Answer:
Melissa lives 1/6 of mile closer
Step-by-step explanation:
Melissa lives 5/6 of a mile from the bus stop and Pete 2/3 of a mile from the bus stop. We can determine how closer pete lives to the bus stop than melissa by subtracting the values but first we need to write them in common denominators: The common denominator is 6. Therefore we must multiple 2/3 by 2/2:
Therefore:
Melissa lives 1/6 of mile closer to the bus stop than Pete
Answer:
Side length = cm , Height =
cm , Volume =
cm³
Step-by-step explanation:
Assume
Side length of base = x
Height of box = y
total material required to construct box = A ( given in question)
So it can be written as
A = x² + 4xy
4xy = A - x²
Volume of box = Area x height
V = x² ₓ y
V = x² ₓ ( )
V =
To find max volume put V' = 0
So taking derivative equation becomes
A = 3
=
x =
put value of x in equation 1
y =
y =
y =
So the volume will be
V = × y
Put values of x and y from equation 2 & 3
V =
V =
