Answer:
D
Step-by-step explanation:
Answer: 60 degrees
Step-by-step explanation: triangles are come to 180 if you add all angles correctly. therefore if you do 180-90-30, you'll get 60.
Answer:
16
Step-by-step explanation:
Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
Answer:
B
