Answer:

Step-by-step explanation:
The relevant properties are ...
(a^b)^c = a^(bc)
(a^b)/(a^c) = a^(b-c)
So, the expression simplifies to ...

As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.

The answer should be a, 45
Answer: it should be 252 in.
Step-by-step explanation:
Answer:
half of 20 is 10
10 is your new radius so
10^2 = 100
100 x 3.14 = 314
Now we multiply by the height:
314 x 11 = 3,454 cm^3
