Which of the following cannot be solved using nPr?
permutations of the letters of the word "OF"
permutations of the letters of the word "PERMUTATION"
permutations of the letters of the word "THINGS"
permutations of the letters of the word "N"
Answer:
permutations of the letters of the word "PERMUTATION"
Step-by-step explanation:
The number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr. The correct answer is B.
What is the permutation?The permutation is defined as considered an ordered combination.
The following formula computes the permutation of r items from n:
P(n, r) = n! /(n-r)!
here order matters and repetition is not allowed.
Therefore, nPr cannot be used to solve problems that involve repeating items or where order does not matter.
As per the question, the permutations of the letters of the word "OF", "THINGS", and "N" involve distinct letters and no repetition, so they can be solved using nPr.
However, the word "PERMUTATION" has repeated letters.
Therefore, the number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr because it does not account for repeated items.

simplify (a^-2b^2/a^2b^-1)^-3
Answer:
[tex]\frac{a12}{b3}[/tex]
Step-by-step explanation:
Hope this is right and helps you!
Answer:
a^12/b^9
Step-by-step explanation:
You need to multiply the exponent -3 to every other exponent
So then you would end up with a^6b^-6/a^-6b^3
Now you need to flip the negative exponents to the other side which would be a^12/b^9

Rewrite the equation using the same base.
Solve for x. Write your answer in simplest form
Answer:
x = 5
Step-by-step explanation:
2⁴(2x) = 2⁵(x + 3)
2^8× = 2^5x + 15
cancel out the 2
8x = 5x + 15
8x - 5x = 15
3x = 15
divide through by 3
x = 5

To make a jug of plant fertilizer, Malaika uses 6 cups of water and 3 scoops of fertilizer. Bart uses 8 cups of water and 5 scoops of fertilizer. Will Malaika's and Bart's plant fertilizer have the same strength? Explain.
Answer:
No they will no have the same strength. So what I did was find a common number between them so between 8 and 6 they both can be multiplied to 24. So 6 goes into 24 4 times so I multiplied 3 times 6 and then 8 goes into 24 3 times so I multiplied 3 and 5 and so the final answer is that bart has more strong fertilizer
Step-by-step explanation:
6*4=24 4*3=12
8*3=24 5*3=15

The area of the figure is ___ square units.
Answer:
26 square units
Step-by-step explanation:
We are given a diagram and are asked to find the area of the figure in square units.
To solve, take in mind that we need to multiply the sides given.
Area is L * W, therefore, we know that our length is 5 by 2 units, while our width is 3 by 2 units.
First start with the length, since it is 5 by 2 we multiply 5 and 2 :
5 * 2 = 10
Then with the width, since it is 3 by 2, we can multiply 3 and 2 :
3 * 2 = 6
Then do the length again since the bottom part of the diagram needs to be included, it is also 5 by 2 :
5 * 2 = 10
Add all these together to get your answer :
10 + 6 + 10
16 + 10
26 square units.

What is the volume of the composite solid? 6 m 4 m 3 m 4 m 4 m
Answer:
Please read explanation
Step-by-step explanation:
A picture would be helpful, but I think the answer might be (6x4x3)+(3x4x4). If your shape is made up of many parts, you should find the volume of each shape then add them up to find the total volume. (To find volume, multiply base x height x width) If you could give a picture, it would be very helpful because I don't really know which numbers I should multiply to find volume. I hope this explanation helps, and please comment if you need to ask me anything.
