Step-by-step explanation:
step 1
Find the volume of the a cube shape tank
The volume is equal to

we have

substitute

step 2
Find the volume of cone
The volume is equal to

we have



substitute


step 3
Find the difference of the volumes

The percent of decrease would be 60%
Answer:
72
Step-by-step explanation:
In order to find the acceleration we need first to defined it, so:
acceleration=((final velocity)-(initial velocity))/time interval

But (vf-vi) actually represents the velocity change, so (vf-vi)/dt represents the velocity change rate. This means that in our case:


In conclusion the acceleration is
, without units just 72.
