Answer:
59.44%
Step-by-step explanation:
<em>
</em>
<em>
</em>
<em>Where
= mass remaining</em>
<em>
=original mass.</em>
<em>t= time </em>
<em>
=half life</em>
=1599, t= 1200,
=226,
=?

n= 0.750469

=134.3367amu
percentage of mass remaining =
*100%
= 59.44%
Answer:
3x -2y = -14
Step-by-step explanation:
The parallel line will have a new constant that can be found by substituting the given point for x and y.
-3x +2y = -3(0) +2(7) = 14
An equation for the parallel line is ...
-3x +2y = 14
__
In standard form, the leading coefficient is positive, so the standard form equation is ...
3x -2y = -14
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
