Arestaurant built a ramp to make their facility more accessible to people in wheelchairs. they covered the entire surface of the ramp with metal to make it more durable. how much metal did they use to cover the ramp, including the bottom?

picture below

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)

what is the answer?
