If 17 people voted for Jason as Vice President and 8 people voted for Karen as Vice President, what is the percent of votes for
german

Answer:

Jason's percentage is 68%

We end up getting 32% for Karen.

Step-by-step explanation:

First, we need to get the total amount of votes.

17 + 8 = 25.

25 is the total amount of votes. If Jason had got 17/25 votes we can do 2 steps to get his percentage. We can simply divide 17 by 25, or we can multiply the numerator and denominator by 4. We end up getting 68/100.

So Jason's percentage is 68%

Now we do Karen. 8/25 people voted for her, so we can again, do two ways to solve this. One way is dividing 8 by 25, another way is to multiply both the numerator and denominator by 4 because we want it out of 100.

We end up getting 32% for Karen.

The measure of an interor angle of a regular polygon is given. Find the number of sides in the polygon.
EleoNora [17]

Let side be n

#1

\\ \sf\longmapsto 120n=(n-2)180

\\ \sf\longmapsto 120n=180n-360

\\ \sf\longmapsto -60n=-360

\\ \sf\longmapsto n=6

#2

\\ \sf\longmapsto 160n=(n-2)180

\\ \sf\longmapsto 160n=180n-240

\\ \sf\longmapsto -20n=-240

\\ \sf\longmapsto n=12

#3

\\ \sf\longmapsto 144n=(n-2)180

\\ \sf\longmapsto 144n=180n-360

\\ \sf\longmapsto -36n=-360

\\ \sf\longmapsto n=10
