What is an estimation strategy<br> This is for 6th grade math please help
Lunna [17]

Answer:

Estimation is a mental process of coming up with an answer that is relatively  close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.

An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.

In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?<br>​
ikadub [295]

Answer:

An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being  produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.

They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.
