About 1/10 of the bones in your body are in your skull. your hands are about 1/4 of the bones in your body. write and solve an equation to find the fraction of no es in your body that are in your hands and skull.

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)

the answer is (-4,-4)

hope this ! : d
