Answer:
5^15
Step-by-step explanation:
A power to a power you multiply
so you would get (5^27)/(5^12)
Division, you subtract the exponents
At first I assumed you were asking for 3 different ratios equivalent to 1/10, which could be 2/20, 10/100, or 5/50. But it seems you are asking for ratios equivalent to 1/10 gallons to second.
For this, you could change both the 'gallons' and the 'seconds' to get different unit with the same ratio.
1/10 gallon/second * 60 seconds / 1 minute = 6 gallons/minute
1/10 gallon/second * 1 gallon / 4 quarts = 1/40 quarts/second
combining these two conversions we can do
1/10 gallon/second * 60 second / 1 minute * 1 gallon / 4 quarts = 3/2
Final answer:
1/10 gallons/second = 6 gallons/minute = 1/40 quarts/second = 3/2 quarts/minute

Answer:
Option D) B and C
Step-by-step explanation:
we know that
To find out the percentage of high school teachers that have a second job, divide the number of teachers that have a second job by the total number of teachers
<em>Survey A</em>

Convert to percentage

<em>Survey B</em>

Convert to percentage

<em>Survey C</em>

Convert to percentage

<em>Survey D</em>

Convert to percentage

Compare the percentages
Surveys B and C have the same percentage
therefore
Surveys B and C show proportional results, because the ratio of the number of teachers that have a second job by the total number of teachers is equal (this number is the constant of proportionality k in a proportional relationship between two variables)
