or $140 for 18ft² = $140 for 324ft
or $140 ÷ 324ft = $0.43 per foot
Answer:

Step-by-step explanation:
The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.
A general form of a downward parabola is given as:

Where
is the vertex of the parabola and 'a' is a constant.
Now, let 'h' be the vertical height and 't' be the time taken.
So, the equation would be of the form:

Now, as per question:
h = 2 seconds, k = 13 feet.

Now, taking a = 1. So, the formula that can be used is:

Proof:
3 consecutive integers are x, x+1 , x+2.
Add these values.
x+x+1+x+2
3x+3
3×(x+1)
3(x+1) is the multiple of 3 for any integer value of x.
Selection 4 is appropriate.
The claim is incorrect: there are 27 cubic feet in a cubic yard.
Answer:
