![8 < \sqrt[3]{a} < 9](https://tex.z-dn.net/?f=8%20%3C%20%5Csqrt%5B3%5D%7Ba%7D%20%3C%209)

So, a can be any number between (512, 729).
∴ answer is (A) 679
The total bill was inclusive of the one-time payment of $50 and an additional payment of $25 per month. The only unknown variable here is the amount of months you've had the phone. This can be solved by isolating the unknown variable, like so:
Let: x = number of months
Total bill = one-time payment + monthly payment * number of months
$375 = $50 + $25x
375 - 50 = 25x
325 = 25x
325/25 = 25x/25
x = 13
Therefore, you've had the phone for 13 months.
Answer:
Step-by-step explanation: L= length w= width p= perimeter
L=3W p=55CM
P. of rectangle= 2(l+w)=55cm
L+w= 55/2= 27.5 cm
3w+w=27.5cm
4w=27.5cm
w=27.5/4=6.875cm w=6.875cm L= 3w=6.875*3=20.625cm
