Considering balloon to be an spherical object
Volume of sphere =
, where r is the radius of sphere.
After 19 minutes ,If radius of balloon changes from r to R, the Volume changes from V to V'.
V'=
,
As given,rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon.
Also,
Now, again the radius changes from R to r.So, Volume changes from V' to Back to V.
Time taken by the balloon to deflate = 38 minutes
But there is no relation between time and volume of Balloon.
So, we can't predict at which rate balloon is deflating or inflating.Apart from the statement given in Question:
Answer:
Your answer is Taylor
Step-by-step explanation:
<span>She could round this number
may it be in the tens and hundreds place. When rounding off a number, one
should consider the place of the digit he or she would like to round it off to.
One should consider what number is placed at the right of the rounding number.
If the number is below 5, then that digit should remain and the rest of the
digits to the right should be turned to 0s. </span>
