Answer:

Step-by-step explanation:

\frac{27^{1/3b}}{9^{1/2a}}

We know that 27^(2/3) = 9. So:

= \frac{27^{1/3b}}{27^{1/3a}}

note: 9^(1/2a) = 9^((2/3)(1/2)(a)) = 27^(1/3a)

= 27^{1/3b-1/3a}=27^{1/3(b-a)} = 27^{1/3(2))} = 9

9 is the answer

A retiree invests $9,000 in a savings plan that pays 5% per year. What will the account balance be at the end of the first year
densk [106]
Using the formula I=Pxrxt
P is the principal amount, $9000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 1....year(s) time periods.
So, t is 1....year time periods.
To find the simple interest, we multiply 9000 × 0.05 × 1 to get that:

The interest is: $450.00
So the balance will be $9450.00 at the end of the first year.

What would be the dimensions of the poster at fraction 1 over 4 times its current size?
Butoxors [25]
The answer is Length = 6cm, width = 9cm.
This is because to find 1/4 multiplied by the dimensions, you need to divide by 4. 36 ÷ 4 = 9, and 24 ÷ 4 = 6. I hope this helps!
