The variables t and u are inversely proportional to each other. What t= 7, u 3, what is the value of t when u =21?

Answer 1

Since t and u are inversely proportional, we can set up the equation:

t * u = k

where k is the constant of proportionality.

Given that t = 7 and u = 3, we can substitute these values into the equation:

7 * 3 = k
k = 21

Now, we can use the value of k to find t when u = 21:

t * 21 = 21
t = 21 / 21
t = 1

Therefore, when u = 21, t = 1.
