The world cup is an international soccer tournament. there were about 15,470,000 viewers in the united states that watched it on television. which shows the number of viewers rounded to the nearest ten million? 20,000,000 10,000,000 16,000,000 15,000,000 which one?

the ten million place will be two to the left of your first comma shown.

15,470,000

Look at the number just to the right. If it is larger than 4, we need to round up. It is, so we need to round the 1 to a 2 and the rest of the numbers become zeroes.

20,000,000 is the correct answer.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
