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.

Which equation calculates the number of 1313-cup servings you can make with 4 cups of pudding?

yuradex [85]

D is the correct answer partly because it's the only equation that has the correct outcome and partly because you have to divide 1313 by 4 anyways for the answer to make sense.
number of cups you have ÷ number of cups per serving = number of servings

(1) 4p²q : 10pq²

tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

$=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}$

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

$2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}$

Now, 9 months : 2½ years = $\dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}$

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = $\dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}$

Hence, Simplified ratio of 5 m : 600 cm is 5:6.

Any help to solve this problem. Provide steps. Thnx

Alekssandra [29.7K]

Answer:

284cm^2

Step-by-step explanation:

first, we split up the shape into seperate sections that we can easily find the areas of.

i will draw vertical lines in the bottom left and right, leaving me with 2 seperate rectangles and 1 irregular pentagon.

we know that these rectangles are 4x8cm, so we do 4 * 8 which gives us 32.

there are 2 of these, so 32 x 2 = 64cm^2.

now, i chose to seperarte the pentagon into a rectangle and a triangle,

and i found the height and width of the rectangle to be (18 - (4+4)) x (8+7), or 10 x 15.

the area of the rectangle is 150cm^2.

now, for the triangle.

the line through the centre of th shape is 22cm long, but we only want the part in the triangle. luckily, there are mesurements that can help us with this.

8 + 7 = 15.

22 - 15 = 7.

now we know that the height of the triangle is 7 cm.

from earlier, we also know the base, which is 10cm.

7 x 10 = 70cm^2.

now we add all these together:

70 + 150 + 64 = 284cm^2
