Curt just drank a cup of coffee to him stay awake. the coffee had 130 milligrams of caffeine in it. if his body processes 7% of the caffeine every hour, how much will be left in 4 hours?

97.25 milligrams

Step-by-step explanation:

Given: Curt just drank a cup of coffee to help him stay awake.

The initial amour of caffeine in coffee= 130 milligrams

The rate of decay of caffeine in body = 7%= 0.07

We know that the exponential decay equation with rate r and and time t is given by :-

, where A is the initial value.

Now, the amount of caffeine left in body after 4 hours is given by :-

Hence, after 4 hours 97.25 milligrams will be left.

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
