727.29 - 248.50 = 478.79

500-478.79 = 21.21

Answer:

She needs to deposit at least $21.21 in her account to avoid a fee.

Step-by-step explanation:

Consider the provided information.

Tony has $727.29 in his checking account and he wrote a check for $248.50 today.

Let x be the amount that she needs to deposit.

He must maintain a $500 balance to avoid a fee. That means the balance can be greater than or equal to $500.

The inequality used for greater than or equal is ≥

As he wrote a check which indicates the deduction from account so use a negative sign and to deposit use a positive sign,

Thus the required inequality is:

727.29-248.50+x\geq 500

Now add the like terms:

727.29-248.50+x\geq 500

478.79+x\geq 500

Subtract 478.79 from both sides.

478.79-478.79+x\geq 500-478.79

x\geq 21.21

Hence, she needs to deposit at least $21.21 in her account to avoid a fee.

Please help me with this problem <br> Evaluate (-½·3)³
-Dominant- [34]

Answer: -27/8

Step-by-step explanation:

\left(-\frac{1}{2}\cdot \:3\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=-a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:odd}

\left(-\frac{1}{2}\cdot \:3\right)^3=-\left(\frac{1}{2}\cdot \:3\right)^3

=-\left(\frac{1}{2}\cdot \:3\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n

\left(\frac{1}{2}\cdot \:3\right)^3=\left(\frac{1}{2}\right)^3\cdot \:3^3

=-\left(\frac{1}{2}\right)^3\cdot \:3^3

=-\frac{1}{8}\cdot \:3^3

=-\frac{1}{8}\cdot \:27

=-\frac{27}{8}
