Please help me on a test 2 3/4 + 5 1/2
drek231 [11]

Answer: 8 1/4

Step-by-step explanation:

2 3/4 + 5 1/2 = ?

Least common denominator is 4

2 3/4 + 5 2/4 = ?

2(4)+3 = 11

5(4) + 2 = 22

so the equation becomes

11/4 + 22/4 = 33/4 = 8 1/4

'Polonium-210 is a radioactive substance with a half-life of 138 days. If a nuclear
Tatiana [17]

Answer:

  • <u>59.0891 g (rounded to 4 decimal places)</u>

Explanation:

<em>Half-life time</em> of a radioactive substance is the time for half of the substance to decay.

Thus, the amount of the radioactive substance that remains after a number n of half-lives is given by:

  • A=A_0\cdot (1/2)^n

Where:

  • A is the amount that remains of the substance after n half-lives have elapses, and
  • A₀ is the starting amount of the substance.

In this problem, you have that the half-live for your sample (polonium-210) is 138 days and the number of days elapsed is 330 days. Thus, the number of half-lives elapsed is:

  • 330 days / 138 days = 2.3913

Therefore, the amount of polonium-210 that will be left in 330 days is:

  • A=310{g}\cdot (1/2)^{2.3913}=59.0891g
