How to Calculate the Moment of Inertia for a Cylinder?
The moment of inertia (I) is a measure of an object's resistance to rotational motion around an axis. The moment of inertia of a cylinder can be calculated using the following formula:
I = (1/2) × m × r²
where:
I is the moment of inertia of the cylinder
m is the mass of the cylinder
r is the radius of the cylinder.
Here are the steps to calculate the moment of inertia for a cylinder:
Determine the mass of the cylinder. This can be done by weighing the cylinder on a scale or by using its density and volume. The formula for the mass of a cylinder is:
m = density × volume
Measure the radius of the cylinder. This is the distance from the center of the cylinder to its outer edge.
Substitute the values of m and r into the moment of inertia formula:
I = (1/2) × m × r²
Calculate the moment of inertia using a calculator.
Note that the moment of inertia of a hollow cylinder is different from that of a solid cylinder. To calculate the moment of inertia of a hollow cylinder, you need to subtract the moment of inertia of the hollow space from the moment of inertia of the solid cylinder using the parallel axis theorem.

Consumer surplus $5 as we solve the Q by given data
Consumer surplus is the difference between the consumer's willingness to pay and the price of the commodity.
Consumer surplus in economics, also called social surplus or consumer surplus, is the difference between the price a consumer pays for a commodity and the price the consumer is willing to pay in exchange for giving it up.
Producer surplus is the difference between the price of a commodity and the lowest price at which a seller is willing to sell it.
Consumer Surplus = Willingness to Pay - Price of the Good.

PLS HURRY! Q3. What is the slope and y-intercept of the linear function?
The slope is ___ and the y-intercept is ____ .
The required slope of the linear function is $30, and the y-intercept is $75.
What is slope-intercept equation of line?When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.
According to question:To find the slope of the linear function, we need to calculate the change in cost divided by the change in time.
Change in cost = $285 - $105 = $180
Change in time = 7 - 1 = 6
Slope = Change in cost / Change in time = $180 / 6 = $30
To find the y-intercept, we can use the point-slope form of a linear equation, y = mx + b, where y is the cost, x is the time, m is the slope, and b is the y-intercept.
Using the point (1, $105), we can substitute x = 1 and y = $105 into the equation and solve for b:
$105 = $30(1) + b
b = $105 - $30 = $75
Therefore, the slope of the linear function is $30, and the y-intercept is $75.
The linear function can be written as: y = $30x + $75, where x is the number of months of membership and y is the cost of the membership.

In an online game, you receive -3 points for every banana your character slips on during a race. The total points from slipping on bananas during one race were at most -27. When the character slips, it takes 2 seconds for him to resume the race. Write and solve an inequality to find the least number of bananas your character slipped on. At least how many seconds of race time
Answer: Let's call the number of bananas your character slipped on as "x". Then, the total points from slipping on bananas would be -3x. And since the total points from slipping on bananas during one race were at most -27, we can write an inequality to represent this:
-3x ≤ -27
Now we'll solve for x:
Divide both sides by -3:
x ≥ 9
So, the least number of bananas your character slipped on is 9.
To find the least number of seconds of race time, we need to multiply the number of bananas by 2 seconds per banana:
9 bananas * 2 seconds/banana = 18 seconds
So, the least amount of race time your character took to slip on bananas is 18 seconds.

10x-9y=46 and -2x+3y=5 solve using elimination
Answer:
x = 15.25
y = 71/6
Step-by-step explanation:
10x -9y = 46
-2x + 3y = 5
Time the second equation by 5
10x - 9y = 46
-10x + 15y = 25
6y = 71
y = 71/6
Now put 71/6 back in for y and solve for x
10x -9(71/6) = 46
10x -106.5 = 46
10x = 152.5
x = 15.25
Let's check
-2(15.25) +3(71/6) = 5
-30.5 + 35.5 = 5
5 = 5
So, x = 15.25 and y = 71/6 is the correct answer.

How long will it take Ramon to read the entire novel if he continues to read his current rate
Based on the provided information, a. Ramon reads faster and b.it will take Ramon approximately 16.77 hours to read the entire novel if he continues to read at his current rate.
To answer this question, we need to calculate the reading rate of both Skyler and Ramon, and then compare them to see who reads faster. We also need to use Ramon's reading rate to calculate how long it will take him to read the entire novel.
a. To calculate Skyler's reading rate, we can divide the number of pages she has read by the number of hours she has spent reading:
Skyler's reading rate = 145 pages / 5 hours = 29 pages/hour
Similarly, we can calculate Ramon's reading rate:
Ramon's reading rate = 124 pages / 4 hours = 31 pages/hour
Since Ramon's reading rate is higher than Skyler's, Ramon reads faster.
b. To calculate how long it will take Ramon to read the entire novel, we can use his reading rate and the total number of pages in the novel:
Time = Total number of pages / Reading rate
Time = 520 pages / 31 pages/hour = 16.77 hours
So, it will take Ramon approximately 16.77 hours to read the entire novel if he continues to read at his current rate.
In conclusion, Ramon reads faster than Skyler, and it will take him approximately 16.77 hours to read the entire Vigo the Vampire Hunter novel at his current reading rate.
Note: The question is incomplete. The complete question probably is: The new Vigo the Vampire Hunter novel is 520 pages. Skyler has read 145 pages in 5 hours. Ramon has read 124 pages in 4 hours. a.
