Step-by-step explanation:
15/4x6/5 = 3/2x3 = 9/2
The first answer is C.
The second answer is A.
Either 175.25 ( 175.2 + 0.1/2) or 175.15 ( 175.2 - 0.1/2) ----------> Range. 175.15 < weight < 175.25
Answer:
c = √85
c = 9.2
Step-by-step explanation:
a² + b² = c²
7² + 6² = c²
49 + 36 = c²
85 = c²
c = √85
c = 9.2
