Answer:
It will take 17.5 minutes to reach 50 degrees F.
Step-by-step explanation:
Current temperature = -13 degrees F
With the engine on, the temperature goes up by 3.6°F per minute.
Let us assume that it takes x minutes to reach 50 degrees F.
So, the time taken will be =
=> 
=> 
x = 17.5 minutes
The expression that tells how much the temperature needs to change from -13°F to 50°F is :
It will take 17.5 minutes to reach 50 degrees F.

Answer:
Step-by-step explanation:
Answer:
Solution:
(i) 135°
No of sides = n
Each interior angle = 135°
(2n -4) x 90° /n = 135°
180n - 360° = 135n
180n - 135 = 360°
n = 8
Which is not a whole number
Hence, it is possible to have a regular polygon whose interiro angle is 135° .
(ii) 155°
No of sides = n
