How many different four-letter arrangements can be formed using the six letters A, B, C, D, E and F, if the first letter must be

Ainat [17]

Answer with Step-by-step explanation:

We are given that A,B,C,D,E and F.

We have to find the number of different four -letter arrangements can be formed using given six letters a,if the first letter must be C and one of the other letters must be B and no letter can be used more than once in the arrangement.

Number of letters=6

We have to arrange four letter out of six

After fixing C and B then we choose only two letters out of remaining four letters and repetition is not allowed.

Permutation formula : $nP_r=\frac{n!}{(n-r)!}$

We have n=4 an r=2

Using this formula and substitute the values

Then, we get $4P_2=\frac{4!}{(4-2)!}=\frac{4\times 3\times 2!}{2!}$

$4P_2=4\times 3=12$

Hence, number of different four -letter arrangements can be formed using six letters when repetition is not allowed=12

3. JK Rowling and R.L. Stine are both reading the Hunger Games. J.K. reads 35

Crank

Answer:

Part A:

For J.K. Rowling: 17.5pages/hour

For R.L. Stine: 15pages/hour

Part B:

J.K. Rowling will finish the book first.

Step-by-step explanation:

Part A:

The rate of change in this case represents how much changes a variable in a specific period of time. The variable is the amount of pages.

You have to calculate the amount of pages that J.K. Rowling and R.L. Stine read in one hour.

For J.K. Rowling, 35 pages every 2 hours can be written as:

If you divide 35/2 you can obtain the amount of pages in one hour:

17.5pages/hour (17.5 pages per hour)

For R.L. Stine, 45 pages every 3 hours can be written as:

If you divide 45/3 you can obtain the amount of pages in one hour:

15pages/hour (15 pages per hour)

Part B:

In order to calculate who will finish the hunger games first, you have to calculate the amount of time needed to finish the book.

For J.K. Rowling:

You have to multiply 355 pages by (because in one hour she reads 17.5 pages) to obtain the amount of hours

For R.L. Stine:

You have to multiply 355 pages by (because in one hour he reads 15 pages) to obtain the amount of hours

So, J.K. Rowling will finish the book first because she needs less time than R.L. Stine.

Solve 10-5x+1=7x+11-12

Gekata [30.6K]

Answer:

x=1

Step-by-step explanation:

Let's solve your equation step-by-step.

10−5x+1=7x+11−12

Step 1: Simplify both sides of the equation.

10−5x+1=7x+11−12

10+−5x+1=7x+11+−12

(−5x)+(10+1)=(7x)+(11+−12)(Combine Like Terms)

−5x+11=7x+−1

−5x+11=7x−1

Step 2: Subtract 7x from both sides.

−5x+11−7x=7x−1−7x

−12x+11=−1

Step 3: Subtract 11 from both sides.

−12x+11−11=−1−11

−12x=−12

Step 4: Divide both sides by -12.

−12x

−12

x=1
