The answer is 15! Because 5x3 is 15
From V= 4/3*pi*r^3
<span>dV/dt = 4pi(r^2)dr/dt </span>
<span>so when dV/dt=30 and r = 19 </span>
<span>30 = 4pi(361)dr/dt </span>
<span>dr/dt = 30/[4pi(361)] </span>
<span>now in </span>
<span>A = 4pir^2 </span>
<span>dA/dt = 8pi(r)dr/dt </span>
<span>= 8pi(19)*30/[4pi(361)] </span>
<span>= you finish it.</span>
<span>HOPE THIS HELPS.

The number can be separated into 35+0.125
0.125 can be rewritten as,
So, the number can be rewritten;
35+
35
Fractions that aren't equivalent would be 30/60, 34/60 and anything that cannot be the same as 36/60.
