One metric ton equals how many kilograms

Write 5 numbers that round to 740 when rounded to the nearest 10

Me. i can't figure out this question. give an explanation too. .

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
