No because they are different variables. If you pretend to graph... X^8 would be horizontal and Y^3 would be vertical.
Answer:
4.875 billion hours
Step-by-step explanation:
-Let X be the total time spent on taxes and 7.8 billion (80%) is time on paper work.
#We equate and cross multiply to get the total time on taxes:

-let y be the 50% amount of time spent. we equate to find it in actual hours:

Hence, 50% of the time is equivalent to 4.875 billion hours
The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Step-by-step explanation:
Given that,
The kitchen sink can fill in: 6 mins
The sink can drain in: 10 mins
We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,
Lets say, the full tank = 1
Filling rate = 
Drainage rate = 
Hence, the time to fill the tank would be:

(Multiply by LCM)


x = 15
Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
You get a parallelogram and possibly a hexagon. It all depends on the size of the diamond.
