Answer:

c. $\dfrac{2}{3}$

Step-by-step explanation:

Let the common ratio be r.

$a_2 = \dfrac{2}{5}$

$a_3 = \dfrac{2}{5}r$

$a_4 = \dfrac{2}{5}r^2$

$a_5 = \dfrac{2}{5}r^3$

We are told that $a_5 = \dfrac{16}{135}$ .

$\dfrac{2}{5}r^3 = \dfrac{16}{135}$

$\dfrac{5}{2} \times \dfrac{2}{5}r^3 = \dfrac{5}{2} \times \dfrac{16}{135}$

$r^3 = \dfrac{8}{27}$

$r = \sqrt[3]{\dfrac{8}{27}}$

$r = \dfrac{2}{3}$

Answer: c. $\dfrac{2}{3}$

At the beginning of the week the balance in your checkbook was $298.72. During the week you made a deposit of $425.69. You also

lyudmila [28]

$298.72+ $425.69- $29.72- $135.47- $208.28- $5.00= $345.94.

There is $345.94 in the account at the end of the week.

Remember that when you make a deposit, you add money to your account and when you write checks, it means you take away the money from your account.

Hope this helps~
