Answer:
367meters
Step-by-step explanation:
220.2 = 0.6 * h
220.2/0.6 = 0.6 * h / 0.6
367 = h
367 meters
Half life means only half of matter is left, which means half is decayed/radiated.
Formula for half life is
t/2 = [(elapsed time)*(log2)]/[log(beginning amount/ending amount)]
1. t/2 = [(10)*(log2)]/[log(100/76.1)] = 25.378 minutes.
t/2 = [10 * 0.301]/[log 1.314] = [3.01]/[0.1186] = 25.378
2. 53.12 = [(T)*(log2)]/[log(15/4)], on solving we get, T = 101.29 days
53.12 = [T * 0.301]/[log 3.75] = [0.301 * T]/[0.574],
T = [53.12 * 0.574]/[0.301] = [30.49]/[0.301] = 101.29<span />
The solution for the given inequality, m < 3 is 2. According to the inequality, the possible values for “m” must be lesser than 3.
A) x<-2 and x<0 , the have the same part x<-2, so it has a solution
B) x≤ 0 and x<span> ≥0, the have the same part x=0
C)x<0 and x>0 , the do not have points that belong both inequalities , so
C has no solutions</span>
Answer: 5 meters.
Step-by-step explanation:
When a circle circumscribed about a rectangle,
Then the diameter of the circle = Diagonal of the rectangle,
Here, the length of the rectangle = 8 cm,
And, the width of the rectangle = 6 cm,
Thus, the diameter of the circle = 10 meters
⇒ Radius of the circle = diameter/2 = 10/2 = 5 meters.
