100 * 100 is 10,000
and it's already rounded so we don't need to do anything else...

When estimating a job to bid, a contractor’s estimator first determines the actual cost of labor using the function

CaHeK987 [17]

Answer:

M(B(h))=78.18025h

Step-by-step explanation:

First we have the following equations:

L(h) = 28.75h eq. 1

B(L) = 1.78L eq. 2

M(B) = 1.43B eq. 3

To find the selling price based on the estimated number of hours, we need to start replacing equation 1 in equation 2 as:

B(L) = 1.78*B

B(L(h)) = 1.78*(28.75h)

B(L(h)) = B(h) = 51.175h eq. 4

Finally, if we weplace equation 4 in equation 3, we get:

M(B) = 1.43B

M(B(h)) = 1.43*(51.175h)

M(B(h)) = 73.18025h

So, the composite function that can be used to find the selling price for the labor portion of a bid based on the estimated number of hours is:

M(B(h)) = 73.18025h

Answer:

Average waste per day per person =1.51 pounds

Step-by-step explanation:

In 2010 do United States has a population of 309 million people. Also in the year 2010, do United States recycled 170,000 million pounds of waste.

We have to find the the average waste per person per day.

In a year there are 365 days.

In a day, the average amount of waste produced = $\frac{total waste}{365}$

= $\frac{170,000}{365}$

= 465.75 million pounds of waste

To find the average amount of waste produced per person per day, divide the average amount of waste produced per day by the total number of people in the country.

Average waste per day per person = $\frac{465.75}{309}$

= 1.51 pounds
