According to the u. s. census bureau, about 63% of americans are adults (18 and over). use the u. s. population estimate of 308 million people to calculate the number of american adults in 2010. round to the nearest hundred thousand adults.

194,000,000

Step-by-step explanation:

Given : According to the U.S. Census Bureau, about 63% of Americans are adults (18 and over).

We can rewrite 63% as 0.63 [ ∵ we divide 100 to convert a percent into decimal]

The estimated population of U.S  in 2010= 308 million

We know that 1 million = 1,000,000

⇒The estimated population of U.S  in 2010= 308,000,000

Now, the number of American adults in 2010 will be :-

 [Roundedto the nearest hundred thousand]

hence, the approximate number of American adults in 2010= 194,000,000

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
