The lines 3y-x=3 and y+3=3(x-1) are

Answers

Answer 1
Answer: Lets change the form of the equations to the canonical line equation form:
 y = mx + b

3y - x = 3
y = (1/3)x + 1

y + 3 = 3(x - 1)
y = 3x - 6

What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet? Use 3.14 for pi

Answers

Answer:

The answer is 150.72!

Step-by-step explanation:

Formula: Volume = radius^2*height*pi

So all you need to do is multiply 3.14(pi) times the height times the radius squared. To square a number means to multiply the number by itself one time!

Sooo....

3 x (4*4) x 3.14 = 150.72

I hope this helps!

The tax on a $400 painting is $34. What should be the tax on a $700 painting

Answers

if  tax on a $400 painting is $34. then tax on a $700 painting is $59.5.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

A proportion is an equation in which two ratios are set equal to each other.

By the given data

tax on a $400 painting is $34.

We need to find tax on $700 painting.

Let x be the  tax on a $700 painting.

Let us formulate an equation by using given data

400/34=700/x

Apply cross multiplication

400x=700×34

400x=23800

Divide both sides by 400

x=59.5

Hence if  tax on a $400 painting is $34. then tax on a $700 painting is $59.5.

$59.50 I think, because 400/34=700/x so 34x700/400=59.5

Jonas wants to make a poster of a drawing he made. the original drawing was 8 inches wide he wants the poster to be 30 inches wide. what zoom button setting will he have to use on the library copier to create a poster of this size ?

Answers

Answer:

The answer is 375

Step-by-step explanation:

Here's one way to solve this problem.

1. Let x represent the copier zoom button setting.

2. Write the ratio of the original percent to the copy percent:

100%/ x%

3. Write the ratio of the original width to the copy width

8in./30in.

4. write the proportion equating the two ratios:

100/x = 8/30

5. Cross multiply:

8x = 30 × 100

8x = 3,000

6. Divide both sides by 8:

x = 375

So Jonas will have to use a copier zoom button setting of 375% to create a poster 30 inches wide.

Hope this helped!

Answer:

Times 3.75 zoom button.

Step-by-step explanation:

Jonas drawing is 8 inches wide.

He wants to make a poster which is 30 inches wide.

The library copier will have to zoom the drawing 30 ÷ 8 = 3.75 times to make the poster.

So the zoom factor button is times 3.75 button.

What is the product of the polynomials below? (x - 5)(x2 + 4x - 2) HELP ASAP please

Answers

(x - 5)(x² + 4x - 2)

Distribute each term from one parenthesis to all the other terms in the other

x(x²) = x³

x(4x) = 4x²

x(-2) = -2x

-5(x²) = -5x²

-5(4x) = -20x

-5(-2) = -10

Combine all like terms:

x³ + 4x² -5x² -2x -20x -10

x³ - x² - 22x - 10 is your answer

hope this helps

(x - 5)(x^2 + 4x - 2) = 
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2) =
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10 =
x^3 - x^2 - 22x + 10

A rectangular prism with a volume of 222 cubic units is filled with cubes with side lengths of \dfrac14 4 1 ​ start fraction, 1, divided by, 4, end fraction unit. How many \dfrac14 4 1 ​ start fraction, 1, divided by, 4, end fraction unit cubes does it take to fill the prism?

Answers

The correct question is
A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4 unit. How many cubes does it take to fill the prism?

we know that
[volume of the cube]=b³
b=1/4 unit
[volume of the cube]=(1/4)³------> 1/64 unit³

if 1 cube has a volume of ----------------> (1/64) unit³
x cubes--------------------------------> 2 unit³
x=2/(1/64)-----> x=2*64----> x=128 cubes

the answer is
128 cubes

Answer:

128
