Help!!!

1. which of the following is greater than 4.3 x 10>9?

a 2.1 x 10>9

b 3.2 x 10>9

c 5.3x 10>9

d 7.4 x 10>8

2. which of the following is less than 6.5 x 10>-5?

a 1.4 x 10>-3

b 2.5 x 10-4

c 7.8 x 10-5

d 4.6 x 10>-6

according to the 2010 census the population of Nebraska was 1.8 x 10>6 people. which state had a smaller population?

Ca 3.7 x 10>7

RI 1.1 x 10>6

TX 2.5 x 10>7

MI 6 x 10>6

4. Which number is greater than 5.5 x 10>-7 and less than 5.5 x 10>7?

a 1.8 x 10>12

b 6.7 x 10>8

c 5.2 x 10>3

d 3.9 x 10>-8

1c. 5.3*10^9.

2d 4.6*10^-6 = 0.46*10^-5.

3. RI: 1.1*10^6.

4c. 5.2*10^3.

To compare numbers written in scientific notation, you need to compare the values of the coefficients and the exponents separately.

1. To determine which of the numbers is greater than 4.3 x 10>9, compare the coefficients (the numbers in front of the "x") first. In this case, the coefficients are 2.1, 3.2, 5.3, and 7.4. Since 7.4 is greater than the others, we can eliminate options A, B, and C. Therefore, option D (7.4 x 10>8) is the only number greater than 4.3 x 10>9.

2. Similarly, to find the number less than 6.5 x 10>-5, compare the coefficients. The coefficients are 1.4, 2.5, 7.8, and 4.6. Pick the smallest among these, which is option D (4.6 x 10>-6).

3. To determine which state in the given population options has a smaller population than Nebraska (1.8 x 10>6), compare the coefficients again. The coefficients are 3.7, 1.1, and 6.0. Among these, 1.1 is the smallest, so option RI (1.1 x 10>6) has a smaller population than Nebraska.

4. Lastly, to find the number that falls between 5.5 x 10>-7 and 5.5 x 10>7, compare the coefficients. The coefficients for the given options are 1.8, 6.7, 5.2, and 3.9. The only coefficient that falls between 5.5 and -7 and 5.5 x 10>7 is 6.7. Therefore, option B (6.7 x 10>8) is the answer.
