Define comparing.Mathematical number comparison is the process or method of comparing two numbers to determine whether one is less, bigger, or equal to the other. The comparison symbols for numbers are "=", which stands for "equal to," "=", which stands for "greater than," and " ", which stands for "less than." Comparing amounts is a technique for figuring out how much to compare units in relation to a different standard or reference unit. A common reference point is necessary for two comparing units to be compared; otherwise, they cannot be compared.

what is the sum of 21 and 5 times a number f is 61
Answer:
f = 8
Step-by-step explanation:
21 + 5f = 61
5f = 61 - 21
f = (61 - 21) / 5
f = 8
Answer:
f = 8
Step-by-step explanation:
"Sum" = addition
"Times" = multiplication
Write an equation to represent this scenario
21 + 5 * f = 61
Multiply 5 by f
21 + 5f = 61
Subtract 21 from both sides of the equation
5f = 40
Divide both sides of the equation by 5
f = 8

4. What are the coordinates of A after the reflection? (2 points)
5. Is the final figure congruent to the original figure? How do you know? (2 points)
The image of the original figure after the translation and reflection is congruent to the original figure.
Translation over a point is what?A particular type of transformation on the coordinate plane called translation keeps the size of the point or geometrical shape constant while only changing the position. Along the x-axis and y-axis in the coordinate system, the point or the figure can be moved in any direction, including up, down, right, left, and multiple directions.
1. By taking away 4 from the x-coordinate and adding 8 to the y-coordinate, we can translate a point 4 units left and 8 units up.
2. Point A after translation is situated at (-2, 9).
3. We negate the x-coordinate and leave the y-coordinate unaltered to indicate a point over the y-axis.
4. Point B is obtained by reflecting point A over the y-axis (2, 9).
5. Indeed, the resulting representation is consistent with the original figure since the rigid transformations of translation and reflection maintain angles and distances. As a result, the original figure's picture after translation and reflection corresponds to the original figure.

QuestionOn New Year's Eve the famous ball drops in Times Square. The crystal ball is 3.66 meters in diameter and weighs nearly 6tons. What volume can a sphere of this size hold? Report your answer in L but do not include the unit L in your answerbox. Round your answer to the nearest whole L. When entering your final answer do not include any commas. Theformula for the volume of a sphere is V =jar?
In order to calculate the volume of a sphere, we can use the formula:
\(V=\frac{4}{3}\pi r^3\)If the diameter is 3.66 meters, the radius is 1.83 meters, so we have:
\(\begin{gathered} V=\frac{4}{3}\cdot3.1416\cdot1.83^3 \\ V=25.67\text{ m}^3 \end{gathered}\)In order to convert from cubic meters to liters, we can use the relation:
1 m³ = 1000 L
So:
\(V=25.67\cdot1000=25670\text{ L}\)Therefore the volume of the sphere is 25670 L.
Distributive property simplify 5(3v-7)
Answer:
\(15v-35\)
Step-by-step explanation:
The distributive property states that \(a(b+c)=a*b+a*c\), where \(a\), \(b\), and \(c\) are real numbers. In this case, \(a=5\), \(b=3v\), and \(c=-7\). Therefore, \(5(3v-7)=5*3v+5*(-7)=15v-35\). Hope this helps!
Answer:
15v - 35
Step-by-step explanation:
start by distributing 5 to 3v.
5(3v - 7) aka 5 · 3v ⇒ 15v
distribute 5 to -7.
5(3v - 7) aka 5 · -7 ⇒ -35
you are left with 15v and -35, therefore your simplified expression is 15v - 35.

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation. What are the values a, b, and c in the following quadratic equation? -3x^2 -5x +9 =0
Answer:
The quadratic equation is in the standard form: ax^2 + bx + c = 0. To use the quadratic formula to find the solutions, we need to identify the values of a, b, and c in the equation:
a is the coefficient of the x^2 term, which is -3 in this case.
b is the coefficient of the x term, which is -5 in this case.
c is the constant term, which is 9 in this case.
Therefore, the values of a, b, and c in the quadratic equation -3x^2 - 5x + 9 = 0 are:
a = -3
b = -5
c = 9
Solve for θ if −10sinθ−8=5√3−8 and 0≤θ<2π.
The value of variable θ would be,
⇒ θ = 5π/3 and θ = 4π/3
We have to given that;
Expression is,
⇒ - 10sin θ - 8 = 5√3 - 8
Now, We can simplify as;
⇒ - 10sin θ - 8 = 5√3 - 8
⇒ - 10sin θ = 5√3
⇒ sin θ = - 5√3/10
⇒ sin θ = - √3/2
We know that sinθ = -√3/2 when θ = 4π/3 and θ = 5π/3 (among other angles).
However, since 0 ≤ θ < 2π, only the angles in the second and third quadrants are valid solutions for sinθ = -√3/2.
Therefore, the solutions are θ = 5π/3 and θ = 4π/3, option D is correct.

The first term, a₁ = 3
The last term an = 123
Common difference, d = 3 (because the sequence are multiples of 3)
Number of terms, n= ?
Find the number of terms, n:

Translation, rotation, and reflection are known as "rigid transformations". Effectively, you can cut the figure from some rigid material, and move it according to any of these transformations without causing it to deform in any way.
All lengths and angles retain their measures when the figure is rotated about any point, through any angle. The rotated figure is congruent with the original.

Use the power-reducing formulas to rewrite the expression in terms of first powers of the cosines of multiple angles.
5 cos4(x)
Using the power reducing formulas the expression \(5cos^4(x) = 5(1 + cos(2x))^{2/4}\).
What are power-reducing formula?We can define higher powers of a trigonometric function in terms of lower powers of the same function using the power-reducing formulas, which are trigonometric identities. Higher powers of cosine can be expressed using this formula in terms of sine and cosine's initial powers. For the other trigonometric functions, such as sine and tangent, there are equivalent formulas. These formulas can be used to solve trigonometric equations and to simplify trigonometric expressions.
The given function is 5cos^4(x).
Now, the power reducing formulas are given by:
\(cos(2x) = cos^2(x) - sin^2(x) = 2cos^2(x) - 1\\cos^2(x) = (1 + cos(2x))/2\)
Substituting the value of second equation in 1 we have:
cos(2x) = 2(1 + cos(2x))/4 - 1
\(cos(2x) = (2cos^2(x) - 1) = cos^2(x) - sin^2(x)\)
Now we have:
\(cos^2(x) = (1 + cos(2x))/2\)
Thus,
\(cos^4(x) = (1 + cos(2x))/2)^2\)
Now multiplying by 5:
\(5cos^4(x) = 5(1 + cos(2x))^{2/4}\)

Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. Are these samples representative of the school population? Explain.
No, the samples are not large enough to be representative.
Yes, both samples are random, so they are representative.
No, the samples might include some of the same people, so they are not representative.
Yes, the samples do not include the same people, so they are representative.
Answer:
D but see below.
Step-by-step explanation:
This question is badly thought out. 15 might be enough to be representative if the school only contains about 100 people.If B is true then it would be the answer.If D was true, it would be the answer. If C was true, it could be the same answer.So you have a question that has no clear answer. If Jeff took grade 11 and Lana took grade 12, that would make the answer much clearer. At least there would be no duplicates.
If you could refine the question a little more, you might get a clearer answer. I don't think this question should be asked and I sure don't think you should try and give an answer.
However that's not how schools work. So I would pick D, but by some bizarre method, the asker (like edge) might think of a way to make A B or C true.

Assume that a piece of land is currently valued at $50,000. If this piece of land is expected to appreciate at an annual rate of 5% per year for the next 20 years, how much will the land be worth 20 years from now?
The value of the land 20 years after it appreciates at annual rate at 5% is $132676.47.
What is appreciation of assets?An asset's value increases over time through a process called appreciation. Depreciation, on the other hand, reduces an asset's value throughout its useful life. The rate at which an asset's value increases is known as the appreciation rate. An increase in the value of financial assets, such as stocks, is referred to as capital appreciation. When a currency appreciates, it means that its value increases when compared to other currencies on the foreign exchange markets.
The annual rate is given as 5%.
The new value after 20 years can be calculated using the formula:
\(A = P * (1 + r/n)^{(nt)}\)
Substituting the values we have:
\(A = $50,000 * (1 + 0.05/1)^{(1*20)}\\A = $50,000 * 1.05^{20}\\A = $132,676.47\)
Hence, the value of the land 20 years after it appreciates at annual rate at 5% is $132676.47.
