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

= add/subtract: 3a^2+6ab+3b^2-2a-2b-1

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.

Solve this inequality. -y + 3 < 8 and y + 2 > 9

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

What is 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.

Which equation has exactly one solution in common with the equation y=6x-2?

A. 18x - 3y = 6
B. 1/2y = 3x - 2
C. 2y = 4x - 12
D. 18x - 12 = 3y

Answers

Answer:

A. 18x - 3y = 6

Step-by-step explanation:

By taking 3 common from the terms 18x and 3y we get,

3 (6x-3y) = 6

or, 6x - y = 6/3

or, 6x - y = 2

And,

The equation becomes,

y = 6x - 2

The equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

By taking 3 commons from the terms 18x and 3y we get,

3 (6x-3y) = 6

6x - y = 6/3

6x - y = 2

The equation becomes,

y = 6x - 2

Therefore, the equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

Determine the preferred width of each class if you use 8 classes, a high of 87, and a low of 2. (this is a statistics question)

A. 15
B. 13
C. 11
D. 10

Answers

Answer:

11 ; C

Step-by-step explanation:

To get the class width, we start by finding the range of the data set

That will be; the highest number - the smallest number

= 87-2 = 85

We proceed by dividing the number of classes we want by this number

That will be 85/8 = 10.625

We now proceed to approximate this value to the nearest whole number = 11

Hence , 11 is the class width to use

why would a cell make and store fat? PLZZZZZZZZZZZZZZZZ HELP ME i begging YOUUUUU !!!!!!!!!!!!!!!!!!!!!!!!!!!What countries sent the First Explorers?Portugal The Portuguese were the first successful explorers because of their guns and seamanship. With their large cannons, their fleet was able to defeat most ships and armies they came across. Beginning in 1520, Portuguese fleets probing south along the western coast of Africa. There, they discovered a new source of gold. For this reason, the southern coast of West Africa became known as the Gold Coast. The explorer Vasco da Gama sailed around the southern tip of Africa, called the Cape of Good Hope, and cut across the Indian Ocean to reach India. After people heard about de Gamas profits, many more Portuguese sailed the same route to India, setting up posts in Africa along the way. Spain Educated Europeans knew the world was round, but they had no idea of how big it was. The Spanish thought that they could find new routes to India and China by sailing west across the Atlantic Ocean. Christopher Columbus persuaded the king and queen of Spain to pay for his voyage sailing west to reach Asia. With his three ships, Columbus reached the islands of Cuba and Hispaniola (which would later become Dominican Republic and Haiti). As he traveled to most islands in the Caribbean, Columbus thought he had reached Asia. This false belief is why the Europeans called the people they found Indians they thought they were in India. Another important explorer for Spain was Ferdinand Magellan. Magellan succeeded in reaching Asia by sailing west across the Atlantic by going around the southern tip of South American and continuing west across the Pacific Ocean. Magellan reached the Philippines in Asia, where he was killed by local natives. However, one of his ships continued on to Spain, and Magellan is given credit as being the first to sail around the entire world. The Spanish and Portuguese began competing for the territories they found in the New World. Eventually they would sign a treaty, agreeing which lands each country would be allowed to take over. The new lands were given the general name America, after the Italian explorer Amerigo Vespucci. After the success of Spain and Portugal in exploring the Americas, the Dutch, the English, and the French began sending expeditions to find new places to trade in the Americas. The European explorations would change life not only for Europeans, but also for the native peoples of South America, North America, and Africans as well.7.
