Ver en españolWhat is the area?5 in5 in square inches
From the question, we are asked to find the area.
Since all the sides of the figure are the same, then it is a square.
So we will be using the area of a square formula to solve it.
Formula for area of a square is:
Area = a x a = a²
a = 5 in
So,
Area = 5 x 5 = 5² = 25
Therefore, the area of the square is 25 in²

Q3. If the sum of three consecutive odd number is 81, find the numbers.
Answer:
25, 27, 29Step-by-step explanation:
If the sum of three consecutive odd number is 81, find the numbers.
remove from 81 the difference between the numbers (2 + 2 + 2) divide by three and find the first, add 2 and find the second, to the result add 2 again and you have the third number(81 - 6) : 3 = 25
25 + 2 = 27
27 + 2 = 29

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.

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

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.

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.

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.

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.
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 .

What are Vertical Angles?When two lines that are straight intersect with each other, they form two pairs of opposite angles that are called vertical angles.
Vertical angles share a common vertex both no common sides and are therefore referred to as non-adjacent angles.
Thus, the image shows that lines intersect to form angle 4 and angle 7.
Angle 4 and angle 7 share a common vertex but do not share a common side, hence they are nonadjacent to each other, as shown in the diagram.
