Answer:
3.1 x 10^9
Step-by-step explanation:
(2.8 x 10^9) + (3 x 10^8) = (28 x 10^8) + (3 x 10^8)
= (28+3) x 10^8
= 31 x 10^8
= 3.1 X 10^9

The dimension of an object is a topological measure of the size of its covering properties. Roughly speaking, it is the number of coordinates needed to specify a point on the object. For example, a rectangle is two-dimensional, while a cube is three-dimensional. The dimension of an object is sometimes also called its "dimensionality."
Answer:
66.67%
Step-by-step explanation:
We know that a foot is equal to 12 inches.
First, we write it in the form of a fraction.
8 inches of a foot = 8/12
Then we simplify the fraction.
8/12 = 2/3
After that, to write the number in percentage form, we need to multiply the fraction by 100%.
2/3 x 100% = 66.67% (Nearest hundredth)
