How many ways can six of the letters of the word 'PALINDROME' be selected and written in a row if the first two letters must be

IgorC [24]

BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

According to the statement

we have given that the word 'PALINDROME' and we have to find that the in how much ways this word can be arranged.

So, For this purpose, we use the permutation here

So, A permutation is a mathematical technique that determines the number of possible arrangements.

The word given is:

'PALINDROME' this contain 10 words and given 2 words M and E are in any order.

So, Permutation takes place with $P^{10} _{2}$ .

So,

$P^{10} _{2}$

Now solve this then

$P^{10} _{2} = \frac{10!}{(10 -2) !}$

And

$P^{10} _{2} = \frac{10!}{(8) !}$

$P^{10} _{2} = \frac{10*9*8*7*6*5*4*3*2*1}{(8*7*6*5*4*3*2*1) !}$

And then after take common from them and cancel it the equation become

$P^{10} _{2} = 10*9$

$P^{10} _{2} = 90$

90 ways are comes as the output.

So, BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

An object is 3.6 m from the pinhole. Its image is 4.2 cm from the opposite side of the pinhole. The height of the image is 0.8 c

madreJ [45]

Answer:

Height of the object is 68.6 cm.

Step-by-step explanation:

The height of the object can be determined by:

$\frac{object distance from pinhole}{image distance from pinhole}$ = $\frac{object height}{image height}$

From the given question;

object distance from pinhole = 3.6 m = 360 cm

image distance from pinhole = 4.2 cm

height of image = 0.8 cm

So that;

$\frac{360}{4.2}$ = $\frac{object height}{0.8}$

⇒ object height = $\frac{360*0.8}{4.2}$

= $\frac{288}{4.2}$

= 68.571

object height = 68.6 cm

Thus, the height of the object is 68.6 cm.

Need help gotta turn in in 20 minutes!!!1

Answer:

$\huge\boxed{Answer\hookleftarrow}$

From the figure we can see that, $\large\bold{3x°}$ & $\large\bold{x + 30°}$ are vertically opposite angles.

⎆ <u>Vertically opposite angles are equal to each other.</u>

So, equation ⇻ $\large\bold{3x° = x + 30°}$

____________________

Value of x will be :-

$3x° = x + 30° \\ 3x - x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ x = 15$

Write in detail how you have used math in the real-world to solve a problem.

neonofarm [45]

Answer:

I went shopping once for ingredients of a cake, but i didn't know what my finale price would be. So i estimated what the total cost could be, then i took all the prices and added them up then divided the price by how many ingredients i got to find the average and it was pretty close to my estimate. So math can help when you go shopping. (Sorry if how i find my prices is weird, i kinda just stand in one spot for at least 5 - 8 mins trying to find my price)
