This should be relatively easy, since most of us have learned and used the formula for the volume of a sphere: V = (4/3)* pi* r^3.
Just combine (4/3)pi into a single value, k, which results in V = kr^3.
Answer: a)
b) 30
Step-by-step explanation:
Given: The number of new songs that a rock group needs to stay at the top each year is inversely proportional to the year and that the group has been in the industry.
Let x be the number of songs will be needed after 5 years.
Now the inverse variation equation for the given question will be:-
Hence , the number songs will be needed after 5 years = 30
When the numerator is smaller then the denominator..
example : 3/4 or 1/5...it is a proper fraction
