Acoat was marked down by 60 percent from its original price of $99. including an 8 percent sales tax, what is the final cost of the coat?

$ 42.77

Step-by-step explanation:

Given,

The original price of the coat= $ 99,

Marked down percentage = 60%,

Thus, the price after reduction = 99 - 60% of 99 = 99 - 59.4 = $ 39.6

Now, the sales tax percentage,

Hence, the final cost of the coat after applying sales tax

= 39.6 + 8% of 39.6

= 39.6 + 3.168

= 42.768

≈ $ 42.77

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°
