9.4 × 10-4 = 0.00094 0.0094 94,000 940,000

0.00094

Step-by-step explanation:

Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:

Use a positive exponent for large numbers greater than 1.Use a negative exponent for small numbers less than 1.Always write the first number as a value between 0 and 9.

9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is -4, this means 0.00094 is the solution.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
