if 8 out of every 10 high school students take a math class, how many students in a high school with 700 students are in the math class?

560

Step-by-step explanation:

8 out of 10 is 80%, so then the answer would be 80% of 700, which would be 560

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
