Riding on a school bus are 20 students in 9th grade, 10 in 10th grade, 9 in 11th grade, and 7 in 12th grade. Approximately what percentage of the students on the bus are in 9th grade?

Wouldn't it be 20/46?

Since 20+10+9+7= 46 which is the total of students.
And since you are trying to find what percentage of them are 9th graders it's 20.
So 20/46= 0.43 which is 43%
So the answer is 43% of the students on the buss are 9th graders.

20/45 = ?

43.47826087 actually mate

20+10+9+7=46

20/46= .43
=43%

x-6 is greater than -6 and x over 6 is less than equal to 1 what would it equal

20+10+9+7=46

There are 20 students in 9th Grade.
20/46=0.43478261
The percentage of students in the ninth grade riding the bus are 43%.

solve(sin(pi/2 -(20/a)*((1-(20/a)^2)^.5)))
