a. The water in the second tank decreases at a faster rate than the water in the first tank. The initial water level in the first tank is greater than the initial water level in the second tank.
Step-by-step explanation:
Step 1:
It is given that the time remaining in first tank is given by the equation y = -10x + 80. We can get the total water in the tank by substituting x = 0 in the equation. The total volume of water in first tank is 80 litres.
Step 2:
The value of y in the equation y = -10x + 80 will be 0 when the tank is fully empty. When y = 0 , 10x = 80, so x = 8. We can conclude that the first tank empties fully in 8 minutes.
In 8 minutes 80 litres of water is emptied from first tank. So the water in the first tank decreases at rate of 80 / 8 = 10 litres per minute
Step 3:
As per the given table for the second tank, 60 litres of water remains when x =0. So the total volume of water in the second tank = 60 litres.
Step 4:
As per the given table for the second tank, the volume becomes 0 in 5 minutes. In 5 minutes 60 litres of water is emptied from second tank. So the water in second tank decreases at rate of 60 / 5 = 12 litres per minute.
Step 5:
The initial volume of water in first tank is higher. The water in second tank decreases at a faster rate than the first tank.
Step 6:
The only correct option is:
a. The water in second tank decreases at a faster rate than the water in the first tank. The initial water level in first tank is greater than the initial water level in the second tank.

Area of Composite Shapes</h2>
To find the area of composite shapes, we can break the bigger shape down into small, simpler shapes, and find the sum of their areas.
For this triangle, we will need to know the formula to find the area of a triangle:
<h2>Solving the Question</h2>
The given shape can be seen as one large triangle with a little triangle cut out of it. To find the shaded region, we can:
- Find the area of the large triangle
- Find the area of the little triangle
- Subtract the area of the little triangle from the large triangle
<h3>Area of the Large Triangle</h3>
⇒ Plug in the values given for the base and height:
<h3>Area of the Small Triangle</h3>
⇒ Plug in the values given for the base and height:
<h3>Subtract the Area of the Small Triangle from the Area of the Large Triangle</h3>
<h2>Answer</h2>
The area of the shaded region is 
.

this is because his income increases at a constant rate. At any given week, his income increases by double
Step-by-step explanation:
An exponential function is usually in the form : 
where a = positive constant other than 1
x = variable component
for example ,
Assume that Jordan saves $15. he increases this amount by 10% weekly. this statement represents an exponential function.
The amount he would have in 7 weeks = 15 x (1.1)^7 = 29.23
