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 rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
