A plumber worked 3. 5 hours for AED 1,075 in total. He added AED 200 for supplies to the customer's bill hourly rate of the plumber is AED 364.29.
How much is charged, paid, or earned for each hour worked?
Instead of paying for the things the advisers try to sell you, you pay a set or hourly charge for their time.
We must first deduct the price of the materials from the plumber's overall profits in order to get his hourly rate:
Income equals AED 1,075 plus AED 200, or AED 1,275.
After that, we may split his total income by the quantity of hours he put in:
Hourly fee is calculated as follows: AED 1,275 / 3.5 hours of work.
Hourly rate is 364.29 AED.
The plumber's hourly charge is therefore AED 364.29.

Solve the value for k:
[tex]\displaystyle{\lim_{x\to \infty} \left(1+\dfrac{65}{x}\right)^{3x} = e^k}[/tex]
The value of k in the exponential function is -3.
What is the value of k in the exponential function?
Taking the natural logarithm of both sides of the equation, we have:
ln [ (1 + 65/x)^(3x) ] = ln(e^k)
Using the properties of logarithms, we can simplify the left side of the equation:
3x ln(1 + 65/x) = k
Taking the limit as x approaches infinity, we have:
lim (x → ∞) 3x ln(1 + 65/x)
= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3
Using L'Hopital's rule, we can evaluate the limit:
lim (x → ∞) [ln(1 + 65/x) / (1/x)]
= lim (x → ∞) [-65 / (x(1+65/x))]
= -65/65
= -1
Therefore, we have:
lim (x → ∞) 3x ln(1 + 65/x)
= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3
= -3
Thus, the exponential equation simplifies to:

How do you prove that between any two irrationals there is a rational number and vice versa?
To prove that there exists a rational number between any two irrational numbers, we can use the fact that there exists a rational number between any two real numbers.
Let a and b be two irrational numbers with the property that a b. Then a and b are not rational by definition, which means they cannot be written in the form p/q, where p and q are integers and q is not equal to zero.
We can define a new number c = (a + b) / 2 because a b. This number is a rational number because it can be expressed as a fraction in lowest terms as (a + b) / 2.
As a result, we have demonstrated that a rational number c exists between any two irrational numbers a and b.
A similar argument can be used to demonstrate that there exists an irrational number between any two rational numbers.
Consider a and b to be two rational numbers such that a b. We can then define a new number c = (a + b) / 2.
If c is also rational, we're done because we can just use c as our desired number between a and b. However, if c is irrational, we have found our desired number between a and b, which is also irrational.
Assume that a and b are both even integers to see why c must be irrational in some cases. Then their average c is also even, implying that c can be written as p/q, where p and q are integers and q is not equal to zero, with both p and q being even. However, because p and q are both even, this contradicts the fact that they must have no common factors.
As a result, we have demonstrated that there exists an irrational number c between any two rational numbers a and b.

Find the value of each trigonometric ratios
Tan. X
It is important to note that this calculation provides the value of tan(x) in terms of the cosine of the angle x, which is dependent on the specific triangle that is being considered.
Given the triangle with sides ZY = 48, ZX = 50, and XY = 14, we can use trigonometry to find the value of tan(x).
First, we can use the Pythagorean theorem to find the value of YX, the length of the side opposite angle x:
[tex]YX = \sqrt{(ZY^2 + ZX^2 - 2 * ZY * ZX * cos(x))[/tex]
We know that ZY = 48 and ZX = 50, so we can substitute these values into the equation:
[tex]YX = \sqrt{(48^2 + 50^2 - 2 * 48 * 50 * cos(x))[/tex]
[tex]YX = \sqrt{(2304 + 2500 - 2400 * cos(x))[/tex]
Next, we can use the definition of tangent to find the value of tan(x):
[tex]tan(x) = YX/ZX = \sqrt{(2304 + 2500 - 2400 * cos(x)) / 50[/tex]
It is important to note that this calculation provides the value of tan(x) in terms of the cosine of the angle x, which is dependent on the specific triangle that is being considered. The exact value of tan(x) will depend on the specific angle x in the triangle.

1) What will be the probability that no man will be selected
2)What is the probability that both men will get selected
3)If she gets one more resume of a woman, what is the probability that only one man gets selected
Answer: The probability that no man will be selected is the number of ways that only women can be selected divided by the total number of combinations of candidates for the 2 data analyst positions. There are 2 ways to choose 2 women from the 2 available women, and there are C(4,2) = 6 ways to choose 2 candidates from the 3 men and 2 women, so the probability that no man will be selected is 2/6 = 1/3.
The probability that both men will get selected is the number of ways to choose 2 men from the 3 available men divided by the total number of combinations of candidates for the 2 data analyst positions. There are C(3,2) = 3 ways to choose 2 men from the 3 available men, and there are C(5,2) = 10 ways to choose 2 candidates from the 3 men and 2 women, so the probability that both men will get selected is 3/10 = 3/5.
If Jyothi gets one more resume of a woman, there will be a total of 3 men and 3 women. The probability that only one man gets selected is the number of ways to choose 1 man and 1 woman from the 3 men and 3 women divided by the total number of combinations of candidates for the 2 data analyst positions. There are C(3,1) * C(3,1) = 9 ways to choose 1 man and 1 woman, and there are C(6,2) = 15 ways to choose 2 candidates from the 3 men and 3 women, so the probability that only one man gets selected is 9/15 = 3/5.

Calculate the correct dosage to be administered. Order: medication K 15 mg, intravenously
Supply: Medication K 10 mg/ 0. 5 ml
Give: ? ml
The correct dosage to be administered is 5 ml.
To calculate the correct dosage to be administered, we can use the following formula:
Dose = (Desired dose / Stock strength) x Stock volume
In this case, the desired dose is 15 mg and the stock strength is 10 mg/0.5 ml. Therefore:
Dose = (15 mg / 10 mg/0.5 ml) x Stock volume
Simplifying this expression, we get:
Dose = 3 x Stock volume
To find the stock volume needed, we can rearrange this formula as follows:
Stock volume = Dose / 3
Substituting the values we have, we get:
Stock volume = 15 mg / 3 = 5 ml

Find the value of x
please help!!
The measure of the angle x in the figure is 55 degrees
How to find the value of x.From the question, we have the following parameters that can be used in our computation:
The polygon and the external angles
The sum of the exterior angles of a polygon is 360°.
Using the above as a guide, we have the following:
5 * x + x + 30 = 360
Evaluate the like terms
So, we have
6x = 330
Divide by 6
x = 55
Hence, the value of x is 55

Gerald has markers and pens in his backpack. He has a total of 78. If he has 11 more markers and pens, how many markers does he have?
(Systems of equation)
The required number of markers does Gerald has 56 markers.
How to find markers does he have?Let's represent the number of markers that Gerald has with the variable "m", and the number of pens he has with the variable "p". We can set up two equations based on the information given:
According to question:m + p = 78 (equation 1)
(m + 11) + (p + 11) = 78 (equation 2)
In equation 2, we add 11 to both the number of markers and the number of pens, since Gerald has 11 more of each. We can simplify equation 2 by combining like terms:
m + p + 22 = 78
m + p = 56 (equation 3)
Now we have two equations with two variables. We can use either substitution or elimination to solve for one of the variables. Let's use substitution and solve for "m" in terms of "p" using equation 1:
m + p = 78
m = 78 - p
Now we can substitute this expression for "m" into equation 3:
m + p = 56
(78 - p) + p = 56
Simplifying the equation, we get:
78 - p + p = 56
78 = 56 + p
p = 22
Therefore, Gerald has 22 pens. To find the number of markers he has, we can substitute this value of "p" into equation 1:
m + 22 = 78
m = 56
So, Gerald has 56 markers.

On solving the provided question, we cans ay that in this triangle by Pythagorean theorem [tex]A^2 = B^2 + C^2[/tex] => AC = [tex]\sqrt{115}[/tex]
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.
here, in this triangle by Pythagorean theorem
[tex]A^2 = B^2 + C^2[/tex]

tyrone drew a logo and a dilation of the same logo on the coordinate plane. describe the dilation. then write a coordinate rule to represent it.
Dilation in coordinate geometry refers to the process of increasing or stretching the size of the originally drawn geometrical figure to a new figure by multiplying the co-ordinates of the original figure with a scale factor and obtain new co-ordinates to plot and form on the graph.
In the given figure, we observe that the original co-ordinates of the logo drew by Tyrone are:
A (-2,0) ; B (-2,3) ; C(2,2) ; D(2,-1)
From the graph, we see that the co-ordinates are multiplied by a scale factor of 5/2 and hence turn to new co-ordinates:
A'(-5,0) ; B'(-5, 15/2); C'(5,5) ; D'(5, -5/2)
Thus, we see that the rule followed to form the dilation of the logo on the coordinate plane was (5/2x, 5/2y).
