If y varies as x, and x = 9 when y = 15, find y when x = 33.

To find the value of y when x = 33, we need to determine the relationship between y and x. In this case, it is given that y varies directly as x. This means that the ratio of y to x remains constant.

We can express this relationship using the equation y = kx, where k is the constant of variation. To find the value of k, we can use the given information that when x = 9, y = 15.

Substituting these values into the equation, we have 15 = k * 9. We can solve for k by dividing both sides of the equation by 9: k = 15/9 = 1.67 (rounded to two decimal places).

Now that we have the value of k, we can use it to find y when x = 33. Substituting the values into the equation, we have y = 1.67 * 33.

Calculating this expression, we find y = 55.11 (rounded to two decimal places).

Therefore, when x = 33, y is approximately 55.11.
