The event will last approx. two hours, so plan accordingly.

The meeting will start at approx. 3:00 PM, so please be on time.

Our flight is approx two hours behind schedule, so we'll miss the connection.

Please give an approx time of arrival so we can schedule the meeting.

When applying the numerical method, we must first identify the approximand before selecting an appropriate algorithm.

The books on the shelf are arranged approximally, so similar titles sit next to each other.

Researchers compared the approximabilities of different heuristic algorithms on benchmark instances to determine which approach yielded more reliable results.

Researchers are investigating the approximability of various optimization problems to determine which admit efficient heuristics.

That continuous function is approximable on the closed interval, since the Weierstrass theorem guarantees polynomials that approximate it uniformly.

The radiograph revealed an approximal lesion on the first molar that required prompt treatment.
