Yes savannah is correct
Expiation 1 kg = 1000g
1 g = 1000 milligrams (mg)
So 1000g X 1000mg
= 1000000 is answer
Expiation 1 kg = 1000g
1 g = 1000 milligrams (mg)
So 1000g X 1000mg
= 1000000 is answer
Answer:
120 grams will be left after 180 years.
Step-by-step explanation:
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by
where,
= quantity of the substance remaining
= initial quantity of the substance
= time elapsed
= half life of the substance
From the information given we know that:
- The initial quantity is 480 g,
- The half-life is 90 years,
- 180 years is the time elapsed.
And we want to find how much will be left. For this we use the above formula.
120 grams will be left after 180 years.
Answer:
d ≈ 87.85 yards
Step-by-step explanation:
The circumference ( C) of a circle is calculated as
C = πd ( d is the diameter ), then
276 = πd ( divide both sides by π )
= d , so
d ≈ 87.85 yards ( to the nearest hundredth )
