We can use the DuPont model to calculate the ROE (Return on Equity):
ROE = Profit margin * Total assets turnover * Equity multiplier
Substituting the given values, we get:
ROE = 0.085 * 1.5 * 1.8 = 0.2295 or 22.95%
Therefore, Precision Aviation's ROE was 22.95%.
Rajan baut a book for Rs 180 and sold it to sajan at a profit of 20%. Sajan sold that book to nirajan at a lost 20%. At what price nirajan should sell the book to receive 5% profit ?
Solution,
CP for rajan=180 rs
Sp for rajan=(20%+1)×180
=216
Cp for niranjan=216
And, Sp=.8×216
=172.8
Cp for niranjan=172.8
For 5% profit,
Sp for Niranjan=(5%+1)×172.8
=181.44
Hence, for Niranjan to gain 5% profit, he must sell it for 181.44 rs
Answer - 181.44
Explanation - For Rajan,
Cost Price = Rs 180
Profit Percent = 20%
Profit Percent = (S.P - C.P/C.P)*100
20 = (S.P - 180/180) *100
S.P = Rs 216
For Sajan,
C.P = Rs 216
Loss Percent= 20%
Loss = (C.P - S.P/C.P)*100
20 = (216-S.P/216)*100
S.P = Rs 172.8
For Niranjan to Sell Book and get 5% profit,
C.P = Rs 172.8
Profit Percent = (S.P - C.P/C.P)*100
5 = (S.P-172.8/172.8)*100
S.P = 181.44
I need to find the maximum revenue!
The revenue is maximized for a value p = 100, and the maximum revenue is:
R = 23,500
How to maximize the revenue?We know that the number of items sold for a prize p is:
-2.35p + 470
Then the revenue will be:
R = (-2.35p + 470)*p
So we need to find the value of p that maximizes that quadratic equation, we can see that the maximum will be at the vertex, then let's write:
R = -2.35p² + 470p
The vertex is at:
p = -470/(2*2.35)
p = 100
Finally, the maximum revenue is:
R = -2.35*100² + 470*100
R = 23,500

What is a polygon?A polygon is a two-dimensional geometric shape that is defined as a closed figure with straight sides. It is made up of line segments that connect at endpoints called vertices. The term polygon comes from the Greek words "poly" meaning many and "gonia" meaning angle, indicating that polygons have many angles.
Polygons can have different numbers of sides, with the most basic being a triangle, which has three sides and three angles. Other examples of polygons include squares, rectangles, pentagons, hexagons, and octagons. The sides of a polygon do not have to be equal in length or the angles between them do not have to be the same, but they must be straight lines and the polygon must be closed.

After answering the presented question, we can conclude that As an expression result, there are 24 4-letter code symbols that may be constructed without duplication using the letters P, D, Q, and X.
what is expression ?
An expression in mathematics is a collection of representations, digits, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a combination of the two can be used as an expression. Mathematical operators include addition, subtraction, rapid spread, division, and exponentiation. Expressions are often used in arithmetic, mathematics, and form. They are employed in the representation of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.
We may use the method for permutations of n items taken r at a time to compute the number of 4-letter code symbols that can be created with the letters P, D, Q, X without repetition:
n! / (n-r)! P(n,r) = n!
where n denotes the number of items (in this example, four letters) and r the number of things taken at once (in this case, 4).
Thus far, we have:
P(4,4) = 4! / (4-4)! = 4! / 0! = 4 x 3 x 2 x 1 / 1 = 24
Hence, As a result, there are 24 4-letter code symbols that may be constructed without duplication using the letters P, D, Q, and X.

Can d holds 1/6 of the amount can b holds.
Can b holds 1/5 of the amount can a holds.
How to explain the fractionCan d holds 1/2 of the amount can c holds. This is because can d holds 3 litres and can c holds 6 litres, so if you divide the volume of can d (3 litres) by the volume of can c (6 litres), you get 3/6 or 1/2.
Can c holds 1/5 of the amount can a holds. Can c holds 6 litres and can a holds 30 litres, so if you divide the volume of can c (6 litres) by the volume of can a (30 litres), you get 6/30 or 1/5.
Can d holds 1/6 of the amount can b holds: This is because can d holds 3 litres and can b holds 18 litres, so if you divide the volume of can d (3 litres) by the volume of can b (18 litres), you get 3/18 or 1/6.
Can b holds 1/5 of the amount can a holds: This is because can b holds 18 litres and can a holds 30 litres, so if you divide the volume of can b (18 litres) by the volume of can a (30 litres), you get 18/30 which can be simplified as 3/5 or 1/5.

Find the value of z such that 0.6318 of the area lies between −z and z. Round your answer to two decimal places.
A standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.
Describe Standard Normal Distribution?The standard normal distribution is useful because it allows us to calculate probabilities for any normal distribution by converting the distribution to a standard normal distribution using a process called standardization. Standardization involves subtracting the mean of the distribution from each observation and then dividing by the standard deviation. The resulting values are called z-scores, and they represent the number of standard deviations that an observation is from the mean of the distribution.
Assuming a standard normal distribution, we know that 0.5 of the area lies between -z and z, since the normal distribution is symmetric around the mean. Therefore, we need to find the value of z such that the area between -z and z is 0.6318 - 0.5 = 0.1318.
Using a standard normal distribution table or a calculator, we can find that the area between the mean and z is 0.5 + 0.1318/2 = 0.5659. Therefore, the z-score that corresponds to this area is approximately 0.18.
Since the distribution is symmetric, the area between -z and z is twice the area between the mean and z, so we can solve for z:
0.1318/2 = 0.0659 of the area lies between the mean and z
Using a standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.
Therefore, z = 0.42 rounded to two decimal places.

The height after t seconds of a projectile that is launched upward with a velocity of 64 feet per second from the top of a 45 foot building is given by. When will the projectile attain a height of 85 feet?
The projectile will attain a height of 85 feet at approximately 0.775 seconds or 3.225 seconds.
Calculating the Time to reach a certain heightGiven that
Velocity = 64 feet per second --- v
Initial height = 45 feet --- h
The height function can be represented as
h(t) = -16t² + vt + h
So, we have
h(t) = -16t² + 64t + 45
where h is the height in feet and t is the time in seconds.
To find when the projectile will attain a height of 85 feet, we need to solve the equation for t
So, we have
-16t² + 64t + 45 = 85
-16t² + 64t - 40 = 0
Using a graphing tool, we have
t = 0.775 and t = 3.225
Therefore, the projectile will attain a height of 85 feet at approximately t = 0.775 seconds or t = 3.225 seconds.

What are Heights and Distances in trigonometry?The ideas of angles, right triangles, and the trigonometric functions of sine, cosine, and tangent are used in trigonometry to calculate heights and distances.
It is possible to determine the height of an object or the distance between two objects by measuring the angle of elevation or depression between the observer's line of sight and the object being observed and the distance between them. These ideas are frequently applied in the engineering, navigation, and surveying industries.
14. In a right-angled triangle, if one angle is 45 degrees, then the other acute angle is also 45 degrees and hence,
