Holly buys a $22 shirt for 20% off. The tax rate in her city is 6.5%. What is the total amount she paid for the shirt? Round to the nearest cent.
A.$2
B.$18.74
C.$24.10
D.$8.50
The total amount Holla paid for the shirt is: B. $18.74
Given the following data:
Cost of shirt = $22Discount = 20% Tax rate = 6.5%To find the total amount she paid for the shirt:
First of all, we would determine the discount on the shirt:
[tex]Discount = \frac{20}{100} \times 22\\\\Discount = 0.2 \times 22[/tex]
Discount cost = $4.4
[tex]Selling\; price = Cost\;price - Discount \\\\Selling\; price = 22 - 4.4[/tex]
Selling price = $17.6
Next, we would determine how much tax is to be paid:
[tex]Tax \;cost = \frac{6.5}{100} \times 17.6\\\\Tax \;cost = 0.065 \times 17.6[/tex]
Tax cost = $1.444
[tex]Total\;amount = selling \;price + tax\;cost\\\\Total\;amount = 17.6 + 1.444[/tex]
Total amount = $18.74

Step-by-step explanation:
you first change the mixed fraction into improper fraction after that you find the LCM .1 * 8 will give you 8 so you multiply 8 * 3 to get 24 8 will divide its self once so you will multiply 1 and11 to get 11 and subtract it from 24to get 13/8 and divide.write the equation of the ellipse using the given information: the ellipse has foci (0,3) and (0,-3) and major vertices (0,5) and (0,-5).
Answer: (x^2)/16 + (y^2)/25 = 1
Step-by-step explanation:
According to the problem we can figure out that the center of the ellipse is (0,0).
Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.
If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2
We get b^2 is 16
Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.

Hope it is helpful....What transformations take place by graphing the function below in respect to its parent function? Check all that apply.
Answer:
- Vertical Stretch
-Left 7 Units
-Up 2 units
Step-by-step explanation:
Because the formula is being multiplied by a number larger than 1, it is being vertically stretched. In this problem, it is being vertically stretched by a factor of 3/2.
When X is being added to in the parenthesis, it causes the graph to shift to the left. Since the equation has (X+7), the graph shifts left by 7 units.
When a number is added to the equation, it causes the graph to shift upwards. In this example, 2 is being added, therefore, the graph shifts upwards by 2 units.
That means there is a vertical stretch by a factor of 3/2, a horizontal translation left 7 units, and a vertical translation up 2 units

1. What is the difference between these two expressions
(5+3)*3
(5+3)*9
Answer:
The difference is one number is larger than the other.
Step-by-step explanation:
we are doing BOMDAS
so (5+3)*3
we start with the bracket first since we are dealing with BOMDAS
(5+3)*3 = 8*3
then we multiply the 8*3 which equals to 24
(5+3)*9
we start with the bracket first (5+3) equals to 8 and then we multiply the 8 by the 9 and the answer is 72
(5+3)*9
(5+3)= 8*9
= 72
between 24 and 72 the difference is 72 is larger

What are index forms?Index forms are described as mathematical forms that makes numbers or values in too small or too large forms appear in a more convenient manner.
Other names for index forms are standard forms and scientific notation.
These index forms are formed by taking the exponents of numbers or variables inside of their usually repetitive forms in an expression.
From the information given, we have that;

According to national data, about 15% of American college students earn a graduate degree. Using this estimate, what is the probability that exactly 27 undergraduates in a random sample of 200 students will earn a college degree? Hint: Use the normal approximation to the binomial distribution, where p = 0.15 and q = 0.85. (Round your answer to four decimal places.)
Using the binomial probability relation, the probability that exactly 27 graduates earn a college degree is 0.069
Using the relation :
P(x = x) = nCx * p^x * q^(n-x)
Probability of success, p = 0.15q = 1 - p = 1 - 0.15 = 0.85Number of trials, n = 200X = 27Probability of exactly 27 graduates can be defined thus :
P(x = 27) = 200C27 × 0.15^27 × 0.85^173
P(x = 27) = 0.0686264
Therefore, the probability of selecting exactly 27 graduates is 0.069

Slope = 9
Step-by-step explanation:
Point (3,27) and (5,45)
m = (45-27)/(5-3)
18/2 = 9
Answer:
9
Step-by-step explanation:
To find the slope of a line, one of the methods is to look for the rise over run, or the change in y over the change in x. If we just look at the first few numbers on the chart, we can see that the change in y (for the first two numbers) is 18, and the change in x (for the first two numbers) is 2. So our slope is 18/2, or 9.

In a certain university, there was a certain number of students who attended the general orientation. The number of male students was five times as many as that of female students. When 324 male students left the orientation, the number of female students became twice as many as that of male students. How many students attended the orientation?
Answer:
fewfefdfgtrusergwer h4yr sfd gw gr.
Step-by-step explanation:
The number of students who attended the orientation in that considered university was 432
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, first, let we assume the number of male students and female students who attended the orientation:
m = number of male students attending the orientationn = number of female students attending the orientationFrom the description, we have:
m = 5 times n = 5n
and
(m - 324)'s twice = n
or 2(m-324) = n
Thus, we get system of two equations as:
[tex]m = 5n\\2(m-324) = n[/tex]
Substituting value of m from first equation in second, we get:
[tex]2(5n - 324) = n\\10n -648 = n\\\\n = \dfrac{648}{9} =72[/tex]
Putting this value of n back in first equation, we get:
[tex]m = 5n = 5 \times 72 = 360[/tex]
Assuming that there were only two gendered students in university orientation (males and females), we get:
Total number of students who attended the orientation = m + n = 360 + 72 = 532
Thus, the number of students who attended the orientation in that considered university was 432

If E is the circumcenter of MNP, find each measure.
Answer:
NE = 37
MD = 3[tex]\sqrt{65}[/tex]
Step-by-step explanation:
NOTE: This explanation assumes you have basic knowledge of circumcenters, the Pythagorean Theorem, and pre-algebra
Assuming the calculations you so kindly did for us are correct:
To find NE
Simply plug x, which you found was 5, into the equations 13x-28, then you have the length of the line NE, which is 37.
So
NE = 37
To find MD
A little bit trickier, but still simple. You end up having to use the Pythagorean Theorem. Since NE = ME, you know that ME is equal to 37. Since triangle MED is a right triangle, and you're given on the the side ED (which is 28), and the hypotenuse, ME (which is 37), you can say that
28^2 + b^2 = 37^2
784 + b^2 = 1369
b^2 = 585
b = 3[tex]\sqrt{65}[/tex]
(In which b is MD)
So
MD = 3[tex]\sqrt{65}[/tex]
