Something x -2xsomething+3
<h3>The area of base is 0.25 square meter</h3>
<em><u>Solution:</u></em>
Given that,
The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m
To find: area of base
<em><u>The volume of cylinder is given as:</u></em>

The area of base of cylinder is area of circle

Therefore,

From given,
h = 10 m
v = 2.5 kl
1 kilo liter = 1 cubic meter
Therefore,
2.5 kl = 2.5 cubic meter
Substitute height = 10 and volume = 2.5

Thus area of base is 0.25 square meter

Question 9
<u>From the previous question we know that:</u>
- The rate of draining = 2/3 gal/min
- Remaining water = 5 gal
<u>Time to empty the tank is:</u>
- 5 : 2/3 =
- 5 * 3/2 =
- 15/2 =
- 7 1/2 minutes
Answer:
tan Z = 3/4
Step-by-step explanation:

ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2
