Step-by-step explanation:
From the law if variation,
x <> y ______(1) ,where <> is known as the constant if proportionality.
x = k/y where k is a constant____(2)
Substitute for the values of x and y to get the k
9 = k/6
Therefore k= 54
To find the value of x, go back to equation 2 and substitute for the values if k and y given and computed.
x = 54/15; reduced to lowest term
x = 18/5
x = 3.6

$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher
From the total $79 we substract the $29 she paid with cash or card.
79-29=50
So the value of the voucher is $50

Answer: The volume of cylinder Q is 12 times the volume of Cylinder P.
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
If cylinder Q has radius, r and height, h,
Then
Volume of cylinder Q = πr²h
For cylinder P,
Height = 3h
Radius = 2r
Volume of cylinder P = π(2r)² × 3h
= 4πr²× 3h = 12πr²h
Therefore, the ratio of the volume of cylinder P to the volume of cylinder Q is
12πr²h/πr²h = 12
