Which set of numbers is arranged in descending order? (1 point)
0 7 × 10 30, 7.2 × 10 25, 7.2 × 10 30 7.6 × 10 25
O 7.6 × 10 25, 7.2 × 10 25, 7.2 × 10 30 7 × 10 30
O 7.2 × 10 30 7 × 10 30 7.6 × 10 25 7.2 × 10 25
O 7.6 × 10 25 7.2 × 10 30 7.2 × 10 25 7 × 10 30
The set of numbers arranged in descending order is:
O 7.2 × 10 30, 7 × 10 30, 7.6 × 10 25, 7.2 × 10 25
To determine which set of numbers is arranged in descending order, we need to compare the given numbers and their exponents.
Let's compare the numbers:
0 7 × 10 30
7.2 × 10 25
7.2 × 10 30
7.6 × 10 25
The rule for descending order is that the largest numbers come first. So, we compare the numbers and arrange them in descending order:
7.2 × 10 30 (largest)
7 × 10 30
7.6 × 10 25
7.2 × 10 25 (smallest)
Therefore, the correct answer is:
O 7.2 × 10 30, 7 × 10 30, 7.6 × 10 25, 7.2 × 10 25
