The modulus of elasticity is 44.4GPa

E<u>xplanation:</u>

Given

original length L1=10cm

New length L2=10.036 cm

Force F=16000N

dimensions\ of\ the\ bar\ is\ 1 cm\times1cm\\Area=1cm\times1cm=1cm^2=0.0001m^2

Stress of the bar σ=Force/Area

=16000/0.0001=16\times 10^7N/m^2

Change in length ΔL=L2-L1=10.036-10=0.036 cm

Strain is obtained by dividing the change in length by original length

Strain ε=ΔL/L1

=0.036/10=0.0036

Modulus of elasticity=stress/strain

=σ/ε

=16\times10^7/0.0036\\=4.44\times10^\ 10Pa

=44.4GPa

Five hundred gallons of 89-octane gasoline is obtained by mixing 87-octane gasoline with 92-octane gasoline. (a) Write a system
miskamm [114]

Explanation:

a) The total volume equals the sum of the volumes.

500 = x + y

The total octane amount equals the sum of the octane amounts.

89(500) = 87x + 92y

44500 = 87x + 92y

b) desmos.com/calculator/ekegkzllqx

As x increases, y decreases.

c) Use substitution or elimination to solve the system of equations.

44500 = 87x + 92(500−x)

44500 = 87x + 46000 − 92x

5x = 1500

x = 300

y = 200

The required volumes are 300 gallons of 87 gasoline and 200 gallons of 92 gasoline.

PtichkaEL [24]

The correct answer is A. Earning a bachelor's degree in Civil Engineering from a four-year university, completing an internship, and seeking a job at a private firm.

Explanation:

In the U.S. and many countries, the best to start a career is to enroll in a formal educational program at a university or college. This helps students learn concepts, theories, methods, etc. they need for their profession. Moreover, a degree such as a bachelor's degree is required by employers. In this context, the first step for Connor is to earn a bachelor's degree in Civil Engineering.

Besides this, an internship is recommended after earning a degree because this is the way students can gain real-life work experience, which is considered positive by employers. This means the next step should be an internship.

Finally, Connor can seek a job to design bridges and other buildings because after the degree and internship he will have the experience and knowledge required by employers and by the job.
