Answer:

  0.15 for each message

Step-by-step explanation:

The charge per message can be found by dividing the charge by the number of messages. Using the first line of the table, we get ...

  charge per message = (total charge)/(number of messages) = $38.40/256

  charge per message = $0.15

Alyssa is charged 0.15 for each text message.

_____

We can check other lines of the table to see if charges are really proportional:

  $26.55/177 = $0.15

  $31.35/209 = $0.15

Papa john is 50 years old. His age is 2 years more than 3 times the age of Jimmy John. How old is Jimmy?
mojhsa [17]

Answer:

<h2>Jimmy is 16 old.</h2>

Step-by-step explanation:

J - the age of Jimmy John

50 - the age of Papa John

3J + 2 - the age of Papa John

The euaqtion:

3J + 2 = 50             <em>subtract 2 from both sides</em>

3J + 2 - 2 = 50 - 2

3J = 48          <em>divide both sides by 3</em>

3J/3 = 48/3

J = 16

How do I do numbers 12 to 14?
NARA [144]

Answer:

  12.  1 second, 35 ft; 2 seconds, 32 ft

  13.  (t, y) = (1.4 seconds, 37.6 feet)

  14.  37.6 ft; the vertex is the highest point

Step-by-step explanation:

12. You have properly answered question 12.

After 1 second, the height is 35 feet; after 2 seconds, it is 32 feet.

__

13. My method of choice is to plot the graph on a graphing calculator and let it show me the coordinates of the vertex when I highlight that point. (See attached.) The vertex is ...

  (t, y) = (1.4, 37.6)

__

14. The graph is a graph of height when the object is launched with a vertical velocity of 45 ft/s. So, the maximum of the graph will correspond to the maximum height of the object. The vertex is that maximum point, and its y-coordinate is that maximum height.

The maximum height is 37.6 feet.
