Answer:
a. 1/27
Step-by-step explanation:
When dividing exponents and the base is the same, we subtract them
x^a/ x^b = x^(a-b)
3^3/3^6
3^(3-6)
3^(-3)
The negative exponent means it is in the denominator
1/3^3
1/27

Answer: 707 km/h
Step-by-step explanation:
let c = speed of current
16.5 + c = speed of sailboat downstream
16.5 - c = speed of sailboat upstream
distance = travel time * speed
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋
2(16.5 + c) = 5(16.5 - c)
33 + 2c = 82.5 - 5c
7c = 49.5
c = 7.07 km/h
