There are four brands of smartphones that are most popular in the united states . the number of people in the united states that have each brand is given. brand a; 4.48x104; brand b : 3.84 x107; brand c : 6.4x10^6; brand d: 1.50 x107 what is the order of these brands from most to least popular?

For this case we must write the numbers from highest to lowest.

We observe that the numbers are written in exponential notation.

Therefore, by rewriting we have:

Brand A:

Brand B:

Brand C:

Brand D:

Ordering from highest to lowest we have:

The order of these brands from most to least popular is:

Brand B

Brand D

Brand C

Brand A

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
