ANSWER

x=100,y=10

EXPLANATION

The given logarithmic equations are;

$log_{10}( {x}^{2} {y}^{3} ) = 7$

This implies that,

${x}^{2} {y}^{3} = {10}^{7} ...(1)$

and

$log_{10}( \frac{x}{y} ) = 1$

This implies that,

$\frac{x}{y} = {10}^{1}$

$x = 10y...(2)$

Put equation (2) into equation (1)

${(10y)}^{2} {y}^{3} = {10}^{7}$

$10 ^{2} y^{2} {y}^{3} = {10}^{7}$

${y}^{5} = {10}^{5}$

Hence y=10.

This implies

$x = 10(10) = 100$

Did I get this right plz be honest if i fail this i will fail this class

anyanavicka [17]

Step-by-step explanation:

Part A

A) The denominator is 665, so this is a terminating decimal.

B) 11/99 = 1/9 = 0.1111...

C) 256/999 = 0.256256256...

D) 25/909 = 275/9999 = 0.027502750275...

B has 1 repeating digit, C has 3 repeating digits, and D has 4 repeating digits. So the correct answer is C.

Part B

A decimal that can be written as a ratio of integers is a rational number.
