Answer:
yes u right
Step-by-step explanation:
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 probability of an event is considered fair when the probability of the event happening is equally likely.

Answer:
51 minutes!
Step-by-step explanation:
<em>Hello there fellow human!</em>
First off, you convert kilometers to miles.
1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles
Next, you determine how many minutes it takes for John to cover 1 mile
which is gotten by dividing 41 by 4;
41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)
Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>, 10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles.

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.
Answer:
x = 10
Step-by-step explanation:
Since the parallelograms are similar then the ratios of corresponding sides are equal , that is
= ( cross- multiply )
6x = 60 ( divide both sides by 6 )
x = 10
