Question

question 12
solve the formula for the specified variable.
i=prt, solve for t.
○ $t = \frac{i}{pr}$
○ $t = \frac{pi}{r}$
○ $t = i - pr$
○ $t = \frac{pr}{i}$

Explanation:

Step1: Identify the formula

We start with the formula \( I = Prt \), where we need to solve for \( t \).

Step2: Isolate the variable \( t \)

To isolate \( t \), we divide both sides of the equation by \( Pr \) (assuming \( Pr
eq 0 \)).

So, dividing both sides by \( Pr \):

\( \frac{I}{Pr} = \frac{Prt}{Pr} \)

Simplifying the right - hand side, the \( Pr \) terms cancel out, leaving us with \( t=\frac{I}{Pr} \).

Answer:

\( t = \frac{I}{Pr} \) (corresponding to the first option: \( t=\frac{I}{Pr} \))
