T=(D)/(R). if T=25 and D=75, Then R is equal to

A.50
B.3
C.25
D.75
E.1/3

1 answer

To find R, we can rearrange the equation \( T = \frac{D}{R} \) to solve for R:

\[ R = \frac{D}{T} \]

Now, plug in the values for D and T:

\[ D = 75 \quad \text{and} \quad T = 25 \]

Substituting these values into the equation gives:

\[ R = \frac{75}{25} \]

Calculating this:

\[ R = 3 \]

Therefore, R is equal to 3. The correct answer is B. 3.
