Answer:
250°F
Step-by-step explanation:
Assuming the temperature of the room will not change, first calculate the temperature drop in the first 30 minutes:
350 - 300 = 50
So in the first 30 minutes, the temperature dropped 50°F, to find the temperature of the cooking after an additional 30 minutes (making the total time an hour) simply subtract this value from the temperature:
300 - 50 = 250
Meaning the end temperature will be 250°F.
Hope this helps!
Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
= 
(you add 5 and 9 together because negative + negative is positive)
126/14 = 9
