A lawnmower weighing 15 kg is packed in a box weighing 2 kg. Both these masses are measured to the nearest kg.
What is the greatest possible total mass of a lawnmower and its box?
a
b
The boxed lawnmowers are loaded in a van. The maximum load that the van can
carry is 200 kg. Calculate the maximum number of boxed lawnmowers that the
van can carry.

Please have a more elaborated question

Step-by-step explanation:

Tried my best

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
