A plane has an airspeed of 175 miles per hour and heading of 30.0 . The ground speed of the plane is 206 miles per hour, and its true course is the direction of 34.0 . Find the speed and direction of the air currents, assuming they are constants. Apply the rules regarding the use of significant digits after all computations are complete.

445

Explanation:

175+30.0+206+34.0=445 lol

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
