<u>Answer:</u>
Ella will need 6 lemons for 4 times the recipe
<u>Explanation:</u>
Given Ella used ¾ of a bag of lemon to make ½ liters of lemonade
Therefore, we can form an equation as:
¾ bag lemons = ½ liter lemonade
According to question,
Ella recipe is for 1 liter of lemonade
Lemons required for ½ liter lemonade = bag
Lemons required for 1 liter lemonade = = 3/2 bags
To make 4 times the recipe, she will require,
She will need 6 lemons for 4 times the recipe
For this case we have by definition, that the sum of the exterior angles of a polygon is equal to 360 degrees, only when considering only one exterior angle for each vertex of the polygon, regardless of the number of sides it possesses. That said we have to:
The external angle of a regular polygon is given by:
Where:
n: It is the number of sides of the polygon
Then, for a nonagon each exterior angle will measure:
Answer:
40 degrees each exterior angle
360 degrees the sum
