Answer:
There are 1,500 books in Library 1
Step-by-step explanation:
30 = 0.02x
Divide 0.02(or 2%) from both sides
1,500
You need to divide the 20 books by the percentage that they are compared to the total amount.
To find the total number of books in Library 1, we can use the concept of percent. We are given that 30 books represent 2% of the total books in Library 1. By setting up and solving an equation, we find that the total number of books in library 1 is 1500.
To find the total number of books in Library 1, we can use the concept of percent.
Let's represent the total number of books in library 1 as x.
We are given that 30 books represent 2% of the total books in Library 1.
So, we can set up the equation:
2% of x = 30
To solve for x, we need to isolate it on one side of the equation. To do this, we can divide bothsides of the equation by 2% or 0.02.
x = 30 ÷ 0.02 = 1500
Therefore, the total number of books in Library 1 is 1500.

The area of this rectangle is 9/20 miles squared, then the width of the rectangle exists 1/2.
A rectangle is a shape with only two dimensions. It is a quadrilateral whose opposite sides are each the same length and parallel, and whose four interior angles are each 90° (circ). As an equiangular quadrilateral, it is also known. The length and width of a rectangle are its longer and shorter sides, respectively.
To find the area of a rectangle:
a = l × w
Where l is the length and w is the width.
length: A= 9/10 miles
Area: w = 9/20 miles
Area = length × Width
9/20 miles = 9/10 miles × Width
Width = (9/20 miles) / (9/10 miles)
simplifying the above equation, we get
= 10/20
Cancel the numbers: 10/20 = 1/2
= 1/2
Therefore, the area of this rectangle is 9/20 miles squared, then the width of the rectangle exists 1/2.

Width=Area/Length
Area=9/20(.45)
Length=9/10(.9)
w=.45/.9
w=1/2
Therefore, the width is 1/2(.5)
