Answer:
The value is [tex] e = 1.92 [/tex]
Step-by-step explanation:
From the question we are told that
The formula for radius of curvature is [tex]R = \frac{1600}{15} +127e[/tex]
The design speed of the roadway is [tex]v = 40 \ km/hr[/tex]
The value of radius of curvature considered R = 350 m
From the equation given e is the superelevation rate
Now making the subject of the formula
[tex] e = \frac{R}{127} - \frac{1600}{1905} [/tex]
At R= 350
[tex] e = \frac{350 }{127} - \frac{1600}{1905} [/tex]
[tex] e = 1.92 [/tex]
Here, we are required to determine the maximum superelevation rate, e (rounded to 2 decimal places) recommended if the radius of curvature, R is 350 meters.
The answer is e = 1.92 (rounded to 2 decimal places).
First, from the information given, the minimum radius of curvature, R is related to the maximum superelevation rate, e by the formular;
R = (1600/15) + (127e)
Therefore, to evaluate the value of e for R = 350, we have;
350 - (1600/15) = 127e.
350 - (1600/15) = 127e.350 - 106.667 = 127e
Therefore, 243.333 = 127e.
Therefore, e = 1.9160meters
As a result, The maximum superelevation rate, e recommended if the radius of curvature, R is 350 meters is:
e = 1.92 (rounded to 2 decimal places).Read more:

Jose borrowed $1500 from the bank at a rate of 8% simple interest per year. He Paid how much in interest in three years
Answer:
360
Step-by-step explanation:
the answer is $360 because 8% x $1500 = 120 and eventually since it says 3 years we would have to times it by 3 which would equal 360
Jose will $360 in interest in three years.
What is simple interest?Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
Now it is given that,
Principle amount, P = $1500
Rate of interest, R = 8% = 0.08
Time, T = 3 years
Now, since the simple interest paid in T years is given as,
S.I = PRT/100
S.I = 1500*8*3/100
S.I =36000/100
S.I = 360
Simple interest paid in 3 years is $360.
Hence,Jose will $360 in interest in three years.

-3 (4-2x) = 4 - 2x I can't seen to get this one
Let's see what to do buddy...
[tex] - 3(4 - 2x) = 4 - 2x[/tex]
Subtract the sides of the equation minus( 4 - 2x ) :
[tex] - 3(4 - 2x) - (4 - 2x) = 0[/tex]
Factoring ( 4 - 2x ) :
[tex](4 - 2x)( - 3 - 1) = 0[/tex]
[tex](4 - 2x)( - 4) = 0[/tex]
Divided the sides of the equation by -4
[tex]4 - 2x = 0[/tex]
Subtract the sides of the equation minus 4
[tex] - 2x = - 4[/tex]
Negatives simplified.
[tex]2x = 4[/tex]
Divided the sides of the equation by 2
[tex]x = \frac{4}{2} \\ [/tex]
[tex]x = 2[/tex]
