Answer:
After 49 months the total cost of the two systems will be equal.
Step-by-step explanation:
To Find: We need to find the number of months will the total cost of the two systems be equal
Solution:
For Satellite receiver:
Satellite receiver cost = $298.90
Monthly charge = $68.70
Let the Number of months be denoted by 'x'.
Now we can say that;
Total cost using Satellite receiver is equal to sum of Satellite receiver cost and Monthly charge multiplied by number of months.
framing in equation form we get;
Total cost using Satellite receiver =
For Using Cable:
Monthly charge = $74.80
So we can say that;
Total cost using cable is equal to Monthly charge multiplied by number of months.
framing in equation form we get;
Total cost using cable =
Now to find the number of months when both the cost will be the same so we will make both the equation equal we get;
Combining the like terms we get;
Dividing both side by 6.1 we get;
Hence After 49 months the total cost of the two systems will be equal.
Answer:
Missing side is 9 cm
Step-by-step explanation:
a^2 + b^2 = c^3
(12)^2 + b^2 = (15)^2
144 + b^2 = 225
b^2 = 81
=
b = 9 cm
