Answer:
50
Step-by-step explanation:
Answer:
m∠1 = 50°
m∠2 = 130°
Explanation:
m∠2 = 130° because of alternate exterior angles.
m∠1 = 50° because it is supplementary to m∠2. So, 180 - 130 = 50.
The answer is 3x+15
You multiply the x and 5 by 3 to get 3x and 15
For the half-life of a certain substance, the equation that would best represent the scenario is,
At = Ao(0.5^t/n)
where At is the amount at any time t, Ao is the original amount, and n is half-life. Substituting the known values,
At = (220 mg)(0.5^(396/72)
At = 4.86 mg
Thus, after 396 days, there will only be 4.86 mg of Terbium-160.
