A person died leaving behind inheritance of Rs. 300000. Distribute the amount among 4 sons and 3 daughters so that each son gets double of what a daughter gets. Find the share of each when a debt of Rs. 80,000 was also to be paid.
The inheritance problem deals with distributing Rs. 300,000 among 4 sons and 3 daughters after a Rs. 80,000 debt is paid. Using algebra and ratios, it is determined that each daughter receives Rs. 20,000 while each son receives Rs. 40,000.
The situation given is that a person dies leaving behind an inheritance of Rs. 300,000, which must be divided among 4 sons and 3 daughters such that each son receives double what each daughter gets. Additionally, a debt of Rs. 80,000 is to be taken out of the inheritance before distribution.
First, we need to consider the debt. Subtracting the debt from the total inheritance, we have:
Total inheritance after debt = Rs. 300,000 - Rs. 80,000 = Rs. 220,000
Now, let's assume each daughter gets x amount. Therefore, each son gets 2x the amount. We can set up the equation accounting for all sons and daughters:
3x (daughters' shares) + 4(2x) (sons' shares) = Rs. 220,000
Simplifying:
3x + 8x = Rs. 220,000
11x = Rs. 220,000
x = Rs. 20,000 (share of each daughter)
Consequently, the share of each son will be double that of a daughter, which is:
2x = 2(Rs. 20,000) = Rs. 40,000 (share of each son)

9x + 4y = 36
6x + 2.5y = 24
After multiplying by the given coefficients and adding, the new equation obtained is:
8y - 7.5y = 0
after doing the calculations the answer is:
y = 0
x = 4
Because the two equations formed were independent, they had one solution

Find the value of each variable for the right triangles. Make sure all answers are in reduced radical form. Show your work.
Answer:
i) t = 5
ii) a = 3√7
iii) x =3√13
Step-by-step explanation:
We have right triangles.
Know the two sides of the triangle and need to find the third missing side.
In order to find the third side of the right triangle, we use pythagoras theorem.
It is,
(Hypotenuse)² = (base)² + (height)²
i)
13² = 12² + t²
169 = 144 + t²
t² = 25
t = 5.
ii)
12² = 9² + a²
144 = 81 + a²
144 - 81 = a²
a² = 63
a = √63
iii)
x² = 9² + 6²
x² = 81 + 36
x² = 117
x = √117
x = 3√13

The value of a $225,000 house increases at a rate of 3.5% each year. Use a graph to predict the value of the house in 8 years.
A) ≈ $276,582
B) ≈ $286,263
C) ≈ $306,652
D) ≈ $296,282
The value of the house in 8 years. (D) ≈ $296,282
How to predict the value?The given parameters are:
Initial value, a = $225,000
Rate, r = 3.5%
The scenario is an illustration of an exponential growth function.
So, we have:
V(x) = a * (1 + r)^x
Substitute known values
V(x) = 225000 * (1 + 3.5%)^x
This gives
V(x) = 225000 * (1.035)^x
Next, we plot the graph of V(x)
See attachment
From the attached graph
V(x) = $296,282

jill traveled to the ferry office and back. the trip there took 5 hours and the trip back took 4 hours. she averaged 65 mph on the return trip. find the average speed of the trip there
We know from physics class that the formula for distance of a linear motion is given as:
d = v t
Where,
d = distance travelled
v = average velocity
t = time it took to reach the destination
Since the distance going to the office and back is just similar, therefore we can simply equate the two:
v1 t1 = v2 t2
Where 1 signifies going to the office and 2 signifies going back from the office. Therefore this yields to:
v1 * 5 hours = 65 mph * 4 hours
v1 = 52 mph
Answer: The average speed going to the office is 52 mph.
The average speed of Jill's trip to the ferry office was 52 mph, calculated by dividing the distance of 260 miles by the time of 5 hours.
To find the average speed of the trip there, we need to know the distance Jill traveled to the ferry office. Since she averaged 65 mph on the return trip which took 4 hours, the distance is calculated as speed x time, which equals 260 miles (65 mph x 4 hours).
The distance to the ferry office is the same as the distance back, so Jill also traveled 260 miles on the trip there. Given that the trip there took 5 hours, we can find the average speed by dividing the distance by the time. The average speed is 260 miles / 5 hours, which equals 52 mph.

What is the graph of the function f(x) = the quantity of x squared plus 3 x plus 5, all over x plus 2
Answer:
Your answer is in the picture below
The graph approaches x=−2 asymptotically, has no x-intercepts, and the y-intercept of the graph is the point (0, 5).
Attached graph.
The graph of the function f(x) = (x² + 3x + 5 )/(x+ 2) is a parabola that is shifted to the left by 2 units.
The parabola is similar to the graph of the function y = x², but it is narrower because the denominator of the fraction is x + 2.
The graph also has a hole at the point (-2, 5), which is the point where the denominator of the fraction is 0.

Find the greatest common factor for the group of numbers. 12 , 28 , 24
Final answer:
The greatest common factor (GCF) of the numbers 12, 28, and 24 is found by identifying the smallest powers of their common prime factors, which are 2 and 3. Multiplying these together, 2 squared times 3, gives us the GCF of 12.
Explanation:
To find the greatest common factor (GCF) of the numbers 12, 28, and 24, we break each number down into its prime factors:
28 = 2 x 2 x 7
The smallest power of 3 that is common is just 3.
Therefore, the GCF of 12, 28 and 24 is 22 x 3 = 4 x 3 = 12.
