Find the number of permutations of the first 8 letters of the alphabet for taking 1 letter at a time?
Answer:
The first 8 letters of the alphabet are:
{A, B, C, D, E, F, G, H}
To find the number of permutations, we can think of 8 positions. In each one of these positions, we can put one of the letters, now we need to find the number of possible options for each one of these positions, the total number of permutations will be equal to the product between all of these options.
Now, taking one letter at a time (to assign at each position)
For the first position, we have 8 options.
For the second position, we have 7 options (because one letter is already taken)
For the third position, we have 6 options (because two letters are already taken, one in the first position and another in the second)
For the fourth position, we have 5 options.
For the fifth position, we have 4 options.
For the sixth position, we have 3 options.
For the seventh position, we have 2 options.
For the last position, we have 1 option.
Then the total number of permutations is:
P = 8*7*6*5*4*3*2*1 = 40,320
which is represented by this model

Suppose you work at a local radio station. You are in charge of a $180 budget for
new tapes and CDs. Record companies will give you 21 promotional (free) CDs. You
can then buy tapes for $8 and CDs for $12.
a. Write a linear inequality that models this situation.
Answer
b. Graph the inequality. Make sure to use proper scales and to label your axes
Answer:
0---22.5 and 21---36
Step-by-step explanation:
you will always have 21 free CDs so you can put a closed circle on 21 then you can have a max of 15 CDs (180/12) soo put another closed circle on 36
now time for tapes, which is easier, the minimum is 0 and the max is 22.5. Now put closed circles on each and you're done. Except that .5 might get you in trouble, use your own discretion on rather to leave it on the .5 or round. I don't know what your teacher is looking for so I will let you decide.

Step-by-step explanation:
Rearrange x=2y-6 to make y the subject.
Answer:
y=0.5x+3
Step-by-step explanation:
So the point of this is to make y the only thing on one side. So first you have to add 6 on both sides. That would make is x+6=2y. Next you need to divide 2 on both sides. That would equal 0.5x+3=y.
Hope this helped!!! :D
The required equation is [tex]y=0.5x+3[/tex].
Given equation is,
[tex]x=2y-6[/tex]
We have to rearrange the equation in terms of y.
Here, [tex]x=2y-6\\[/tex]
Adding 6 to both sides of the equation,
[tex]x+6=2y-6+6[/tex]
[tex]x+6=2y[/tex]
Now dividing the equation by 2 both sides, we get
[tex]\frac{x+6}{2} =y\\[/tex]
[tex]y=0.5x+3[/tex].
Hence the required equation is [tex]y=0.5x+3[/tex].

Two numbers have a sum of 18, and 4 times the first number minus the second number is equal to 17. What is the smallest number?
Answer:
The smallest number is 7
Step-by-step explanation:
Using simultaneous equation;
x+y = 18.....(1)
4x-y = 17.....(2)
from equation (1)..
x+y = 18
y = 18-x...(3)
substitute y into equation (2)
4x-y = 17
4x-(18-x) = 17
4x-18+x = 17
4x+x = 17+18
5x = 35
x = 35÷5
x = 7
substitute x into equation (3)
y = 18-x
y = 18-7
y = 11
Therefore; x=7
y=11
11+7=18
(4×7)-11=17
the smallest number is 7

when you divide a fraction, you use the KCF (keep, change, flip) method so,
[tex]\frac{1}{3}[/tex] ÷ [tex]\frac{2}{1}[/tex]

A diagram of a coin is shown.
10.5 mm
What is the approximate circumference of the coin? Use 3.14 as an estimate for it.
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm
Answer:
66mm
Step-by-step explanation:
A diagram of a coin is shown.
Radius = 10.5 mm
The approximate circumference of the coin is calculated using the formula
2πr
Use 3.14 as an estimate for it.
r = 10.5mm
Hence:
2 × 3.14 × 10.5
= 65.94
Approximately = 66mm
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm

What is the first step in solving the following equation?
28 = -12 - 4x
Answer:
4x = - 12 - 28Step-by-step explanation:
When we transpose - 4x to the LHS then it becomes positive i.e +4x
Now we transpose 28 to the RHS then it becomes negative i.e - 28
So the first step you have to is,
4x = - 12 - 28

A horse runs in a field the speed time graph represents the first 12 seconds of the run after how many seconds had the horse run a distance of 75 metres
Answer:
9.5 seconds
Step-by-step explanation:
0-4 seconds => 20 meters
4-9.5 seconds => 55 meters
total = 75 meters
A horse run a distance of 75 metres in 9.5 seconds.
What is Speed?
The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.
Here, From the graph,
when, t = 4 sec.
distance = 4 X 10 X 1/2
= 20 meters
Now, 75 - 20 = 55 meters
So, 55/10 = 5.5 seconds
Total time = 5.5 + 4
= 9.5 sec.
A horse run a distance of 75 metres in 9.5 seconds.
Thus, A horse run a distance of 75 metres in 9.5 seconds.
