Given <span>that Marucs lays a slab of concrete in 6 hours and Tony lays the same slab in 4 hours. If both work on the job, the number of hours it will take them to lay the slab is given by:

\frac{1}{t} = \frac{1}{6} + \frac{1}{4}  \\  \\ = \frac{2+3}{12} = \frac{5}{12}  \\  \\ \Rightarrow t= \frac{12}{5} =2.4\ hours

Given that </span><span>the cost of labor is $44.00 per hour, t</span>herefore, <span>the labor estimate should be 2.4 </span>x 44 = $105.60 per slab.

Explanation:

When I was in school grade 9, I had my first interaction with a robot during a visit to technology expo since then I could not think of anything else but to awe for exploring the fascinating world of robots.

I didn't had much resources to buy tools and components to build robots but still my passion kept me motivated and I found my way to get hands on scrap parts available at the various spots in my locality. Slowly and gradually, I kept learning and building robots and by the time I was in my high school, I had already won 3 major school competitions and received tremendous amount of recognition. Due to my outstanding performance, I was awarded with merit scholarship for the college.

In college, I continued my handwork and kept myself busy in exploring the depth of robotics. I had the pleasure of working on a big project funded by a our college. The project was to build a search and rescue quad-copter. Honestly speaking, it was not easy! I worked day and night tirelessly, and finally after 6 months I successfully built the quad-copter.

My goal is to become an inventor in the field of robotics. Building such robots that can make a difference in our lives and help humanity to grow and thrive. I believe that engineering program at Princeton encourages such passion and vision and would be a great learning platform for me to showcase my talent and skills.

A major reason why it is difficult to lower the barriers to free trade is A. the loss of jobs without any gain of jobs from free
Thepotemich [5.8K]

Answer:

B) the uneven distribution of gains and losses from free trade.

Explanation:

One of the most important reasons why governments impose trade barriers is to protect domestic jobs (and domestic industries). We are part of a society (country), and society's most important component is people, not money. Generally the economic gains of free trade are larger than the economic losses, but the economic losses hurt the most.

Imagine if no trade barriers actually existed, how many millions of jobs would be lost in the US. Trade barriers are nothing new, the current president didn't invent them. He just incinerated them.

How does a leader tell the people that 10 or 20 million must lose their jobs and probably will not be able to find any similar jobs in the future just because the rest of society will benefit from cheaper products. The lives of 20 million households (50-80 million people) would be destroyed, while 280 million people would benefit.

The amount of harm done to the people that lose their jobs is much greater than any individual benefit.
