well, we know that 1ft³ = 7.48 gallons, alright, we have a volume in gallons and a diameter in feet, so if we were to use the diameter in feet to get the volume what we would end up will be a volume in ft³, so let's convert firstly the gallons to ft³ then
why do I use a fraction? for the sake of not losing value in the rounding, so let's use the fraction for the volume of a right-circular cylinder
Answer:
answer is in the picture.
Answer:
The growth rate per year is 20,988.
The population of the city in 2005 is 269,940.
Step-by-step explanation:
The first sentence is not true in general. Consider the equation
. There are no solutions. Now consider
. There is only one solution,
.
But whatever. You're asked to demonstrate that
has two solutions (which is true; the right hand side must be a positive integer in order to have two solutions). This follows immediately from the definition of absolute value, which says
So suppose
. Then
Now suppose
. Then
So two solutions to
are
.
Answer:
Side length = 8xy^2
Perimeter = 32xy^2.
Step-by-step explanation:
As it's a square the side length is the square root of the area
= √ (64x^2y^4)
= 8xy^2.
The perimeter is 4 times this.
