Here are 5 classes in your grade level. Each class is 6/7 full today. If a full class has 28 students, how many students in your grade are at school today? students *

A minimum of 24 students if all the students share a class with you. Not enough info to decide the largest size of grade.

Step-by-step explanation:

120

Step-by-step explanation:

28 students normally

28(6/7) = 40 today in one class

40*5 = 120 between all 5 classes

i believe the answer is the polygon, heptagon.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
