Question

Here is something to blow your mind. In one slice of "everything" pizza there are 650 Calories (1000 chemistry calories). That equates to 2,700,000 J of energy. How many slices of pizza did you and your 131 other classmates "burn up" in those 50 minutes. Round up to two digits.

Answer 1

Answer:

Number of slices of pizza is 993.

Explanation:

It is given that,  in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :

1 calorie = 4.184 joules

650 calories = 2719.6 joules

Total energy in the pizza, E = 2700000 J

Let there are n number of slices of pizza. It is given by :

$n=\dfrac{2700000}{2719.6}$

n = 992.79

or

n = 993

So, there are 993 slices of pizza. Hence, this is the required solution.
