Answer 1
Use the formula
V = pi(r^2)(h)
r = 3.75, h = 6.21
V = pi(3.75^2)(6.21)
V = pi(87.33)
V = (3.14)(87.33) = around 274
Now you can figure out the rest

Combine like terms: 6r + r = 7r

Combine like terms: 7r + -5r = 2r

2r = 0

Solving

2r = 0

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Divide each side by '2'.

Using relations in a right triangle, it is found that the sine of 23 degrees is given by:

D. 5/13.

What are the relations in a right triangle?

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Looking at the graph, the side opposite to the angle of 23º is of 5, while the hypotenuse is of 13, hence the sine is given by:

sin(23º) = 5/13.

Which means that option D is correct.

simplify by expressing with radicals n√x^3^n​

Answers

We can work with the exponents to simplify our expression, and we will get:

[tex]\sqrt[n]{x^{3n}} = x^3[/tex]

How to simplify the expression?

Remember that a root of degree n is equivalent to an exponent of 1/n.

This means that we can rewrite a root of degree n as:

[tex]\sqrt[n]{x} = x^{1/n}[/tex]

Then our expression:

[tex]\sqrt[n]{x^{3n}}[/tex]

Can be rewritten as follows.

[tex]\sqrt[n]{x^{3n}} = (x^{3n}})^{1/n}[/tex]

Now we have the exponent of an exponent, that means that we just need to take the product between the two exponents.

Now we can take the product of the exponents to get.

[tex]\sqrt[n]{x^{3n}} = (x^{3n}})^{1/n} = x^{3n*1/n} = x^3[/tex]

You can see that in the third step the exponents n and 1/n cancell eachother, so we end only with the exponent 3.

That is the expression simplified.

A room is 15 feet long and 12 feet wide. A scale drawing of the room is 10 inches by 8 inches. What is the scale of inches in the drawing to inches in the actual room?

Enter the correct answer in the box.

Answers

Answer:

The scale is 1:18 for the entire room, 1 inch in the diagram for 18 inches IRL

Step-by-step explanation:

12 inches = 1 foot

Convert the feet to inches, then divide both sides of the ratio by the # of inches in the diagram

So for length:

10:(15*12)

10:180

1:18

And for width:

8:12(12)

8:144

1:18

Answer:

18 inches

Step-by-step explanation:

The question asks for scale of inches in the drawing and the actual room, so first convert 15 ft and 12 ft into inches.

1 foot= 12in x 1ft= 12 inches

15 feet= 12in x 15ft = 180 inches

12 feet= 12in x 12ft = 144 inches

The room is 180 inches long and 144 inches wide.

To find the scale, set up a proportion to the drawing to the room.

[tex]\frac{10}{8} =\frac{180}{144}[/tex]

You can see that the scale is 18 inches because to get from 180 to 10, you multiply by 18, and the same thing as 8, you would multiply 8 by 18 to get to 144.

In what time will $1000 amount to $1331 at 10% per annum, compounded annually?​

Answers

The time is 3 years


Step by step explanation:
Answer:

3 Years

Step-by-step explanation:

Compound interest is a multiplier that affects the new value each time.

If the compound interest is 10% per annum, the multiplier each year is 1.1.

Year 1: $1000 * 1.1 = $1100

Year 2: $1100* 1.1 = $1210

Year 3: $1210* 1.1 = $1331

This means that it will take 3 years for $1000 to amount to $1331 at 10% per annum.

Alternatively, you can use a logarithm. The calculation can be written as:

1000 * [tex]1.1^n[/tex] = 1331, where n is the number of years.

Rearranged, this gives [tex]1.1^n[/tex] = 1331/1000 or [tex]1.1^n[/tex] = 1.331.

A logarithm can work out the value of n, and is written in the form log1.1(1.331), which gives a value of 3.

Find the x- and y-intercepts of the graph of -x+2y=6. State each answer as an integer or an improper fraction in simplest form.

Answers

Given the linear equation, -x + 2y = 6, we can set y = 0 to find the x-intercept.

The x-intercept is the point on the graph where it crosses the x-axis, and has coordinates of (a, 0), where a = x-intercept.


-x + 2y = 6
-x + 2(0) = 6
- x + 0 = 6
-x = 6

Divide both sides by -1 to isolate x:
-x/-1 = 6/-1

x = -6

Therefore, the x-intercept is (-6, 0), where its x-coordinate, a = -6.

Next, in order to solve for the y-intercept, set x = 0.

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b), where b = y-intercept.

-x + 2y = 6
-(0) + 2y = 6
0 + 2y = 6
2y = 6

Divide both sides by 2 to isolate y:

2y/2 = 6/2

y = 3

Therefore, the y-intercept is (0, 3), where its y-coordinate, b = 3.

They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.What is the main purpose of including the story of Ginny wanting to care for blind or deaf cats? To create awareness of the need to give to animal shelters To explain the owner's role in training Ginny To show that Ginny was aware of cats with special needs.
