<h3>What is permutation?</h3>

The formula for permutation is given as:

Permutation = \frac{n!}{n - r!}

Where:

  • n is the total number of objects = 9
  • r is the number selected = 3

Substitute into the formula

Permutation = \frac{9!}{9 - 3!}

P( 9, 3) = \frac{9!}{6!}

P( 9, 3) = \frac{362880}{720}

P( 9, 3) = 504 ways

Thus, the number of ways of she can do it is 504 ways

What percent of the surface area of the ottoman is green not including the bottom .The radius of the ottoman is 22 in and the cu
max2010maxim [7]

Answer:

37%

Step-by-step explanation:

Surface area of a cylinder = πr² + 2πrh

With r = 22 and h = (6 + 10) = 16

Area = π * 22² + 2 * π * 22 * 16

Area = 1520.728 + 2211.968

Area = 3732.696 in²

Percentage of green = surface area of green ÷ total surface area

Surface area of green = 2πrh

Surface area of green = 2 * π * 22 * 10

Surface area of green = 1382.48

Percentage of green = 1382.48 / 3732.696 * 100%

Percentage of green = 37%

calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP
qaws [65]
∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\  \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2
