Acomputer printer can print a 660-word document in 35 seconds. at this rate, how many seconds are required to print a document that contains 840 words?

Set up a proportion:

The numerator represents the words in the document, and the denominator represents the seconds it takes to print the document.

You can simplify the first fraction to make multiplication easier. Divide both the numerator and denominator by 5:

Cross multiply both fractions:

Divide both sides by 132 to get x by itself:

It will take 44.54 seconds to print the 840-word document.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

goog may have it for you
