100÷11=9.09090909
converting it it will be 9.1 miles per hour
Y= 26 & x=35 hope I did it on time!
Answer is 5^12 which is choice A (assuming you meant to put the ^ symbol)
The bases are the same (both are 5), so you add the exponents: 4+8 = 12. The base stays the same the entire time.
So, 5^4*5^8 = 5^(4+8) = 5^12
