Answers

Answer 1

Step-by-step explanation:

113,1 cm^3

Answer 2

The volume of the sphere is V = 113.097 cm³

What is a Sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the radius of the sphere be r = 3 cm

Let the volume of the sphere be V

The formula for the volume of a sphere is:

V = (4/3)πr³

where r is the radius of the sphere and π (pi) is a mathematical constant approximately equal to 3.14159.

Substituting r = 3 cm into the formula, we get:

V = (4/3)π(3 cm)³

V = (4/3)π(27 cm³)

V = (4/3)(3.14159)(27 cm³)

V = 113.097 cm³

Hence , the volume of the sphere is 113.097 cm³ when the radius is 3 cm.

CAN SOMEONE PLEASE HELP?!

Answers

Answer:

70in.

Step-by-step explanation:

Since the given formula for perimeter is [tex]2l + 2w[/tex], all that's needed is to fill in the blanks with the numbers they give us.

[tex]2l + 2w[/tex] (Fill in for given length and width)

[tex]2(20)+2(15)[/tex] (Multiply)

[tex]40 + 30[/tex] (Add)

[tex]70[/tex]

It tells us that length ([tex]l[/tex]) is 20 and that width ([tex]w[/tex]) is 15. So all that we have to do is use the equation it gave us to solve the equation.

I hope this helped :)

Step-by-step explanation:

Hey there!

Here;

Length (l) = 20 in

Width (w) = 15 in

Perimeter(p) = ?

We have;

Perimeter of rectangle (p) = 2l + 2w

= 2(l+w)

= 2(20+15)

= 2*35

= 70 inches

Therefore, perimeter of rectangular picture is 70 inches.

in what ratio we increase 900 to get 1200

Answers

Answer:

4:3

Step-by-step explanation:

Let's say that the number we multiply to get to 1200 from 900 is x.

900x=1200

Now, we divide both sides by 900:

x=1200/900

x=4/3

The number is 4/3. In ratio form, this is 4:3

Answer:

3 : 4

Step-by-step explanation:

900 : 1200

= 30 x 30 : 30 x 40

= 30 : 40

= 3 x 10 : 4 x 10

= 3 : 4

Line A (y=4x+2) is transformed into Line B (y=x+5). Which best describes the new slope and y-intercept?

Answers

Answer:

The new slope is 1 and the line is shifted flatter.

Step-by-step explanation:

Line A slope is 4.

Line B slope is 1.

The y-intercept rose up 3

As far as slope, it became flatter because the line only rises 1 'square' for every 1 'square' it travels to the right. It was rising 4 'squares' for every 1 to the right.

Emma read the statement “the quotient of six and a number, x, is the same as negative two times the difference of x and 4.5.” She translated it as shown below.

6 x = negative 2 x minus 4.5

What errors did Emma make? Select two options.
She should have used division to represent the quotient of six and x.
She should not have included an equal sign.
She should have used parentheses to show that Negative 2 is multiplied by (x minus 4.5).
She should have subtracted the difference (x minus 4.5) from Negative 2.
She should have used parentheses to show that Negative 2 is multiplied by (4.5 minus x).

Answers

The errors Emma made from her translation are;

She should have used division to represent the quotient of six and x.

She should have used parentheses to show that Negative 2 is multiplied by (4.5 minus x).

The correct answer choice is option A and E

What errors did Emma make?

quotient of six and a number, x, is the same as negative two times the difference of x and 4.5

6/x = -2 × (4.5 - x)

6/x = -2(4.5 - x)

Ultimately, Emma should have translated the statement in the form 6/x = -2(4.5 - x).
