What is the minimum amount of time required to perform all five activities?

7 hours or 420 minutes.

Step-by-step explanation:

0.5 = 30 minutes  

1.0 = 60 minutes

2.0 = 120 minutes

1.5 = 90 minutes

2.0 = 120 minutes

= 420 minutes

Every hour is 1.00 so 0.5 would be 30 minutes. I'll allow you to add up the time now.

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.
