Mr. henry expected 10 of the students in his drama class to attend the school play. instead,15 students in his class attended. what percentage more students attended the play than was expected?

50%

Step-by-step explanation: The correct way to calculate what percentage more attended the play is to first subtract the expected number from the actual number. 15 - 10 = 5 more attended than was expected. Next, you need to divide the 5 additional people by the 10 that were originally expected. 5 divided by 10 = 50%

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
