.A preimage, also known as an inverse image, is the this double shape that exists before any transformation. The estimate after transformation is depicted in the image.For the given question;
DE segment length is 5 cm.
The transformation implemented to DE now is; Rx degrees R₀.-270 degrees.
That is, DE is the segment.
270° counter-clockwise rotation about the origin, then reflected across the x-axis
It is necessary to determine the length of a segment that is the image of DE.
Because, as we all know,
The only transformation that affects the figure's measurements is 'dilation.'
As a result, rotation and reflection have no effect on the shape and size of a segment DE.
Therefore, the image of DE will have the same length as DE, i.e. 5 cm.

How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, Total number of water bottles bought = 4
Total number of people sharing the bottles = 5
Since each bottle is divided in equal portion, each portion of bottle = 1/5
Also, Sarah took one portion from each of the four bottles, thus
Sarah has portion of water = 4*(1/5) = 4/5
Sarah has taken 4/5 portion of the available water bottles.

How are internal and exterior angles distinguished?
The external angle is the angle formed by any side of an object and a line that runs from another side.
An interior angle is the shape that results from joining the two rays at their terminal. An internal angle is the angle inside a shape. A polygon is a closed shape with sides and vertices.
If this angle is one, the total exterior angle is 360 degrees.
and if the angle is inside, enter 180 degrees.
I'm taking this given angles i.e, (7x+7)° and (2x+2)° as an exterior angle to solve for x.
Now, (7x+7)° + (2x+2)° = 360°
7x + 7 + 2x + 2 = 360°
9x + 9 = 360°
9(x + 1) = 360
x + 1 = 360 / 9
x + 1 = 40
x = 39
We get x = 39, now put these x value to find the angle
(7x+7)° | (2x+2)°
(7 * 39 + 7)° | (2 * 39 + 2)°
280° | 80°

Liters of 10% acid solution and liters of 70% acid solution
Let
x -----> number of liters of 10% acid solution
y ----> number of liters of 70% acid solution
so
we have that
x+y=90 ------> x=90-y -----> equation 1
Remember that
10%=10/100=0.10
70%=70/100=0.70
20%=20/100=0.20
so
0.10x+0.70y=0.20(90) ------> equation 2
Solve the system of equations
substitute equation 1 in equation 2
0.10(90-y)+0.70y=0.20(90)
solve for y
9-0.10y+0.70y=18
0.60y=18-9
0.60y=9
y=15
Find out the value of x
x=90-y

use similar triangles to calculate the height h cm of triangale abe
The height of ∆EBA is 24cm in the given question where two triangles are similar.
What are similar triangles?Similar triangles are triangles that have the same shape but differ in size. Similar objects include all equilateral triangles and squares with any side length. In other words, if two triangles are similar, their corresponding angles and sides are congruent and in equal proportion. The " symbol here denotes the similarity of triangles.
We know that in two similar triangles, the ratio of corresponding sides are equal to ratio of their heights.
We have given that ∆DBC ≅ ∆EBA
So,
⇒ (36-h)/h = DC/AE
⇒ (36-h)/h = 10/20
Using cross multiplication
⇒ 20(36-h) = 10h
⇒ 720 - 20h = 10h
⇒ - 20h -10h = -720
⇒ -30h = -720
⇒ 30h = 720
⇒ h = 720/30
⇒ h = 24

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 8 minutes. Find the probability that a randomly selected passenger has a waiting time 2.25 minutes.
Using the uniform distribution, it is discovered that there is a 0.625 = 62.5% chance that a randomly picked passenger will have to wait longer than 2.25 minutes.
The boundaries of a uniform distribution are a and b.
The likelihood of discovering a value greater than x is:
P(X > x) = (b - x)/(b - a)
In this problem, the time is equally distributed between 0 and 6 minutes, so.
a=0
b=6
P(X > 2.25) is the probability of a time larger than 2.25 minutes, so:
P(X > x) = (6 - 2.25)/(6 - 0) = 0.625

What is probability?Generally, If there are a total of 90 people, then the number of people who like comedic films is equal to 90 divided by 6, which is 15.
If there are a total of 180 people, then the number of people who like comedic films is equal to 180 divided by six, which is 30. If there are 270 people in total, then the number of people who like comedic films is equal to 270 divided by six, which is 45.
If there are a total of 360 individuals, then the number of persons who like comedic films is equal to 360 divided by six, which is 60.
Let the x-axis show the total number of persons, and let the y-axis show: The number of persons who like comedic motion pictures are shown along the y-axis.
In conclusion, The following will be the function: f(x) equals six times the total number of persons, where x is the total headcount.
