Question

when determining soil texture, the percentages of the three soil particle types add up to 100%. if a soil had 10% clay and 10% silt, what would be the percentage of sand? 10% 40% 80%

Explanation:

Step1: Set up the equation

Let the percentage of sand be $x$. We know that the sum of the percentages of clay, silt, and sand is 100%. So, $10\%+ 10\%+x = 100\%$.

Step2: Solve for $x$

$x=100\%-(10\% + 10\%)$.
$x = 100\% - 20\%$.
$x = 80\%$.

Answer:

C. 80%
