George Jones is a 45 year-old who has two felony convictions, one for robbery and one for assault with a deadly weapon. In 2007, he stole some items worth about $100 from a Wall Mart. Jones has admitted stealing the merchandise. His conduct qualifies as petty theft under the state’s criminal code, which is a felony. There is, however, another provision in the code for misdemeanor theft.
If you were the prosecuting attorney in the case against Jones, would you file felony charges against him? Would your answer to the question change if you knew that charging a felony would result in a third strike under the criminal code, so that Jones would be subject to a sentence of 25-years-to-life?
If you were the judge in Jones’s case, would you grant the defendant’s motion to dismiss the felony charge and accept a proposed guilty plea for misdemeanor theft (which could result in a sentence of up to one year in the county jail)?

A 90o v-notch weir is used to measure discharge flow rate. A head (H) of 6 inches is measured behind the weir. Assume the following:
Weir equation is Q = 2.5H2.5 (Q in cfs and H in feet)
1 cfs = 450 gpm
a) Estimate discharge flow rate in gallons per minute (gpm)
b) Briefly describe hydraulic principle of open channel flow measurement
Please show all work. Thank you so much in advance!

The road becomes a class-III two-lane highway after reaching a long bend in the road. The speeds don’t typically change off-peak at the transition, and width/clearance/access are consistent after the transition too. There are 50% no passing zones. What is the LOS of the two-lane highway?

A concrete mix design is needed for a residential street paving project in Detroit, Michigan. Pavement thickness is 8”, unreinforced, subjected to freezing and thawing and deicing agents are anticipated. The specified compressive strength is 4000 psi. Assume both Fine Aggregate (FA) and Coarse Aggregate (CA) are in saturated surface dry condition.
Specific Gravity of Fine Aggregate (FA) = 2.71
Fineness Modulus (FM) of Fine Aggregate (FA) = 2.70
Specific Gravity of Coarse Aggregate (CA) = 2.65
Bulk Density of Coarse Aggregate (CA) = 105 pcf
Nominal Maximum Size of Coarse Aggregate = ¾”
Specific Gravity of Cement = 3.15

Please provide a step-by-step solution, with "Given:", "Find:", and "Solution:" format, for the problem below. Please be sure to include any tables, values, and references required to arrive at the solution you provide so that the process may be repeated for other values.
Horizontal Formwork Design
Given: 6 in structural steel-concrete floor slab. Use ¾ in Class I plyform parallel to the span for the sheathing and Southern Yellow Pine #2 for the rest of the lumber. Joists will be 2x8 and stringers will be 6x8. Unsupported height of shores will be 10 ft and they will be S4S. The maximum deflection for sheathing may be taken as 1/360 of the span. Motorized buggies will be used to transport normal weight concrete.
Find: Design the formwork for this slab.
Solution: Show all your work.
