A man gave 5/12 of his money to his son , 3/7 of the remainder to his daughter and the remaining to his wife if his wife gets rs 8700 what is the total amount
The total amount the man had = 52,200 rupees. Out of this, he gave 21,750 rupees to his son, 13,050 rupees to his daughter, and 17,400 rupees to his wife , the total amount given away by the man = 21,750 + 13,050 + 17,400 = 52,200 rupees.
A man gave 5/12 of his money to his son, 3/7 of the remainder to his daughter, and the remaining to his wife. If his wife gets Rs. 8,700, what is the total amount?
The given problem can be solved using the concept of ratios and fractions. Let us solve the problem step-by-step.Assume the man had x rupees with him.The man gave 5/12 of his money to his son.
The remaining amount left with the man = x - 5x/12= (12x/12) - (5x/12) = (7x/12)The man gave 3/7 of the remainder to his daughter.'
Amount left with the man after giving it to his son = (7x/12)The amount given to the daughter = (3/7) x (7x/12)= (3x/4)The remaining amount left with the man = (7x/12) - (3x/4)= (7x/12) - (9x/12) = - (2x/12) = - (x/6) (As the man has given more money than what he had with him).
Therefore, the daughter's amount is (3x/4) and the remaining amount left with the man is (x/6).The man gave all the remaining amount to his wife.
Therefore, the amount given to the wife is (x/6) = 8700Let us find the value of x.x/6 = 8700 x = 6 x 8700 = 52,200
Therefore, the man had 52,200 rupees with him.He gave 5/12 of his money to his son. Therefore, the amount given to his son is (5/12) x 52,200 = 21,750 rupees.
The remaining amount left with the man = (7/12) x 52,200 = 30,450 rupees.He gave 3/7 of the remainder to his daughter. Therefore, the amount given to his daughter is (3/7) x 30,450 = 13,050 rupees.
The amount left with the man = (4/7) x 30,450 = 17,400 rupees.The man gave 17,400 rupees to his wife.

Answer: any negative value
Step-by-step explanation:
g(x)= ax², inc on x<0 & dec on x>0
Firstly we need to get the derivative of g(x)
g'(x)=2ax
for inc interval g'(x) should be +ve
x<0 (i.e. x= -ve), then a must be -ve
for dec interval g'(x) should be +ve
x>0 (i.e. x= +ve), then a must be -ve
so in both cases a must be a negative constant

https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.
So we have shown that each family paid **Rs 13,522** for the trip

x° + 126° = 180° and value of x is 54°
Step-by-step explanation:
Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.
We know that, in a triangle the sum of all angles Is 180°.
If two sides are equal then also two angles are also equal of that sides.
Now,
63° + 63° + x° = 180°
x° + 126° = 180°
Now, To find the value of x
x° + 126° = 180°
x° = 180° - 126°
x = 54°
Thus, The value of x is 54°
FOR VERIFICATION ONLY:-x° + 126° = 180°
54° + 126° = 180°
180° = 180°

Answer:
\(\angle B_{1} \approx 31.668^{\circ}\), \(\angle B_{2} \approx 148.332^{\circ}\)
\(\angle C_{1} \approx 127.332^{\circ}\), \(\angle C_{2} \approx 10.668^{\circ}\)
\(c_{1} \approx 157.532\), \(c_{2}\approx 36.676\)
Step-by-step explanation:
The Law of Sines states that:
\(\frac{a}{\sin A} = \frac{b}{\sin B}=\frac{c}{\sin C}\)
Where:
\(a\), \(b\), \(c\) - Side lengths, dimensionless.
\(A\), \(B\), \(C\) - Angles opposite to respective sides, dimensionless.
Given that \(a = 71\), \(b = 104\), \(\angle A = 21^{\circ}\), the sine of angle B is:
\(\sin B = \frac{b}{a}\cdot \sin A\)
\(\sin B = \frac{104}{71}\cdot \sin 21^{\circ}\)
\(\sin B = 0.525\)
Sine is positive between 0º and 180º, so there are two possible solutions:
\(\angle B_{1} \approx 31.668^{\circ}\)
\(\angle B_{2} \approx 148.332^{\circ}\)
The remaining angle is obtained from the principle that sum of internal triangles equals to 180 degrees: (\(\angle A = 21^{\circ}\), \(\angle B_{1} \approx 31.668^{\circ}\), \(\angle B_{2} \approx 148.332^{\circ}\))
\(\angle C_{1} = 180^{\circ}-\angle A - \angle B_{1}\)
\(\angle C_{1} = 180^{\circ}-21^{\circ}-31.668^{\circ}\)
\(\angle C_{1} \approx 127.332^{\circ}\)
\(\angle C_{2} = 180^{\circ}-\angle A - \angle B_{2}\)
\(\angle C_{2} = 180^{\circ}-21^{\circ}-148.332^{\circ}\)
\(\angle C_{2} \approx 10.668^{\circ}\)
Lastly, the remaining side of the triangle is found by means of the Law of Sine: (\(a = 71\), \(\angle A = 21^{\circ}\), \(\angle C_{1} \approx 127.332^{\circ}\), \(\angle C_{2} \approx 10.668^{\circ}\))
\(c_{1} = a\cdot \left(\frac{\sin C_{1}}{\sin A} \right)\)
\(c_{1} = 71\cdot \left(\frac{\sin 127.332^{\circ}}{\sin 21^{\circ}} \right)\)
\(c_{1} \approx 157.532\)
\(c_{2} = a\cdot \left(\frac{\sin C_{2}}{\sin A} \right)\)
\(c_{2}= 71\cdot \left(\frac{\sin 10.668^{\circ}}{\sin 21^{\circ}} \right)\)
\(c_{2}\approx 36.676\)
The answer are presented below:
\(\angle B_{1} \approx 31.668^{\circ}\), \(\angle B_{2} \approx 148.332^{\circ}\)
\(\angle C_{1} \approx 127.332^{\circ}\), \(\angle C_{2} \approx 10.668^{\circ}\)
\(c_{1} \approx 157.532\), \(c_{2}\approx 36.676\)

–2.5p – 20 = 9p + 37.5
Answer:
p = - 5
Step-by-step explanation:
–2.5p – 20 = 9p + 37.5
combine like terms:
- 2.5p - 9p = 37.5 + 20
simplify:
- 11.5p = 57.5
p = 57.5 / -11.5
p = - 5
Answer:
The answer is p = -5
Step-by-step explanation:
-2.5p - 20 = 9p + 37.5
(move constants to one side by adding 20 to both sides)
-2.5p = 9p + 57.5
(move all terms with the "p" variable to one side by subtracting 9 from both sides)
-11.5p = 57.5
(divide both sides by -11.5 to isolate the variable)

By using graphical method, find optimal solution of the problem max z = 3x + y s.t 2x - y ≤ 5 -x + 3y ≤ 6 x ≥ 0, y ≥ 0
By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.
To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.
Let's start by graphing the constraints:
1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.
2. Plot the line -x + 3y = 6 using a similar process.
3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.
Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.
Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.
Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

The probability of 3 or more deaf people in a sample of 100 is given as follows:
0.3633 = 36.33%.
What is the binomial distribution formula?The mass probability formula, giving the probability of x successes, is of:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.The values of the parameters for this problem are given as follows:
p = 0.02, n = 100.
The probability of 3 or more deaf people are given as follows:
P(X >= 3) = 1 - P(X < 3).
In which:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).
Hence:
P(X = 0) = 0.98^100 = 0.1326.P(X = 1) = 100 x 0.02 x 0.98^99 = 0.2707.P(X = 2) = 99 x 50 x 0.02² x 0.98^98 = 0.2334.Thus:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
P(X < 3) = 0.1326 + 0.2707 + 0.2334
P(X < 3) = 0.6367.
P(X >= 3) = 1 - P(X < 3).
P(X >= 3) = 1 - 0.6367.
P(X >= 3) = 0.3633.

Answer:
1057
Step-by-step explanation:
tower is 60 feet high.
angle of 3.25 degrees.
3.25/360 * 2 * pi * r = the arc length of this angle.
that would be equal to 0.0567232007* r
if we assume the arc length and the height of the tower are approximately equal, then 0.0567232007 * r = 60
solving for r, we get r = 60/0.0567232007 = 1057.768237 feet.
that's about how far the tower is from the observer.
since the arc length is going to be a little longer than the length of the chord formed by the flagpole, this means that the distance of 1057.768237 meters is going to be a little less than the actual distance.

By applying the concept of corresponding angles in similar triangles, we were able to establish the value of x as 25 in the given scenario.
In the given problem, we are provided with information about the angles in two similar triangles: triangle ABC and triangle STU. It is stated that angle UTS in triangle STU is 100 degrees, and since corresponding angles of similar triangles are congruent, we can conclude that angle STU is also 100 degrees.
Next, we examine angle BAC in triangle ABC, which is given as 4x. Using the same logic, we know that angle BAC is also congruent to angle STU. Therefore, we can equate the two angles:
angle BAC = angle STU
4x = 100
To find the value of x, we divide both sides of the equation by 4:
x = 100/4
x = 25
Hence, we determine that x is equal to 25. This method allows us to leverage the known information about one triangle to infer the measurements of corresponding angles in the other similar triangle.
