Each student in a pottery class is responsible for cleaning the area around his or her workspace at the end of the lesson. each student's area is approximately 4 and 1/2ft. there are 13 students in the class. assuming that each student cleans his or her area, how many square feet in total is cleaned? use addition to rewrite the fraction, and multiply using the distributive property.

your answer is 58 sq. ft.

Step-by-step explanation:

4 1/2 × 13

Covert the mixed number into an improper fraction

4 1/2 = 9/2

Then make 13 into a fraction

13/1

Now multiply the fractions

9 × 13  =  117

2 × 1    =    2

Next change the improper fraction into a mixed number

58 1/2

Next change it into a decimal

58.5

Lastly round it and we have the answer

58  

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
