Which set of numbers is arranged in descending order? (1 point)
7.6 * 10 ^ - 25, 7.2 * 10 ^ - 30, 7.2 * 10 ^ - 25, 7 * 10 ^ - 30;
7.2 * 10 ^ - 30, 7 * 10 ^ - 30, 7.6 * 10 ^ - 25, 7.2 * 10 ^ - 25;
7.6 * 10 ^ - 25, 7.2 * 10 ^ - 25, 7.2 * 10 ^ - 30, 7 * 10 ^ - 30;
7 * 10 ^ - 30, 7.2 * 10 ^ - 25, 7.2 * 10 ^ - 30, 7.6 * 10 ^ - 25
The set of numbers arranged in descending order is:
7.6 * 10 ^ -25, 7.2 * 10 ^ -25, 7.2 * 10 ^ -30, 7 * 10 ^ -30.
To arrange the numbers in descending order, we need to compare their values.
Looking at the numbers provided, the first part before the multiplication symbol (7.6, 7.2, 7.2, 7) is the same for all of them. In this case, the smaller numerical value will come first.
The second part after the multiplication symbol (^) represents the exponent. The higher the exponent, the smaller the number.
Comparing the exponents, we have -25, -30, -25, -30. In descending order, the exponents will be -25, -25, -30, -30.
Now, let's arrange the numbers based on the exponents:
7.6 * 10 ^ -25
7.2 * 10 ^ -25
7.2 * 10 ^ -30
7 * 10 ^ -30
Therefore, the numbers arranged in descending order are:
7.6 * 10 ^ -25, 7.2 * 10 ^ -25, 7.2 * 10 ^ -30, 7 * 10 ^ -30.
The correct option is:
7.6 * 10 ^ -25, 7.2 * 10 ^ -25, 7.2 * 10 ^ -30, 7 * 10 ^ -30.
The set of numbers arranged in descending order is:
7.6 * 10^-25, 7.2 * 10^-25, 7.2 * 10^-30, 7 * 10^-30.
