Answer:
1.753 g
Step-by-step explanation:
Half life of Einsteinium = 20.5 days
Time elapsed = 31 days
Initial quantity of the substance = 5g
The formula to apply is;

Where
N(t)=quantity of a substance remaining
No =Initial quantity of the substance = 5g
t= time elapsed=31 days
t1/2 = half life of the substance= 20.5 days
N(t)=5 * {1/2} ^ {31/20.5}
N{t} = 5 * {0.5}^1.5
N{t} = 5*0.3506
N{t} =1.753 g
Answer:
N/A
Step-by-step explanation:
The question is not solvable if it were 100-(x + 12)=x the answer is 44
Answer:

Step-by-step explanation:
Greatest multiplier of 4 that is less than 21 is 5 (4 x 5 = 20)
Put the remaining number as the numerator (21 - 20 = 1)
Both angles equal 117 so you put both angle equations together and set them equal to 117 then x= -2
Plug the -2 in for the x in both separate equations to get
M< XYW = 32°
M< WYZ = 85°
