The equation that represents the volume, v, as a function of the height, h is given as: V(h) = 36πh,
where h is the height in meters and V is the volume in cubic meters.
The volume of a cylinder can be calculated using the formula V=πr²h.
Here, we have a number of cylinders with a radius of 6 meters.
Let h represent the height in meters and v represent the volume in cubic meters.
To write an equation that represents the volume, v,
as a function of the height, h,
we can substitute the value of r (radius) with 6m in the formula of the cylinder’s volume,
V = πr²h.
So we get:
V = π(6m)²h
V = 36πh

g the sequence is decreasing and bounded below by 0. explain in clear english (briefly) why this means it must have a limit.
Since the sequence is always decreasing and cannot go below the lower bound, it becomes increasingly closer to the lower bound, and thus converges to a limit.
A sequence is said to be decreasing if each term is smaller than the previous one, and bounded below if there exists a lower bound such that no term in the sequence is smaller than this bound. In this case, the sequence is decreasing and bounded below by 0.
When a sequence is both decreasing and bounded below, it must have a limit because the terms cannot continue to decrease indefinitely, as they cannot go below the lower bound (in this case, 0). This means that as we progress through the terms of the sequence, the difference between consecutive terms will decrease and eventually approach a constant value.
The limit of a sequence is a value that the terms of the sequence approach as they get closer and closer to the end. In this situation, the limit is the smallest possible value that the sequence can approach, without going below the lower bound.

Números que multiplicados me den 24 y sumados me den -11
The two numbers that multiply to give 24 and add to give -11 are -3 and -8.
How do we get these numbers?To find these numbers, you can use a system of equations. Let x and y be the two numbers. Then we have:
xy = 24 (because the two numbers multiply to give 24)x + y = -11 (because the two numbers add to give -11)We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for x:
x + y = -11
x = -11 - y
We can then substitute this expression for x into the first equation:
xy = 24
(-11 - y)y = 24
Expanding and rearranging, we get:
y^2 + 11y + 24 = 0
This is a quadratic equation that we can solve using factoring or the quadratic formula. Factoring, we get:
(y + 3)(y + 8) = 0
So either y + 3 = 0 or y + 8 = 0. This means that y can be -3 or -8. Substituting each of these values into x = -11 - y, we get:
If y is -3, then x is -11 - (-3) = -8
If y is -8, then x is -11 - (-8) = -3.

C 4 2/7 pounds
D 8 16/21 pounds
The number of pounds that he will have left over from 11 3/7 pounds is 4 2/7
How many pounds will he have left over?To find out how many bags of granola Alex can fill, we need to divide the total amount of granola he made by the amount of granola in each bag.
We can convert 11 3/7 pounds to an improper fraction:
11 3/7 pounds = 80/7 pounds
Also, we have
2 2/3 pounds = 8/3 pounds
Now we can divide the total amount of granola by the amount in each bag:
(80/7) ÷ (8/3)
To divide fractions, we invert the second fraction (change it to its reciprocal) and multiply:
(80/7) × (3/8)
Simplifying, we get:
(80 x 3) / (7 x 8) = 30/7

The total number of units produced in an 8-hour day is approximately 22.86 units.
There are different ways to approach this problem, but one possible method is to use the concept of cycle time and the total available production time to determine the number of units produced in a day.
An operation is performed on a batch of 100 units.
Setup time is 20 minutes and run time is 1 minute.
The total number of units produced in an 8-hour day is:
Step 1: Find the cycle time per unitThe cycle time per unit is the sum of the setup time and the run time:
Cycle time = setup time + run time = 20 minutes + 1 minute = 21 minutes.
Step 2: Find the total available production time in a day
One day has 24 hours, but 8 hours are not available for production due to breaks, maintenance, and other factors. Therefore, the total available production time is:
Total available production time = 8 hours × (60 minutes per hour) = 480 minutes.
Step 3: Calculate the number of units produced in a day
The number of units produced in a day is the total available production time divided by the cycle time per unit:
Units produced = total available production time ÷ cycle time= 480 minutes ÷ 21 minutes≈ 22.86 units (rounded to two decimal places)
Therefore, the total number of units produced in an 8-hour day is approximately 22.86 units.
This assumes that there is no variability in the process, and that all units are of good quality.

An angle inscribed in a semicircle is a right angle. Thus, m∠DFE = 90°
m∠EDF = 180 - 90 - 63 = 27° (sum of angles in a triangle)
m∠EDF = 1/2 * arc FE
27° = 1/2 * arc FE
arc FE = 2 * 27
arc FE = 54°
No. 7
The opposite angle in a cyclic quadrilateral add up to 180°. That is:
m∠A + m∠C = 180°
m∠A + 101 = 180
m∠A = 180 - 101
m∠A = 79°
m∠B + m∠D = 180°
m∠B + 68 = 180
m∠B = 180 - 68
m∠B = 112°

In a sale, the normal price of a boat is reduced by 15%
The sale price of the boat is £272 000
Work out the normal price of the boat.
Answer:
£320 000
Step-by-step explanation:
Let x = original price of the boat.
When you reduce a price by 15%, what percent remains in the sale price?
100% - 15% = 85%
After reducing the price of the boat by 15%, the sale price is 85% of the original price.
85% of x = £272 000
0.85x = 272 000
Divide both sides by 0.85
x = 320 000

student id numbers are created using the digits 0-9. how many five- digit student id numbers can be created if repeat digits are allowed? what if repeats are not allowed?
There are 100,000 possible five-digit student ID numbers that can be created if repeat digits are allowed (10^5).
However, if repeats are not allowed, there are only 9 x 9 x 9 x 9 x 9 = 590,490 possible student ID numbers that can be created (9^5).
The reason for the difference is that when repeats are allowed, you can use the same digit multiple times, for example "11111".
When repeats are not allowed, you can only use each digit once, for example "12345". The possible permutations of the digits 0-9 increase as more digits are added to the ID number, meaning that the more digits there are, the more possible combinations there are.
Therefore, when repeats are not allowed, the number of possible combinations is reduced significantly. In the case of five-digit student ID numbers, the difference is almost twofold.

After how many weeks do you think it would be unreasonable to continue counting
individual mosquitoes? And finally, at the end of the 13-week mosquito season, how
many mosquitoes would you expect to be in the trap? Use complete sentences to
explain both of your answers below.
(Table if needed)
Week | Mosquitos
0 | 8
1 | 12
2 | 18
3 | 27
We can expect approximately 90 mosquitoes in the trap at the end of the 13-week mosquito season.
How to determine how many mosquitoes would you expect to be in the trapBased on the given data, we can observe that the number of mosquitoes is increasing over time, and the increase is not constant. So, it would be unreasonable to continue counting individual mosquitoes after a certain point.
To estimate the number of mosquitoes at the end of the 13-week mosquito season, we can assume that the rate of increase remains constant over time. Using this assumption, we can find the average increase in mosquitoes per week, which is the difference between the number of mosquitoes in the last week and the number in the first week, divided by the number of weeks:
Average increase = (27 - 8) / 3 = 6.33
Then, we can use this average increase to estimate the number of mosquitoes in the 13th week:
Number of mosquitoes in the 13th week = 27 + 6.33 × 10 = 90.3
Since we cannot have a fraction of a mosquito, we can round this estimate to the nearest whole number.
Therefore, we can expect approximately 90 mosquitoes in the trap at the end of the 13-week mosquito season.

A pizza shop surveyed a random group of customers to determine their favorite pizza topping. Out of 400 people, how many would you expect to say their favorite topping is sausage?
The percent that reported mushroom as their favorite from the pizza shop survey would be 10 %.
The percent that instead reported cheese or pepperoni as their favorite is 62.5 %.
Out of 400 people, the number that would say their favorite was sausage is 50 people .
How to find the number of people in the survey ?The percent that prefer mushroom would be:
= Number of those who chose mushroom / Number surveyed
= 8 ( 35 + 8 + 15 + 12 + 10 )
= 8 / 80
= 10 %
The percentage that instead chose cheese or pepperoni:
= ( 15 + 35 ) / ( 35 + 8 + 15 + 12 + 10 )
= 50 / 80
= 62.5 %
The number out of 400 that would be expected to choose sausage :
= 10 / ( 35 + 8 + 15 + 12 + 10 ) x 400

What is the volume of the composite figures?
Total volume of the composite figure using volume of cuboid formula is = 120ft³.
Define volume?A cuboid's volume is a measurement of how much room it occupies. A three-dimensional shape with dimensions of length, breadth, and height is the cuboid. We can keep stacking them, starting with a rectangular sheet, until we achieve a shape with a particular length, breadth, and height.
The shape of this stack of sheets is a cuboid, which has 6 faces, 12 edges, and 8 vertices. The (unit)³ is used to represent a cuboid's volume.
In the given figure,
Length of cuboid = 6ft.
Breadth of cuboid = 3ft.
Height of cuboid = 5ft.
Length of second cuboid = 4ft.
Height of second cuboid = 5ft.
Breadth of second cuboid = 3ft.
Volume of first cuboid = length × breadth × height.
= 6 × 3 × 5
= 90ft³
Volume of second cuboid = 4 × 3 × 5
= 60ft³
Now the second cuboid is half.
So, volume becomes = 60/2
= 30ft³.
So, total volume of the figure = 90 + 30 = 120ft³.

From the top of an 18-meter lighthouse, the angle of depression to sight a boat is 4°. What is the distance between the boat and the base of the lighthouse, to the nearest tenth?
ASAP TIMED
Step-by-step explanation:
The side opposite to the 4 degree angle is 18 m
The side adjacent the 4 degree angle is x
tan(4) = opposite / adjacent
adjacent = opposite / (tan(4))
adjacent = 18 / tan(4)
adjacent = 257.41
each page number of a 488-page book is printed one time in the book. the first page is page 1 and the last page is page 488. when printing all of the page numbers, how many more 4's are printed than 8's?
the number of more 4's printed than 8's is 188 - 59 = 129.
We can approach this problem by counting the number of times the digit 4 appears and the number of times the digit 8 appears in the page numbers from 1 to 488.
First, let's count the number of times the digit 4 appears. We can break down the counting into three cases:
The digit 4 appears in the units place (page numbers 4, 14, 24, ..., 484): there are 49 such page numbers (from 4 to 484, incrementing by 10).
The digit 4 appears in the tens place (page numbers 40 to 49, 140 to 149, ..., 440 to 449): there are 50 such page numbers.
The digit 4 appears in the hundreds place (page numbers 400 to 488): there are 89 such page numbers.
Thus, the total number of times the digit 4 appears is 49 + 50 + 89 = 188.
Next, let's count the number of times the digit 8 appears. We can break down the counting into two cases:
The digit 8 appears in the tens place (page numbers 80 to 89, 180 to 189, ..., 480 to 489): there are 50 such page numbers.
The digit 8 appears in the hundreds place (page numbers 800 to 880): there are 9 such page numbers.
Thus, the total number of times the digit 8 appears is 50 + 9 = 59.
Therefore, the number of more 4's printed than 8's is 188 - 59 = 129.
