Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = 
52.5 * 2 = base × 7
105 = base × 7
base = 15
Here is your answer zero will always equal zero.
Answer:
Light, Volume
Step-by-step explanation:
The volume of sound; the loudness or softness of a musical passage.
Maria isn't correct of this. Adding these will get you 82960 (You add the numbers) She must have miscalculated.
If x represents the length of the box, then 42-x will be the girth. Since the largest area for a given girth is that of a square, the side length of the square cross section is (42 -x)/4.
The volume as a function of package length is then
.. v(x) = x((42-x)/4)^2
This has a maximum at x=14. The corresponding volume is 686 in^3.
