You buy a pair of jeans at a department store.
What is the percent of sales tax to the nearest tenth of a percent?
The price of the jeans includes a 60% markup. After the discount, what is the percent of markup to the nearest percent?
Answers
The price of the jeans before the discount is $24.99. The sales tax rate is 6.5%. The percent of markup after the discount is 27.7%.
The price of the jeans before the discount can be found by dividing the total cost by the markup percentage plus 100% and then multiplying by 100%.
So, the price of the jeans before the discount is (39.99 / 160) * 100 = 24.994375.
Next, to find the sales tax, multiply the subtotal by the sales tax rate.
The sales tax rate can be found by dividing the sales tax amount by the subtotal and then multiplying by 100%.
So, the sales tax rate is (1.95 / 29.99) * 100 = 6.502167.
To find the percent of markup after the discount, divide the difference between the total cost and the price before the discount by the price before the discount and then multiply by 100%.
So, the percent of markup after the discount is ((31.94 - 24.994375) / 24.994375) * 100 = 27.67322.
The probable question may be:

The price of the jeans includes a 60% markup. After the discount, what is the percent of markup to the nearest percent?
Department store
Jeans =39.99
Discount =-10.00
Subtotal =29.99
Sales tax=1.95

What you put on social media matters. Why does it matter and how will you ensure your social media postings reflect you professionally?
Answers
Answer:
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
As a professional what you put on social media matters a lot. Social Media postings show all what you are thinking or doing to hundreds, thousands, or even millions of people. If you are an artist you depend on those people (fans) to continue supporting you and your art so a single wrong post can turn a lot of people against you.
If you work for a company you are not only representing yourself through your posts but the company as well. This is because a company hires you for the person that you are therefore it is seen through the public eye that they share your way of thinking.
The best way for your postings to reflect you professionally, is to post only things relating to your own career and journey. While leaving out any opinions, personal information, and controversial topics.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
What is the probability that x is between $34 and $38?
Answers
The probability that ( x) is between $34 and $38 is 0.6826 or 68.26%.
To find the probability that a random variable ( x) is between $34 and $38, we need to use the probability density function (PDF) if ( x) follows a continuous distribution. Let's assume ( x ) follows a normal distribution with a mean [tex](\( \mu \))[/tex] of $36 and a standard deviation [tex](\( \sigma \))[/tex] of $2.
Calculate the z-scores for $34 and $38:
[tex]\[ z_1 = \frac{34 - 36}{2} = -1 \][/tex]
[tex]\[ z_2 = \frac{38 - 36}{2} = 1 \][/tex]
Look up the z-scores in the standard normal distribution table:
[tex]\[ P(z_1 < Z < z_2) = P(-1 < Z < 1) \][/tex]
Find the probabilities corresponding to these z-scores:
[tex]\[ P(Z < 1) = 0.8413 \][/tex]
[tex]\[ P(Z < -1) = 0.1587 \][/tex]
Subtract the two probabilities:
[tex]\[ P(-1 < Z < 1) = P(Z < 1) - P(Z < -1) = 0.8413 - 0.1587 = 0.6826 \][/tex]
So, the probability that ( x) is between $34 and $38 is 0.6826 or 68.26%.
The value of n is both 5 times as much as the value of m and 36 more than the value of m. What are the values of n and m? Explain.
Answers
n = m + 36
Both equations are equal to n so they equal each other. Solve for m
5m = m + 36
5m - m= m + 36 - m
4m = 36
4m/4=36/4
m = 9
Solve for n by inputting value of m into the given equations.
n = 5m ........................ n = m + 36
n = 5 (9) ....................... n = 9 + 36
n = 45 ........................... n = 45
They match so it's Correct!
m = 9
n = 45

The value of f is 0.02.
What is an expression ?Expression is a formation of numbers and variables with mathematical operations.
According to the given question we have to solve for f or we can say we have to find the value of f for the given expression which is
2+1.25f=10−2.75f (lets multiply each term by 100 to remove
decimals )
∴ 200 + 125f = 1000 - 275f
125f + 275f = 1000 - 200
400f = 800
f = 800/400
f = 2.
As we have multiplied by 100 we have to divide by 100 we obtain the exact result.
So, 2/100 is = 0.02
f = 0.02.

Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇f. if it is not, enter none. f(x, y) = (yex + sin y) i + (ex + x cos y) j
Answers
[tex]f(x,y) = (y \ e^{x} + sin(y) \hat{i} + (e^{x}+x \, cosy) \hat{j}[/tex]
Note that if the field is of the form
[tex]\vec{f} = P\hat{i} + Q\hat{j}[/tex]
then the condition for the field to be conservative is that
[tex] \frac{\partial P}{\partial y} = \frac{\partial Q}{\partial x} [/tex]
For the given field,
[tex] \frac{\partial P}{\partial y} =e^{x} + cos y \\ \frac{\partial Q}{\partial x} = e^{x}+cosy [/tex]
Because the condition is satisfied, the given field is conservative.
To find the function that satisfies
[tex]f= \bigtriangledown f[/tex]
[tex]f(x,y) = \int P(x,y)dx = ye^{x} + x\, siny + g(y)[/tex]
Because [tex] \frac{\partial P}{\partial y} = \frac{\partial Q}{\partial x} [/tex], therefore
[tex] \frac{\partial f}{\partial y} =e^{x} + x \, siny + g'(y)[/tex]
Because [tex] \frac{\partial f}{\partial y} =Q = e^{x} + x \, cosy [/tex]
therefore
g'(y) = 0
g = c (constant).
Answer:
(a) The given function is conservative.
(b) The function is
[tex]f(x,y) = ye^{x} + x \, siny + c[/tex]
where c = constant.
The vector field f(x, y) = (yex + sin y) i + (ex + x cos y) j is conservative because its curl vanishes everywhere. The function F such that ∇F = f is yex + cos y + C.
Explanation:To determine if the given function f(x, y) = (yex + sin y) i + (ex + x cos y) j is a conservative vector field, we need to see if the curl of the vector field vanishes everywhere. The curl of a vector field in two dimensions is the partial derivative of the j component with respect to x minus the partial derivative of the i component with respect to y.
For f(x, y), the partial derivative of the j component (ex + x cos y) with respect to x is ex + cos y, and the partial derivative of the i component (yex + sin y) with respect to y is ex + cos y. Both derivatives are equal, implying the curl is zero. Hence, f(x, y) is a conservative vector field.
Next, to find a function F such that ∇F = f, we need to integrate. The potential function, F, can be obtained by integrating the i component of f with respect to x (since it does not involve y), and the j component of f with respect to y (since it does not involve x): ∫yex dx + ∫sin y dy = yex + cos y + C. This is the function F such that ∇F = f.

Let a and b be events in a sample space s such that p(a) = 0.41, p(b) = 0.46 and p(a ∩
b.= 0.14. find p(a | b).
Answers
The conditional probability that event a will occur given that event b has occurred, denoted as p(a | b), is approximately 0.3 or 30%.
Explanation:The question is asking for the conditional probability of the event a given that event b has occurred, written as p(a | b). In probability theory, the formula for conditional probability is p(a | b) = p(a ∩ b) / p(b). Here, we already know that p(a ∩ b) = 0.14 and p(b) = 0.46. Substituting these values into the formula gives us:
p(a | b) = 0.14 / 0.46 = 0.304347826.
So, the probability of event a occurring given that event b has occurred is approximately 0.3 or 30%.

C.Increasing
D.Quadratic
Answers
Answer:
B. Decreasing
Step-by-step explanation:
We have been given formula of a function [tex]F(x)=9\cdot (\frac{1}{7})^x[/tex]. We are supposed to determine the type of our given function.
We know that an exponential function is in form [tex]y=a\cdot b^x[/tex], where,
a = Initial value,
b = If [tex]b>1[/tex], then the function is growth function. If [tex]b<1[/tex], then the function is decay function.
Upon looking at our given function we can see it is in form of exponential function.
Upon comparing our given function with standard exponential function, we can see that the value of a is 9 and value of b is [tex]\frac{1}{7}[/tex].
Since [tex]\frac{1}{7}<1[/tex], therefore, our function is decreasing and option B is the correct choice.
