In AON networks, "node" is a point where one or more lines (arrows) begin or terminate, commonly used for depicting an event or activity.
What is Activity-on-Node (AON) diagram?Scheduling logic diagrams of the most fundamental kind. Any activity on the schedule that has no float; Total Float = 0; is considered a critical activity.
Between the project's start and finish, there are vital activity(s) that must be completed continuously. This is known as the critical path.
The importance of AON diagram are-
Because it helps identify the essential path, the arrow diagram is crucial for the project timeline. The critical route is used to determine the most effective schedule while still achieving the objectives required for a project to be successful. The critical path indicates the longest time of every dependent task.It is possible to organize tasks and determine not only when they must be finished but also which ones must be performed and which ones can be skipped while still reaching the project's goals and objectives by creating a schedule. An arrow diagram is essential because of this. It results in the project's ideal schedule.To know more about the AOA and AON networks, here

Find the perimeter of the rhombus below, given that a = 7 and b = 14. (round your answer to one decimal place, if necessary.)
If the value of a is 7, b is 14 in the rhombus then the perimeter of the rhombus is equal to 31.3 units.
Given that the value of a is 7,b is 14.
We are required to find the perimeter of the rhombus.
The values which are given to us are of the lengths of diagonals of rhombus.
Perimeter of the rhombus is equal to 4 times the side of the rhombus. So in order to find the perimeter of the rhombus we need the side of the rhombus not the diagonals.
When we draw the diagonals in the rhombus it forms four right angled triangle in which the Base is equal to 7/2 units and 7 is the perpendicular.
We have to use pythagoras theorem to find the hypotenuse which is the side of the rhombus.
Suppose base is BC , perpendicular is AB and hypotenuse is AC.
AC=[tex]\sqrt{7^{2} +7/2^{2} }[/tex]
=[tex]\sqrt{49+49/4}[/tex]
=[tex]\sqrt{245/4}[/tex]
=7.826
Perimeter of rhombus=4*side
=4*7.826
=31.304
After rounding off it will be 31.3 units.
Hence if the value of a is 7, b is 14 in the rhombus then the perimeter of the rhombus is equal to 31.3 units.

During a very cold winter, water pipes sometimes burst because:
The water pipe sometimes bursts in winter because of the flowing water getting transformed into freezing water due to drop in temperature and the volume increases creating more pressure on the wall pipes.
Bursting of Water Pipes During a Very Cold Winter
The straightforward explanation is that during very cold winters, as water freezes into ice, it expands, causing solid ice to fill a larger volume than the liquid that was previously flowing through the pipes.
As we know that, the pressure P increases with increase in volume, V, the increased volume of frozen water leads to increase in the pressure inside the pipe.
The pressure that the ice builds up inside the pipes could rupture the pipe walls.

The solution for the given equation X^3 + Y^2 = 971,028. So, option A is correct.
What are multiples?A multiple of a number is the number whose remainder is 0 when divided by the given number.
Consider 'a' as the multiple of a number 'n'.
Then, a ÷ n = b (and remainder = 0)
Calculation:It is given that,
X = largest 2-digit multiple of 3 which is not a multiple of 5
⇒ X = 99
Y = smallest 2-digit multiple of 9 which is not a multiple of 6
⇒ Y = 27
Then, substituting the values in the given equation,
= X^3 + Y^2

A boss plans a business meeting at Starbucks with the two engineers below him. However, he fails to set a time, and all three arrive at Starbucks at a random time between and p.m. When the boss shows up, if both engineers are not already there, he storms out and cancels the meeting. Each engineer is willing to stay at Starbucks alone for an hour, but if the other engineer has not arrived by that time, he will leave. What is the probability that the meeting takes place
The probability that the meeting takes place is 7/24.
What is the probability?Probability is defined as the ratio of the number of favorable outcomes of an event to the total number of possible outcomes(sample space) of the event.
It is given by
P(A) = n(A)/n(S)
Where A - event, S - sample space
Calculation:From the given data,
The probability, if the engineers arrive in the first hour and the boss arrives in the second hour is 1/8,
So, the meeting will be held i.e., p = 1.
The probability, if all the three arrive in the same hour (first or second)
= 1/8 + 1/8
= 1/4
So, the meeting will be held only if the boss (he may arrive first, second, or last) arrives last, the probability is 1/3
The probability, if one of the engineers arrives in the first hour while the other engineer and the boss arrive in the second hour is
= 1/4
So, the meeting will be held only if the second engineer arrives before the boss and before the first engineer leaves, the probability is 1/3
Thus, the final probability for the meeting to take place is
= (1/8) × 1 + (1/4) × (1/3) + (1/4) × (1/3)
= 7/24
Therefore, the required probability is 7/24.

a. Angle a = 72.54 degrees
b. Hence find, in centimetres correct to one decimal place, the length of a
taut belt around the two pulleys
The length of the belt around the two pulleys is approximately 49.2 centimeters.
How to determine the length of the belt around the two pulleys?
In this question we must determine the perimeter of a belt around two pulleys, whose centers are 10 centimeters apart. This perimeter is the sum of part of the circumference of small pulley, part of the circumference of the big pulley and two times the segment tangent to the two pulleys.
Now we proceed to determine the parts of the perimeter of the belt:
Big pulley
s' = (214.92° / 180°) · π · (6 cm)
s' ≈ 22.506 cm
Small pulley
s'' = (145.08° / 180°) · π · (3 cm)
s'' ≈ 7.596 cm
Tangent segments
l = (10 cm) · sin 72.54°
l ≈ 9.539 cm
Lastly, the perimeter of the belt is:
L = s' + s'' + 2 · l (1)
L = 22.506 cm + 7.596 cm + 2 · (9.539 cm)
L = 49.180 cm

Is it possible to make a number out of 8 different digits that is
divisible by each of the eight digits?
Answer:
1,123,449,768
Step-by-step explanation:
The smallest number composed from 8 different digits that is divisible by each of those digits appears to be the 10-digit number ...
1,123,449,768
RestrictionsIf the number is to be divisible by an even digit, it must be even. That means it cannot end in the digit 5, so 5 cannot be one of the digits. We disallow division by 0, so 0 cannot be one of the digits.
The remaining 8 digits total 40, so cannot form a number divisible by 3, 6, or 9. In order to make such a number, we must add 5 to the digit total, but cannot do so using the single digit 5.
Choices for added digits include {1, 4} and {2, 3}. Adding 9+5 = 14 to the digit total would also work but would guarantee the resulting number is not the minimum possible.
Further divisibility restrictionsThe digits we have to work with are now {1, 1, 2, 3, 4, 4, 6, 7, 8. 9}. We know that an even number constructed from these digits will be divisible by 1, 2, 3, 6, and 9. To make it divisible by 4, 7, and 8, it must be a multiple of the LCM of those numbers.
The least possible number will use the smallest digits first, so will start ...
112344...
The remaining digits, 6, 7, 8, 9, need to form a number that will be divisible by 56 when appended to the 6 digits already used. Those 6 digits form a number, 1123440000, that has a remainder of 32 when divided by 56. Hence we need to use the digits 6, 7, 8, 9 to make a number with a remainder of 24 when divided by 56. There are 24 permutations of the digits 6, 7, 8, 9. Half of these are odd numbers
The one number formed from digits 6, 7, 8, 9 that is divisible by 56 with a remainder of 24 is 9768.
Smallest NumberThe smallest number comprised of 8 different digits and divisible by each of them is the 10-digit number 1,123,449,768.

A car can travel 161 miles on 7 gallons of gas. how much gas will it need to go 368 miles?
Answer:
16 gallons of gas
Step-by-step explanation:
Two ways to answer this
1:
Find how many miles per gallon the car can go. Then, divide the amount the car needs to go with the miles per gallon. This gets you the gallons of gas needed to go the amount. In this case, 161 ÷ 7 = 23. 368 ÷ 23 = 16.
2:
Make a proportion. [tex]\frac{161}{7} = \frac{368}{x}[/tex]. Solve for x. 161 and 7 cancel out to get 23. [tex]\frac{23}{1} = \frac{368}{x}[/tex]. Now you can either divide 368 and 23 and multiply the quotient by 1 to get x, or you can cross multiply to get an equation you can solve. In the first case, 368 ÷ 23=16. 1*16=16. x=16. In the second case, 23x=368. Divide both sides by 23 and you get x = 16.
