The table shows the change in temperature each hour for four hours. Find the total change C in temperature.

Change in Temperature
6 A.M. - 7 A.M. −3°F
7 A.M. - 8 A.M. −2°F
8 A.M. - 9 A.M. +4°F
9 A.M. - 10 A.M. +6°F

Respuesta :

9 degrees

6 degrees plus 3 is 9

Answer:

5°F

Step-by-step explanation:

From the given information it is clear that

Change in temperature for time interval 6 A.M. - 7 A.M = −3°F

Change in temperature for time interval 7 A.M. - 8 A.M = −2°F

Change in temperature for time interval 8 A.M. - 9 A.M = 4°F

Change in temperature for time interval 9 A.M. - 10 A.M = 6°F

The total change C in temperature is

[tex]C=(-3^{\circ} F)+(-2^{\circ} F)+(4^{\circ} F)+(6^{\circ} F)[/tex]

[tex]C=(-3-2+4+6)^{\circ} F[/tex]

[tex]C=5^{\circ} F[/tex]

Therefore, the total change C in temperature is 5°F.
