18. Chicken patties are sold in packs of 8. Buns are sold in packs of 10. What is the least number of chicken patties & buns needed so that no food is wasted?

5 packages of patties = 40

4 packages of buns =40

4 packages of buns, and 5 packages of chicken patties.

Step-by-step explanation:

8 = 2 X 2 X 2

10 = 5 X 2

The Least Common Multiple of 8 and 10 = 2 X 2 X 2 X 5 = 40, now divide 40/10 = 4 and 40/8 =5 therfore you need to buy: 4 packages of buns, and 5 packages of chicken patties.

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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
