Answer:
It is given that the volume of a cone = cubic units
Volume of cone with radius 'r' and height 'h' =
Equating the given volumes, we get
=
It is given that the height is 'x' units.
Therefore,
Therefore, r = 3x
So, the expression '3x' represents the radius of the cone's base in units.
Answer:
Fred would take 33 days to save $ 70.95.
Step-by-step explanation:
The number of days () is directly proportional to the quantity of money saved (
), in monetary units, then we can calculate the time taken to save $ 70.95 by simple rule of three:
Fred would take 33 days to save $ 70.95.
The solution of the equation is
Step-by-step explanation:
To simplify an equation of x
∵ The equation is
- Multiply all terms of the equation by 4 to cancel the denominator
of the 2nd term in the left hand side
∵ The equation is
∴ 8x + (1 - x) = 12
∴ 8x + 1 - x = 12
- Add like terms
∴ (8x - x) + 1 = 12
∴ 7x + 1 = 12
- Subtract 1 from both sides
∴ 7x = 11
- Divide both sides by 7
∴
The solution of the equation is
