To find the elevation drop between a point above sea level and a point below sea level, you will need to add the absolute values (the distance from zero) to find how far apart they are.
|880| + |-139|=
880 + 139 = 1019 meters
The drop in elevation is 1019 meters.
The total no. of books in the school library= 980
<u>Step-by-step explanation:</u>
Let the total no. of books be 'n'
60% of total books are text books
No. of text books = 588
(60/100) x n = 588
n = 588 x (100/60)
n = 980
The total no. of books in the school library= 980
Answer:
width of the garden is 50 ft and the length is 70 ft
Step-by-step explanation:
Solution:-
- We will denote the width and and the length of the rectangular garden as:
Width: x
Length: x + 20
- We are given the area ( A ) of the garden is 3500 ft^2. We are to determine for what dimensions is the area A = 3500 ft^2.
- Recall that the area ( A ) of a rectangle is the product of length and width as follows:
A = Length * width
A = x*( x + 20 )
3500 = x^2 + 20x
x^2 + 20x - 3500 = 0
- Use the quadratic formula to determine the value of ( x ):
- Ignore the negative value of ( - 70 ft ). Physical impractical to have a negative value. Hence, the width of the garden is 50 ft and the length is 70 ft
