[tex]\sqrt[3]{488+24} \\[/tex]

Answers

Answer:

8

Step-by-step explanation:

First, add the values inside the radical

488+24 = 512

[tex]\sqrt[3]{512}[/tex] = x

This means that: [tex]x^{3}[/tex] = 512

Therefore, x must be equal to 8.

[tex]\sqrt[3]{512}[/tex] = 8

2x - 8x + 1 = 49
this seriously makes no sense

Answers

Answer:

x = -8

Step-by-step explanation:

2x - 8x + 1 = 49

⇒ 2x - 8x = 49 - 1

⇒ -6x = 48

⇒ x = [tex]\frac{48}{-6}[/tex]

       = -8

Answer:

X = -8

Step-by-step explanation:

Add similar elements: 2x-8=6x

-6x+1=49

Subtract 1 from both sides:

-6x+1 -1 =49 - 1

Simplify:

-6x=48

Divide both sides by -6

-6x /-6= 48 /6

Which then gets you the answer up top!

Done the first two but i dont know how to do the mean of it

Answers

I think the answer for the mean is 6.

To get the mean you have to add up the total number of peas in a pod, then divide the amount you added up by how many pods there are. :)

To find mean:

1) Add up all data values to get the sum

2) Count the number of values in your data set

3) Divide the sum by the count

First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.

4 x 2 = 8

5 x 10 = 50

6 x 18 = 108

7 x 14 = 98

8 x 6 = 48

8 + 50 + 108 + 98 + 48 = 312 total number of peas

2 + 10 + 18 + 14 + 6 = 50

312 / 50 = 6.24 peas per pod

So in our example the mean number of peas in a pod is 6.24.

I hope this helps! :)

which expression has a value of 6 when x=2 and y=4?

Answers

B
refer to picture for steps
Answer:6Verification:

Let's verify all the options to the question. Clue given: x = 2, y = 4

Option A:

(x² + 8) ÷ y - 2

=> (2² + 8) ÷ 4 - 2

=> (4 + 8) ÷ 4 - 2

=> 12 ÷ 4 - 2

=> 3 - 2

=> 1 ≠ 6

This answer does not equal 6.

Option B:

(x² + 8) ÷ (y - 2)

=> (2² + 8) ÷ (4 - 2)

=> (4 + 8) ÷ (4 - 2)

=> 12 ÷ 2

=> 6 = 6

This answer is correct as 6 = 6.

Option C:

x² + 8 ÷ (y - 2)

=> 2² + 8 ÷ (4 - 2)

=> 4 + 8 ÷ 2

=> 4 + 4

=> 8 ≠ 6

This answer does not equal 6.

Option D:

x² + 8 ÷ y - 2

=> 4 + 8 ÷ 4 - 2

=> 4 + 2 - 2

=> 4 ≠ 6

This answer does not equal 6.

So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.
