Answer:
Sum is 1836.
Step-by-step explanation:
As we know,
average= sum/total numbers
153=sum/12
153*12=sum
sum=1836
The ration is 170 adults:150 children, or 170/150We can factor out a 10 from both numbers, which leaves us with
17 adults/15 children.17 and 15 have no other factors, so that's the smallest ratio we can have.
The rate of change of the height is
in/min.
<h3>What is a right circular cylinder?</h3>
A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder.
Volume of the cylinder = 
Rate of change of height is
= ?
At any time t,
Volume, V = 
Since r does not change with time, then r is a constant, so,
V = 
V = 
Differentiate both sides with respect to time t,
-------------(i)
Since
is given as 4
cu.in. per min,


in/min.
Hence, The rate of change of the height is
in/min.
