Answer: C: 3 X 10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left decimal. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal. 2.69 (line over .69), therefore, round you get 3. = 3 x 10^4

Step-by-step explanation:

10-4.5=5.5

To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8).
