PLEASE HELP
lines m and p are cut by the transversal n. determine the value of x. write the measures of the six angles. show all work

Answers

x = 36

Step-by-step explanation:

The angles 4x and x are supplementary, meaning they add up to 180; therefore we have

[tex]4x + x = 180[/tex]

[tex]5x = 180[/tex]

dividing both sides by 5 gives

[tex]x = 36[/tex]

the measure of angle x is 36 and that of 4x is 4 * 36 = 144

The angle opposite to 4x also measures 144 and the one opposite to x is 36.

Answer:

x° + 4x° = 180°

5x° = 180°

x° = 180°/5

x° = 36°

Help me find the area :)

Answers

Answer:

400 cm²

Step-by-step explanation:

25÷20 = 1.25

Area = 1.25 × 320

= 400 cm²

Answer:

500

Step-by-step explanation:

Base is 20, height is 16, the larger one is 1.25 times larger, so the height of the larger one is 16*1.25=20. This means that the area of the larger one is 20*25=500.

Use the arithmetic series formula to calculate the sum of the first 15 terms of the sequence: a n =5n+3

Answers

Answer:

S₁₅ = 645

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Using the nth term formula [tex]a_{n}[/tex] = 5n + 3 , then

a₁ = 5(1) + 3 = 5 + 3 = 8

a₂ = 5(2) + 3 = 10 + 3 = 13 , then

d = a₂ - a₁ = 13 - 8 = 5

Thus

S₁₅ = [tex]\frac{15}{2}[/tex] [ (2 × 8) + (14 × 5) ]

     = 7.5( 16 + 70)

     = 7.5 × 86

     = 645

A sample of nitrogen gas has a pressure of 6.58 kPa at 539K. If the volume does not
change, what will the pressure be at -62C.

Answers

Answer:

2.575844

Step-by-step explanation:

This is a simple change of temp problem, from 539K to -62C but to start you have to change the C to K, which is simply adding 273 to the -62 so 211K.

Now you take P1/T1 = P2/T2 so,

6.58 = x

539 = 211

now cross multiply and divide, 211 x 6.58 then divide by 539.

this will give you your answer

6 x 2 = 12 and 2 x 2 = 4

which is the solution set for the quadratic equation x^2-9=0

Answers

Answer:  x = 3 and x = -3

===================================================

Explanation:

We could add 9 to both sides, and then apply the square root to both sides. Don't forget about the plus minus

x^2 - 9 = 0

x^2 = 9

x = sqrt(9) or x = -sqrt(9)

x = 3 or x = -3

To check these answers, you replace x with those values we found. I'll show you how to check x = 3

x^2 - 9 = 0

(3)^2 - 9 = 0

9 - 9 = 0

0 = 0

So that confirms x = 3. The confirmation for x = -3 is nearly the same. Keep in mind that (-3)^2 = (-3)(-3) = 9. You'll be squaring the negative as well.

------------------

Another method you could do is to use the difference of squares rule

x^2 - 9 = 0

x^2 - 3^2 = 0

(x - 3)(x + 3) = 0

Now apply the zero product property. This effectively means you set each factor equal to zero and solve for x

x-3 = 0 or x+3 = 0

x = 3 or x = -3

We end up with the same solution set.

Yet another method you could use is the quadratic formula, but that may be overkill. It's still good practice to do.

Graphing is a visual way to find the answers. You'll graph y = x^2 - 9 and look to see where the curve crosses or touches the horizontal x axis.

The equation y=36.5x represents the number of miles, y, that Katherine can drive her car for every, x, gallons of gas. Find the rate of change.

Answers

Answer:

36.5miles/gallon

Step-by-step explanation:

Given the equation y=36.5x which represents the number of miles, y, that Katherine can drive her car for every, x, gallons of gas. The rate of change of the function is expressed as dy/dx

On differentiating the function;

dy/dx = 36.5

Hence the rate of change of the function is 36.5miles/gallon

To begin, read the examples of actions and consequences below, and note how each consequence was unintended. Some European sailors have smallpox. They come in contact with Native Americans and pass the disease on to them. The disease devastates whole cultures. Europeans take potatoes back to the New World. Some European countries become overly dependent on the potato as a main food source. Affluent Europeans buy sugar from the New World. The slave trade burgeons as European colonists buy slaves to work on sugar cane plantations. Conquistadors bring horses with them to the New World. Plains Indians and other Native Americans become expert horsemen.Conduct Research, Choose a Topic, and Write a Thesis StatementConduct some online exploration to find more consequences of the Columbian Exchange, and decide whether they are intended or unintended. Choose one unintended consequence and do in-depth research on it. Gather details such as locations or countries, key people, populations involved, and ways in which the unintended consequence can be seen many years or even centuries later. Then, write the consequence in the form of a question, such as, How did the introduction of the horse to the New World change the lives of Native Americans?Use the question to formulate a thesis statement for your essay. The thesis should answer the question. Using the sample question above, the thesis would be, Plains Indians domesticated horses from Europe. They became famous for their skill in hunting and fighting from horseback. Write your thesis statement in one or two clear sentences.Works Cited:You must have a works cited page.
