Answer: $200
Step-by-step explanation:
Given: In 1 year ,
Linda's parents spend $2400 on cable and internet service.
If they spend the same amount each month, Monthly payment = 
![=\dfrac{\$2400}{12}\ \ \ [\text{Number of months in a year}=12]\\\\=\$200](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5C%242400%7D%7B12%7D%5C%20%5C%20%5C%20%5B%5Ctext%7BNumber%20of%20months%20in%20a%20year%7D%3D12%5D%5C%5C%5C%5C%3D%5C%24200)
Hence, the resulting monthly change in the family's income = $200
Answer:
sum of the interior angles x and y gives the exterior angle z
(4n-18)°+(n+8)°=(133-6n)°
4n°-18°+n°+8°=133°-6n°
4n°+n°-18°+8°=133°-6n°
5n°-10°=133°-6n°
5n°+6n°=133°+10°
11n°=143°
11°n/11°=143°/11°
n=13
exterior angle=133-6×13
=133-78
=55

Answer:
81 pi cm^2
or approximately 254.34 cm^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (9)^2
A = 81 pi
Using 3.14 as an approximation for pi
A = 81 (3.14)
A =254.34 cm^2
