In a sale, normal prices are reduced
by 25%.
The sale price of a calculator is
£8.82

2.2050

Step-by-step explanation:

25% -> 2500.

25% is just a way of saying 25 out of 100. So we have to times 25 by 100 which gets you 2500. You the have to multiply 2500 by 8.82 which will get you 22050. Now the price is reduced by 25% so the answer will be less than 8. You have to add a decimal somewhere in the number 22050 and it has to be less than 8. You could but it after the second 2 but then it will be over 8. So the only spot you can put it is after the first 2 like this 2. so the answer will be 2.2050

answer is:

1.75 pounds

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
