Answer:
The sum of all internal angles of this polygon is:
Step-by-step explanation:
Recall that the formula for the number of diagonals of a polygon with n-sides is given by the formula:
and since Lucero noticed that the number of digonals was 7 more that the number of sides, then, these two quantities (n + 7) and the number of diagonals must be equal. we can set an equation stating such, and solve for "n" (number of sides of the polygon):
therefore n = 7 or n = -2
The only answer with meaning is the first one (7 sides), since a polygon must have a positive number of sides.
Now that we know the number of sides of the polygon, we can find what the sum of its internal angles should give, based on the equation;
Addition of internal angles of a polygon is =
Which in our case renders:
Answer:
20 cups of punch
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If Elise adds 5 percent of each of the other ingredients
then
the new percentages are
Ginger Ale=40%+5%=45%
Orange Juice=25%+5%=30%
Pineapple Juice=20%+5%=25%
Sorbet=0%
Find out how many cups of punch will she have if she uses 6 cups of orange juice, using proportion
Let
x ----> the total cups of punch
