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.

Answer:

  A-  Triangle 2: {8, 15, 17}

Step-by-step explanation:

You may recognize that the triple of choice A is a Pythagorean triple, so can be the side lengths of a right triangle.

Checking the numbers can be done nicely by a graphing calculator or spreadsheet to help avoid the tedium of doing it "by hand".

The basic idea is that the triangle will be a right triangle if the sum of the squares of the shorter sides is the square of the longer side.
