The inequality representing d, the total number of days is 76.5d + 24 ≤ 330
How to determine the inequality that represents the scenario?From the question, the given parameters are:
Charges per day = $76.50
Charges per mile = $0.06
This means that the equation that represents the total charges for d days is
Total = Charges per day x Number of days + Charges per mile x Number of miles
So, we have
Total = 76.5 x d + 0.06 x m
Where m represents the number of miles
From the question, we have
He plans to drive 400 miles.He has at most $330 to spend.This means that
m = 400 and Total ≤ 330
So, we have
76.5 x d + 0.06 x 400 ≤ 330
Solve
76.5 x d + 24 ≤ 330
This gives
76.5d + 24 ≤ 330
Hence, the inequality that represents the scenario is 76.5d + 24 ≤ 330

Find the area of the entire region round two decimal places
SOLUTION.
The area of the entire region will be to find the area of the isosceles triangle and the semi-circle.
[tex]\begin{gathered} \text{Area of the triangle is } \\ =\frac{1}{2}\times a\times b\times\sin \theta \\ \text{Where } \\ \text{where a and b are two sides and }\theta=angle\text{ betwe}en\text{ the two sides } \end{gathered}[/tex]Then
[tex]\begin{gathered} =\frac{1}{2}\times8\times8\times\sin 72.6 \\ =32\sin 72.6 \\ =30.54\text{unit}^2 \end{gathered}[/tex]The area of the isosceles triangle is 30.354 square units
We need to obtain the diameter of the semi-circle using the cosine rule
We need to obtain the value of x,
[tex]\begin{gathered} x^2=8^2+8^2-2(8)(8)\cos 72,6 \\ x^2=128-128\cos 72.6 \\ x^2=128-38.27 \\ x^2=89.72 \end{gathered}[/tex]Take square root of both sides, we have
[tex]x=\sqrt[]{89.72}=9.74[/tex]Hence, the diameter is 9.74
Then the radius will be
[tex]r=\frac{9.74}{2}=4.87[/tex]The area of the semi-circle is
[tex]\begin{gathered} =\frac{1}{2}\pi r^2 \\ =\frac{1}{2}\times3.14\times4.87^2 \\ =37.24\text{unit}^2 \end{gathered}[/tex]The area of the semi circle is 37.42 square units
Therefore the area of the region will be
[tex]\begin{gathered} =\text{Area ot triangle + Area of semi circle } \\ =30.54+37.42 \\ =67.96uniits^2 \end{gathered}[/tex]Thus
The area of the region is 67.96 units²

The multiplication expression is L×w
The expression is written as N= r+ g + w + b
The final product = 200 boxes
How to determine the expressionIt is important to note that the formula for calculating the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleThe area can be determined by multiplying the length and the width and also by then adding the boxes.
Mathematically, we have;
10( 4 + 5 + 4 + 7)
Also
L × w = r + g + w + b
Hence, we have that L×w is a multiplication expression.
Total number of boxes for the length = 20
Total number of boxes for the width = 10
Total area = L×w = 20×10=200
Number of red boxes = 46Number of green boxes = 46Number of blue boxes = 46Number of white boxes = 62We then have;
N= r+ g + w + b
but r = g = b
Also,
L×B = 3r + w

Alberto's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 6 adult tickets and 14 student tickets for a total of $84. The school took in $105 on the second day by selling 12 adult tickets and 7 student tickets. What is the price each of one adult ticket and one student ticket?
Answer:
Adult: $7
Student $3
Step-by-step explanation:
Hello!
We can use a system of linear equations to find the solution.
Let the price of adult tickets be x, and the price of student tickets are y.
The price of Day 1 can be represented by 6x + 14y = 84, and the second day can be represented by 12x + 7y = 105.
We can solve the system by graphing both equations on a coordinate plane and finding the point of intersection.
The point of intersection happens at x-coordinate 7 and y-coordinate 3. Recall that x is assigned to the price of adult tickets, and y is assigned to student tickets.
The price of adult tickets is $7, and the price of student tickets is $3.
graph of this equation x=3/5y

The part labelled C is 13 ones
How to determine parts A, B, and C using rectangular model developed by Carterinformation given in the question
A rectangle is divided into two sections by a vertical line
The left section is labeled inside with 260
The left edge of the rectangle is labeled 13
other information is in the attached diagram
How to used the model
Carter's model is a rectangle of length 273 and breadth 13.
273 / 13 = 21
This means that dividing the length into 13 places each unit is 13
273 - 13 = 260
hence the 260 represents 20 units, since one unit is subtracted
The knowledge of place value help to get the numbers to be arranged in tens and ones
putting the numbers in tens is done by dividing by 10
= 260 / 10
= 26
hence, A in tens is equivalent to 26
putting the numbers in ones is dine by dividing by 1
C = 13 / 1
C = 13 ones
a unit is 13, B = 13
B covers same space as C so they are equal

Approximate the correlation of the data shown below?
The approximate correlation of the data shown on the diagram above is: C. -0.5.
The question says we should approximate the correlation using the given scatter plot. Below shows a detailed explanation on how to do a rough estimation of the possible value of the correlation.
What is the Approximate Correlation of a Data?
Correlation Coefficient, r, is a numerical value of -1 to 1, which tells how strongly related two variables are. If the points on a scatter plot form a trendline that slopes upwards, it is a positive correlation. If it slopes downwards, it is a negative correlation.
The magnitude of the correlation coefficient is dependent on how father apart the points are from each other along a trend line. If they are much farther apart from each other, the correlation coefficient would far from 1 and -1, and close to zero. If they are closer, it would be close to 1 or -1, and far from 0.
The scatter plot shows the data points are moderately spaced from each other and the trendline slopes downwards. Therefore, the best estimate for the correlation is: C. -0.5.

Answer:

Explanation:
The slope-intercept form of the equation of a line has the form:
y = mx + b
Where m is the slope and b is the y-intercept.
The slope can be calculated as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are the coordinates of two points in the line.
So, replacing (x1, y1) by (1, -1) and (x2, y2) by (2, -1), we get:
[tex]m=\frac{-1-(-1)}{2-1}=\frac{-1+1}{1}=\frac{0}{1}=0[/tex]On the other hand, the y-intercept is the point where the line crosses the y-axis. So, the y-intercept is -1.

In accordance with the system of linear equations, the ordered pair is (x, y) = (1, 2).
How to find the values associated to an ordered pair
Ordered pairs are constructions characterized by two components, typically real numbers. The most common form of notation is (x, y). In this problem we need to resolve a system of linear equations to obtain the needed values. We find a system of two equations and two variables:
x + y = (3 - x) + (3 - y)
x - y = (x - 2) + (y - 2)
First, simplify each expression of the system:
First equation:
x + y = 6 - x - y
2 · x + 2 · y = 6
x + y = 3
Second equation:
x - y = (x - 2) + (y - 2)
x - y = x + y - 4
- 2 · y = - 4
y = 2
Second, substitute in the first equation:
x + 2 = 3
x = 1

minutes to drive to the car wash. How many minutes does it take Allie to drive to the store and then to the car wash?
It takes 1190 minutes for Allie to drive to the store and then to the car wash.
According to the question,
We have the following information:
Time taken by Allie to drive to the store = 456 minutes
Time taken by Allie to drive to the car wash from the store = 734 minutes
Now, we have to find the total time in minutes. So, we will add the total time taken by Allie to drive to the store and then to the car wash.
(Note that the time asked in the question is in minutes. So, we do not need to change the units of given time.)
Now,
The total time taken by Allie to drive to the store and then to the car wash = Time taken by Allie to drive to the store + Time taken by Allie to drive to the car wash from the store
The total time taken by Allie to drive to the store and then to the car wash = (456 + 734) minutes
The total time taken by Allie to drive to the store and then to the car wash = 1190 minutes
Hence, the total time taken by Allie to drive to the store and then to the car wash is 1190 minutes.
