Answer:</u></h2>
The roofing company can take out <u>196.352kg</u> of shingles.
<h2><u>
Step-by-step explanation:</u></h2>
- First, work out how many 90 minutes are in 39 hours:
39 x 60 = 2340 minutes total
2340 ÷ 90 = <u>26</u>
- Then, multiply this by 755.2 to work out how much hectograms of trash is taken out.
26 x 755.2 = <u>19635.2 hectograms of trash</u>
- Finally, divide this by 10 to work out how many kilograms this is:
19635.2 ÷ 10 = <u>196.352kg</u>
So, 3 goes into 8 2 times and 2 will be left over so you would put:
2 2/8 or 2 1/4
11 books;
157 books - 102 books = 55 books (donated)
55 books divided by those 5 months in between is 11 books
Square foot is 12 inches x 12 inches which is 144 inches so it would be 1/144
