At a fast-food restaurant, a hamburger contains 37 g of carbohydrate, 19 g of fat, and 24 g of protein. What is the total energy content, in kcal? Report your answer with 2 significant figures, do not use scientific notation.

[a] kcals

37 g of carbohydrate, 19 g of fat, and 24 g of protein.

Carbs have 4 kcal/g
Fat has 9 kcal/g
Protein has 4 kcal/g
(37 x 4) + (19 x 9) + (24 x 4) = ? kcal

Why was the math book sad?

Because it had too many problems, just like me trying to calculate the answer to your question! Let me whip out my calculator and crunch some numbers for you.

To calculate the total energy content in kcals, we need to know the energy values per gram of each macronutrient. Carbohydrates and protein both have 4 kcal per gram, while fat has 9 kcal per gram.

So, let's do the math:

Carbohydrates: 37 g * 4 kcal/g = 148 kcal
Fat: 19 g * 9 kcal/g = 171 kcal
Protein: 24 g * 4 kcal/g = 96 kcal

Now let's add them all up:
148 kcal + 171 kcal + 96 kcal = 415 kcal

Therefore, the total energy content in the hamburger is approximately 415 kcal.

To calculate the total energy content in kcal, you need to know the energy value per gram for each macronutrient. The energy values are as follows:

- Carbohydrate: 4 kcal/g
- Fat: 9 kcal/g
- Protein: 4 kcal/g

To find the total energy content, you will multiply the grams of each macronutrient by their respective energy values and then sum them together.

For carbohydrates:
37 g of carbohydrate * 4 kcal/g = 148 kcal

For fat:
19 g of fat * 9 kcal/g = 171 kcal

For protein:
24 g of protein * 4 kcal/g = 96 kcal

Now, add up the energy values for each macronutrient:
148 kcal + 171 kcal + 96 kcal = 415 kcal

Therefore, the total energy content of the hamburger is 415 kcals.

To calculate the total energy content of the hamburger, we need to use the energy values for each macronutrient. The energy values per gram are as follows:

- Carbohydrates: 4 kcal/g
- Fat: 9 kcal/g
- Protein: 4 kcal/g

To find the energy content from each macronutrient, we multiply the grams by their respective energy values:

Carbohydrates: 37 g * 4 kcal/g = 148 kcal
Fat: 19 g * 9 kcal/g = 171 kcal
Protein: 24 g * 4 kcal/g = 96 kcal

Finally, to find the total energy content of the hamburger, we add up the energy from each macronutrient:

Total energy content = Carbohydrates + Fat + Protein
Total energy content = 148 kcal + 171 kcal + 96 kcal = 415 kcal

Therefore, the total energy content of the hamburger is 415 kcal.
