Acafe sells puffs. 5/9 are beef and 1/3 are chicken. the remaining 18 are tuna. calculate 1. what fraction of the puffs are tuna and 2. how many puffs are there in all. i really need to see the working for this.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

27 +27 or 27times 2=54

the diffrence is 0
