Mitchell went on a shopping trip to Kensington. He purchased a pair of headphones originally
priced at $50 but discounted 60%. If sales tax in Kensington is 15%, what was the total cost?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The total cost of the pair of headphones is $23.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/200 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
105 = 10/100 = 1/10
We have,
Original price of the headphones = $50
60% of $50
= 60/100 x 50
= $30
The price of the headphones after the discount.
= $50 - $20
= $20
The amount of sales tax.
= 15% of $20
= 15/100 x 20
= $3
The total cost.
= $20 + $3
= $23
Thus,
The total cost of the pair of headphones is $23.

The equation is:
\(x^2-64=0\)
One solutions is 8.
To find:
The other solution of the given equation.
Solution:
We have,
\(x^2-64=0\)
It can be written as:
\(x^2-8^2=0\)
\((x-8)(x+8)=0\) \([\because a^2-b^2=(a-b)(a+b)]\)
Using zero product property, we get
\(x-8=0\) and \(x+8=0\)
\(x=8\) and \(x=-8\)
It is given that the one solutions is 8.
Therefore, the other solution is -8.
prove that 1·1!+2·2!+···+n·n!=(n+1)!−1 whenever n is a positive integer.
The statement holds for n=k+1.
By mathematical induction, we have proven that 1·1!+2·2!+···+n·n!=(n+1)!−1 for all positive integers n.
What are integers?
Integers are a set of numbers that include whole numbers (positive, negative, or zero) as well as their opposites.
We will use mathematical induction to prove the statement.
Base case: Let n=1. Then the left-hand side of the equation is 1·1!=1 and the right-hand side is (1+1)!=2!-1=1. Therefore, the statement holds for n=1.
Induction hypothesis: Assume that the statement holds for some positive integer k, i.e., 1·1!+2·2!+···+k·k!=(k+1)!−1.
Inductive step: We need to show that the statement also holds for k+1, i.e., 1·1!+2·2!+···+(k+1)·(k+1)!=(k+2)!−1.
We have:
1·1!+2·2!+···+k·k!+(k+1)·(k+1)!=k!+1·1!+2·2!+···+k·k!+(k+1)·(k+1)!=k!+(k+1)!−1+(k+1)·(k+1)!=k!(k+1+1)+(k+2)!−1=(k+1)!(k+2)−1=(k+2)!−1,
where we have used the induction hypothesis in the second step and simplified in the fourth step.
Therefore, the statement holds for n=k+1.
By mathematical induction, we have proven that 1·1!+2·2!+···+n·n!=(n+1)!−1 for all positive integers n.

Cycle of summer Olympics 4, cycle of USA Census10, if each of these events happend in the 2000, what is the year these both will happen again
The cycle of summer Olympics is 4 years while the cycle of the USA Census is 10 years. If these events happen in 2000, the year they both will happen again is 2020. Here's the explanation:
Cycle of summer Olympics 4: The summer Olympics is an international multi-sport event that happens every four years. It is organized by the International Olympic Committee (IOC). The first summer Olympics was held in Athens, Greece, in 1896. Since then, it has been held every four years. So, if it happened in 2000, the next cycle would be in 2004, then 2008, 2012, 2016, and finally 2020. So, the year summer Olympics will happen again is 2020.Cycle of USA Census10: The USA Census is a population count that happens every 10 years. It is conducted by the United States Census Bureau. The first census was conducted in 1790, and since then, it has been conducted every ten years. So, if it happened in 2000, the next cycle would be in 2010 and then 2020. So, the year the USA Census will happen again is 2020.Therefore, if both events happened in 2000, the year they both will happen again is 2020.

Find F'(x): F(x) = Sx 3 t^1/3 dt
The derivative of F(x) is \(F'(x) = x^{(1/3)\).
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.
Let's compute F'(x):
F(x) = ∫[0 to x] \(t^{(1/3)} dt\)
To differentiate the integral with respect to x, we'll use the Leibniz integral rule:
F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)
According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.
\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\) [applying the chain rule to the upper limit]
Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.
\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)
\(F'(x) = x^{(1/3)\)
Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

Find all the values of x such that the given series would converge.
\sum_{n=1}^\infty \frac{(4 x)^n}{n^{8}}
The series is convergent
from x= , left end included (enter Y or N): to x= , right end included (enter Y or N):
The series converges for x in the interval [-1, 1), with the left end included and the right end not included.
To find all the values of x for which the given series converges, we will use the Ratio Test. The series is given by:
\(\sum_{n=1}^\infty \frac{(4 x)^n}{n^{8}}\)
Let's apply the Ratio Test:
\(\lim_{n \to \infty} \frac{\frac{(4 x)^{n+1}}{(n+1)^{8}}}{\frac{(4 x)^n}{n^{8}}} = \lim_{n \to \infty} \frac{n^8 (4x)^{n+1}}{(n+1)^8 (4x)^n}\)
Simplify the expression:
\(\lim_{n \to \infty} \frac{4x n^8}{(n+1)^8}\)
Now, we need to find the values of x for which this limit is less than 1, as the Ratio Test states that the series converges if this limit is less than 1.
\(\frac{4x}{(1+\frac{1}{n})^8} < 1\)
Divide both sides by 4:
\(x < \frac{1}{(1+\frac{1}{n})^8}\)
As n approaches infinity, the term \(\frac{1}{n}\) approaches 0:
\(x < \frac{1}{(1+0)^8} = \frac{1}{1}\)
So, for the series to converge, x must be less than 1.
The series is convergent from x = -1, left end included (Y) to x = 1, right end not included (N).
Your answer: The series converges for x in the interval [-1, 1), with the left end included and the right end not included.

1. Anne wants to join five pieces of paper together. She plans to use 3 rectangular pieces of the same size and 2 square pieces of the same size. The length of each rectangular piece is 3 1/2 feet. The width of each rectangular piece, w, is the same as the length of each square piece. The expression below can be used to find the total surface area of the five pieces of paper. Anne decides that the width, w, of the rectangular pieces should be 2 feet. What is the total surface area, in square feet, of all five pieces of paper?
Answer and explanation:
Surface area of a rectangle = length * width
Surface area of a square = a² where a is length of a side
To find total surface area of the the five pieces of paper, we add up all the areas of all the shapes
Given that length of rectangle =3.5
And width = 2
Area of rectangle =3.5*2=7
Area of 3 rectangles given they are all equal = 7*3=21
Since width of rectangle equal to width of square and all sides of square are equal
Area of square = 2 *2 =4
Area of the two squares =4*2=8
Total surface area of the five plane shapes = 21+8= 29

Step-by-step explanation:
The degree of a polynomial is the highest power of its variables. For example, in the polynomial 4x^3 + 2x^2 - 5x + 7, the degree is 3 because x^3 is the term with the highest degree. The degree of a constant polynomial, such as 7, is 0. In general, if a polynomial has n terms, its degree is the degree of its leading term (the term with the highest degree).

Given the information Geometry in the question and assuming appropriate triangle arrangements, the possible true statements based on congruence postulates might include: ∆ACF≅∆ECF by HL, ∆ACB≅∆DFC by SSS, and ∆BFA≅∆DFE by SAS.
The provided question appears to pertain to geometric proofs, specifically in relation to triangles and the principles of congruency. Without a proper diagram, it's somewhat difficult to clarify, but based on the clues given, we can touch on some general principles.
Given that ZBCD is a right angle, BC=DC, DF=BF, FA = FE, the most applicable congruence postulates could be Hypotenuse-Leg (HL), Side-Side-Side (SSS), or Side-Angle-Side (SAS). These are all used to prove that triangles are congruent.
So, if we presume the statements to be: ∆ACF≅∆ECF by HL, ∆ACB≅∆DFC by SSS, and ∆BFA≅∆DFE by SAS, these could possibly be correct given the appropriate conditions in the diagram.
Remember: HL can only be applied in right triangles whereas SSS and SAS can be applied without the right angle requirement. All require the triangles to share at least one side or angle.
