Another inequality that describes the solutions would be: x ∈ (4, ∞)

What is inequality ?

In mathematics, an inequality is a statement that compares two values, expressions, or quantities, and asserts that they are not equal. Inequalities are often expressed using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

The inequality 3x > 12 can be solved by dividing both sides by 3:

3x/3 > 12/3

x > 4

This means that all values of x greater than 4 are solutions to the inequality 3x > 12.

This notation represents the interval of all real numbers greater than 4, including 4 itself. The symbol "(" means that 4 is not included in the interval, while "∞" indicates that the interval extends indefinitely to the right.

Therefore, Another inequality that describes the solutions would be: x ∈ (4, ∞)

How to determine?

To find the area of each polygon, we need to use the formula for the area of each respective shape.

Assuming the polygons are rectangles, triangles, and trapezoids, we can find their areas as follows:

The area of the rectangle with length 9 ft and width 6 ft is A = length × width = 9 ft × 6 ft = 54 ft².

The area of the triangle with base 10 cm and height 115 cm is A = (1/2) × base × height = (1/2) × 10 cm × 115 cm = 575 cm².

The area of the trapezoid with bases 5 m and 8 m, and height 4 m is A = (1/2) × (base1 + base2) × height = (1/2) × (5 m + 8 m) × 4 m = 26 m².

The area of the triangle with base 3 cm and height 8 cm is A = (1/2) × base × height = (1/2) × 3 cm × 8 cm = 12 cm².

The area of the rectangle with length 1.5 m and width 5 m is A = length × width = 1.5 m × 5 m = 7.5 m².

The area of the trapezoid with bases 6 ft and 3 ft, and height 4 m is A = (1/2) × (base1 + base2) × height = (1/2) × (6 ft + 3 ft) × 4 m = 9 ft × 4 m = 36 ft².

Therefore, the unlock code is: 54-575-26-12-7.5-36.

The value of x is 18.4.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Given that,

sin (2x + 7)° = cos (3x - 9)°  [Equation 1]

We have the trigonometric rule that,

cos (θ) = sin(90 - θ)

So, cos (3x - 9)° = sin (90 - (3x - 9))

So from equation 1,

sin (2x + 7)° = sin (90 - (3x - 9))

Equating,

2x + 7 = 90 - (3x - 9)

2x + 7 = 90 - 3x + 9

2x + 7 = 99 - 3x

Mohal would expect to earn $265 in a day when he waits on 16 tables, and he would expect to earn $15tt + $25 in a day when he waits on tt tables

Earnings or wages refer to the amount of money an individual receives in exchange for their work or services. This can include a regular salary or hourly wage, as well as bonuses, commissions, and other forms of compensation.

Earnings or wages are typically determined by a variety of factors, including the type of work being performed, the level of skill and experience required, the local job market, and the employer's policies and practices. In some cases, earnings may be negotiated between the employer and the employee, while in other cases they may be set by industry standards or government regulations.

To calculate Mohal's expected earnings in a day when he waits on 16 tables, we can use the formula:

Total earnings = Guaranteed wage + Tips

Guaranteed wage = $25

Tips = $15 x Number of tables

Number of tables = 16

So, Total earnings with 16 tables = $25 + ($15 x 16) = $265

To calculate Mohal's expected earnings in a day when he waits on tt tables, we can use the same formula:

Total earnings = Guaranteed wage + Tips

Guaranteed wage = $25

Tips = $15 x Number of tables

Number of tables = tt

So, Total earnings with tt tables = $25 + ($15 x tt) = $15tt + $25

Therefore, Mohal would expect to earn $265 in a day when he waits on 16 tables, and he would expect to earn $15tt + $25 in a day when he waits on tt tables.

Step-by-step explanation:

The dimensions of the rectangle are: length: 20 units and width: 3 units.

To solve the problem, we can set up an algebraic equation using the formula for the area of a rectangle, which is A = length × width.

Let x be the length of the rectangle, and x - 17 be the width.

Then we can set up the equation:

60 = x(x - 17)

Simplifying the equation gives us:

x² - 17x - 60 = 0

Now we can factor the equation:

(x - 20)(x + 3) = 0

This gives us two possible solutions for x:

x = 20 or x = -3

However, since the length of a rectangle cannot be negative, we can disregard the second solution.

Therefore, the length of the rectangle is 20 units, and the width is 20 - 17 = 3 units.

Answer:

Dear Mary,

I understand your concerns about the cost of attending college and how it might not be worth it in the end. However, earning a college degree can significantly increase your earning potential and lead to greater job opportunities. In fact, individuals with a bachelor's degree earn an average of $1 million more over their lifetime compared to those with only a high school diploma. Moreover, pursuing a degree in chemical engineering can open doors to highly rewarding and well-paying career paths.

I agree that the published costs of attendance on college websites can be overwhelming, but keep in mind that these figures are often the maximum amount and many students receive financial aid to reduce their expenses. Financial aid comes in many forms, including scholarships, grants, work-study programs, and loans. Scholarships and grants do not have to be repaid, so it's worth exploring those options first. Loans can be daunting, but they can also be manageable if you borrow responsibly and budget accordingly.

It's understandable that you may feel uncertain about whether you qualify for financial aid or not, but it's always worth applying. Many families are surprised to find out that they qualify for aid that they didn't expect. The Free Application for Federal Student Aid (FAFSA) is the form used to determine your eligibility for federal and state financial aid, and it's free to complete. Private institutions may also require additional forms, so make sure to check each college's financial aid website for more information.

As for student loans, there are many repayment plans available, and you can choose one that works best for your budget. If you're having trouble finding a job after graduation, you can apply for deferment or forbearance to temporarily suspend your payments. It's important to have a plan in place for repayment, but it's also important not to let the fear of repayment stop you from pursuing your dreams.

I hope this information helps you make a more informed decision about your college plans. Remember, investing in your education can have long-lasting benefits and lead to a brighter future.

The answer to this question is as follows Given that this is a equation contradiction, 4C(-3) = 8 cannot be satisfied for any value of C. As a result, this equation cannot be solved.

A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.

4C(-3) = 8

The phrase 4C(-3), which calls for multiplying 4 by the value of C when it equals -3, has to be evaluated.

4C(-3) = 4 x C(-3) (-3)

We must now determine what C(-3) is. This requires entering -3 for the C expression:

C(-3)

By understanding that this phrase refers to the value of C when it is equal to -3, we can make it simpler. C(-3) thus equals 3.

When we add this value back into the formula, we obtain:

4C(-3) = 4 x C(-3) = 4 x (-3) = -12

But, because we were informed that 4C(-3) = 8, we have:

8 = -12

Given that this is a contradiction, 4C(-3) = 8 cannot be satisfied for any value of C. As a result, this equation cannot be solved.

The ordered pair (1,-3) is a solution to the given system, while the ordered pair (0,0) is not

practice is a great way to help you understand how to determine whether ordered pairs are solutions to a given system. In this case, we are looking at the system:

3x+y=0

x+2y=-5

To determine whether the ordered pairs (0,0) and (1,-3) are solutions, we need to plug them into the equations and see if they make the equations true.

For the first ordered pair (0,0), we plug in x=0 and y=0 into the equations:

3(0)+(0)=0

(0)+2(0)=-5

The first equation is true, but the second equation is not. Therefore, (0,0) is not a solution to the system.

For the second ordered pair (1,-3), we plug in x=1 and y=-3 into the equations:

3(1)+(-3)=0

(1)+2(-3)=-5

Both equations are true, so (1,-3) is a solution to the system.

The electric field outside the pipe is E(r) = σa² / ε_0r².

The electric field inside the pipe is E(r) = σa²/ ε_0r.

Assuming the metallic pipe is infinitely long, we can use Gauss's Law to determine the electric field both inside and outside the pipe.

Let's consider a cylindrical Gaussian surface of radius r and length L, with its axis coinciding with that of the pipe.

By Gauss's Law, the electric flux through the surface is given by:

Φ_E = ∫ E . dA = E x 2πrL

where;

The charge enclosed by the Gaussian surface is given by:

Q_enc = σ x π(2a)² x L

= 4πa²σL

where;

By Gauss's Law, the electric flux through the Gaussian surface is also given by:

Φ_E = Q_enc / ε_0

where;

Equating the two expressions for Φ_E, we get:

E x 2πrL = 4πa²σL / ε_0

Simplifying, we get:

E = σa² / ε_0r for r < a

E = σa² / ε_0r^2 for r > a

Therefore, the electric field inside the pipe (r < a) is inversely proportional to the distance from the axis, while outside the pipe (r > a) it is inversely proportional to the square of the distance from the axis.

To summarize:

Outside the pipe: E(r) = σa² / ε_0r²

Inside the pipe: E(r) = σa² / ε_0r

Step-by-step explanation:

Let's assume the number to be x.

According to the problem statement, the sum of a number and its reciprocal is 2 1/6 or 13/6.

So we can set up the equation:

x + 1/x = 13/6

Multiplying both sides by 6x, we get:

6x^2 + 6 = 13x

Bringing all the terms to one side, we get:

6x^2 - 13x + 6 = 0

We can solve for x using the quadratic formula:

x = [13 ± sqrt(13^2 - 4(6)(6))] / (2*6)

x = [13 ± sqrt(169)] / 12

x = [13 ± 13] / 12

So, x can be either 2/3 or 3/2. Therefore, the number is either 2/3 or 3/2.
