Answer:
15years
Step-by-step explanation:
6000×10×t÷100=9000
600t=9000
t=9000÷600
t=15years

Answer:
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.
