Courtney reads about 110 words per minute she procrastinated and now has less then a week to finish her reading assignment if the book she needs to finish has another 820 pages left and each page with about 350 words how many hours should she set aside to complete her assignment

Multiply the amount of pages by the amount of words per page:

There are about 287000 words remaining.

Courtney can read at a rate of 110 words per minute. Since we want to find the amount of hours she needs to finish the book, multiply this rate by 60 to convert into an hour:

Courtney reads at a rate of 6600 words per hour.

Divide the amount of words in the book by Courtney's reading speed in hours:

Courtney will need to set aside 43.48 hours to complete her assignment.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
