You are paid $10.65/hr. Your deductions are FICA (7.65%), federal tax withholding (9.9%), and state tax withholding (7.35%). Your housing and fixed expenses are $493.68/month. How many hours per month must you work to be sure those expenses are paid?
62 hours
64 hours
68 hours
66 hours
Answers
Answer:
The first option; You must work about 62 hours.
Step-by-step explanation:
The total percent that you pay in taxes is 24.9%.
That means that you keep 75.1% of the money that you earn. We can write the following equation to determine the number of hours, h, that it will take to earn 493.68.
0.751(10.65)h = 493.68
Just divide by 0.751 and 10.65 and you will get the number of hours needed.

You are ready to buy a house, and you have $31,000 for a down payment and closing costs. Closing costs are estimated to be 4% of the loan value. You have an annual salary of $36,000, and the bank is willing to allow your monthly mortgage payment to be equal to 28% of your monthly income. The interest rate on the loan is 6% per year with monthly compounding (0.5% per month) for a 30-year fixed rate loan. How much money will the bank loan you?
Answers
Answer:
$ 140,104.96
Step-by-step explanation:
The amount the bank will the individual is the present value of the total mortgage payment.
monthly mortgage payment=28%*$36,000/12=$840
the payment is meant for 30 years but 360 months i.e 12*30
the amount of loan is the present value of $840 monthly for 360 months with 0.5% interest rate per month
=pv(rate,nper,-pmt,fv)
rate is 0.5%
nper is 360 months
pmt is $840 per month
fv is the total payments which is unknown
=pv(0.5%,360,-840,0)=$140,104.96
The loan amount is closest to $ 140,104.96
Write a 3×3 matrix A which A^2 is diagonal while A is not diagonal ?
Answers
Consider the matrix
[tex]A=\begin{bmatrix}0&1&0\\1&0&0\\0&0&1\end{bmatrix}[/tex]
Multiplying A by itself has the effect of swapping the first and second rows:
[tex]A^2=\begin{bmatrix}1&0&0\\0&1&0\\0&0&1\end{bmatrix}[/tex]
which is diagonal, while A itself is not.

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50 a plus 3.75 b equals 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?
Answers
Answer:
168 adult tickets were sold
Step-by-step explanation:
Multiply the amount of students by the cost of the student ticket (82 times 3.75) which equals 307.5 . Subtract that from the total amount earned (2071.5) and you get 1764. Divide that by the cost of an adult ticket (10.50), and you'll get the amount of adults who attended, which is 168.

168 Adult tickets were sold

Let A, P, and D by n x n matrices. Mark each statement true or false. Justify each answer.
a. A is diagonalizable if A = PDP^-1 for some matrix D and some invertible matrix P. Choose the correct answer below.
O The statement is true because the columns of P are the n linearly independent eigenvectors of A.
O The statement is false because A must have n distinct eigenvalues for the matrix D and P to exist.
O The statement is true because if A = PDP^-1, then A is diagonalizable by definition.
O The statement is false because the symbol D does not automatically denote a diagonal matrix.
Answers
Answer:
Correct answer is the 4th answer.
Step-by-step explanation:
By definition, a matrix is called diagonalizable if there exists some invertible matrix P and a diagonal matrix D such that AP = PD, which is equivalent to having A = PDP^-1.
We are not told that D is a diagonal matrix, hence, it could be any matrix. If A=PDP^-1 for some matrix D that is not diagonal, it doesn't imply that A is diagonalizable. Consider the following case: Let us take A a non diagonalizable matrix. Take D = A and P = identity matrix of size n. Then, this equation holds, but A is still not diagonalizable.
How are the functions f (x) = 16 Superscript x and g (x) = 16 Superscript one-half x related

g(x) is f(x) expanded horizontally by a factor of 2
Step-by-step explanation:
Given:

Replacing x in a function with x/k expands the graph horizontally by a factor of k. Here, it seems we have ...
g(x) = f(x/2)

Answer:
C. How tightly the molecules in a glass of water are packed together
Step-by-step explanation:
Volume of a substance is different according to the state of the matter.
So for a water molecule, the volume of the the water is definite and can be measured by the container which is the glass cup
So volume can be the measure of how tight the molecule of that substance ate together.

A rectangle has a length of x + 2 and a width of x-2, and
has an area of 60 square units. Find the length and width
of the rectangle.
Answers
Answer:
L = 10, W = 6
Step-by-step explanation:
(x-2)(x+2) = 60
[tex]x^{2}[/tex] - [tex]2^{2}[/tex] = 60
[tex]x^{2}[/tex] = 60 + 4 = 64
x = [tex]\sqrt{64}[/tex] = 8 or -8
-8 rejected
thus length is 8 + 2 = 10, width is 8-2=6
The length is 10 units and width is 6 units.
Length = x+2
Width = x-2
Area = 60
Area = Length × Width
Therefore, (x+2)(x-2) = 60
x²-2x+2x - 4 = 60
Collect like terms
x² = 60+4.
x² = 64.
Therefore, in order to get the value of x, we'll find the square root of 64
x² = 64.
x = ✓64
x = 8
Length = = x+2 = 8+2 = 10
Width = x-2 = 8-2 = 6
In conclusion, the length is 10 units and width is 6 units.

In a certain Algebra 2 class of 23 students, 11 of them play basketball and 13 of them play baseball. There are 8 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answers
Answer:
9/23
Step-by-step explanation:
Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.
___
Let A represent basketball, and B represent baseball. Then ...
P(A or B) = P(A) +P(B) -P(A and B)
Since 8 students play neither sport, we have ...
1 -8/23 = 11/23 +13/23 -P(A and B)
15/23 = 24/23 -P(A and B)
P(A and B) = (24 -15)/23
P(A and B) = 9/23

The perimeter of △PQR is 44 cm, and △PQR ~ △WXY. If PQ = 12 and XY + WY = 24, what is the perimeter of WXY? Complete the explanation.
Since the perimeter of △PQR = 44, QR + PR = 44 − PQ, or ____ cm. This is proportional to the sum XY + WY, because the two triangles are (similar or congruent)
so their corresponding sides are (not proportional or proportional). Their ratio is 24:__ , or 3:__ , which is the same ratio as their perimeters, 3/___ = P/44, so P = ___ cm.
Answers
Answer:
Since the perimeter of ΔPQR = 44, QR + PR = 44 - PQ, or 32 cm. This is proportional to the sum XY + WY, because the two triangles are similar so their corresponding sides are proportional. Their ratio is 24:32 or 3:4, which is the same as their perimeters, 3/4 = P/44, so P = 33 cm.
Step-by-step explanation:
The given parameters are;
ΔPQR ~ ΔWXY
Perimeter of ΔPQR = 44
PQ = 12
XY + WY = 24 based on position is proportional to QR + PR
However, the perimeter of ΔPQR = PQ + QR + PR = 44
Therefore, QR + PR = 44 - PQ = 44 - 12 = 32
Hence, XY + WY = 24 based on position is proportional to QR + PR = 32
If XY:QR = WY:PR we get (XY + WY):(QR + PR) (common factors)
∴ (XY + WY):(QR + PR) = 24:32 = 3:4
By extension, (WX + XY + WY):(PQ + QR + PR) = 3:4
Where: WX + XY + WY = P and PQ + QR + PR = 44 we have;
P:44 = 3:4 or 3/4 = P/44
From which P = 44 × 3/4 = 33 cm.
