Hidemi will receive a tip approximately amount of $13.50 which is the correct answer would be option (C).
Hidemi works as a waiter. He serves a table of four with a bill of $90.27. If Hidemi gets a 15% tip which is given in the equation.
What is the percentage?The percentage is defined as a ratio stated as a fraction of 100.
For example, if Shekharaman received a 57% on his quiz, she received a 67 out of 100. It is written as 57/100 in fractional form and 57:100 in ratio form.
We have to determine the evaluation of 15% of $90.27.
⇒ 15% of 90.27
15% is described as 15/100 in fractional form
⇒ (15/100)(90.27)
15/100 is expressed as 0.15 in decimal form
⇒ (0.15)(90.27)
Apply the multiplication operation, and we get
⇒ 13.540 ≈ 13.50
Therefore, He will receive a tip approximately amount of $13.50.

A family is comparing different car seats. One car seat is designed for a child up to and including 30 lb. Another car seat is designed for a child between 15 lb and 40 lb. A third car seat is designed for a child between 30 lb and 85 lb, inclusive. Model these ranges on a number line. Represent each range of weight using interval notation. Which car seats are appropriate for a 32-lb child?
The interval notation is:
0 < x ≤ 30; 15 < x < 40; 30 ≤ x ≤ 85;
The second and third car seats are suitable.
The number lines shows the weights of the car seats which is designed for in comparison the weight of the 32lb child.
Three car seats are designed as follows:
The car seat made for children upto 30lb. The seat for children between 15lbs and 40lbs andThe seat designed for a child between 30 lb and 85 lbAs the seat designed for a child upto and including 30 lb would not be suitable for 32 lb child. Because 32lb is more than the 30 lb.
Now, the seat designed for a child between 30 lb and 85 lb, 30lbs and 85lbs would be suitable as the child is within these weight ranges that is 32lb.

The m6 = (11x + 8)° and m7 = (12x – 4)° What is the measure of 4? m4 = 40° m4 = 48° m4 = 132° m4 = 140°
The measure of angle 4 is 40°. That is, m4 = 40°. The correct option is the first option m4 = 40°
From the diagram, we can observe that angles 6 and 7 are vertically opposite angles.
From one of the angle theorems, we have that vertically opposite angles are equal
That means,
measure of ∠ 6 = measure of ∠ 7
From the question,
we have that, m6 = (11x + 8)° and m7 = (12x – 4)°
Since, the measures of angles 6 and 7 are equal, then we can write that
(11x + 8)° = (12x – 4)°
Now, determine the value of x, we will solve the equation
11x + 8 = 12x – 4
First, subtract 11x from both sides
11x - 11x + 8 = 12x - 11x - 4
8 = x - 4
Now, add 4 to both sides
8 + 4 = x -4 +4
12 = x
∴ x = 12
Now, we will determine the measure of ∠6
m ∠6 = (11x + 8)°
Put x = 12
∴ m ∠6 = (11(12) + 8)°
m ∠6 = (132 + 8)°
m ∠6 = 140°
To determine the measure of ∠4, m4, we will first determine the measure of ∠8.
From the diagram,
m ∠6 + m ∠8 = 180° (Sum of angles on a straight line)
∴ 140° + m ∠8 = 180°
Then,
m ∠8 = 180° - 140°
m ∠8 = 40°
From the diagram, we can observe that angles 4 and 8 are corresponding angles.
Also, from one of the angle theorems, we have that corresponding angles are equal.
Hence, the measure of ∠ 4 equals the measure of ∠ 8.
From above, m ∠8 = 40°
∴ m ∠4 = 40°
Hence, the measure of angle 4 is 40°. That is, m4 = 40°. The correct option is the first option m4 = 40°

Use two or three unit fractions to convert. 1515 daysdaysequals=_______ secondsseconds
It is found that Fifteen days is equivalent to 1,296,000 seconds, Or we can say one million two hundred ninety-six thousand seconds.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need to find the unit fractions to convert 15 days into seconds.
1 day = 24 hour
1 hour = 60 minutes.
1 minutes = 60 seconds
Therefore, 24 hours = 24 x 60 x 60 = 86400 seconds
There are 86400 seconds in one day.
Then 15 days = 15 x 86400 = 1,296,000
Hence, It is found that Fifteen days is equivalent to 1,296,000 seconds, Or we can say one million two hundred ninety-six thousand seconds.

How does the radius of a positive and negative ion compare to a neutral atom?
A neutral atom contains equal amount of proton and electron.
A negative ion contains extra electrons hence there is additional outer shell so it is expected that the radius is bigger than that of a neutral atom.
While a positive ion contains less electron so there is less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
positive ion, neutral atom, negative ion
suppose the correlation coefficient between the number of the college students in a city and the number of city buses is 0.89. which statement must be true?
Answer:
Step-by-step explanation:
Given that the correlation coefficient between the number of college students in a city and the number of city buses is 0.89.
We find that correlation coefficient is a measure of linear association between two variables.
When the absolute value of correlation coefficient is near 1, there is strong correlation. If correlation has a positive sign, there is a posiitive association between the two variables.
Here the correlation coefficient is positive and also near 1. Thus there is a strong linear correlation between the two variables.
Or whenever there is an increase in one variable there will be an increase in other variable also.

If (1, 2) and (3, 4) lie on the same line, give the slope-intercept equation of the line.
Final answer:
The slope-intercept equation of the line that passes through (1, 2) and (3, 4) is y = x + 1, with a slope of 1 and a y-intercept of 1.
Explanation:
To find the slope-intercept equation of a line that passes through the points (1, 2) and (3, 4), we first need to determine the slope of the line. We use the formula for the slope (m) given by the change in y over the change in x, or Δy/Δx. Calculating the slope, we get:
m = (4 - 2) / (3 - 1) = 2 / 2 = 1.
Now we have the slope, we can use the slope-intercept form of the line, which is y = mx + b, where m is the slope and b is the y-intercept. Plugging in one of the points, say (1, 2), into this equation gives us:
2 = (1)(1) + b
Which simplifies to:
b = 2 - 1 = 1
So the y-intercept (b) is 1. Therefore, the slope-intercept equation of the line is:
y = x + 1

Write the equation of the function whose graph is shown.
Answer:
[tex]y=1(x-5)^2 + 3[/tex]
Step-by-step explanation:
Given : from the graph vertex is (5,3)
Also graph passes through point (8,12)
We use vertex form of quadratic equation
General vertex form is
[tex]y=a(x-h)^2 + k[/tex]
vertex is (5,3)
h= 5 and k =3
So equation becomes [tex]y=a(x-5)^2 + 3[/tex]
Now we need to find out 'a'
We use (8,12) to find out 'a'
Plug in x=8 and y = 12
[tex]12=a(8-5)^2 + 3[/tex]
[tex]12=a(3)^2 + 3[/tex]
12= 9a + 3
subtract 3 on both sides
9 = 9a
divide both sides by 9
so a=1
Final equation is
[tex]y=1(x-5)^2 + 3[/tex]
An equation of the function of this graph is equal to [tex]y=1(x-5)^2 + 3[/tex]
Given the following data:
Points on the x and y-axis = (8, 12).Vertex (h, k)= (5, 3).How to write a function.The vertex form of a quadratic equation can be used to write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:

Determine whether 2y=3x-1 represents a direct variation. if it does, find the constant of variation.
The equation 2y=3x-1 does not represent a direct variation in its strict definition, as it includes a y-intercept. If the y-intercept is ignored, the constant of variation would be k = 3/2.
The equation 2y=3x-1 represents a direct variation if it can be written in the form y = kx, where k is the constant of variation. To determine if this equation represents a direct variation, we can solve it for y:
Divide both sides of the equation by 2 to isolate y:
y = (3/2)x - 1/2.
Since we can express y as an equation of the form y = kx + b, with b being a constant, it does not represent a pure direct variation, as direct variation should have a form y = kx without the constant term.
However, if the question is interpreted to include such linear relationships as direct variations despite the y-intercept, then the constant of variation would be k = 3/2.
