4 hours
Jaquan can read 1/16 of a book in 1/2 an hour, so he can read 2/16 or 1/8 of a book in one hour (multiplying both by 2). Since we are looking for when he finishes half the book (1/2 or 4/8), we are looking for how many hours it takes at a rate of 1/8 books/hr to read 4/8 of a book.
Thus, 1/8x = 4/8, solved for x = 4

Answer:
Step-by-step explanation:
The equation for a circle is given by:
Where (h,k) is the center and r is the radius.
The center is the red dot, which is (1,2). Thus, h=1 and k=2.
To find the radius, you need to use the distance formula. We are given two coordinates: the center (red dot) at (1,2) and a blue dot on the circle at (2.5,4). Find the radius by using the distance formula:
Let (1,2) be <em>x₁ </em>and <em>y₁ </em>and let (2.5,4) be <em>x₂ </em>and <em>y₂. </em>Therefore:
Thus, r is 2.5.
Plugging these numbers into the equation, we have:
