On a math test, 60%of students use a pencil, half of the remaining students used a red pen if 6 students use a red pen, how many students are in the class

30 people are in the class

Hi!

If 60% of the students used a pencil, then the remaining percentage of the class is 40%, as 60% + 40% = 100%. Since half of that remaining percentage, or half of 40%, used a red pen, then that means 20% used a red pen.

Since 6 students used a red pen, and that is 20%, that means 6 is 20% of the total students in the class.

To get 100%, just multiply both by 5, and you get 30 for 100% of the students.

Therefore, there are 30 students in the class.

Hope this helped!

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
