A bike ramp has a slope of 1/4. What is the angle the ramps makes with the ground to the nearest degree?

Mathematics

The slope is equivalent to the rise over run. Since the slope of the bike ramp is ¼, the rise is equivalent to 1 and the run is equivalent to 4. To get the angle of the bike ramp make with the ground, let us use the equation tanθ= rise/run.

Therefore, tanθ= ¼.  

Θ=tan-1 (1/4)

So the angle of the bike ramp is Θ= 14degrees

The scheduled arrival time for a daily flight from Boston to New York is 9:30 am. Historical data show that the arrival time fol
Galina-37 [17]

Answer:

Step-by-step explanation:

Let x be a random variable representing the flight arrival time from Boston to New York.

For a uniform probability distribution, the notation is

X U(a, b) where a is the lowest value of x and b is the lowest value of x

The probability density function, f(x) = 1/(b - a)

Mean, µ = (a + b)/2

Standard deviation, σ = √(b - a)²/12

From the information given, the time difference in minutes is 9:57 - 9:07 = 50 minutes. Therefore,

a = 0

b = 50

µ = (0 + 50)/2 = 25

σ = √(50 - 0)²/12 = 14.43

b) converting to minutes, it is 9:30 - 9:07 = 23 minutes

the probability that a flight arrives late(later than 9:30 am) is expressed as P(x > 23)

f(x) = 1/(50) = 0.02

P(x > 23) = (50 - 23)0.02 = 0.54

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Include your work in
slava [35]

Answer:

y-5=-1/2(x+3)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-5)/(-1-(-3))

m=-1/(-1+3)

m=-1/2

y-y1=m(x-x1)

y-5=-1/2(x-(-3))

y-5=-1/2(x+3)

Use the Babylonian method of false position to solve the following
Mice21 [21]

Answer:

  • length: 32
  • width: 24

Step-by-step explanation:

<u>Assume a solution</u>

Assume that 60 is the length. The width is then 1/4 less, or 60 -60/4 = 45.

The diagonal of this rectangle is found using the Pythagorean theorem:

  d = √(60² +45²) = √5625 = 75

<u>Make the adjustment</u>

This is a factor of 75/40 larger than the actual diagonal, so the actual dimensions must be 40/75 = 8/15 times those we assumed.

  length = (8/15)×60 = 32

  width = (8/15)×45 = 24

The length and width of the rectangle are 32 and 24, respectively.

_____

<em>Comment on this solution method</em>

This method is suitable for problems where variables are linearly related. If we were concerned with the area, for example, instead of the diagonal, we would have to adjust the linear dimensions by the <em>square root</em> of the ratio of desired area to "false" area.
