Quizplus · Accepted Answer

Given the formula $d=\frac{D W}{W}$, when $d=10$, $w=12$, and $W=2$, we can solve for $D$ by rearranging the formula to $D=\frac{dW}{w}$. Substituting the given values, $D=\frac{10*2}{12}$, which simplifies to $D=20/12=5/3$, or approximately $1.67$, which is not among the provided options. However, the correct interpretation of the formula should be $d=\frac{D W}{w}$ based on the variables provided, leading to $D=\frac{dw}{W}$. Substituting the given values, $D=\frac{10*12}{2}=60$.
