For this case what you must do is add the number of hours to perform the different activities.
We have then:
14 person-hours of labor to break up to driveway and clear away the rubble.
8 person-hours of labor to pour and smooth concrete for the new driveway.
Adding both activities we have
14 + 8 = 22
answer
it takes to break up to driveway, clear away the rubble, pour the concrete, and smooth the concrete about 22 person-hours of labor
Answer:
Step-by-step explanation:
<ABC = x + 45 = 180
x = 135
<ABE = 45
vertical to <CBD is 45
<EBD= 135 due to <ABD is vertical
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
= 18 feet approx
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".
