Elena L [17]3 years ago
7 0

Answer:

Number of total arrangement of beads = 2,520

Step-by-step explanation:

Given:

Number of beads in necklace = 8 beads

Find:

Number of total arrangement of beads

Computation:

Changing beads is a cyclic permutation,

So,

Formula to find number of total arrangement in cyclic permutation

(n-1)!/2 , where n = number of item

So,

(n-1)!/2

Number of total arrangement of beads = (8-1)!/2

Number of total arrangement of beads = (7)!/2

Number of total arrangement of beads = (7 x 6 x 5 x 4 x 3 x 2 x 1) / 2

Number of total arrangement of beads = 5,040 / 2

Number of total arrangement of beads = 2,520

If your yard is 6 feet wide and requires 96 pieces of sod that are cut into 1 foot squares, how long is it?
satela [25.4K]
Is the answer 44 feet wide? What I did was draw a rectangle an label both widths as 6, that equals 12. Then I subtracted 12 from 96 and got 84 and in order to only get one side length I divided it by 2 and got 42. Next I added 2 to that because the width of one side took up one foot and so did the other side so yeah. I'm just guessing.

HELLP!!!!!!!!!! I’ll mark you the brainiest
anastassius [24]

Answer:

n ≥ -3

Step-by-step explanation:

So, divide -27 by 9n and the answer to that is -3, because when you're dividing a negative number and a positive, the answer would always be negative.

This sign : ≥ means greater than or equal to, and because we are solving for n, -3 is equal to n.

What will be the units of the square of the following <br>a - 2346<br>b - 5677​
AlladinOne [14]
<h2>Answer:</h2>

(a) 6

(b) 9

<h2>Step-by-step explanation:</h2>

The units of a whole number is the rightmost digit in the number. For example, if the number is <em>15678</em>, the units is <em>8</em> since that is the rightmost digit. Another example is <em>25795</em>. The units is <em>5.</em>

<em></em>

(a) To find the units of the square of -2346,

<em>i. First find the square of (-2346)</em>

(-2346)² = (-2346) x (-2346) = 5503716

<em>ii. Now find the rightmost digit.</em>

The rightmost digit of 5503716 is 6.

<em>Therefore, the units of the square of (-2346) is </em><em>6</em>

<em />

<em />

(b) To find the units of the square of -5677,

<em>i. First find the square of (-5677)</em>

(-5677)² = (-5677) x (-5677) = 32228329

<em>ii. Now find the rightmost digit.</em>

The rightmost digit of 32228329 is 9.

<em>Therefore, the units of the square of (-5677) is </em><em>9</em>

<em />

<em />

Help<br>question on the image.​
Simora [160]

Answer:

  no

Step-by-step explanation:

We want to compare the pot holder hole dimension to the pot dimension. The hole diameter is the overall pot holder diameter less the wall thickness on either side:

  hole diameter = (20 1/5) -2(1 2/7) = 20 -2(1) +1/5 -(2)(2/7)

  = 18 +(1/5 -4/7) = 18 +(7 -20)/35 = 18 -13/35

  = 17 22/35 . . . . cm

We want to compare this to 17 4/5. We can do that by using a common denominator for the fractions.

  17 4/5 = 17 + (4/5)(7/7) = 17 28/35 . . . . cm

The pot has a diameter of 17 28/35 cm; the pot holder has a hole diameter of 17 22/35 cm, so <em>the hole is smaller than the pot</em>.

The pot will not fit into the plant pot holder.

_____

You can use your calculator to find the free space around the pot by computing ...

  20 1/5 -2(1 2/7) -17 4/5 = free space = -6/35 . . . . cm

Negative space means the pot is larger than the hole.

nata0808 [166]

Answer: Expression for the amount raised by Rachel = x

Expression for the amount raised by Francesca = x+10.50

Step-by-step explanation:

Let x = the amount raised by Kayla.

Since Rachel and Kayla each raised the same amount.

then, expression for the amount raised by Rachel = x

Francesca raised $10.50 more than each of them.

Then, expression for the amount raised by Francesca = x+10.50
