What is square root of 685 to the nearest integer and tenth

26

Step-by-step explanation:

The actual answer is 26.1725047... but when we simplify the answer to the nearest integer we get 26. To get 26 you round down from the actual answer. To round, remember it like this "if the answer is five or more let it soar (round up); if it is four or less, let it rest (round down)."

And that's how you get your answer

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

probability for j is 1/4

while

a is 1/6
