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:
sorry but what we have to do in this question
Answer:
Step-by-step explanation:
Given:
Given point P(6, 6)
The equation of the line.
We need to find the equation of the line perpendicular to the given line that contains P
Solution:
The equation of the line.
Now, we compare the given equation by standard form 
So, slope of the line 
, and
y-intercept 
We know that the slope of the perpendicular line 
So, the slope of the perpendicular line
From the above statement, line passes through the point P(6, 6).
Using slope intercept formula to know y-intercept.
Substitute point 
and 
So, the y-intercept of the perpendicular line
Using point slope formula.
Substitute and in above equation.
Therefore: the equation of the perpendicular line
Answer:
66 2/3 %
Step-by-step explanation:
First find the students not in the 8th grade
24 - 8 = 16
16 students are not in the 8th grade
Take the fraction of the students not in the 8th grade over the total
16/24 = 2/3
Change to a decimal
.66666666666
Multiply by 100 to change to a percent
66.666666%
66 2/3 %
The linear equation (y = mx + b) for this particular line is d = 0.6t
it's the same as finding the equation for any line except they use d instead of y and t instead of x. The slope m is 0.6 and intercept is zero.
