Question

when determining soil texture, the percentages of the three soil particle types add up to 100%. if a soil had 33% clay and 34% silt, what would be the percentage of sand? 33% 13% 43%

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, $33\%+34\% + x=100\%$.

Step2: Solve for $x$

$x = 100\%-(33\% + 34\%)$. First, calculate $33\%+34\%=67\%$. Then, $x=100\% - 67\%=33\%$.

Answer:

A. 33%
