Answer: 15
Step-by-step explanation:
Add 5 to 40, you get 45, then divide 45 by 3, you get a result of 15
Answer:
The approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
Step-by-step explanation:
The formula for D, the difference in temperature between the pan and the room after t minutes is:
![D = 324\cdot e^{-0.05t}](https://tex.z-dn.net/?f=D%20%3D%20324%5Ccdot%20e%5E%7B-0.05t%7D)
Compute the approximate difference in temperature between the pan and the room after 9 minutes as follows:
![D = 324\cdot e^{-0.05t}](https://tex.z-dn.net/?f=D%20%3D%20324%5Ccdot%20e%5E%7B-0.05t%7D)
![=324\times e^{-0.05\times 9}\\\\=206.59](https://tex.z-dn.net/?f=%3D324%5Ctimes%20e%5E%7B-0.05%5Ctimes%209%7D%5C%5C%5C%5C%3D206.59)
Then the approximate temperature of the pan after it has been away from the heat for 9 minutes is:
D = P - R
206.59 = P - 69
P = 206.59 + 69
P = 275.59°F
Thus, the approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.
Length squared + width squared = Diagonal squared
Length squared = 900cm
Width squared = 256cm
total = 1156
Therefore Diagonal squared = 1156
Diagonal = 34cm
Answer:
X= 65
Step-by-step explanation:
180°-50°=130 (Angles on a straight line)
2x=130 ( Corrresponding Angle)
X= 130÷ 2
= 65
Hope this helps.
