What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction
Answer:
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
Step-by-step explanation:
1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625
The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."
The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.
In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."
Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.
Mathematical representation: \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

Amber and Jessica go out for lunch. Amber’s lunch costs $11.70, and she tips 18%. Jessica’s lunch costs $12.30, and she tips 15%. Complete a true statement.
jessica paid [ 0.29 / 0.32 / 0.55 ] , [ more/ less ] than amber at lunch
Jessica paid more than Amber at lunch.
To find out, we first need to calculate the amount of tip each person left:
Amber's tip = 11.70 x 0.18 = $2.11
Jessica's tip = 12.30 x 0.15 = $1.85
Then we add the cost of the lunch and the tip for each person:
Amber's total cost = 11.70 + 2.11 = $13.81
Jessica's total cost = 12.30 + 1.85 = $14.15
So Jessica paid $0.34 more than Amber for lunch.

The volume of the triangular pyramid below is 99 units^3. Find the value of x.
Check the picture below.
so the pyramid has a base area of "B" and a height of "h", thus
\(\textit{volume of a pyramid}\\\\ V=\cfrac{Bh}{3} ~~ \begin{cases} B=\stackrel{base's}{area}\\ h=height\\[-0.5em] \hrulefill\\ B=\frac{1}{2}(x)(6)\\[1em] h=9\\ V=99 \end{cases}\implies 99=\cfrac{1}{3}\stackrel{B}{\left[\cfrac{1}{2}(x)(6) \right]}(\stackrel{h}{9}) \\\\\\ 99=\cfrac{1}{3}(3x)(9)\implies 99=9x\implies \cfrac{99}{9}=x\implies 11=x\)
Answer:
11
Step-by-step explanation:
The formula for a triangular pyramid is:
V = 1/3 × base area × height
(base area is base × height ÷ 2 so x × 6 ÷ 2)
99 = 1/3 × 6x/2 × 9 divide equation by 9
÷9 ÷9
3(11 = 1/3 × 6x/2) multiple equation by 3
(33 = 6x/2) multiple by 2
66 = 6x divide by 6
÷6 ÷6
11 = x
This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

b. 1/2
Step-by-step explanation:
Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.
a. PossibilitiesAs the tree diagram shows, the number of possible meals is ...
(possible meats)×(possible fruits)×(possible desserts)
= 3×2×2 = 12
There are 12 possible lunch options.
b. CookiesHalf the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:
P(no cookie) = 1/2

Additional comment
The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

Step-by-step explanation:
a) 0+4-4=0
b) 0-4+4=0
They are similar because they both end up in the same number and you are adding/subracting the same number. (They both cancel each other)
They are different because it goes in the negative value in the number line and when subracting they represent different values.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Modulus Property:
\(\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}\)

N + 8n2 - 17=
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62

Equation : 35 + 6.40t < 86.20
t = less than 8 hours
Step-by-step explanation:
If t equals the number of hours they can rent the room before going over their set limit, we would add the base amount (35) to the hourly (6.40t) less than 86.20.
So :
35 + 6.40t < 86.20
6.40t < 51.20 (subtract 35 on both sides)
t < 8 (divide 6.40 on both sides)
:)
Answer:
35 + 6.40t < 86.20
Step-by-step explanation:
So it says 35 plus fee of about 6.40 times a variable less than 86.20

10./Check for Reasonableness A store manager instructs his employees to mark up all items by 30%. A store clerk puts a price tag of $30 on an item that the store bought for $27. As an employee, you notice that this selling price is incorrect. a. Find the correct selling price. Round to the nearest dollar. b. What was the clerk's likely error?
Answer:
Therefore, the selling price of the item is $35.1. Also, the clerks didn't put enough of the amount up too.
Step-by-step explanation:
Find out the selling price.
To prove
As given
A store manager instructs his employees to mark up all the items by 30%. An item that the store bought for $27.
30% is written in the decimal form.
= 0.30
30% of the $27 = 0.30 × 27
= $8.1
Selling price of the item = Original price of item + 30% of the $27
= $27 + $8.1
= $ 35.1
