If y varies inversely as x and y=3 when x=14, find x when y=6

1 answer:

3 0

X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.

So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.

Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)

That makes 14/6=X/3. When we cross multiply, we find that x=7.

Cylinder A has a radius of 1 m and a height of 4 m. Cylinder B has a radius of 2 m and a height of 4 m. What is the ratio of the

Svetlanka [38]

Note: The volume of a cylinder is:

radius² × π × height

First lets work out the volume of Cylinder A:

Volume = 1² × π × 4

= 4π m³

Now lets work out the volume of Cylinder B

Volume = 2² × π × 4

= 16π m³

__________________________________________

Now lets compare the volumes ( Cylinder A : Cylinder B) :

4π : 16π

Lets simplify this by dividing both sides by 4π:

4π : 16π <em>( </em>÷ <em>4π)</em>

----> 1 : 4

Answer:

Option b) 1 : 4
