1. iris has two ribbons. the first ribbon is 11.7 in. long. the second ribbon is 5.25 in. long. she wants to cut them so that they are the same length.

(a) estimate the difference between the ribbon lengths.

(b) will your estimate be high or low? explain.

(c) how much does iris need to cut from the longer ribbon to make the ribbons the same length?



, (not a choice question)

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

1/800 is the right answer
