Answer:

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.

\text{Amount spent on long distance call}=\$15-\$7.74

\text{Amount spent on long distance call}=\$7.26

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.

\text{The number of minutes of Martina's long distance call}=\frac{\$7.26}{\$0.22}

\text{The number of minutes of Martina's long distance call}=33

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

I need an equation for: what number is 70% of 120
kifflom [539]
You'll have to multiply 0.7 by 120.

120*0.7 = n

n is the number that is 70% of 120

120 * 0.7 = 84

Hope this helps :)

Answer: The third one

Step-by-step explanation: We can eliminate the first one right off the bat sinc we see that -4 has two outputs. Next, the graph's equation has no slope (x=3) so the input is all the same. Thirdly, the table shows a relationship between x and y and the numbers don't have a pattern that shows more than one output or input for a number. The fourth option are simply coordinates, it doesn't particularly tell us that all the coordinates are related to each other.
