I think that would be a right angle triangle or is that not what it is meaning
Answer:
It seems there's more information in you question that you haven't posted.
7 months = 7 * (365/12) = 213 days
The half-life of chromium 51 is 27.7 days.
After 7 months, chromium 51 will have undergone 7.69 half-lives.
To solve for the ending amount we'll use the formula:
Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives
We'll say the beginning amount =1
Ending Amount = 1 / 2^7.69
Ending Amount = 0.0048426082
Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

Step-by-step explanation:
Calm Down this is a nasty proof
CB is parallel to ED (Given)
CB is congruent to ED (Given)
Angle CBF is congruent to Angle EDF (Vertical Angles)
Angle DEF is congruent to Angle BCF (Alternate Interior Angles)
Angle EDF is congruent to Angle CBF (Alternate Interior Angles)
Therefore we now have enough information to solve. We have a side angle side triangle here so.....
Triangle CBF is congruent to Triangle EDF because of the Side Angle Side Theorem.
Good Luck and Your Welcome
2.95 per movie....39.95 per month
the yearly cost would be :
39.95(12) + 2.95x....and if u need it simplified more, it would be :
479.40 + 2.95x
