Answer

I don't like inequalities, but you said please.

This is a toughie for middle school.  I'm going to guess the denominator on the right is really

We note we're dealing with all positive numerators and denominators, because the radical sign on the square root indicates the principal value of the square root which is always positive (or imaginary, in which case inequalities don't apply).  The cube root is of a positive number so will be positive.

Cross multiplying doesn't change the sense of the inequality because the factors are positive.  Of course the square root of 1 is 1.

Rewriting the radicals as fractional exponents,

Let's raise everything to the sixth power to get rid of those fractional exponents.

Everything's a power of 3, so we take the log base 3.  Log is monotonic increasing so the inequality is preserved.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
