Answer:
sorry sir i really dont even understand
3.75 is the correct answer
In order to figure out the half-life, you divide to sample by 2. In order to find how many times to divide it you divide 15 by 3 and get 5. Therefore, you divide 120 by 2, 5 times and get 3.75
Perimeter = 56
Hypo = 25
So 56-25 = 31 (for two side)
for one side = 31/2 = 15.5
so area = 1/2 x base x height
X = 1/5 ÷ 3/4
x = 1/5 × 4/3
x = 4/15
the answer is C
