The Good Ole Times magazine charges for ads by the "column inch." A column inch is as wide as one column, and it is one inch high. The cost is $67 per column inch. How much would the magazine charge to print a 2 ½-inch ad?
Cost of the ad is $167.5
What is cost?
A cost is the worth of money that has been used up to create something or supply a service and is thus no longer accessible for use in production, research, retail, or accounting. In business, the cost might be one of acquisition, in which case the money spent to obtain it is recognized as cost. In this situation, money is the input that is used to purchase the item. This acquisition cost might be the total of the original producer's production expenses and the acquirer's additional transaction costs over and above the amount paid to the producer. Typically, the price includes a profit margin above the cost of manufacture.
The cost of the ad per column inch = $67
So, the cost of 2¹/₂ inch = 67 x 2¹/₂ = $167.5

○ line l is parallel to line m; converse of corresponding angles postulate
○ line p is parallel to line q; converse of same side interior angles theorem
Answer:
line I is parallel toM to know how you got follow me and ask the the question
Explanation:
Erase line L since we won't be using it. Erase every angle but angle 5 and angle 6.
If angle 5 and angle 6 are congruent, then we can use the converse of the corresponding angles postulate to show that lines p and q are parallel.
Angle 5 and angle 6 are corresponding angles since they are both in the same northeast corner, i.e. they're both in the same corresponding position so to speak.
Teresa, Pablo, and Deon served a total of 55 orders Monday at the school cafeteria. Teresa served 9 fewer orders than Deon. Pablo served 2 times as many orders as Deon. How many orders did they each serve?
Deon served 16 orders. Pablo served 32 orders. Teresa served 7 orders.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let Deon order be x , since Teresa served 9 fewer orders than Deon. , then Teresa order is x - 9,
since Pablo served 2 times as many orders as Deon, it means Pablo's order is 2x . combining all
Deon 's orders = x
Pablo's order = 2x
Teresa 's order = x - 9
Total order = 55
Then
x + 2x + x - 9 = 55
4x - 9 = 55
4x = 55 + 9
4x = 64
x = 16
Therefore :
Deon served 16 orders
Pablo served orders = 32 orders
Teresa served 16 - 9 orders = 7 orders

As a result, the value of x is 20. Vertically opposite angles are formed by two straight intersecting lines that are opposite one another at a specific vertex.
What is vertical opposite angle?Vertically opposite angles are formed by two straight intersecting lines that are opposite one another at a specific vertex. Angles that are vertically opposite each other are equal. These are sometimes referred to as vertical angles.Here to find y,
∠A = ∠B ( vertically opposite angles are equal ).
5y - 8 = 42
5y = 42 +8
5y = 50
y = 10
To find ∠A,
∠ A = 5y - 8
= 5 x 10 - 8
= 50 -8
= 42°.
we know that angle on a straight line is 180°.
So , ∠A + ∠C = 180°
42 + ∠C = 180°
∠C = 180 - 42
∠ C = 138°.
Since ∠C = ∠D (vertically opposite angle ).
∠D = 138°
As a result, the value of x is 20.

Angle C is an acute angle with sec C = 9/4 and sin C =
√65/9. What are the values of cos C and csc C?
From trigonometric ratios we calculate the value of the cos C is 4/9 and the value of cosec C is 9/√65 .
Real functions known as trigonometric functions in mathematics connect right-angled triangle angles and the ratios of their two side lengths.
The terms trigonometric functions, circular functions, and angle functions are also used to describe them. Trigonometric functions are frequently employed in all fields of study involving geometry, including geodesy, solid mechanics, celestial mechanics, and many more. Given that one of the most fundamental periodic functions is the Fourier transform, it is frequently employed to examine periodic phenomena.Sine, cosine, and tangent are the three trigonometric functions that are employed in modern mathematics the most frequently. The less common cotangent, secant, and cosecant are their reciprocals. The hyperbolic functions and their corresponding inverse functions have analogues for each of these six trigonometric functions.We know that sec C = 1/cos C
Hence the value of cos C = 4/9 .
Again we know that the value of sin C=1/cosec c
Therefore the value of cosec C is 9/√65 .

A line passes through the points (7, 10) and (7, 20). What is true about the slope of the line? *
The slope of the line is indefinite (∞). Also, the line will be parallel to the x-axis.
It is given in the question that a line passes through the points (7, 10) and (7, 20).
We have to find the slope of the line.
We know that,
Slope of a line with coordinates (a,b) and (c,d) is given by:-
(d - b)/( c - a)
Here,
a = 7,
b = 10,
c = 7 and,
d = 20
Hence, we can write,
Slope of the line = (20 - 10)/( 7 - 7) = 10/0 = ∞.
Hence, the slope of the line is indefinite.
Here, as the x -coordinate of both the points are same, this line will be parallel to the x - axis.

what is the answer to -3(x+4)=-6x+18
Answer:x=10
Step-by-step explanation:
1. Simplify both sides of the equation. -3(x+4)=-6x+18 to -3x - 12=-6x + 18
2. Add 6x to both sides. -3x - 12=-6x + 18 to -3x - 12 + 6x=-6x + 18 +6x which would equal to 3x - 12=18
3. Add 12 to both sides. 3x - 12 + 12=18 + 12.
4. Divide both sides by 3. 3x/3=30/3 which equals x=10.

Triangles 2, 4, 6, 8, 9, 10, 12, 14, and 15 are not translations of triangle 1.
What is translation?In mathematics, a translation is an up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more directions have been altered. There is no change in the shape because it is simply being moved from one location to another.
The object may move left at first, then right, and so forth. The object's position can change, as well as the manner in which it does so. Each point on the shape will move by the same number of units during translation.
Therefore, triangles 2, 4, 6, 8, 9, 10, 12, 14, and 15 are not translations of triangle 1.

In a class of 42 students, 25 take biology,15 take history,and 18 take biology but not history.i.Draw a Venn diagram to show the informationii.find how many students take niether history nor biology
In the class, there is a total of 42 students.
25 take biology.
15 take history.
18 take biology but not history.
There are four situations that you have to include in the Venn diagram:
"The students take only biology"
"The students take only history"
"The students take biology and history"
"The students take neither classes"
To draw the Venn diagram, you have to make one circle for each subject, i.e. one circle for biology and one for history, and label them.
Then you have to enter the similarities between both subjects, this means, where the circles overlap, you will find the students that take both subjects.
Finally, outside the circles, you will find the students that take neither subject:
Now, you have to determine how many students are included in each part of the Venn Diagram.
1) You know that 25 students take biology and that 18 take biology but not history, to determine the number of students that take both subjects, you have to calculate the difference between both values:
[tex]25-18=7[/tex]7 students take biology and history.
2) 15 students take history out of these you know that 7 take also biology. To determine the number of students that take only history, you have to calculate the difference between both values:
[tex]15-7=8[/tex]8 students take history but not biology.
3) To determine the number of students that take neither class, you have to subtract to the total number of students, those who take only biology plus those who take only history plus those who take both classes:
[tex]\begin{gathered} \text{Neither}=\text{Total-(only biology + only history + both)} \\ \text{Neither}=42-(18+7+8) \\ \text{Neither}=42-33 \\ \text{Neither}=9 \end{gathered}[/tex]9 Students of the class take neither class.
Finally, you can write each value in the corresponding part of the Venn diagram:
• Inside the green circle, you have to include the 18 students that take only biology.
,• Inside the blue circle, you have to include the 8 students that take only history.
,• Where both circles overlap, you have to include the 7 students that take both classes.
,• Outside the circles, you have to include the students that take neither.

why do you think its difficult For students to understand that the product of two negative integers is positive, and what (if anything) can be done to help Student's understand this idea?
The product of any two negative numbers is positive.
Consider a positive number to be something as a gift, and a negative number to be something you give to me.
So, let's say you get 4 laptops from me, and - 4 means you give away 4 laptops to me.
Now when you say - 4 + - 4 + - 4 + - 4 + - 4.
This means that you are giving away 4 laptops 5 times to me, so basically you have given away 20 laptops, which means I have 20 laptops and you have - 20.
Now, - 4 * - 5 means, you give away 5 laptops, for - 5 times to me. But the second number is - 4, so the receiver, that is me, is giving it back to you. Thus indirectly, you gave away 4 chocolates to yourself 5 times. Thus you have 20 laptops.

Answer: Zero Product Property
Step-by-step explanation:
Answer:
Well, am not sure if am correct, if a = 0 and if b = 0, then both terms have the same value. The law this equation ab = 0 is following is called Zero Product Property.
Step-by-step explanation:
a x b
Suppose a x b = 0
Then either a = 0 or b = 0
so these are the two possible cases.
1. 0 x b = 0
2. a x 0 = 0
Therefore, the product of the a and b is equal to zero when a is equal to zero or b is equal to zero. This rule is the zero product property.
