Answer:
Let the age of Aman's son is x years.
So the age of Aman will be 3x years.
Ten years ago, the age of Aman's son = x - 10 and Aman's age = 3x - 10.
So according to question,
5(x - 10) = 3x - 10
or 5x - 50 = 3x - 10
Transposing 3x to the LHS and -50 to the RHS:
5x - 3x = -10 + 50 = 40
or 2x = 40
or x = 20
So Aman's age = 3x = 60 years and
Aman's son's age = x = 20 years.
Answer:
3610 dollars
Step-by-step explanation:
Remark
If you take the Cube Root of the volume, that will give you the length of an edge of the cube. If you square the edge, you get the area of one of the faces of the cube.
The Cost = the Area of 1 face * 10 dollars. is the answer.
Given
Volume = 6859 cubic feet
Cost per square foot = 10 dollars.
Solution
V = 6859 feet^3 Take the cube root of both sides
Edge = ∛V
Edge = ∛V = ∛6859
Edge = 19 feet exactly.
Area of the floor = s^2
Area of the floor = 19^2
Area of the floor = 361 square feet
Cost = 10 * 361 = $3610
