How to write the set?We want to write the given set using set builder notation, the set is the set of all real numbers that are greater than or equal to 3 and less or equal to 9.
So the set can be written as an inequality as:
3 ≤ x ≤ 9
To define the set using the set builder notation, we also need to clarify that x belongs to the real number set, this is x ∈ R.
Then the set that we need to write is:

Answer:
(- 12, 10 )
Step-by-step explanation:
2x + 4y = 16 → (1)
- 2x - 3y = - 6 → (2)
add (1) and (2) term by term to eliminate x
0 + y = 10
y = 10
substitute y = 10 into (1) and solve for x
2x + 4(10) = 16
2x + 40 = 16 ( subtract 40 from both sides )
2x = - 24 ( divide both sides by 2 )
x = - 12
solution is (- 12, 10 )

Which of the given formulas for the general term of the sequence 8, 5, 2, –1, –4, ...
is correct?
a. tn = −3n + 11
b. tn = 3n + 11
c. tn = 3n + 8

The term is tn=-3n+11
From the question, we have
The sequence is 8, 5, 2, –1, –4, ...

The hourly rate that the business owner should pay the employees to obtain the desired net income of $40,000 is of:
$17.
How to calculate the net income?The net income is calculated as the subtraction of the total income by the expenses.
In the context of this problem, the expenses are given as follows:
Building and equipment: $900 a month = $10800 a year.Hearse: $200 per month = $2400 per year.Lead car: $150 per month = $1800 per year.Insurance: $1500 per year.Licensing/Certification: $250.Three employees, each working 20 hours a week = 52 x 20 = 1040 hours a year.Hence the expression for the net income is given as follows:
110000 - [10800 + 2400 + 1800 + 1500 + 250 + 3(1040x)] = 40000
93250 - 3120x = 40000
3120x = 53250
x = 53250/3120

The equation of line in the given graph with coordinate points (2,-2) and (-3,-6) is 4x-5y=18.
What is equation of line?A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. This value c is known as the y-axis intercept. Linear equations are classified into three types: point-slope, standard, and slope-intercept. The equation of a two-dimensional line is ax+by=c; it is fair to predict that the equation of a three-dimensional line is ax+by+cz=d; reasonable, but incorrect—it turns out that this is the equation of a plane. A plane, unlike a line, does not have a clear "direction."
Here,
The coordinates of line will be (2,-2) and (-3,-6).
slope m=(-6-(-2))/(-3-2)

HElp using trigonometry how do I solve this?
By using trignometry we got the side p as 6.67
Use the cosine rule of trignometry to find side p
p² = r² + q² - 2rqcosP
To find the angle of p we will simply subtract angle R and angle Q from 180.
180 - 47.28 - 40 = 92.72
p² = 8² + 7² + 2(8)(7)cos(92.72)
p² = 107.685
p = √107.685
p = 10.38
Let's suppose that the shortest distance of R from PQ is .
look at the diagram I gave
since the line I made makes a right angled triangle, we can use SOH CAH TOA
for the angle 40, is opposite and 10.38 is hypotenuse
which means we will have to use SOH
sin40 = O/H
sin40 =x /10.38
0.6428 = x/10.38
0.6428 × 10.38 = x
x = 6.67
Hence, by using trignometry we got the side p as 6.67

Using mathematical permutation, there 30240 number of 10-letter words that can be formed from the arrangement of letters cbqgvlbbgc
What is permutation?Permutation is simply the manner of arrangement or selection of elements.
We shall calculate for the permutation of the letters cbqgvlbbgc as follows:
There are total of 10 letters
c = 2
b = 3
g = 2
q = 1
v = 1 and,
l = 1
permutation of cbqgvlbbgc = 10!/(2! × 2! × 3!)
permutation of cbqgvlbbgc = (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3!)/(2! × 2! × 3!)

a certain species of bird migrates 10,000 miles in 75 days a person race walking can walk 20 kilometers in 100 minutes
who goes faster
A person race walking a distance of 20 kilometers in 100 minutes is more faster with a speed of 0.2 kilometer per minutes.
How to determine who is faster?Mathematically, the speed of a physical object or body can be calculated by using this formula;
Speed = distance/time
Next, we would convert the unit of distance covered by the bird in miles to kilometers as follows:
1 mile = 1.60934 kilometer.
10,000 miles = X kilometer.
Cross-multiplying, we have:
X kilometer = 10,000 miles × 1.60934 kilometer.
X kilometer = 16,093.4 kilometer.
Also, we would convert the unit of time in days to minutes as follows:
1 day = 1,440 minutes
75 days = X minutes
Cross-multiplying, we have:
X minutes = 75 days × 1,440
X minutes = 108,000 minutes.
Now, we can calculate the speed of this bird as follows:
Speed = 16,093.4/108,000
Speed = 0.1490 kilometer per minutes.
For the speed of the person, we have:
Speed = 20/100
Speed = 0.2 kilometer per minutes.

A basic cellular package costs $40 /month for 60 minutes of calling with an additional charge of $0.20 /minute beyond that time. The cost function C(x) for using x minutes would be
If you used 60 minutes or less, i.e. if if x≤60 , then C(x)=40 (the base charge).
If you used more than 60 minutes, i.e. (x−60) minutes more than the plan came with, you would pay an additional $0.20 for each of those (x−60) minutes. Your total bill would be C(x)=40+0.20(x−60) .
If you want to keep your bill at $50 or lower for the month, what is the maximum number of calling minutes you can use?
Answer:
78
exclamation is that if 50 is lower than 60 which it is meaning that 78 is the correct answer if you multiply 18 + 34 that is not the right answer but there should be a right answer under this question you shouldn't trust me because I do not give a what the answer is I do not suggest you write down this answer but you do your top G
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.
To keep your bill at $50 or lower for the month, you need to set up an inequality using the cost function C(x):
C(x) = 40 + 0.20(x - 60)
Since you want to keep the cost at or below $50, the inequality is:
C(x) ≤ 50
Now, substitute the expression for C(x) into the inequality:
40 + 0.20(x - 60) ≤ 50
40 + 0.20x - 12 ≤ 50
0.20x + 28 ≤ 50
Now, isolate the term with "x" on one side by subtracting 28 from both sides:
0.20x ≤ 50 - 28
0.20x ≤ 22
Finally, divide both sides by 0.20 to solve for "x":
x ≤ 22 / 0.20
x ≤ 110
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.

Now, we have the following expression:
2πr*27.28 = 200
54.56πr = 200
r = 200/54.56π
r = 200/54.56*3.14

then multiply 3 gallons by the 8 parts for the whole tank
3*8=24 gallons.
Than tank can hold 24 gallons
