3/4 of the students in a classroom are girls. if there are ten boys in the class, how many total students are there?

40 students total

Step-by-step explanation:

Let s represent the total number of students.  Then (3/4)s are girls and (1/4)s are boys.  Using the info on boys, (1/4)s = 10.  Thus, s = 40 (students).

Check:  Is (1/4)(40) = 10?  Yes.

             Is (3/4)(40) = 30?  Yes

             Is 10+30 = 40 (students)?  Yes

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.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
