Transcript text: Solve the formula for the specified variable.
\[
D=\frac{1}{3} f k \text { for } k
\]
\[
\mathrm{k}=\square
\]
(Simplify your answer.)
Solution
Solution Steps
To solve for \( k \) in the equation \( D = \frac{1}{3} f k \), we need to isolate \( k \). This can be done by multiplying both sides of the equation by the reciprocal of the coefficient of \( k \).
Step 1: Given Equation
We start with the given equation:
\[
D = \frac{1}{3} f k
\]
Step 2: Isolate \( k \)
To isolate \( k \), we multiply both sides of the equation by the reciprocal of \( \frac{1}{3} f \):
\[
k = \frac{3D}{f}
\]
Step 3: Substitute Given Values
Substitute the given values \( D = 10 \) and \( f = 5 \) into the equation:
\[
k = \frac{3 \times 10}{5}
\]
Step 4: Simplify the Expression
Simplify the expression to find \( k \):
\[
k = \frac{30}{5} = 6.0
\]
