Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
Set up the proportion
[tex] \frac{3}{6} = \frac{7}{6 + x} [/tex]
[tex]18 + 3x = 42[/tex]
[tex]3x = 24[/tex]
[tex]x = 8[/tex]

Step-by-step explanation:
(10 pts) A four-lane freeway (two lanes in each direction) is located on rolling terrain and has 12-ft lanes, no lateral obstructions within 6 ft of the pavement edges, and there are 2 ramps within 3 miles upstream of the segment midpoint and 3 ramps within 3 miles downstream of the segment midpoint. A weekday directional peak-hour volume of 1800 vehicles (familiar users) is observed, with 700 arriving in the most congested 15-min period. Ifa level of service no worse than C is desired, determine the maximum number of heavy vehicles that can be present in the peak-hour traffic stream.
Answer:
309
Step-by-step explanation:
To determine the estimated free-flow speed
[tex]FFS = 75.4 -f_{LW}-f_{LC} - 3.22 TRD^{0.84}[/tex]
From the table "Adjustment for lane width," which corresponds to a lane width of 12 feet. As a result, [tex]f_{LW}[/tex] equals 0 mi/h.
Take the meaning from the table "Adjustment for right-shoulder lateral clearance," which corresponds to 6 feet of right shoulder lateral clearance and two lanes in one direction.
The [tex]f_{LC} = 0 mi/h[/tex]
[tex]FFS = 75.4 -0-0-3.22 ( \dfrac{5}{6})^{0.84}[/tex]
[tex]= 72.64 \ mi/h[/tex]
[tex]\simeq 73 \ mi/h[/tex]
Determine the peak-hour factor
[tex]PHF = \dfrac{V}{V_{15}\times 4} \\ \\ =\dfrac{1800}{700\times 4}\\ \\ = 0.6429[/tex]
Now, Find the heavy-vehicle adjustment factor.
[tex]v_P = \dfrac{V}{PHF\times N \times f_{HV}\times f_P} --- (1)[/tex]
Take the value for the 15-minute passenger car equivalent flow rate from the table "LOS requirements for freeway segments" for the FFS and LOS C conditions. The free-flow speed is estimated to be 73 miles per hour
[tex]v_p = 1735+ \dfrac{73-70}{75-70}(1775-1735)[/tex]
[tex]v_p = 1759 \ pc/h/In[/tex]
Think about for familiar users the value of f_p = 1.00
Replace all of the values obtained in (1)
[tex]v_p = \dfrac{V}{PHF \times N\times f_{HV}\times f_p}[/tex]
[tex]1759 = \dfrac{1800}{0.6429\times 2 \times f_{HV}\times 1}[/tex]
[tex]f_{HV} = \dfrac{1800}{0.6429\times 2 }\times \dfrac{1}{1759}[/tex]
= 0.795
Calculate the percentage of trucks and buses in the flow of traffic stream.
[tex]f_{HV} = \dfrac{1}{1+P_{\tau}(E_{\tau}-1) + P_R(E_R-1)}[/tex]
Take the values from the table "Passenger car equivalent for extended highway segments" referring to trucks and buses and rolling terrains for passenger car equivalent for trucks and buses and recreational vehicles. As a result, [tex]E_T[/tex] has a value of 2.5 and [tex]E_R[/tex] has a value of 2.0.
Since [tex]P_R[/tex] is zero and there is no recreational vehicle.
Then;
[tex]0.759 = \dfrac{1}{1+ P_T(2.5 -1) +0}[/tex]
[tex]P_T = 0.1719[/tex]
Finally, to estimate the maximum number of large trucks and buses; we have:
[tex]= V\times P_T = 1800 \times 0.1719[/tex]
Maximum number of large trucks and buses = 309

volume of a cylindrical can of juice is 500cm3 and the diameter of its base is 8 cm find the height of the can of pineapple juice
Answer:
9.95 cm
Step-by-step explanation:
Volume of a cylinder = pi * r² * h
Volume = 500 cm³
Radius, r = 8cm / 2 = 4cm
500 = 3.14 * 4² * h
500 = 3.14 * 16 * h
500 = 50.24 * h
h = 500 / 50.24
h = 9.952229
Height, h = 9.95 cm

evaluate 3 + jk + k ^3 when j = 2 and k = 6
The point (-2, k) lies on the line 2x – 4y + 3 = 0.
Find the value of k.
Answer:
k = (-1/4)
Step-by-step explanation:
Given that,
The point (-2, k) lies on the line 2x – 4y + 3 = 0.
We need to find the value of k.
Put x = -2 and y = k in the given equation.
2(-2) – 4k + 3 = 0
-4-4k = -3
-4+3 = 4k
-1 = 4k
k = (-1/4)
So, the value of k is equal to (-1/4).

What distinguishes a market economy from a free-enterprise economy?
A market economy is based on set prices that businesses use to produce goods that consumers need.
A free-enterprise economy allows the government to freely regulate the quantity of items produced as supply decreases in a market economy.
A market economy is based on supply and demand, and a free-enterprise economy is based on relying on demand to produce products to make money.
In a market economy, the supply and demand of goods is determined by consumers who are free to set their own prices in a free enterprise
Answer:
Well that question could have multiple answers... one of them being set prices, and money balances. Another being product demand on goods and services. It's really your choice on what you think distinguishes these factors. There's to many opinions on this to just give one answer.
Step-by-step explanation:
Answer: It's C. "A market economy is based on supply and demand, and a free-enterprise economy is based on relying on demand to produce products to make money." Good Luck!

For parties of six or more, a restaurant adds a 20% gratuity (or tip). If a
dinner bill for a large party comes to $148.25, find the total dinner bill with
tip.
Answer: tThe total dinner bill with tip = $177.90
Step-by-step explanation:
Given: Dinner bill = $148.25
Tip percent = 20%= 0.20
Total dinner bill = Dinner bill + Tip percent × (Dinner bill)
Total dinner bill = $ (148.25+0.20×148.25)
Total dinner bill = $ (148.25(1.20))
Total dinner bill = $177.90
Hence, the total dinner bill with tip = $177.90
