Answer:
4pi in^2
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
π = pi
r = radius
h = height
Let me illustrate with an example
A cylinder has the following dimensions
r = radius = 20
h = height = 10
lateral area = 2 x π x 20 x 10 = 400π
If dimensions are reduced to one-fifth their original length, new dimensions are
r = radius = 20 x 1/5 = 4
h = height = 10 x 1/5 = 2
New lateral area = 2 x 4 x 2 x π = 16π
change in lateral area = 400π / 16π = 25
If dimensions are reduced by 1/5, lateral area would reduce by 25
100 pi / 25 = 4
Answer:
The false statement is "it can be used for one variables at a time"
Step-by-step explanation:
Given:
Simulation for NPV.
To Find :
Which statements is not correct .
Solution;
In simulation NPVs, Net present values.
<em>In Excel the simulation called as monte carlo simulation</em>
So it consists of variables like mean ,standard deviation, variance etc.
In simulation it develops the graphs .
It consists of formula for probability calculation
So it has probability distribution function.
Ultimately, It will develop the output values for input variables.
Hence The false statement will be that" it can only be used for one variable at a time"
£45 600 is more than £43 000 and less than £150 000. According to the third • point, the tax will be 40%.
Also, according to the first • point, the first £11 000 will not be taxed. So, only £34 600 will actually be taxed.
To finally get the answer, Multiply £ 34 600 by the rate of 40%, and the result is £ 13 840.
Answer:
First city: $5,500
Second city: $5,000
Step-by-step explanation:
Let's define x as the hotel price in the first city and y the hotel price in the second city. We can start with this equation:
y = x - 500 (The hotel before tax in the 2nd city was $500 lower than in the 1st.)
Then we can say
0.065x + 0.045y = 582.50 (the sum of the tax amounts were $582.50)
We place the value of y from the first equation in the second equation:
0.065x + 0.045 (x - 500) = 582.50
0.065x + 0.045x - 22.50 = 582.50 (simplifying and adding 22.5 on each side)...
0.11x = 605
x = 5,500
The cost of the first hotel was $5,500
Thus, the cost of the second hotel was $5,000 (x - 500)
Answer:
-3/4, -1/2, -2/5
Step-by-step explanation:
-1/2 = -0.5 = -10/20
-3/4 = -0.75 = -15/20
-2/5 = -0.4 = -8/20
