Martina purchased a prepaid phone card for $ 15 . long distance calls cost 22 cents a minute using this card. martina used her card only once to make a long distance call. if the remaining credit on her card is $ 7.74 , how many minutes did her call last? minutes

33 minutes.

Step-by-step explanation:

We have been given that Martina purchased a prepaid phone card for $15 . Long distance calls cost 22 cents a minute using this card. Martina used her card only once to make a long distance call and the remaining credit on her card is $7.74.

Let us find the amount spent on the long spent call by subtracting $7.74 from $15.

Therefore, Martina spent $7.26 on long distance call.

As each minute of long distance call costs 22 cents ($0.22), so to find the number of minutes of Martina's call we will divide 7.26 by 0.22.

Therefore, Martina's long distance call last for 33 minutes.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
