Instance variables are often called "fields" to help distinguish them from other variables you might use.
<h3>What are Instance variables?</h3>
Instance variables are defined within a class but outside of any method, constructor, or block.
Some key points related to Instance variables are-
- When heap space is allocated to an object, a slot is created for every instance variable value.
- Whenever an object is created with keyword 'new,' instance variables are created, and they are destroyed whenever the object is destroyed.
- Instance variables store values that need to be referenced by multiple methods, constructors, or blocks, as well as vital components of an entity's state which must be available throughout the class.
- Before or after use, instance variables could be declared just at class level.
- Variables, for example, can be given access modifiers.
- Only those methods, constructors, and blocks in the class have access to the instance variables.

Step-by-step explanation:
To find the slope, you need to points of a line. These points (in this case) are (0,5) and (1,27)
There is a formula to figure out slope.
That is-
Slope= y1-y2
------------
x1-x2
What the equation is saying is that you subtract both the y coordinates and then subtract both the x coordinates. Finally, you divide the y coordinates by the x coordinates.
5-27=-22
0-1=-1
-22/-1=22
The slope is 22
Answer:
Well, the tank's volume is 1.2 x 1.2 x 1.35 = 1.944 m³ = 1944 litres.
It is half-full, so it contains 1944 / 2 = 972 litres of water.
That is enough to fill 972 / 9 = 108 9-litre buckets.
Step-by-step explanation: h = height of water = 1.35 m/2 = 0.675 m
A = area of tank = s² = (1.2 m) = 1.44 m²
V = volume of water
V = Ah = (1.44 m²)(0.675 m)
