Answer:
135.1 cm
Step-by-step explanation:
The Pythagorean theorem tells you how to find the hypotenuse of a right triangle with legs 120 and 62:
diagonal = √(120² +62²) = √18244 ≈ 135.07
The length of one of the braces is about 135.1 cm.
23° 20' 48" in degrees
Minutes are 1/60 of a degree and seconds 1/60 of a minute.
Let's convert the 48" to minutes.
48/60 = 0.8
23° 20' 48" ⇒ 23° 20.8'
Let's convert the 20.8' to degrees.
20.8/60 ≈ 0.3466667
23° 20.8' ⇒ 23.35°
Answer:
20 books
Step-by-step explanation:
given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)
number of books which the shelf can hold
= weight that the shelf can hold ÷ weight of each book
= 25.5 ÷ 1.25
= 20.4 books
because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)
20.4 books rounded down to nearest whole number = 20 books (answer)
