Aserving of a breakfast cereal contains 3 g of protien, 18 g of carbohydrats, and 6 g of fat. what is the calorie content of a serving of thi cereal if the average number of calories for fat is 9.1 calories/g. for carbohydrates is 4.1 calories/g, and for protien is 4.1 calories/g?

The calorie content of a serving of this cereal is 140.7 cal.

Explanation:

We need to multiply the amount of calories per the amount of each nutrient.

Proteins: 3 g and 4.1 cal/g ∴ 3 x 4.1 = 12.3 cal

Carbohydrates: 18 g and 4.1 cal/g ∴ 18 x 4.1 = 73.8 cal

Fats: 6 g and 9.1 cal/g ∴ 6 x 9.1 = 54.6 cal

Now we just need to add the amounts:

Total calorie content = 12.3 + 73.8 + 54.6 = 140.7 cal

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

if you mean hydrogen and oxygen then water is the product
