5. There were 30 students in that class.

6. Drew weighed 245 pounds at the start.

Step-by-step explanation:

5. Since 3 students are absent in which represents 10% of the classroom, multiply the number 3 by 10 to get 30 students which represents the full roster.

6. 20% of his original weight is 49, multiply that number by 5 to get the original weight which is 245 pounds.

5. 3 / 0.1 = 30 students

6. 49 / 0.2 = 245 lbs

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
