A) 7.4
B) 0.74
C) 74
D) 0.074

Answer 1

The area of Jose's new property in standard notation is 0.74 square miles.

Step-by-step explanation:

Jose's property area displayed as 7.4E - 1 in scientific notation on a calculator translates to 0.74 square miles in standard notation. In scientific notation, the "E" stands for "exponent" and represents "times ten raised to the power of." The negative sign after the E indicates that the decimal point is to be moved to the left. Therefore, 7.4E - 1 is equivalent to 7.4 × 10-1, which means the decimal point is moved one place to the left, resulting in 0.74.
