Find the perimeter of a tringle that had sides 1 1/8 1 3/8 1 5/8a) 4 ⅛b) 160.875c) 4.5d) 3 ⅛ what's the answer

3 1/8

Step-by-step explanation:

3 1/8 because p = a + b + c.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

c
