A sled sells for $40 is on sale for $28. By what percent is the price reduced?

40-28-12    

12/40 = 0.3

0.3 = 30%

Step-by-step explanation:

The price is reduced by 30 percent

Step-by-step explanation:

the price was reduced by 30 percent how I got the answer was taking by taking 100 dividing it by 40 then multiplying it by the new number 28, with this it gives you 70 and that means it is 70 percent of the whole answer 40 so that's how you get 30 percent as the reduction.

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°
