We have given that monthly allowance of jack is 15$
He decides to save 15% of his monthly allowances
We have to calculate the saving of each moth.
Therefore,
we have to find the 15% in decimal form,
What is the formula for finding the percentage in decimal form:
[tex]decimal form =\frac{x}{100}[/tex]
Where x is in %
Therefore,
15%=15/100=0.15
Jack want to save 0.15 from his monthly allowance of 15$
Therefore,
15(0.15)=2.25
Therefore,

Annie's cafe borrows $6100 at 6% for 290 days. Find the total amount that must be repaid after 290 days. (Use a 365 day year.)
The total amount that must be repaid after 290 days is $6330.67.
Explanation:To find the total amount that must be repaid after 290 days, we can use the formula:
Amount = Principal + Interest
Principal is the amount borrowed, which is $6100. Interest is calculated using the formula:
Interest = Principal * Rate * Time
Since the loan is for 290 days, we need to convert it to years by dividing by 365:
Time = 290/365 = 0.7945 years
Plugging in the values, the interest is:
Interest = 6100 * 0.06 * 0.7945 = $230.67
Adding the principal and interest together, the total amount to be repaid is:
Total Amount = Principal + Interest = $6100 + $230.67 = $6330.67

If a one dollar bill is 0.0001 meters thick, how many meters tall would a stack of 4 trillion one dollar bills be?
Answer:
[tex]4*10^{8}\text{ meters}=400,000,000\text{ meters}[/tex].
Step-by-step explanation:
We have been given that a one dollar bill is 0.0001 meters thick. We are asked to find the height of a stack of 4 trillion one dollar bills.
We know that [tex]\text{1 trillion}=10^{12}[/tex]. To find the thickness of a stack of 4 trillion one dollar bills we will multiply 0.0001 by 4 trillion.
Let us convert 0.0001 into scientific notation as:
[tex]0.0001=1\times 10^{-4}[/tex]
[tex]\text{The height of 4 trillion one dollar bills}=4*10^{12}\times 1\times 10^{-4}\text{ meters}[/tex]
Using exponent property [tex]a^b\times a^c=a^{b+c}[/tex] we will get,
[tex]\text{The height of 4 trillion one dollar bills}=4*10^{12-4}\text{ meters}[/tex]
[tex]\text{The height of 4 trillion one dollar bills}=4*10^{8}\text{ meters}=400,000,000\text{ meters}[/tex]
Therefore, the stack of 4 trillion one dollar bills would be [tex]4*10^{8}\text{ meters}=400,000,000\text{ meters}[/tex].

what is the best definition for marginal cost?
Marginal cost is the additional cost incurred when producing one extra unit of a good or service.
Marginal Cost: Marginal cost is the change in total cost that occurs when the quantity produced is increased by one unit. It represents the cost of producing one more unit of a good, encompassing all additional costs required for that extra unit.
Example: If producing one more car necessitates building an additional factory, the marginal cost includes all costs associated with setting up the new factory.
Marginal cost is the additional cost of producing one more unit of a good or service.
To calculate marginal cost, you divide the change in total cost by the change in the quantity produced. Mathematically, it can be expressed as:
Marginal Cost = (Change in Total Cost) / (Change in Quantity)
This concept is crucial in economics and business for decision-making purposes. It helps firms determine the cost-effectiveness of increasing or decreasing production levels.
For instance, if a company is considering expanding its production, understanding the marginal cost allows it to assess whether the additional revenue from selling more units will outweigh the additional costs incurred.
It is also used to make pricing decisions and optimize resource allocation. In summary, marginal cost provides insight into how production decisions impact overall costs and profitability.

If p(a) = 0.50, p(b) = 0.60, and p(a intersection
b.= 0.30, what is the p(a union b)? enter your answer as a decimal rounded to two places.
The probability is 0.80.
To find the probability of the union of two events, calculate the sum of their individual probabilities and subtract the probability of their intersection.
The probability of the union of events A and B (P(A ∪ B)) can be calculated using the formula:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Given P(A) = 0.50, P(B) = 0.60, and P(A ∩ B) = 0.30, substitute these values into the formula to find P(A ∪ B) = 0.50 + 0.60 - 0.30 = 0.80

it is given that ln(y+1) - ln(y) = 1+3ln(x) . express y in terms of x in a form not involving logarithms
We transformed the logarithmic equation ln(y+1) - ln(y) = 1 + 3ln(x) into an algebraic expression, resulting in y = 1 / (e × [tex]x^3[/tex] - 1).
To express y in terms of x from the given equation ln(y+1) - ln(y) = 1 + 3ln(x), we can follow these steps:
Apply the logarithm property ln(a) - ln(b) = ln(a/b): ln((y+1)/y) = 1 + 3ln(x).Rewrite the right-hand side using exponentiation: ln((y+1)/y) = ln(e) + 3ln(x) = ln(e × [tex]x^3[/tex]).Since the natural logarithms are equal, set their arguments equal to get the equation without logarithms: (y+1)/y = e × [tex]x^3[/tex].Isolate y by solving the above equation: y + 1 = y × e × [tex]x^3[/tex], hence y = 1 / (e × [tex]x^3[/tex] - 1).This gives us the final expression of y in terms of x without involving logarithms.
According to the Rational Root Theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?
Answer:
All the potential root of f(x) are [tex]\pm 1,\pm7, \pm \frac{1}{3},\pm \frac{7}{3}, \pm \frac{1}{9},\pm \frac{7}{9}[/tex].
Step-by-step explanation:
According to the rational root theorem, all the potential root of f(x) are defined as
[tex]x=\pm\frac{p}{q}[/tex]
Where, p is factor of constant term and q is factor of leading coefficient.
The given function is
[tex]f(x)=9x^8+9x^6-12x+7[/tex]
Here, constant term is 7 and leading coefficient is 9.
Factors of 7 are ±1, ±7 and the factors of 9 are ±1, ±3, ±9.
Using rational root theorem, all the potential root of f(x) are
[tex]x=\pm 1,\pm7, \pm \frac{1}{3},\pm \frac{7}{3}, \pm \frac{1}{9},\pm \frac{7}{9}[/tex]
Therefore all the potential root of f(x) are [tex]\pm 1,\pm7, \pm \frac{1}{3},\pm \frac{7}{3}, \pm \frac{1}{9},\pm \frac{7}{9}[/tex].

How much interest is earned on $269 at 10% for five years?
The simple interest can be calculated using the formula:
[tex] I = \frac{PRT}{100} [/tex]
We are given :
Principal = $269
Rate of interest = 10%
Time = 5 years
Plugging the values in the formula:
[tex] I = \frac{269*10*5}{100} [/tex]
Interest = $134.5
The interest on the principal amount in 5 years at the rate of 5% will be equal to $134.5.
What is Simple interest?A quick and simple way to figure out interest on that money is to use the simple interest approach, which adds interest at the same rate for each daily cycle, and it is to the initial principal amount.
A way to figure out how much interest will be charged on an amount of money at a specific rate and for a specific duration of time is by using simple interest.
As per the question, the given data is,
Principle, P = $269
Rate, T = 10%
Time, T = 5 years
[tex]SI =(P*R*T)/100[/tex]
SI = (269 ×10 × 5)/100
SI = $134.5
Therefore, the interest earned in 5 years is $134.5.
