Frankies misic class begins at 9: 40 a. m. the class is 45 minutes long. when does frankies class end?

10:25

Step-by-step explanation:

Because there are 60 minutes in an hour, if you add 20 minutes to 9:40, it will be 10:00. Then, you still have 25 minutes left from your 45 minute class. This ends at 10:25.

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

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
