1. (5 pt) kevan has 26 goats in his herd, and 12 of them are male. what is the ratio of female goats to male goats? a. 7 : 6 b. 6 : 7 c. 7 : 19 d. 6 : 19

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)
