The outside temperature at midnight today in polina’s hometown was 18f. the temperature increases by 1.2f each hour over the next 15 hours. polina’s school does not send students outside for recess if the outside temperature is 32f or lower. recess at her school always starts on the half hour or hour. which statement is true about recess at polina’s school?

a. only students who have recess at 11: 00 a. m. or later may go outside.

b. only students who have recess at 11: 30 a. m. or later may go outside.

c. only students who have recess at 12: 00 p. m. or later may go outside.

d. only students who have recess at 12: 30 p. m. or later may go outside.

D.

Step-by-step explanation:

I did: 18+(1.2 x 15). I got 36. So i know that in 15 hrs. It will be 36 degrees. But recess will most likely be over by then. So i switched out the number 15 for each time. In 11 hrs (so it would be 11am) them temperature would be 31.2. So its would be too cold. In 11.5 hrs (11:30am) it would be 31.8. Still too cold. I tried 12 hrs (12pm), I got 32.4, which is still too cold. So D is the correct answer becuase when I tried 12.5 hrs. (12:30pm) it would have been 33 degrees outside.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
