the percent of moisture that falls as snow rather than rain is approximated by P%=10.0 ln h-80,where P is the percent of snow moisture at an altitude h feet. What altitude corresponds to 5 percent snow moisture? Round to the nearest hundred feet.
\n" ); document.write( "--------
\n" ); document.write( "P% = 10*ln(h-80)
\n" ); document.write( "----
\n" ); document.write( "Your Problem:
\n" ); document.write( "5 = 10*ln(h-80)
\n" ); document.write( "ln(h-80) = 1/2
\n" ); document.write( "h-80 = e^(1/2) = 1.65
\n" ); document.write( "---
\n" ); document.write( "height = 81.65 ft
\n" ); document.write( "height = 100 ft when rounded to the nearest hundred
\n" ); document.write( "=============
