Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.
in a three digit number, the hundreds digit is one more than the ones digit and the tens digit is twice the hundreds digit. If the sum of the digits is 11, find the number. If the hundreds digit of the number is x, the equation will be? 20 Points to solve and brainliest.
Answer:
I am not sure, but I think 362 is the answer
Step-by-step explanation:
hundred digit:x
tens digit:2x
ones digit:x-1
x+2x+x-1=11
4x=12
x=3
number=362

find surface area of the square pyramid!!! pls i need help with explaining!!!!!
Answer:
39 square yards
Step-by-step explanation:
The base is a square, so the area is 3 x 3 = 9.
Each side is a triangle, and the formula for that is (1/2)(base)(height)
The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30
Add the base and sides
30 + 9 = 39
Answer:
39 yards
Step-by-step explanation:
surface area = A + [tex]\frac{1}{2}[/tex] ps
A = area of the base
p = perimeter of the base
s = slant height
the base of the pyramid is a square, all sides and angles are equal
; 3 yards
; area of a square = l x w
; area of the base = 9 yd (A)
perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)
slant height = 5 yd (s)
; sub it into the formula
surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5
surface area = 39 yd

Step-by-step explanation:
b
Answer:
A
Step-by-step explanation:
i did the math and it took forever please mark brainliest :)
Example Given
Find a or b
a = 20. b = ? c = 25
Find b or a. c^2 - a^2 = b^2
25^2 - 20^2 = c^2
625 - 400 = 225
Square Root of 225 is 15

absolute value is the oppistie of the number so if it is positive is will turn negative so i think the answer is C
If an impulse travels 100 m/s, about how long will it take the impulse to travel 10 meters?
Answer:
0.1 seconds
Step-by-step explanation:
10/100=0.1
Answer:
1/10th of a second or .1seconds
Step-by-step explanation:
100m/s meaning its traveling 100 meters a second.
Since its going to travel 10 meters, it will take 1/10 the time since 10/100 = 1/10
The time is in seconds so it will take them 1/10th of a second.
Hey PLZZZZ HELP!
The profits earned in a year by some companies in a city are shown below: Company Profit A $160,000 B $140,000 C $130,000 D $1,120,000 E $150,000 Based on the data, should the mean or the median be used to make an inference about the profits earned by these companies? Mean, because it is in the center of the data Median, because it is in the center of the data Mean, because there are no outliers that affect the mean Median, because there is an outlier that affects the mean
Answer:
mean because there is an outlier
Step-by-step explanation:
since there is an outlier that affected the mean which is company D, it can only be mean because the outlier is too big.
I NEED THIS ASAP!!!!!!!!
Answer:
A
Step-by-step explanation:
A: -a/-b=c (negative number divided by negative number is positive number A is correct)
B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)
C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)
D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)
How do I solve this?
Answer:
We know the width maybe 22ft and at its widest.
IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides

Step-by-step explanation: so the area of the triangle is 150 the area of the garden is 50 so he wants them in the triangle not the garden so 150 - 50 is 100 and each bag of rocks will cover 2.5 so 1-- divided by 2.5 is 40
A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet

helpppp plzzz...plz give steps
Answer:
Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]
Therefore value of r=3 inches
