Step-by-step explanation:

math*

= 81° + a° + a° = 180° ( angle sum property )

[tex]81° + 3a = 180° \\ 3a = 180 - 81 \\ 3a = 99 \\ a = \frac{99}{3} \\ a = 33°[/tex]

The three angles of this triangle are :

[tex] \: ∠1 \:= 81° \\ \: \: ∠2 = 2a = 2 \times 33 = 66° \\ ∠3 = a = 33 \\ \\ ∴ \: a = 33° \: [/tex]

Answer:

105

Step-by-step explanation:

A straight line is worth 180 degrees. Therefore, if you subract the given angle (75) from 180 you will get 105.

180-75=105 degrees.

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

Answer:

X= 60º

Step-by-step explanation:

If you are solving for a ∆, a ∆ has a degree of 180º. This thus when added up gets you.

81º + 39º = 120º

180º - 120º = 60º

Therefore in conclusion, X would be 60º.

y+2>9

-2 on both sides

y>7

-y+3<8

-3 on both sides

-y<5

y is still negative so simply divide both sides by -1

y>-5

The inequality y > 7 represents the solution set of the given compound inequality.

Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.

Given is the following compound inequality.

- y + 3 < 8 and y + 2 > 9

We have -

- y + 3 < 8 and y + 2 > 9

Now, first we will solve inequality (1)

- y + 3 < 8

- y + 3 < 8

- y + 3 - 3 < 8 - 3

- y < 5

y > 5

Solving inequality (2)

y + 2 > 9

y + 2 - 2 > 9 - 2

y > 7

We have two possible solution sets -

y > 5   and   y > 7

To satisfy both the solution sets, the inequality y > 7 will be the final solution of the given compound inequality.

Therefore, the inequality y > 7 represents the solution of the given compound inequality.

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.

Step-by-step explanation:

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.
