the hcf of 90 and x is 18. the lcm of 90 and x is 540. find the value of x.
The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
Hence, the value of x is 108.

if the complement of an angle is 62 then find its supplement
Answer:
supplement = 152°
Step-by-step explanation:
If the complement is 62° , then
angle = 90° - 62° = 28° ( Complementary angles sum to 90° )
Supplementary angles sum to 180° , then supplement of 28° is
180° - 28° = 152°
-3(2+ k)- 6k = 6+ 3k
Answer:
solve for k, k=-1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
k=-1
Step-by-step explanation:
First step: Distribute
Result: -6-3k-6k=6+3k
Second step: Combine like terms
Result: -6-9k=6+3k
Third step: Add 6 to both sides
Result: -9k=12+3k
Fourth step: Subtract 3k from both sides
Result: -12k=12
Final step: Divide by -12 to both sides
Result/Answer: k=-1

(17-20)Name the intersection of each pair of planes.
Use the figure at the right to help you find the answers.
17.) planes QRS and RSW
18.) planes UXV and WVS
19.) planes XWV and UVR
20.) planes TXW and TQU
A point of intersection of two or more planes is the point where the plane meet. The answers to the questions are:
17) Point S
18) Point V
19) Point V
20) Point T
A plane is a flat surface which lies or can either be considered with respect to the x- axis, y- axis or z- axis. An intersection of two planes implies the point where the two planes meet.
From the given figure, the given planes has their points of intersections. Thus, the intersection of the planes given in the question are as follows:
17) planes QRS and RSW - The point of intersection of these two planes is point S.
18) planes UXV and WVS - The two planes has the point of their intersection as V.
19) planes XWV and UVR - The point of intersection of the planes is V.
20) planes TXW and TQU - The two planes intersect at point T.
Each of these planes has to be considered separately before relating it to another plane.

Victor wants to see if positively greeting children as they enter the classroom reduces problem behaviors. He randomly assigns 10 second- and third-grade classrooms to one of two conditions: classes where the teacher greets each student by name and with a smile as they enter the classroom and classes where the teacher does not greet students. During a 4-week period, he asks teachers to track the number of problem behaviors per classroom on a daily basis via a strict protocol he has designed. What is the control group
The control group in the experiment are the classes where the teacher does not greet the students
A control group in an experiment is made up of groups of people that do not receive the experimental treatment.
The purpose of a control group is to allow the researcher study one variable at a time.
Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.
The experimental treatment here is positively greeting the students.
The group that do not receive this experimental treatment are referred to as the control group.
At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

i could be wrong but i did it in my head , but the equation is right . just do that in order
Answer:
( 0.5, - 1 )
Step-by-step explanation:
So here is the equation:
x2 + x1 / 2 For the x coordinate
y2 + y1 / 2 For the y coordinate
x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.
Thus:
4 + -3 / 2 = 0.5 x coordinate
2 + -4 / 2 = -1 y coordinate
So it becomes (0.5, -1)

Answer:
The average value of the function over its domain
Simplify (4+2i)(4-2i)
A. 20
B. 12
C. 16-4i
D. 16+4i
[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]
Answer:
A
Step-by-step explanation:
We want to simplify the expression:
[tex](4 + 2i)(4- 2i)[/tex]
Notice that this is the difference of two squares. That is:
[tex](a +b)(a-b) = a^2 - b^2[/tex]
We can let a = 4 and b = 2i. Hence:
[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]
Simplify:
[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]
(Note that i² = -1.)
In conclusion, our answer is A.
