Answer:
Step-by-step explanation:
Rohan is a generous person who cares deeply for his maid and her two children. On Rohan's birthday, he plans to give both of them the same number of dresses. This situation can be solved using Euclid’s axiom that states “things which are equal to the same thing are also equal to one another”. Therefore, after Rohan's birthday each child will have an equal number of dresses as they were given an identical amount from him.
This kind gesture by Rohan demonstrates his commitment towards taking care of those around him and providing fairness in all situations possible - it serves as a reminder that we should always strive for equality among people regardless of their backgrounds or social statuses in life! By following this axiom, everyone can benefit from having access to resources no matter what their circumstances may be; thus creating a more equitable society overall.
The act done by Rohana is praiseworthy and must serve as an example for others too so they understand how important it is treat everyone equally regardless if they belong to different castes or classes in our society! We should take measures like these on regular basis so that true justice prevails everywhere without any discrimination whatsoever- this would make sure everybody has access basic necessities such us clothes just like Rohana provided his maid's kids with new sets on his own birthday!
Why do we calculate the mean?
Mean is calculated to get an idea of the average of the observations in the data set.
The average value of the observations in a data set is called the mean or average . It is calculated by dividing the sum of observations by the number of observations i.e.
u = (x1 + x2 + x3 + .... + xn)/n
where u is the mean , x1 , x2 ..., xn are data observations and n is the number of observations.
For example, we have values as 1,2,3,4,5 and we want to calculate the mean . Then it is calculated by
u = (1+2+3+4+5) / 5 = 3.
So, the mean is 3.
Therefore, mean is calculated to get an average or an idea of a certain number of observations.

Answer:
Step-by-step explanation:
The point-slope form of the equation of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
So, the equation for this problem, let
[tex](x_1,y_1)=(2,-1)[/tex]

a flea collar for dogs contains an active ingredient that evaporates at a rate proportional to the amount still present. half of the ingredient evaporates in the first 20 days after the collar is removed from the protective packaging. if the collar becomes ineffective after 70% of the active ingredient has evaporated, how many days does the collar remain effective?
Therefore ,the collar remain effective for 26.44 days.
Who defines order?In mathematics, there are numerous ways to use the word "order." It most frequently refers to the quantity of elements in (for example, conjugacy class order, graph order, group order, etc.) or describes the biggest term (for example, curve order, surface order, or polynomial order) that appears in a mathematical object.
Here,
=>Rate of evaporation=k=dr/dt
=> amount still present=R.
Thus ,It's a first order reaction.
So, half life=0.693/k.
20=0.693/k.
=> k=0.0346
Now,
60% of active ingredient has been evaporated.
So, 40% left.
Time taken=T=(2.303/k)log(R/0.4R)
T=(2.303/0.0346)log(5/2)
T=66.56(log5-log2)
T=66.56(0.699-0.301)
T=66.56(0.398)
T=26.44 days.

The price of a single chicken is $8 and the price of a single duck is $5.
The prices can be determined by forming the linear equation in two variables.
Given that,
Michael sold last month, 50 chickens and 30 ducks for $550.
This month, he sold 44 chickens and 36 ducks for $532.
Let the price of single chicken be 'a' and the price of a single duck be 'b'. Then the linear equation will be:
50a+30b=550 ____________(1)
44a+36b=532 ____________(2)
Solving equation (1) for the value of 'b'.
b=550-50a/30
b=55/3 - 5a/3 ____________(3)

The graph of which equation is parallel to the graph of 4x - 3 = 12?
The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.
What is the Equation of Parallel Lines?If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.
Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:
4x - 3y = -12
-3y = -4x - 12
-3y/-3 = -4x/-3 - 12/-3
y = 4/3x + 4
This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.
The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

Find its perimeter.
Answer:
Here is the answer
Step-by-step explanation:
To find the perimeter of a triangle, we need to add up the lengths of all three sides. In this case, the sides of the triangle are given by the expressions 3x2 - y2, 4x2 - 7xy + 4y, and -3x + 7xy + 8y2.
To find the perimeter, we can simply add up these three expressions:
Perimeter = 3x2 - y2 + 4x2 - 7xy + 4y - 3x + 7xy + 8y2
= 7x2 - 3xy + 12y
This is the perimeter of the triangle. Note that the perimeter is a scalar quantity, not a vector, so it does not have a direction associated with it.
