That would be 5/8
------------------------
Jamie has 6 pairs of boots.
the ratio 3:6 is equivalent to 1:2. for every 1 boot there are 2 sneakers. so, 12/2 = 6.
Answer:
Step-by-step explanation:
For a first order decay, fraction remaining = 0.5n where n = number of half lives elapsed.
fraction remaining = 55% = 0.55
0.55 = 0.5n
log 0.55 = n log 0.5
-0.2596 = -0.301 n
n = 0.8625 = # of half lives elapsed
0.8625 half lives x 2.5 billion years/half live = 2.16 billion years have elapsed = age of the rock
b) 0.15 = 0.5n
log 0.15 = n log 0.5
-0.824 = -0.301 n
n = 2.74 half lives
2.5 billion years/half life x 2.74 half lives = 6.85 billion years = age of rock
Answer:
-3.7
Step-by-step explanation:
i think this is right if you meant to say find instead of fine
Its B or D!
I hope this helps!
take a lucky guess!
