b² - 5c if b = 15 and c = 9

Answers

Answer:

180

Step-by-step explanation:

Here,

b=15

c=9

Now,

[tex]=b^{2}-5c\\\\=15^{2} -5*9\\\\=225-45\\\\=180[/tex]

Answer:

180

Step-by-step explanation:

b^2-5c

Substitute 15 in for b

15^2=225 -> 225-5c

Substitute 9 in for c

5(9)=45

225-45 = 180

Step-by-step explanation:

What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.

Answers

Let's say we start with the true statement that 2 < 5

Multiplying each of those numbers by -1 means we have...

2 turn into -25 turn into -5

If the inequality sign stayed the same, then we'd have the false statement -2 < -5. Use a number line to see why this is false. Note how -2 is to the right of -5, so it should be larger.

To fix this error, we flip the inequality sign.

So we go from 2 < 5 to -2 > -5

Rule: Multiplying both sides by a negative number always flips the inequality sign.

Can somebody explain how to find an area of a square?
Please note that the area's side lengths are all the same.
(The side lengths are all 1/3 or also known as 0.3333)

Answers

Answer:

0.66653334

Step-by-step explanation:

The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

Finding are of a square is the same as any other shape, even if the sides are all the same length. You multiple length by width (1/3x1/3) which gives you about 0.1111

Answer:

There are six faces on the solid.

There are twelve edges on the solid.

There are eight vertices on the solid.

Step-by-step explanation:

The 3-D solid shape is a cube.

A cube is a regular hexahedron.

Hexahedron is a polyhedron with six faces (regular meaning all six are square).

So, there are six faces on a cube.

A cube has 12 edges because all faces are squares and congruent to each other, all 12 edges are the same length.

A vertex is a corner where edges meet. The plural is vertices.

a cube has eight vertices, a cone has one vertex and a sphere has none.

B) Two and three eighths plus six and four fifths equals eight and twelve fourtieths
C) Three and three sevenths plus four and two thirds equals seven and two twenty ones
D) Four and five sixths plus five sevenths equals nine and ten thirteenths

Answers

Answer:

A) Three and three ninths plus seven and six elevenths equals 10 and eighty seven ninety ninths

Step-by-step explanation:

Translate these into numerical values: 3 3/9 + 7 6/11 = 10 87/99

Find a common denominator or multiple that your denominator's (9 and 11) share. Their lowest common multiple is 99.

Take 3 3/9's and multiple the denominator by 11 to get your denominator of 99. What you do to your denominator also must be reflected in your numerator, so multiply it by the same factor of 11. You will get 3 33/99

Repeat for 7 6/11. Multiply your denominator (11) by 9 to get your denominator of 99. Do the same in the numerator (6) to get 54.

Now add your new values. 3 33/9 + 7 54/99
Your fractional values will add up to 87/99, and your whole number values will add up to 10. In this case, your fractional values do not exceed 1, so there is no need to work any further. Your final answer is 10 87/99

Simplify

-(w+4)+2(4w-4)

help plz :’)

Answers

Answer:

The simplified answer is 7w - 12.

Step-by-step explanation:

-1(w+4) + 2(4w-4)

(-w -4) + (8w - 8)

7w - 12

Answer:

7w - 12

Step-by-step explanation:

-(w+4)+2(4w-4)

Step 1: Distribute

In this equation, there are two things being distributed, the -(w+4) and the 2(4w-4). Looking at -(w+4) makes you think that there is nothing to distribute but actually there is. Treat the - like a -1 so that it looks like -1(w+4) and then we distribute normally.

-1 x w = -w

-1 x 4 = -4

Put it together and you have:

-w-4

Then the 2(4w-4), with this, we need to distribute the 2 into the 4w and -4. To do this, you just multiply the numbers.

2 x 4w = 8w

2 x -4 = -8

Put those together and you have:

8w-8

After distributing, the equation should like:

-w-4+8w-8

Step 2: Combine Like-Terms

In the remaining equation, there are 4 things we can combine. The -w and 8w, and the -4 and -8. The reason that we are doing it in this order is because you cannot combine a number with a variable, like combining -4 with 8w. Now we just add (or subtract).

8w - w = 7w

-4 - 8 = -12

Leaving us with the fully simplified equation:

7w - 12

Read the excerpt below and then answer the question that follows:The Book of DragonsChapter III The Deliverers of Their Country, an excerptBy E. NesbitIt all began with Effie's getting something in her eye. It hurt very much indeed, and it felt something like a red-hot sparkonly it seemed to have legs as well, and wings like a fly. Effie rubbed and criednot real crying, but the kind your eye does all by itself without your being miserable inside your mindand then she went to her father to have the thing in her eye taken out. Effie's father was a doctor, so of course he knew how to take things out of eyes.When he had gotten the thing out, he said: "This is very curious." Effie had often got things in her eye before, and her father had always seemed to think it was naturalrather tiresome and naughty perhaps, but still natural. He had never before thought it curious.Effie stood holding her handkerchief to her eye, and said: "I don't believe it's out." People always say this when they have had something in their eyes."Oh, yesit's out," said the doctor. "Here it is, on the brush. This is very interesting."Effie had never heard her father say that about anything that she had any share in. She said: "What?"The doctor carried the brush very carefully across the room, and held the point of it under his microscopethen he twisted the brass screws of the microscope, and looked through the top with one eye."Dear me," he said. "Dear, dear me! Four well-developed limbs; a long caudal appendage; five toes, unequal in lengths, almost like one of the Lacertidae, yet there are traces of wings." The creature under his eye wriggled a little in the castor oil, and he went on: "Yes; a bat-like wing. A new specimen, undoubtedly. Effie, run round to the professor and ask him to be kind enough to step in for a few minutes.""You might give me sixpence, Daddy," said Effie, "because I did bring you the new specimen. I took great care of it inside my eye, and my eye does hurt."The doctor was so pleased with the new specimen that he gave Effie a shilling, and presently the professor stepped round. He stayed to lunch, and he and the doctor quarreled very happily all the afternoon about the name and the family of the thing that had come out of Effie's eye.But at teatime another thing happened. Effie's brother Harry fished something out of his tea, which he thought at first was an earwig. He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth. There it sat, stroking itself with its feet and stretching its wings, and Harry said: "Why, it's a tiny newt!"The professor leaned forward before the doctor could say a word. "I'll give you half a crown for it, Harry, my lad," he said, speaking very fast; and then he picked it up carefully on his handkerchief."It is a new specimen," he said, "and finer than yours, Doctor."It was a tiny lizard, about half an inch longwith scales and wings.So now the doctor and the professor each had a specimen, and they were both very pleased. But before long these specimens began to seem less valuable. For the next morning, when the knife-boy was cleaning the doctor's boots, he suddenly dropped the brushes and the boot and the blacking, and screamed out that he was burnt.And from inside the boot came crawling a lizard as big as a kitten, with large, shiny wings."Why," said Effie, "I know what it is. It is a dragon like the one St. George killed."And Effie was right. That afternoon Towser was bitten in the garden by a dragon about the size of a rabbit, which he had tried to chase, and the next morning all the papers were full of the wonderful "winged lizards" that were appearing all over the country. The papers would not call them dragons, because, of course, no one believes in dragons nowadaysand at any rate the papers were not going to be so silly as to believe in fairy stories. At first there were only a few, but in a week or two the country was simply running alive with dragons of all sizes, and in the air you could sometimes see them as thick as a swarm of bees. They all looked alike except as to size. They were green with scales, and they had four legs and a long tail and great wings like bats' wings, only the wings were a pale, half-transparent yellow, like the gear-boxes on bicycles.Based on the exposition in the bolded paragraph, what do we know about Effie?
