Answer:
(10/12) / (4/6)...when dividing with fractions, flip what u r dividing by, then multiply
10/12 * 6/4 = 10/8 which reduces to 5/4 or 1 1/4
Not enough information. How many segments does the arm have?
Answer:
Option D is correct.
Explicit formula for the geometric sequence is, 
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
.....[1] where
is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term (
) = 64.
Common ratio(r) = 0.5
Since,

,
......
Substitute the value of a and r in [1] we get;

therefore, the explicit formula for the geometric sequence is, 
Answer:
42in :)
Step-by-step explanation:
All you have to do is multiply 7x6 because u need to find the area.
but if u wanna find the perimeter u have to add all sides.
area is multiply 2 sides.
