There are approximately 314 million people in the u. s. if the world population is 7.1 billion people, what percent of the world population is in the u. s.?

The U.S population is 4.42% of the world population.

Step-by-step explanation:

The population is U.S = 314 million

World population = 7.1 billion

Let's convert 7.1 billion to million.

1 billion = 1000 million

NOw multiply 7.1 billion by 1000 to get million.

7.1 billion = 7.1*1000 million = 7100 million

Percent = (U.S  population / World population)*100

Percent of U.S population =

= 314/71

= 4.42%

Therefore, the U.S population is 4.42% of the world population.

sorry if this isnt what you're looking for i dont really understand the question

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
