Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 4 minutes. When taking off, the run time of an airplane on the runway is 24 seconds. Planes are on average waiting 5 minutes and 54 seconds for take-off. On average there are 12 planes taking off per hour. How many planes are either on the runway or waiting to take off?

Answers

Answer:

1 plane either on the runway or waiting to take off

Step-by-step explanation:

We are given;

Frequency of take off = 12 planes per hour = 12/60 = 0.2 planes per minute

Waiting time on runway = 5 minutes 54 seconds = 5.9 minutes

Run time on runway = 24 seconds = 24/60 minutes = 0.4 minutes

To solve this question, we will use Little's law which is given by the formula;

System inventory = rate of flow × throughput time

Now, rate of flow is the same as Frequency of take off.

Thus, rate of flow = 0.2 planes per minute

Throughput time = Waiting time on runway + Run time on runway

Thus;

Throughput time = 5.9 minutes + 0.4 minutes

Throughput time = 6.3 minutes

Thus;

System inventory = 0.2 × 6.3 = 1.26 planes

Thus is approximately 1 plane.

f(x) = 3x - 5 and g(x) = 5x + 8. Find 3g(x) - 2f(x).

Answers

Answer:

9x + 34

Step-by-step explanation:

3g(x) - 2f(x); f(x) = 3x - 5 & g(x) = 5x + 8.

3(5x + 8) + - 2(3x - 5) (Plug g(x) & f(x) into equation)

15x + 24 + - 6x + 10 (Use distributive property)

9x + 34 (Combine like terms) - This is as much as it can be simplified.

Answers

Answer: 3a^2+6ab+3b^2-2a-2b-1

Step-by-step explanation:

For G(x), we must plug in (a+b) into G(x):

G(a+b) = 3(a+b)^2-2(a+b)-1

= 3(a+b)(a+b)-2(a+b)-1

= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1

= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1

= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1

What the solution for x is in 14+x=3a+ab?

Answers

Answer: a= x+14 /b+3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Simplifying

14 + x = 3a + ab

Solving

14 + x = 3a + ab

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14' to each side of the equation.

14 + -14 + x = 3a + -14 + ab

Combine like terms: 14 + -14 = 0

0 + x = 3a + -14 + ab

x = 3a + -14 + ab

Reorder the terms:

x = -14 + 3a + ab

Simplifying

x = -14 + 3a + ab
