Answer:

5040

Step-by-step explanation:

This problem is about indistinguishable permutation. We have indistinguishable objects, in this case, these are the letter of the word ELLIPSES. The permutations for the word ELLIPSES is the same when you swap the places of the Ls. We need to not count them to avoid double counting.

We first count how many letters we have on the word, and then count the repeating letters.

ELLIPSES has 8 letters, 2 Es, 2Ls, and 2S.

The formula for indistinguishable permutation is

where n is the total number of objects and  are the number of indistinguishable objects.

We have 2Es, 2Ls, and 2S; the formula then becomes:

Simplifying gives us

There are 5,040 distinguishable permutations of the word ELLIPSES.

The total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.

The given word is ELLIPSES.

It is required to find total distinguishable permutations that are possible with the above word.

A permutation can be defined as the number of ways a set can be arranged.

Permutation formula as below:

[tex]P=\frac{n!}{p!q!r!...}[/tex]

Where n = Total number of objects.

     p,q,r...= the number of indistinguishable objects.

Here total number of letters in the word n = 8

and ELLIPSES have 2Es, 2Ls, and 2S; the formula then becomes:

[tex]=\frac{8!}{2!2!2!}[/tex]

[tex]=\frac{8*7*6*5*4*3*2*1}{2*1*2*1*2*1}[/tex]

[tex]=5040[/tex]

Thus, the total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.

Step-by-step explanation:

The perimeter is the sum of all sides.

AB+AC+CB=75

(2x-9) + (2x+3) + (3x+4) = 75

Combine like terms:

(2x+2x+3x) + (-9+3+4) = 75

7x - 2 = 75

7x = 77

x=11

Replace 'x' with '11' in the above equations to find that:

AB = 2(11) - 9 = 22 - 9 = 13 m

AC = 2(11) + 3 = 22 + 3 = 25 m

CB = 3(11) + 4 = 33 + 4 = 37 m

13 + 25 + 37 = 75 m

We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:

[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]

The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:

[tex]y=-\frac{3}{2}x+3.[/tex]

Answer: (5,18); (-5,38)

Step-by-step explanation:

x^2-2x+3=-2x+28

x^2-25=0

(x-5)(x+5)= 0

-2(5)+28= 18

-2(-5)+28=38

(5,18)(-5,38)

Answer:

5

Step-by-step explanation:

Answer:

B. 4x+5

Step-by-step explanation:

First, you multiply both sides by 4, then you have x=y-5. You then add 5 to get 4x+5

(in the very beginning, you switch the x and y so you would have to make the equation x= y-5 / 4 if that confused you)

Answer:

tan A = ± 1/√3 or ± 0.58

Step-by-step explanation:

2 ways to solve this question.

1. cos 2A = 1/2       2A = 60° or 300° or 420° or ....

   A = 30° or 150° or 210° ....

  tan A = tan 30° or tan 150° or ... = ± 1/√3

2. cos 2A = 2 cos²A - 1        1/2 = 2 cos²A - 1     cos²A = 3/4

   cos 2A = 1 - 2 sin²A         1/2 = 1 - 2 sin²A       sin²A = 1/4

   tan²A = sin²a/cos²A = (1/4) / (3/4) = 1/3

   tan A = ± 1/√3 or ± 0.58

Answer: 1/2 times 6x equals 3x  and then you do 1/2 times 4 and that equals 2 then multiply the 3 and 4 in the parenthesis and that is 12 then add 12 to the 3 and 2 and your answer is 17.

Answer:

Volume of given figure = 113.12 cm²

Step-by-step explanation:

Given:

Radius of cylinder = 4/2 = 2cm

Radius of cone = 4/2 = 2 cm

Height of cylinder = 7 cm

Height of cone = 6 cm

Find:

Volume of given figure

Computation:

Volume of given figure = Volume of cylinder + Volume of cone

Volume of given figure = πr²h + (1/3)πr²h

Volume of given figure = (22/7)(2)²(7) + (1/3)(22/7)(2)²(6)

Volume of given figure = (22/7)(4)(7) + (1/3)(22/7)(4)(6)

Volume of given figure = (22)(4) + (22/7)(4)(2)

Volume of given figure = 88 + 25.14

Volume of given figure = 113.12 cm²

Answer:

Depth is 4 feet.

Step-by-step explanation:

Given:

Length of an aquarium is 2.3 feet

Width of an aquarium is 1.2 feet

Volume of an an aquarium is 11.04 cubic feet

To find: depth of an aquarium is 2.3 feet

Solution:

If [tex]l,b,h[/tex] denote length, width and height of a cuboid then volume (V) of a cuboid is equal to [tex]lbh[/tex]

[tex]l=2.3[/tex] feet

[tex]b=1.2[/tex] feet

[tex]V=11.04[/tex] cubic feet

[tex]11.04=2.3(1.2)h\\h=\frac{11.04}{2.3(1.2)}\\h=\frac{11.04}{2.76}[/tex]

[tex]h=4[/tex] feet

Therefore,

depth is 4 feet.

Answer: 480 in.

Step-by-step explanation:

Given

The width of the sandbox is 48 in.

The length of the sandbox is four times the width

[tex]\therefore L=4\times 48=192\ in.[/tex]

Perimeter is the sum of the sides of the shape

The perimeter of the box is

[tex]P=2[48+192]=480\ in.[/tex]

Answer:

the  perimeter of the sandbox is 480 inches

Step-by-step explanation:

The computation of the perimeter of the sandbox is shown below:

Since the width is 48 inches

And, the length would be four times the width i.e.

= 4 × 48

= 192 inches

Now the perimeter of the sandbox is

= 2( length + width)

= 2 (192 inches + 48 inches)

= 480 inches

Hence, the  perimeter of the sandbox is 480 inches
