Question

Calculati ma a nr.
a) (12,1-11,9)/4+4,5 si y=[(2,3+1,5)*12,5]/(2,05-125);
b) [(3,15+4,05)*36,9]/[(17,5-10,3)*0,41} si y=21,7*(11,8-4,5).

Answer 1

a) (12,1-11,9)/4+4,5 = 0.2 / 4 + 4.5 = 4.55

y=[(2,3+1,5)*12,5]/(2,05-1,25)

= (3.8 * 12.5) / 0.8)

= 47.5 / 0.8 = 59.375

ma = 31,9625

b) [(3,15+4,05)*36,9]/[(17,5-10,3)*0,41}

= (7.2 * 36.9) / (7.2*0.41)

= 265.68 / 2.952 = 90

y=21,7*(11,8-4,5) = 21,7 * 7,3 = 158.41

ma = 124,205
