Answer:
6 7/8
Step-by-step explanation:
Take a quick look at those fractions. The LCD here is 8. We'll leave 4 5/8 as is, but change 2 1/4 to 2 2/8.
Now we'll add together:
4 5/8
+ 2 2/8
-----------
6 7/8

Answer:
3 ≤ n ≤ 10 means "three is less than or equal to n, which is less than or equal to 10"
you're concerned with polygons having 3 to 10 sides, inclusive.
Step-by-step explanation:
The symbol ≤ means "less than or equal to." The compound inequality ...
3 ≤ n ≤ 10
means the value of n may range from 3 to 10, inclusive.
__
In the present context, where n is a number of sides, it means you're concerned with polygons that are any of ...

Step-by-step explanation:

When zero is added to or subtracted to a number, the number is not affected.
You use the formula below...,
Angle theta = cos^-1 [scalar product of the two vectors ÷ multiplication of their moduli]
For example...the angle between
(2i + 3j) and (4i + 5j)
Angle theta = cos^-1 [( 2(4) + 3(5))÷((square root of (2^2 + 3^2))×(square root of (4^2 + 5^2))
Angle theta = cos^-1 [ 23 ÷ ((square root of(13)) × (square root of (41)]
Angle theta = 5°
