You must calculate how many ways can 2 people be selected from 65.
The formula is:
n! / r! * (n-r)! =
65! / 2! * 63! =
65*64*63! / 2 * 63! =
65*64 / 2 =
2,080 handshakes

A small cube has the volume shown. Its side length is 1.5 in less than a second larger cube. What is
eduard

The volume of the larger cube is 227 inches cube.

<h3 /><h3 /><h3>Volume of a cube is describe below:</h3>
  • v = L³

where

L = length

The small cube has the following volume:

  • v = 95 in³

Let

The side length of the small cube = x

Therefore,

95 = x³

x = ∛95

x = 4.56290264

x ≈ 4.6

Its side length is 1.5 inches less than a second larger cube. Therefore,

  • length of larger length cube = (x + 1.5 )inches = 4.6 + 1.5 = 6.1 inches

Therefore, the volume of the larger cube can be found as follows:

Volume = 6.1³

volume = 226.981

volume ≈ 227 inches³

Write the equation of a line that is perpendicular to y=-0.3x+6 and passes through the point (3,-8)
astraxan [27]

Answer:

y = 10/3x - 18

Step-by-step explanation:

1. Take the reciprocal of the slope given to you, 3/10 -> 10/3

2. Write your new equation with the new slope in slope-intercept form: y=10/3x+b

3. Use the point given to find your y-intercept / b: -8 = (10/3)(3)+b

-8 = 10 + b

-18 = b

4. Plug b back into your new equation. y = 10/3x - 18
