Suppose that three Civilian Conservation Corps members, Richard, Nancy, and John, had to build a rock wall. They had to move 21 boulders across a field. Seven of the boulders were
large, weighing 25 pounds each. Seven of the boulders were medium-sized, weighing 20
pounds each. Seven of the boulders were small, weighing 15 pounds each. Each worker had
a wheelbarrow. They agreed to share the task equally. Each person carried the same number
of boulders and the same number of pounds. How did they manage to do this?

i hope this is what you were looking for.

see attached graph

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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.
