Marked price 39 selling price 31 what is the discount offered
Marked price: 39 dollars
Selling price: 31 dollars
Discount: ???
First stepSubtract the post-discount price from the pre-discount price.
31-39=-8
Second stepDivide this new number by the pre-discount price.
-8/39=-0.20512820512
Third step:Multiply the resultant number by 100.
-0.20512820512×100= -20.512820512
Fourth stepRound the number
-20.512820512 → -20.5
Answer:The discount was %20.5 off

A restaurant offers a catering service which costs $16.50 per person with a $74.75 service charge. For parties of 40 or more people, a group discount applies, and the cost is $11.75 per person along with the service charge dropping to $37.00. Write a piecewise-defined function which calculates the total cost, T, (in dollars) of the catering service, which serves n people.
Answer:
16.50+91.25=91.25
91.25×40=3650
11.75-37.00=-25.25
Total cost, T of the catering service, which serves n people = T = 16.50n + 74.75 and T = 11.75n + 37.00
Given,
Charges per person = 16.50
Service charges = 74.75
Let n be the number of the people,
Let T be the total cost
Now, according to the given question,
T = 16.50n + 74.75
If n>=40
T = 11.75n + 37.00
So, we have 2 equations which define the total cost -
T = 16.50n + 74.75,
T = 11.75n + 37.00

At a school, 60% of the sixth-grade students said that pizza is their favorite kind food. If 210 sixth-grade students prefer pizza, how many sixth-grade students are at the school?
Answer:
350
Step-by-step explanation:
Let \(s=\) total number of sixth-grade students.
It is given that 60% of sixth-grade students prefer pizza which is equivalent to 210 sixth-grade students. With this, the following can be written:
\(60\%s = 210\)
\(0.6s=210\) (\(60\%\) can be converted into the decimal form \(0.6\))
\(s = 210\div 0.6\)
\(=350\)
∴ There is a total of 350 sixth-grade students in the school.

About 42% of people who get their eyes examined are found to be nearsighted (unable to see objects at a distance). What is the probability of an ophthalmologist examining five people until he finds the first patient who is nearsighted?.
The probability that first patient is who is nearsighted is 0.027552
What is probability?
Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is stated. To forecast the likelihood of events, probability has been introduced in mathematics.
42% people are examined nearsighted
∴ 100- 42
= 58%
So 58% people are examined with no nearsighted
The likelihood that an ophthalmologist will first evaluate 5 people who are not nearsighted, then 1 person who is, is:
\(P = 0.58^{5}* 0.42^{1}\)
P = 0.0656 * 0.42
= 0.027552

Let N be a normal subgroup of a finite group G. Prove that the order of the group element gN in G/N divides the order of g.
The order of\($gN$\) divides \($k$\), as required.
Let \($g\in G$\) be an arbitrary element and let \($k$\) be the order of \($g$\), that is, \($g^k=e_G$\), the identity element of \($G$\). We want to show that the order of \($gN$\) in \($G/N$\) divides \($k$\).
Consider the coset \($g^iN\in G/N$\) for some positive integer \($i$\). We want to find the smallest positive integer \($j$\) such that \($(gN)^j = g^jN = g^iN$\). Since \($g^iN = g^k(g^i)^kN = g^kN$\), we have \($(gN)^j = g^{jk}N = g^iN$\), which implies \($g^{jk-i}\in N$\).
Since \($N$\) is a normal subgroup of\($G$\), we have \($g^{jk-i}\in N$\) if and only if \($g^{jk-i}g^j=g^{jk}\in N$\). This shows that \($g^{jk}$\) is in the kernel of the canonical homomorphism \($\pi:G\to G/N$\), so\($k$\) is a multiple of the order of\($gN$\) in \($G/N$\).
Therefore, the order of \($gN$\) divides \($k$\), as required.

The triangular-shaped has a perimeter of 990 feet. walking path in the park shown . Write an equation to find the length of the side of the path represented by x.
Answer: So the length of one side of the triangular-shaped walking path is 330 feet.
Step-by-step explanation:
The perimeter of the triangular-shaped walking path is 990 feet, and the length of one side is represented by x. We can write an equation to find x using the formula for the perimeter of a triangle:
P = a + b + c
Where P is the perimeter, and a, b, and c are the lengths of the sides of the triangle. Since one of the sides is represented by x, the equation can be written as:
990 = x + x + x
Simplifying the equation, we can find the value of x:
990 = 3x
Dividing both sides by 3, we get:
330 = x
So the length of one side of the triangular-shaped walking path is 330 feet.

15. a music concert is organized at a memorial auditorium. the first row of the auditorium has 16 seats, the second row has 24 seats, the third row has 32 seats, and so on, increasing by 8 seats each row for a total of 50 rows. find the number of people that can be accommodated in the sixteenth row
The equation for the nth term in the arithmetic sequence is 8n + 8.
The number of people that can be accommodated in the 16th row is 136.
What is an arithmetic progression?Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.
Given that,
No. of seats in first row = 16
No. of seats in second row = 24
No. of seats in third row = 32
Total number of rows = 50
It forms an arithmetic progression
First term = a = 16
common difference d = 8
Number of terms, n = 50
(A) The formula for the n th term of an arithmetic progression is given by
Tn = a + (n - 1) d
= 16 + (n-1) 8
= 16 + 8n - 8
Tn = 8n + 8
(B) Now,
n = 16
The number of seats in 16 th row is given by
T(16) = 8 x 16 + 8
T(16) = 136 seats
Hence, (A)The equation for the nth term in the arithmetic sequence is 8n + 8. and (B) The number of people that can be accommodated in the 16th row is 136.

Use the formula A = P (1 + r/n)nᵗ to solve the compound interest problem. Find how long it takes for $1700 to double if it is invested at 4% interest compounded monthly. The money will double in value in approximately __ years. (Do not round until the final answer. Then round to the nearest tenth as needed.)
To solve the compound interest problem, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A represents the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the time in years.
In this case, we want to find how long it takes for $1700 to double. The principal amount (P) is $1700, the interest rate (r) is 4% (or 0.04 as a decimal), and the interest is compounded monthly, so n = 12. We need to solve for t.
The formula becomes: 2P = P(1 + r/n)^(nt).
Dividing both sides of the equation by P, we get: 2 = (1 + 0.04/12)^(12t).
Taking the natural logarithm of both sides, we have: ln(2) = ln[(1 + 0.04/12)^(12t)].
Now, divide both sides by ln(1 + 0.04/12): t = ln(2) / [12 * ln(1 + 0.04/12)].
Using a calculator, we find that t is approximately 17.7 years.
Therefore, it takes approximately 17.7 years for $1700 to double if it is invested at 4% interest compounded monthly.

There is a line that includes the point (0, –9) and has a slope of -16/7 What is its equation in
slope-intercept form?
Answer:
y= -16/7x-9
Step-by-step explanation:
equation: y=mx+b where x and y are coordinates,m=slope and b=y intercept
slope= -16/7
coordinates=(0,-9)
input into the equation to get b(y-intercept):
-9=-16/7(0)+b
-9=0+b
b= -9
now input slope and y-intercept to get the equation:
y= -16/7+(-9)
y= -16/7x-9
Pls mark as brainliest :/
OR
Coordinate is (0,-9)
means at this point the line meets y-axis(i.e y-intercept) because x=0 so we get y intercept i.e -9
the gradient is given which is -16/7
just input into y=mx+b
y= -16/7x-9

provide the missing information. the function f : = {(1, 5), (-2, 3), (-4, 2), (2, 5)} (is/is not) a one-to-one function. please respond only with: is or is not answer:
The function f: {(1, 5), (-2, 3), (-4, 2), (2, 5)} is a one-to-one function. It satisfies condition where each input value maps to unique output value, ensuring no repetition or multiple inputs leading to the same output.
A one-to-one function, also known as an injective function, is a type of function where each input value is uniquely mapped to an output value. In the given function f: {(1, 5), (-2, 3), (-4, 2), (2, 5)}, we can observe that each input value corresponds to a distinct output value. For example, the input 1 is mapped to the output 5, and no other input has the same output. Similarly, the inputs -2, -4, and 2 are associated with the outputs 3, 2, and 5 respectively, without any repetition.
This lack of repetition or duplication in the outputs demonstrates that the function is one-to-one. Each input has a unique correspondence with its output, and no two different inputs yield the same output value. Therefore, based on the provided set of mappings, we can conclude that the function f is indeed a one-to-one function.
