Answer:

The volume of the sphere is 2048 in³.

Step-by-step explanation:

The volume of a sphere is given by:

V = \frac{4}{3}\pi r^{3}

Where:

r: is the radius = 8 in

Having the radius and by using 3 for π, the volume is:

V = \frac{4}{3}*3 (8 in)^{3} = 2048 in^{3}

Therefore, the volume of the sphere is 2048 in³.

I hope it helps you!

Bumek [7]

Answer:

  • Q6. x = 17
  • Q8. Yes, parallel
  • Q9. No, not parallel

Step-by-step explanation:

Q6. Solve for x

<u>Use ratios of similar sides</u>

  • 28/(82 - 28) = (2x + 8)/(5x - 4)
  • 28/54 = (2x + 8)/(5x - 4)
  • 14/27 = (2x + 8)/(5x - 4)
  • 14(5x - 4) = 27(2x + 8)
  • 70x - 56 = 54x + 216
  • 70x - 54x = 56 + 216
  • 16x = 272
  • x = 272/16
  • x = 17

Q8

If ratios are same, the lines are parallel

  • 41.8/33 = (102 - 45)/45
  • 41.8/33 = 57/45
  • 41.8*45 = 33*57
  • 1881 = 1881

Yes, lines are parallel

Q9

  • 38/19 = 52/24
  • 2 = 2 1/3

Incorrect, lines are not parallel

Use the substitution method to solve the system of equations. <br> x+y=11<br> -x=-y-9
allochka39001 [22]
<h2>Answer:</h2>

Like you said, we need to use <u><em>substitution</em></u> to solve for y.

x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10

Now that we've solved for y, we can plug in the number we got into one of the <u><em>original</em></u> equations. (You can choose either equation, but I will use the first one.)

x + 10 = 11\\\\x = 1

Now we have the solution of this system.

(1, 10)

Solve the equation - <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7B5%7D" id="TexFormula1" title="\frac{w}{5}" alt="\frac{w}
Tatiana [17]

Answer:

w = -20

Step-by-step explanation:

-\frac{w}{5} + 9 = 13

Shift the (+9) to the other side of the equation. (+9) will turn into (-9).

-\frac{w}{5} = 13 - 9

   = 4

Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).

-w = 4 × 5

    = 20

Multiply both sides of the equation by (-1) so that -w will turn into w.

w = (-1) × 20

w = -20
