Zarin drinks 16 glasses of water in one day. If she drinks same amount of water every day, then how much water does she drink in one week?

the answer is 112 glasses of water.

Step-by-step explanation:

let's use a proportion method

16glasses=1 day

and the whole week is composed of 7 days this means that:

7 days= 16*7=112 glasses of water

112

Step-by-step explanation:

because 16 * one week ( 7 ) = 112

16 x 7 = 112 ..

the graph on the bottom right

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)
