PAGEANT is most similar in meaning to beauty, sovereign, gallant, show?

Answers

Final answer:

The term 'pageant' is most similar in meaning to 'show.' Both terms refer to public exhibits or performances intended to entertain.

Explanation:

The word pageant is conceptually closest in meaning to the term 'show.' A pageant typically refers to a public entertainment consisting of a procession of people in elaborate, colorful costumes, or an outdoor performance of a historical scene. This coincides with the term 'show,' which generally signifies a public display or exhibition, especially when intended to entertain. Drawing from the research conducted by anthropologist Marcia Ochoa, we commonly see pageants in the context of beauty competitions, such as Miss Venezuela, or similar contests held by specific communities, such as transformistas in Venezuela. These events focus on the public presentation of candidates, much like a show.

The word “pageant” is most similar in meaning to “show”.

The word “pageant” is derived from the Latin word "pagina," which means a play or stage. In modern usage, a pageant is a public entertainment consisting of a procession of people in elaborate, colorful costumes, or an outdoor performance of a historical scene. It’s essentially a type of show that is often grand and celebrates a special event or anniversary.

Beauty: This term often refers to a combination of qualities, such as shape, color, or form, that pleases the aesthetic senses, especially the sight. In the context of a beauty pageant, it’s a show that judges its contestants primarily on their physical appearance. However, the term “beauty” itself doesn’t convey the aspect of a show or performance that “pageant” does.

Sovereign: This term refers to a supreme ruler, especially a monarch. A sovereign might be a figure in a pageant, but the word “sovereign” itself refers to a position of power and rule, not a show or performance.

Gallant: This term is used to describe someone brave, heroic, or chivalrous. A person might behave gallantly in a pageant, but again, the word “gallant” itself doesn’t convey the meaning of a show or performance.

So, among the options provided, “pageant” is most similar in meaning to “show”, as both involve a public display or performance.

There's 6 times as many dogs as cats.If the total number of dogs and cats is 35, how many dogs are there?

Answers

Let cats = X

Then doges = 6x ( 6 times as many cats, so multiply 6 by number of cats)


Now you have X + 6X = 35  ( number of cats plus number of doags equal 35)

X +6x = 35

Simplify:

7X = 35

Divide both sides by 7 to solve for x:

X = 35 / 7

X = 5

Cats = X, so there are 5 cats.

Dogs = 6X = 6(5) = 30 total dogs.


Kris wanted to understand whether students at her school were in favor of an extended school day. She surveyed some students and displayed the results in the table below: In favor Opposed Undecided Grade 9 6 4 8 Grade 10 10 11 9 Grade 11 12 15 11 Grade 12 15 6 14 If the principal randomly selects a student in grade 10 from this survey, what is the probability that the student is opposed to extending the school day?

Answers

the table below:

Grade        In favor   Opposed Undecided    Total

Grade 9     6                   4                       8                18

Grade 10     10         11                        9                30

Grade 11     12        15                      11                  38

Grade 12     15        6                      14                  35

If the principal randomly selects a student in grade 10 from this survey,

the probability that the student is opposed to extending the school day

P ( student in grade 10 is opposed)= Number of student in opposed(grade10) / total number of students in grade 10

Number of student opposed who is in grade10 = 11

total number of students in grade 10 = 30

P( student in grade 10 is opposed)=  [tex]\frac{11}{30}[/tex]

= 0.37

the probability that the student is opposed to extending the school day= 0.37

Final answer:

The probability that a randomly selected grade 10 student from the survey is opposed to extending the school day is 11/30, or approximately 36.67%.

Explanation:

The student's question pertains to the probability of selecting a grade 10 student who is opposed to extending the school day based on the survey results provided.

To calculate this probability, we consider only the grade 10 students. According to the table, there are 10 students in favor, 11 opposed, and 9 undecided within grade 10, making a total of 10 + 11 + 9 = 30 students surveyed in the tenth grade.

The probability that a randomly selected grade 10 student is opposed to an extended school day is the number of grade 10 students opposed divided by the total number of grade 10 students surveyed.

Mathematically, it can be represented as P(Opposed) = Number of opposed students in Grade 10 / Total number of students in Grade 10 surveyed. By plugging in the numbers:

P(Opposed) = 11 / 30

Therefore, the probability is 11/30 or approximately 0.3667, which can be expressed as a percentage by multiplying by 100, yielding about 36.67%.

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than he read on day one. On the third day, he read ix pages less than what he read on the first day. If he has read the entire book that contains 458 pages, how many pages did he read on day three?

Answers

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: [tex]x+2x+x-6=458[/tex]

[tex]4x-6=458[/tex]

[tex]4x=464[/tex]

[tex]x=116[/tex]

So on the third day, Aiden read [tex]x-6=116-6=110[/tex] pages.

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given condition, for the missing value, we can use variables.

Since all the number of pages can be found if we'd have known the number of pages he read on the first day,  thus,

Let we take the number of pages Aiden read on the first day = P

Then, by the given condition, we get:

Number of pages Aiden read = twice the number of pages than he read on day one = [tex]2 \times P[/tex]

On third day = six pages less than what he read on first day = [tex]P - 6[/tex]

Since in these three days, he completed the whole book of 458 pages, thus, all these counts of pages he read in three days should total to 458. Or,

[tex]P + 2 \times P + P - 6 = 458\\4 \times P - 6 = 458\\\\\text{Adding 6 on both the sides and dividing by 4}\\\\\dfrac{4 \times P}{4} = \dfrac{458+6}{4}\\\\P = 116[/tex]

Thus, on the first day, Aiden read 116 pages.

Since on the third day, he read 6 pages less than the amount of pages he read on the first day, thus, number of pages he read on third day = 116 - 6 = 110

Thus, The number of pages Aiden read totals to the total number of pages of books. On the third day, Aiden read total 110 pages.

the expression 9/2÷3 is the same as

Answers

Answer:

4.5 ÷ 3

Step-by-step explanation:

9/3 = 4.5

therefore this is the same as the previous expression

Final answer:

The expression 9/2 / 3 is equivalent to 9/2 * 1/3, which simplifies to 9/6 or 1.5. This multiplication by the reciprocal ensures the equality of the operation.

Explanation:

The expression 9/2 / 3 can be understood in terms of multiplication and division. When we divide by a number, it is the same as multiplying by its reciprocal. In this case, dividing by 3 is the same as multiplying by 1/3. Hence, we can rewrite the expression as 9/2 * 1/3.

To calculate this, we multiply the numerators together and the denominators together:

(9*1) / (2*3) = 9 / 6 = 1.5, or 3/2 when written as a fraction.

Performing the same operation on both sides of the equals sign maintains the equality. So, if any fraction has the same number in the numerator and the denominator, that fraction is equal to 1.

Final answer:

The result of dividing the polynomial 2x³ + 6x² + 6x + 2 by x + 1 is 2x² + 4x + 2, which can be obtained using synthetic division.

Explanation:

The given question is about polynomial division. To divide a polynomial, we commonly use long division or synthetic division. In this case, we are dividing the polynomial 2x³ + 6x² + 6x + 2 by (x + 1).

Using synthetic division, we get:

First, write down the coefficients of the dividend polynomial (2, 6, 6, 2) and below them the divider (in this case, -1, because we have 'x + 1' and '-1' is the root of 'x + 1'). Copy down the leading coefficient (2 in this case) to the bottom line. Multiply it by the root identified earlier, and add it to the next coefficient (2*-1 = -2; 6 + -2 = 4). Repeat this process (4*-1 = -4; 6 + -4 = 2). At the end, you should see that the remainder is zero (2*-1 = -2; 2 + -2 = 0).

Therefore, the quotient is 2x² + 4x + 2.

Answers

Answer: Yes

Sales Tax = 7% of the 18$, which means we should multiply 18 by 0.07:

18 × 0.07 = 1.26

Sales tax = 1.26$

Now we have to add the sales tax to the original cost of the DVD which is 18$:

18 + 1.26 = 19.26

So the total cost is 19.26$

Since she has 20$, she then has enough money.

How do you write out the domain and range of a function?

Answers

x + 5 = 53 = \left[x \right] = \left[ 48\right][x]=[48]
you write out the domain and range of a function

The domain and range of a function are sets of numbers that represent all possible inputs and outputs, respectively. They can be written using interval or set-builder notation, considering the function's definition and any restrictions. For instance, the domain [0, 20] implies the function is defined for any number between 0 and 20, inclusive.

Writing Out the Domain and Range of a Function

To write out the domain and range of a function, you first need to determine which values can be inputs (domain) and which can be outputs (range). The domain and range are written as sets of numbers, often in interval notation or set-builder notation. For instance, if a function f(x) is defined for all x such that 0 <= x <= 20, then its domain could be written as [0, 20].

The range is determined by evaluating the function at every value in its domain to find all possible outputs. For example, if f(x) = x^2 and x <= 0, the range would include all y <= 0 because squaring a non-positive number always yields a non-negative result. To restrict a function's domain and make it invertible, like the function y = x^2 restricted to x <= 0, one must consider which portions of the function pass the horizontal-line test.

For a function f(x) that is a simple relation, say f(x) = 2 for all x in its domain, the range is just {2} because no matter what x-value you put in, the output is always 2. In more complex functions, the graph may need to be analyzed to determine the exact range. When expressing domain and range, the domain is all valid inputs while the range is all possible outputs of the function.
