At telepower plus, long-distance phone calls to china cost $0.59 for the first minute and $0.25 for each additional minute, plus an additional roaming charge of $2.50. if the total charge of a call to beijing was $11.84, how many minutes did the call last?

Step-by-step explanation:

$0.59 for the first minute

11.84 - 0.59 = 11.25

1 Minute

An additional roaming charge of $2.50

11.25 - 2.50 = 8.75

$0.25 for each additional minute

8.75 / 0.25 = 35

1 + 35 = 36 minutes.

Multiply it back out to check it's right.

2.50 + 0.59 + (35 * 0.25) = 11.84

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
