Notice that 50 minutes is twice the half-life.
After 25 minutes, half of the starting amount remains, so that 88g decays to 44g.
After another 25 minutes (a total of 50 minutes), the 44g will decay to 22g.
Answer:
JM ≈ 12.9 miles
Step-by-step explanation:
The length of the arc is calculated as
arc = circumference × fraction of circle
= πd × 
JM = π × 16.4 × 
=
≈ 12.9
25x+ the diameter of a rectangle
Let
x------> the <span>remaining ice cream
we know that
3/10------> 0.30
so
x=1-0.30-0.40-----> x=1-0.70------> x=0.30 gal------> 3/10 gal
the answer is
3/10 gal</span>
