In a poll, 9 out of 25 students in lydia's science class say they will vote for her for class president
in lydia's history class, 4 out of 16 students say they will vote for her. which is greater, the
percent of students who will vote for lydia in her science class or in her history class?

answer:

the percentage of students in her science class.

step-by-step explanation:

if you turn 9/25 into a decimal you get 0.36. turn that into a percent and you get 36%.

if you turn 4/16 into a decimal you get 0.25. turn that into a percent and you get 25%.

36% is greater than 25% so that's how you get the answer. hope this !

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.
