Answer:
months
Step-by-step explanation:
Given that company 
charges 
upfront and 
per month and company B does not charge the upfront fee but charges 
per month.
Let after 
months both the company charges the same amount.
Total charges by the company 
and total charges by the company 
.
Now, from the given condition both the charges are equal, so
Hence, after months both the company charges the same amount.
Answer:
:D
Step-by-step explanation:
For part A, if P is the center of that triangle, then PR and PT have the same length; therefore, triangle RPT is isosceles. For part B, by the definition of an incenter...if P is an incenter, then it is the place where all the angle bisectors meet. Therefore, angles SRP and PRT are congruent, as are angles STP and PTR. Since the vertex angle measures 64, then each of the base angles by the isosceles triangle theorem measure 58. Half of 58 makes the base angles within the smaller triangle measure 29. And if both of those measure 29, by the triangle angle-sum theorem, 180-29-29 = 122 And that's the measure of angle RPT. Eek.
