A grain silo has a cylindrical shape. Its diameter is 17 , and its height is 38. What is the volume of the silo?

The mean of this data set is 65.

The average distance between each data item and the mean is known as the mean absolute deviation.

The gap between each data value and the mean in absolute terms is represented by this average.

Let the mean be 'x' and the standard deviation be 'y'

3 standard deviations the mean means that we are taking away 3 standard deviations from the mean

Mathematically, we have that as;

x - 3y = 41...(i)

73 is 1 standard deviation above the mean

Mathematically;

x + y = 73...(ii)

So let us solve both equations simultaneously

Simply multiply equation (ii) by 3 then add to (i)

x - 3y = 41

3x + 3y =219

4x = 41 + 219

4x = 260

x = 260/4

x = 65.

Klaus wil be behind where he started with a distance of 8miles

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Distance can also be defined as the space or gap between two points.

Velocity = distance/time

distance = velocity × time

time = 60minutes = 1hr

therefore the distance made by Klaus in 60 minutes =

= 8 ×1

= 8miles

therefore within 60 minutes Klaus will cover a distance of 8miles from where he started.

It should be noted that the relationship between the balance and the number of withdrawals is linear, because there is a constant amount of $10 per withdrawal.

To confirm this, we can calculate the differences in balance for each pair of withdrawals:

Between withdrawals 3 and 2: 170 - 140 = 30

Based on the information, the starting amount is $200.

The equation to illustrate the withdrawal will be:

= 200 - 10w

where w = withdrawal.

These differences are constant, which means the rate of change of the balance is constant too.

By using unitary methods, the amount of rope is needed for both sites is 350 meters.

Unitary method is a mathematical problem-solving technique that involves finding the value of one unit and using it to calculate the value of other units.

Let's start by looking at Site A, which is a rectangular area with a length of 60 meters and a width of 40 meters. To surround this area with rope, we need to measure the perimeter, which is the distance around the site.

=> Perimeter = 2 (length + width)

=>  2(60 + 40)

=> 2 x 100

=> 200 meters

Therefore, we need 200 meters of rope to surround Site A.

Now let's move on to Site B, which is also rectangular but has a length of 45 meters. To find the width of Site B, we can use the fact that it is similar in shape to Site A. Similar shapes have the same angles and proportional sides, so we can use a unitary method to find the missing dimension.

The length ratio of Site B to Site A is

=> 45/60 = 3/4

Since the shapes are similar, the width of Site B must also be 3/4 of the width of Site A.

Width of Site B = 3/4 x 40 = 30 meters

Now we can use the same formula as before to find the perimeter of Site B:

Perimeter = 2 (length + width)

=> 2(45 + 30)

=> 2 x 75

=> 150 meters

Therefore, we need 150 meters of rope to surround Site B.

To find the total amount of rope needed for both sites, we simply add the two perimeters:

Total rope needed = 200 + 150 = 350 meters

Final Answer:

There are 0.036 decimeters in 3.6 millimeters.

Explanation:
To convert from millimeters to decimeters, we can use the following measurement conversion:

1 millimeter = 0.01 decimeters

So, to find out how many decimeters are in 3.6 millimeters, we can multiply 3.6 by 0.01:

3.6 * 0.01 = 0.036

Therefore, there are 0.036 decimeters in 3.6 millimeters.

The money needs to be in the account for 5 years on simple interest at the rate 5% to earn R500.

The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.

Let us suppose the time period as x.

The simple interest is given as:

SI = PRT/100

Where,

SI = Simple Interest = 500

P = Principal = 2000

R = Rate = 5%

T = x

Substituting the values:

500 = (2000)(5)(x) / 100

500 = 100x

x = 5 years

Hence, the money needs to be in the account for 5 years on simple interest at the rate 5% to earn R500.

Answer:

Gavin made a Profit of $66.69 that is 93% Profit

Step-by-step explanation:

First, we calculate the Selling Price of Jeans after converting from GBP to USD on the given rate:

Rate: £1 = $1.34

Quantity: 3

Price in USD = Selling Price per pair * Rate in USD

£34.50 * 1.34 = $46.23 per pair of jeans.

Total Selling Price = Price Per Pair * Quantity
= 46.23 * 3
= $138.69

Total Profit = Total Selling Price - Total Cost Price
= $138.69-$72
= $66.69

Percentage of Profit = Total Profit / Total Cost Price
=66.69 / 72
=92.65

Therefore, the Profit Percentage is 92.65 % the nearest whole number would be 93%

To calculate Gavin's percentage profit, find the difference between the selling price and the buying price, and calculate the percentage of the buying price that the profit represents.

To calculate Gavin's percentage profit, we need to find the difference between the selling price and the buying price, and then calculate the percentage of the buying price that the profit represents.

A number is divisible by 15 if and only if it is divisible by both 3 and 5.For a number of the form x15y to be divisible by 5, y must be either 0 or 5.

For a number of the form x15y to be divisible by 3, the sum of its digits must be divisible by 3. Since the sum of the digits is x + 1 + 5 + y = x + y + 6, x + y must be either 0, 3, 6, 9, 12, or 15.

So, we need to find all possible values of x and y such that x + y is one of these six values, and y is either 0 or 5.

If y = 0, then x must be one of the numbers 0, 3, 6, 9, 12, 15, 18, or 21, for a total of 8 possibilities.

If y = 5, then x must be one of the numbers 2, 5, 8, 11, 14, 17, or 20, for a total of 7 possibilities.

If p and q vary inversely and p = 14 when a = 4, then the work is  q = 8, p = 7.

What is inverse proportionality?

Inverse proportionality occurs when x increases and y decreases, and when x decreases and y increases.

If p and q vary inversely, this means that their product is constant:

p * q = k

where k is a constant. We can use this relationship to solve the problem.

We are given that when a = 4, p = 14. This means that:

p * a = k

14 * 4 = k

56 = k

So we know that the product of p and a is 56.

To find p when q = 8, we can use the fact that p and q vary inversely. This means that:

p * q = k

We know that k = 56, so we can substitute:

p * q = 56

We are given that q = 8, so we can substitute this as well:

p * 8 = 56

Solving for p, we get:

p = 56 / 8 = 7

Therefore, when q = 8, p = 7.

What is similar triangles ?

Similar triangles are useful in geometry and other fields because they allow us to solve problems involving unknown distances or heights. We can use the known lengths and angles of one triangle to find the lengths and angles of the other triangle, as long as we know that the two triangles are similar. This can be done using the properties of proportional relationships and the rules of similar figures.

Let's use similar triangles to solve this problem. The height of the building and the height of the flagpole are proportional to the lengths of their shadows. We can set up the following equation:

height of building / length of building's shadow = height of flagpole / length of flagpole's shadow

Let x be the height of the building. Then we have:

x / 103 = 32 / 34.5

Simplifying this equation, we get:

x = 103 * (32 / 34.5) ≈ 95.23
