lets write the possible subset of the following sets and list the proper subset separately
An improper subset of set T contains all the elements of set T and a null element. The improper subset of set T is {2,3}
What is a subset?In mathematics, set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be identical;
A) Integers are whole numbers (without fractions) that are either positive or negative. If T={x:X is an integer between 1 and 4}, therefore the elements in set T = {2, 3}
B) Since the elements in set T = {2, 3}, then the number of elements in set T = 2
C) The subsets of set T are {}, {2}, {3} and {2,3}
D) Proper subset of set T are subsets of T that is not equal to T. The proper subsets of T are {2} and {3}

5. Find the area of the figure below:
5 cm
4 cm
2cm
5 cm
Answer:
33 cm^2
Step-by-step explanation:
To find the are of the figure as a whole, find the area of each rectangle individually and then add them together.
The area of a rectangle is [tex]A = bh[/tex], so the area of the small rectangle would be [tex]4*2[/tex], or [tex]8cm^2[/tex].
The area of the larger rectangle would be [tex]5*5[/tex], or [tex]25cm^2[/tex].
So, adding those areas together, we get [tex]33cm^2[/tex] as the area of the whole figure.

Step-by-step explanation:
Donna earns $1,404 per week at her job. However, 19% of her income gets taken out in taxes, and 12% of her income gets taken out and put into her retirement account. Which is a reasonable estimate of the amount Donna is left with each week after the money is deducted?
Answer:
About 969 dollars
Step-by-step explanation:
I kind of did it the long way. I divided $1,404 by 100 and multiplied by 19. Did the same thing with 12. Added the product of those together and subtracted from 1,404.
(1,404÷100)19 + (1,404÷100)12 = 435.24
1,404 - 435.24 = 968.76
Since it was an estimate I rounded it to the nearest whole number and got 969

Suppose m QRS = 212°. Find the following.
(a) m/SQT =
(b) m/RQS =
Using the tangent theorem and the inscribed angle theorem, we have:
a. m∠SQT = 74°; b. m∠RQS = 16°.
What is the Tangent Theorem?Angle formed at the point of tangency between the tangent and the radius of a circle = 90 degrees based on the tangent theorem.
What is the Inscribed Angle Theorem?The inscribed angle theorem states that, measure of inscribed angle = 1/2(measure of intercepted arc).
a. Find m(SQT):
m∠RQT = 90° [tangent theorem]
m(QR) = 180° [semicircle]
m(QRS) = 212° [given]
m(RS) = m(QRS) - m(QR) = 212 - 180 = 32°
m∠RQS = 1/2[m(RS)] [inscribed angle theorem]
m∠RQS = 1/2(32)
m∠RQS = 16°
m∠SQT = m∠RQT - m∠RQS = 90 - 16
m∠SQT = 74°
b. m∠RQS = 1/2(32)
m∠RQS = 16°

Answer:
the last (4th) option
Step-by-step explanation:
the easiest way to find the right answer :
which of the 4 answers would deliver infinity for x = 5 ?
and that is only answer 4, as x = 5 creates 0 in the denominator of the fraction, which leads to the infinity break at that point in the functional curve.
other indications :
the smaller x, the more the denominator goes to -infinity, and the bigger x, the more the denominator goes to +infinity.
and that means the whole fraction goes to 0. and we are left for the function limit with the constant added at the end of the function.
looking at the graph, this has to be +3.
and again, only the 4th answer has "+3" at the end.
The function represented by the graph is y = 1(x - 5) + 3.
Option D is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The equation y = 1/(x - 5) + 3 represents a rational function with a vertical asymptote at x = 5.
This means that the graph of the function gets closer and closer to the vertical line x = 5, but never touches or crosses it.
The graph of the function also has a horizontal asymptote at y = 3.
This means that as x approaches infinity or negative infinity, the value of the function approaches 3.
The function has a y-intercept at (0, -4), where x = 0 and y = 1/(-5) + 3 = -4.
Thus,
The function represented by the graph is y = 1(x - 5) + 3.

Justin earns an annual salary of $48,000, which is paid monthly. This month Justin had the following deductions:
Federal and state income taxes
$650
Social Security and Medicare taxes
$248
Health insurance premiums
$350
Retirement plan contribution 5% of salary
What is Justin's net pay for the month?
Answer:
$2552
Step-by-step explanation:
First you have to find Justin's monthly salary. You do this by dividing his annual salary by 12 months. 48000/12 = 4000 This means Justin makes $4000 each month. Next we have to find what 5% of that is, in order to know how much his retirement plan contribution costs. To do this you divide 4000 by 100 to know how much 1% of his monthly salary is, and then you multiply that by 5 to know how much 5% of his monthly salary is. 4000/100 = 40 40x5 = 200 .We now know his retirement plan contribution each month costs $200. Now we need to know how much to subtract from his monthly salary to get his net pay for the month. We can do this by adding all of his monthly expenses together and then subtracting that total from 4000. 650+248+350+200 = 1448 4000-1448 = 2552 Justin's net pay for the month is $2552

Answer:
23.33
Step-by-step explanation:
The sum of the internal angles of a triangle is 180°, which is given by The Angle Sum Property of Triangles.
⇒ 3x - 17 + 2x + 5 + x + 52 = 180
⇒ 6x + 40 = 180
⇒ 6x = 140
⇒ x = 140/6
⇒ x = 70/3
⇒ x = 23.33
Answer: x = 23.333
In any triangle, all the three angles will ALWAYS add up to 180°. According to that:
▪ 180° = <a + <b + <c
(2x + 5) + (3x - 17) + (x + 52) = 180
2x + 5 + 3x - 17 + x + 52 = 180
Rearrange according to like terms
2x + 3x + x + 52 - 17 + 5 = 180
6x + 40 = 180
Now we'll find the value of x
6x = 180 - 40
x = 140/6
By cross cancellation we get
x = 70/3
You could change it into decimal as well
x = 23.333 answer
therefore, the third option that says 23.33 is correct.

the area is 72 square meters. the lenght is 9 meters. what is the width
Answer: 8 meters
Step-by-step explanation: 72/9 = 8
Answer:
8 meters
Step-by-step explanation:
Since there is so little information given, I'm assuming this is just the area of a rectangle. The formula you used to find the area of a rectangle is "area = length * width" or "A = l*w".
We are given the area and the length, so we can fill in those spaces in the formula-
72 = 9 * w
Now, in order to find the width. we have to undo in reverse order. We have to divide 72 by 9.
72 (/ 9) = 9 * w (/ 9)
8 = w
Therefore, the width is 8 meters. I hope this helps! Have a lovely day!! :)
The cost $C$ (in dollars) of making a square window with a side length of $n$ inches is represented by $C=\frac{n^2}{5}+175$
. A window costs $355. What is the side length (in feet) of the window?
The side length (in feet) of the square window which has the cost of making equal to $355 is 30 feet.
What is a mathematical model?A mathematical model is the model which is used to explain the any system, the effect of the components by study and estimate the functions of systems.
The cost (in dollars) of making a square window with a side length is C. the length of side of the window is n.
The model, which represent the cost of window in dollar, is,
C=(n²/5)+175
A window costs $355. Thus, C=355. Put this value in above model as,
355=(n²/5)+175
355-175=(n²/5)
180 x 5=n²
n=√(900)
n=30
Hence, the side length (in feet) of the square window which has the cost of making equal to $355 is 30 feet.
