78.00 = 59.99+0.10x
10.01=0.10x
x= 180.1 so she can send 180 texts plus the 100 free ones for a total of 280 texts
double check: 180 x 0.10 = 18.00 + 59.99 = 77.99
378 feet
Its to long to explain but thats the answer
Answer:

Step-by-step explanation:
6 weeks is 42 days.
6 days/42 days = 1/7
Answer:
7361.56 yards
Step-by-step explanation:
Height of the tower = 906 yards
Mauricio's height = 2 yards
Angle of elevation = 
Let the distance between Mauricio and the base of the tower be represented by x.
The difference between the height of tower and Mauricio's height = 906 - 2
= 904 yards
So that applying the appropriate trigonometric function, we have;
Tan θ = 
Tan
= 
0.1228 = 
x = 
= 7361.5635
x = 7361.56 yards
The distance between Mauricio and the base of the tower is 7361.56 yards.
