We know that
if <span>y is inversely proportional to x
then
y=k/x
where k is the constant of variation
so
for x=0.5 y=12
find the value of k
12=k/0.5-----> k=12*.5----> k=6
y=6/x
the rule is the following
y=6/x

Answer:
The correct answer is 720.
Step-by-step explanation:
There are 10 different styles of toilet paper available in the house.
We need to choose 3 types from these 10 styles.
Therefore number of ways we can select these 3 types are given by
ways = 120 possible ways.
Now we need to put these toilet paper in each of the 3 bathrooms. So we have possible 3! = 6 possible ways.
Therefore the number of ways one would select 3 toilet paper and then placing each of the bathrooms in the house is given by 120 × 6 possible ways = 720 ways.
