Answer:

See below

Step-by-step explanation:

a.  Since they tell you the amount of water increases 1/4 gallon in 2/5 minutes,  you can also see that you'd have 2/4 gallons in 4/5 minutes.  Then 3/4 gallons in 6/5 minutes; 4/4 or 1 gallon in 8/5 minutes.  Finally you can go one more step and see that you would have 5/4 gallons or 1 1/4 gallons in 10/5 minutes.

10/5 minutes is equal to 2 minutes.  so if you divide the gallons by 2 you'll know how many gallons you'd have in 1 minute.  5/4 divided by 2 is equal to 5/8 gallons.

Another way you can look at this is if you have 1/4 gallon in 2/5 of a minute, then you would only have half of the 1/4 gallon in 1/5 of a minute.  Half of 1/4 gallon is equal to 1/8 of a gallon.  So if you are getting 1/8 gallon in 1/5 of a minute, you can multiply them both by 5 to get your answer in gallons/minute.

5 times 1/8 is 5/8 and 5 times 1/5 minutes is 5/5 minutes or 1 minute.

So you get the same answer 5/8 gallons/minute

b.  Above you calculated how many gallons you will get in 1 minute.  So to figure out how much you will get in 5 minutes, you'd multiply 5/8 by 5.  This gives you 25/8 or 3 1/8 gallons.  If you started with 6 gallons in the tub, now you just add those two numbers together to get 9 1/8 gallons.

c.  Again we can look at the sink the same as the bath tub.  Keep adding the gallons and minutes until you can get the minutes fraction equal to a whole number.  3/5 gallon in 4/5 minutes double to be 6/5 gallons in 8/5 minute, 9/5 gallons in 12/5 minutes, 12/5 gallons in 16/5 minutes and finally 15/5 gallons in 20/5 minutes.  20/5 minutes is the same as 4 minutes in whole numbers.

So if you divide both the gallons and minutes by 4, you'll get how many gallons you're getting in 1 minute.  15/5 gallons divided by 4 is 15/20 gallons.  This can be reduced down to 3/4 gallons.  When you divide 4 minutes by 4, you get 1 minute.  So the sink is getting 3/4 gallon/minute.

Which is getting more water per minute?  3/4 gallons/minute is more than 5/8 gallons/minute so the sink is filling more rapidly.

Answer:

  rules of exponents apply

Step-by-step explanation:

The applicable rules of exponents are ...

  a^-b = 1/a^b

  (a^b)(a^c) = a^(b+c)

__

Applying those rules to the given equation, you get ...

  \left(\dfrac{1}{5}\right)^4\cdot\left(\dfrac{1}{5}\right)^2=5^{-6}\\\\ \left(\dfrac{1}{5^4}\right)\cdot\left(\dfrac{1}{5^2}\right)=5^{-6}\\\\ (5^{-4})(5^{-2})=5^{-6}\\\\5^{-4-2}=5^{-6}\\\\5^{-6}=5^{-6}
