Question

2 a. the emperor penguin keeps its egg warm through the winter by holding it on top of its feet and under a brood pouch. the temperature inside the pouch is 36°c. if this is 78° warmer than the outside temperature, what is the outside temperature?

Explanation:

Step1: Define the variable

Let \( t \) be the outside temperature (in \(^{\circ}\text{C}\)).

Step2: Set up the equation

The pouch temperature (\( 36^{\circ}\text{C} \)) is \( 78^{\circ}\text{C} \) warmer than the outside temperature. So, the equation is \( t + 78 = 36 \).

Step3: Solve for \( t \)

Subtract \( 78 \) from both sides of the equation: \( t = 36 - 78 \).
Calculate \( 36 - 78 = -42 \).

Answer:

The outside temperature is \(-42^{\circ}\text{C}\)
