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
9.99*4=39.96
39.96*.20=7.992 39.96-7.992=31.968
31.968*.0675=2.1578 31.968+2.1578=
$34.13
Answer:
4 inches
Step-by-step explanation:
40/24=10/6
40/10=4
24/6=4
(40/24)/(4/4)=10/6
(10/6)(4/4)=10/24
Answer:
OK so:20 on average
Step-by-step explanation:
7.5 divided by 1.5=5 so you walk an average of 5 meters in 1 min
4*5=20
Answer: the formula is (A=bh1/2)
Step-by-step explanation: #4 (The triangle)
First let’s find the base length of the triangle.
28 - 16 = 12
Ok now let’s do the real math now
Area = bh1/2
Area = (12)(16)(1/2)
Area = 96
Don’t worry about the slant height it’s just there to trick you
