A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro what is the total number of minutes talked if the cost of the call was 7.14 euro

Total minutes = 47 Minutes

Step-by-step explanation:

A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro

Expressing the statement in mathematical terms;

Cost = 0.12x + 1.5 where x represens minutes

if the cost of the call was 7.14 euro, total minutes  = ?

7.14 = 0.12x + 1.5

7.14 - 1.5 = 0.12x

5.64 = 0.12x

x = 5.64 / 0.12 = 47

Total minutes = 47 Minutes

the answer is 15% decrease

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
