If you do the square root of 16, you get 4 (4*4=16), so this is rational
If you do the square root of 9, you get 3 (3*3=9), so this is rational
If you do the square root of 49, you get 7 (7*7=49), so this is rational
If you do the square root of 2, you get 1.4142....., so this is irrational, since it keeps on repeating
So your answer is B. sq rt 2

Hope this helps!

Find the accumulated value of an investment of 12,000 at 8 % compounded semiannually for 11 years
AleksAgata [21]
The "compound amount" formula is A = P(1+r/n)^(nt),
where P=original investment, r=interest rate as a decimal fraction; n=number of compounding periods, and t=number of years.

Then A = $12000 * (1+0.08/2)^(2*11) 
             = $12000(1.04)^(22)  =  $28,439.03  (answer)

Joelle would like to tip her hairdresser 20%. If her haircut was $38.00, which expression should she use to find the tip amount?

I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
