You are served dessert at a restaurant. You want to know what % of the calories in the dessert are from fat. The menu states tha
jasenka [17]

Answer:

39.82 %

Explanation:

Proteins and carbohydrates provide 4 calories per gram. On the other hand, fats provide 9 calories.

We can first calculate the calories of protein + carbohydrates:

       (30g + 4g) x 4 = 136 calories

And we must calculate the calories provided by fat:

        10g x 9 = 90 calories

Now to get the percentage we must see how many calories the dessert has in total:

          136 + 90 = 226 cal

This represents 100% of calories. And now we need to find out how much 90 calories are from the total.

           226 cal -----> 100%

             90 cal ------> X

       (90 x 100) / 226 = 39.82 %

Why do so many (~30%) gorilla babies die within the first few months of their lives?
katrin2010 [14]

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

What is inherited disease?

Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.

Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.

Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.
