Answer:
a= c+16
a-c= 16
Step-by-step explanation:
a = b + 12
b = c + 4
adding both eq.s, we get:
a+b = b+c+12+4
a+b = b+c+16
a = c+16
a-c = 16
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?
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.

G(a + b) =
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
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1
Answer: 3a^2+6ab+3b^2-2a-2b-1
Answer:
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
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1

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

Do these 3 side lengths form a right triangle? (Yes or no question): 10 cm, 49.5 cm, 50.5 cm
Answer:
yes
Step-by-step explanation:
By the converse of Pythagoras' identity.
If the longest side squared is equal to the sum of the squares of the other 2 sides, then the triangle is right.
longest side = 50.5
50.5² = 2550.25
10² + 49.5² = 100 + 2450.25 = 2550.25
Thus the given triangle is right.
Answer:
yes and no

Tonya's class planted sunflowers and the students are tracking the growth of their individual plants. The table
shows the height of
Tonya's plant t days after she planted her sunflower seed
Based on the data in the table, what function h(t) represents the height, h, in inches, at time t?

Answer:
Here's what i did
Step-by-step explanation:
The answer is h = 0.4t
A linear function is a function in the form of:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
We can use the data in the table to find the relationship between the time (t) and height (h)
Let us use the format (height, time). Hence from the table, we have the points:
(4, 10), (8, 20), (12, 30) and (16,40). Using any two points, in this case (4, 10) and (16,40), we can apply the formula:
[tex]h-h_1=\frac{h_2-h_1}{t_2-t_1} (t-t_1)\\\\h-4=\frac{16-4}{40-10} (t-10)\\\\h-4=0.4(t-10)\\\\h-4=0.4t-4\\\\h = 0.4t[/tex]
