Darnell went to the movies with his friends. the mivie started at 2: 35 anf lasted an 1 hour and 45 minutes .what time did the movie end

We know the movie started at 2:35

The movie lasted 1 hour and 45 minutes, so simply 1:45 (hours:minutes)

Add 2:35 with 1:45 so,

2:35 + 1:45 = 3:80

There can only be 60 minutes maximum, and 60 minutes = 1 hour, so convert the excess amount of 80 minutes to hours (which equals 1 hour and 20 minutes)

Simply add 1 to the hours and the minutes go back to 20 (since we've subtracted 60 from 80)

The movie ended 4:20

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
