the environmental club is holding round two of the clean-up competition. in this round, two-person teams are assigned to areas of land that are scattered with litter. the winner is the team that cleans up its area in the fastest time possible.

team 1: tammy could clean one-half of her area in one hour when she worked alone. her teammate, melissa, could clean one-third of her area in one hour when she worked alone.

team 2: santay could clean one-quarter of his area in an hour when he worked alone. leticia could clean four-fifths of her area in an hour when she worked alone.

find the rate that team one cleaned together (as in time)

find the rate that team two cleaned together

which team was the fastest

explain how you solved.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

1. sometimes

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
