Yep! 2/4, also known as 1/2 is larger than 2/5. You can verify this by getting a common denominator of 20 by multiplying the top and bottom of 2/4 by 5 and the top and bottom of 2/5 by 4, and asking yourself of this is true: Does 10/20=8/20? No it does not! Therefore 2/4 is bigger than 2/5!
<span>The
graph of y against x in inverse proportion is a rectangular hyperbola
but I don't see at all how this knowledge/observation is any help in
solving the problem.
Inverse proportion means that as x doubles y will halve and the equation
is xy = k where k is some number. A good example of inverse proportion
is speed and time taken over some fixed distance. In this case x could
represent the speed (mph) and y the time (h) and then k is the distance
in miles.
Since we know y=3 when x=2 we have xy = 6. Now it's easy to see when x=6 y=1.</span>
The first table is proportional. Y is 4 times X. The second table is 1.25 times X
Answer:
Volume of the tank = 636 ft³
Step-by-step explanation:
Formula for the volume of a cylinder is,
V = πr²h
Where r = radius of the cylinder
h = height of the cylinder
By substituting the values of radius and height of the water tank given in the question,
V =
= 202.5π
= 202.5 × (3.14)
= 635.85 ft³
≈ 636 ft³
Therefore, volume of the cylindrical water tank is 636 ft³.
