Question

1.Calculeaza media aritmetica a numerelor
a)1,025 si 3701
b)2013+45 si 794,32
2. -------- II -------- II -------- I unui dreptunghi cu L = 7,3 si l= de 3 ori mai mica decat L

Answer 1

1. a) (1,025+3701):2= 3702,025:2= 1851,0125

b) 2013+45= 2058

(2058+794,32)÷2 = 2852,32÷2= 1426,16

2. l= 7,3:3 <=> l= 2,43

(7,3+2,43):2=9,73:2= 4,86
