Sarah and her 4 friends share some cookies. if each person gets 3 cookies, how many cookies were shared?
write a mathematical equation that represents this situation.
c/5 = 3
c/4 = 3
4c = 3

c/5 = 3

Step-by-step explanation:

Sarah + 4 friends = 5

if each person gets 3 cookies,

ie. 1 = 3

5 = c

cross multiplying,

3 × 5 = c

so, c\5 = 3

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
