What percent of a present amount of radioactive radium (226Ra) will remain after 1200 years? The half life of 226Ra is 1599 year
sp2606 [1]

Answer:

59.44%

Step-by-step explanation:

<em>M_{R} = \frac{M_{O} }{2^{n} }</em>

<em>n=\frac{t}{t\frac{1}{2} }</em>

<em>Where M_{R} = mass remaining</em>

<em>M_{O} =original mass.</em>

<em>t= time </em>

<em>t\frac{1}{2} =half life</em>

t\frac{1}{2} =1599,  t= 1200, M_{O} =226,  M_{R} =?

n=\frac{1200}{1599}

n= 0.750469

M_{R} = \frac{226}{2^{ 0.750469} }

M_{R} =134.3367amu

percentage of mass remaining = \frac{134.3367amu}{226amu} *100%

                                                   = 59.44%

Find the equation of a line that is parallel to the line -3x+2y=10 and goes through the point (0,7).
Delvig [45]

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
