Larry has a clay brick that is 7 inches long, 5.5 inches wide, and 2.75 inches thick, the same size as the gold stored in a vault in the form of gold bars. find the volume of this brick. if the weight of the clay in the brick is 0.1 pound per cubic inch and the weight of the gold is 0.7 pound per cubic inch, find the weight of the brick and the gold bar. round all answers to the nearest tenth.

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 correct answer is x/3+10≥32

hope this !
