Which of the following could NOT be the measures of the angles of a triangle?
A. 30°-120°-30°
B. 40°-40°-100°
C. 60°-60°-60°
D. 70°-50°-70°

Answers

Answer 1

Answer:

D

Step-by-step explanation:

The Triangle Sum theorem states the angles of all triangles will add up to 180.

70 + 50 + 70 = 190. Therefore, this cannot be a triangle.

What is the slope of the line that passes through the points(-4, 0) and (2, 0)?
Write your answer in simplest form.

Answers

Given:

Two points are (-4, 0) and (2, 0).

To find:

The slope of the line that passes through the given points.

Solution:

The line passes through the points (-4, 0) and (2, 0). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{0-0}{2-(-4)}[/tex]

[tex]m=\dfrac{0}{2+4}[/tex]

[tex]m=\dfrac{0}{6}[/tex]

[tex]m=0[/tex]

Therefore, the slope of the line that passes through the points (-4, 0) and (2, 0) is 0.

D 3b. Triangle A has an area of 30cm² and a height of 5. What is the base? ​

Answers

The base of triangle will be 12 cm.

WHAT IS TRIANGLE ? HOW TO FIND ITS AREA ?

A triangle is a three-sided polygon.

The area of a rectangle is commonly known to be b*h, where b is the base and h is the height. Using the formula for a rectangle, we can get the area of a triangle.

A rectangle is split into two congruent triangles by a diagonal. The area of each triangle is equal to half the size of the rectangle.

As a result, the triangle's area A may be calculated using the equation A=1/2*b*h, where b denotes the triangle's base and h its height.

CALCULATION

AREA OF TRIANGLE = 1/2*b*h

base = area of triangle * 2 / h

         = 30 * 2 / 5

         = 12 cm.

what are the smallest values of p and r that satisfy the definitions for parallel lines and perpendicular lines?

Answers

Answer:

p = 2

r = 4

Step-by-step explanation:

If you're doing parallel it needs to be like "side by side." The least you can do is 2 because you'll need at least one other line to be beside the original.

Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.

Since the room temperature is 22 degrees Celsius,

Solving the differential equation,

When t=0, the temperature is 100 degrees.

Flashes of light burst through the darkness, and wind races past my window. The thrilling combination of sight and sound conjures up visions of dragons roaring proudly, breathing fire, and soaring across the midnight sky. Dragons first fascinated me when I was a little girl. They have followed me ever since. The magnificent creatures appeared in storybooks I read in the library, paintings I saw in museums, movies I watched in the theater, and the dreams I had in my sleep. By the time I was thirteen, one question consumed me. I wanted to know if dragons ever existed, so I set out on a quest for facts.2As I started my research, I discovered many skeptics. Scientists presented evidence to show why dragons could notand did notexist. They explained that it would be impossible for dragons to fly because they would be too big. They laughed at the idea of dragons breathing fire. They pointed out that no other animal has ever done this. They said that if dragons had lived, someone would have found remains somewhere in the world. No bones about it, there were plenty of logical explanations. It would have been easy for me to accept that the only place dragons ever existed was in the imaginations of those who believed.3I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed.4With renewed hope that there was some truth to the legends, I looked for new research. I found that some experts disagreed with popular arguments against dragons. They suggested that a dragon could have four stomachs like a cow. If it created stomach gases like birds, it might create enough to lift itself off the ground. This would give it the ability to fly. If it forced out air when diving toward the earth, it might release gases which could ignite into flame. When the animal died, the stomachs would release strong acids that would dissolve its dead body over time. Biologists backed up these ideas with sketches and models based on known animals. Not everyone agreed with these ideas, but many of the things we accept about dinosaurs and other extinct species started the same way.5I doubt we will ever truly know whether dragons existed. There may always be two sides to the fiery debate. Some will say the stories come from active imaginations. Some will believe with all their hearts that the legendary creatures roamed our ancient world. I don't know for certain which side to believe, but the sound and fury of a night like this makes me smile. It rekindles my childhood dreams and keeps the exciting possibility alive.Which sentence from paragraph 4 makes an explicit statement without offering any implicit suggestions? your class nominates one student to attend student government association meetings on behalf of the class and report back on what was discusseda, direct democracyb, representative democracy Read the paragraph from the section "Shellfish."Lower pH values occur naturally on the West Coast during upwelling events, but recent observations indicate that CO2 originating from human activities is contributing to seasonal aragonite undersaturation.
