The value of d is 27/2 when v =30
<h3>What is equation?</h3>
Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal
Suppose that d is directly proportional to the square of v.
So the equation is, d ∝ v² equals to d = kv², where<em> k</em> is a constant.
So in order to find the value of <em>k</em>,
d = <em>k</em> v²
d = 6, v = 20,
Substitue the value of d and v into the equation :
6 = <em>k</em>(20)²
k = 6/400
k = 3/200
Substitue the value of <em>k</em> and v =30 into the equation,
d = 3/200(30)²
d = 2700/200
d = 27/2
Hence, the value of d is 27/2 when v =30

Elise will have enough gas to get to her sisters house and back. she will have 437 miles of gas before she goes.
Answer:
3/400
Step-by-step explanation:
Let w represent earth's water
let f represent fresh water and let g represent ground water
Therefore, fraction of earth's water,w, that is ground water = 3/400
I think it would be either 6:8,or 3:4
I don't know the answer sorry,
