Answer:
he put it on one brownie so 1/7
One Half-Life of polonium = 138 days
We have to find the number of half-lives that occur in 1104 days. For this we simply divide 1104 by 138.
Number of half-lives in 1104 days = 1104/138 = 8 half-lives
Thus, in 1104 days polonium-210 undergoes 8 half-lives i.e. it is halved 8 times.
Initial Amount of sample= 30 gram
The amount remaining after 8 half-lives will be = 30 x (0.5)⁸ = 0.1171875 grams.
This means, after 1104 days, 30 gram sample of polonium-210 will be reduced to 0.1171875 grams only.
Answer:
No, Ssa triangle always not have two solutions
Step-by-step explanation:
the solution can be one, two or there will be no dolution. So this statement is false.
Since you move the decimal two times to the right to get 0.75, you multiply 0.0075 by 100 to get 0.75.
Hope this helps!
The correct answers for these is A,C,D. How I got this was by plugging in (x,y) to the equation. This means that I plug in x and y from the point into the equation and simplifying it to see if it gets the right answer.
