Answer:
The number of ways is 13,800 ways
Step-by-step explanation:
In this question, we are tasked with calculating the number of ways to form 3-digits codes from 25 different numbers given that no repetition is allowed.
Now, for the first digit, we have all the 25 numbers completely wanting to take a spot. Now, in how many ways can we choose a single out of 25, that would be 25 ways
Now, we have 24 numbers left, and we are trying to pick one, the number of ways this can be done is 24 ways also
for the last digit, we have 23 numbers and we are selecting just one, the number of ways this can be done is 23 ways too
Thus, the cumulative number of ways would be 25 * 24 * 23 = 13,800 ways
Given the sum:
The sum is given below:
Therefore, the sum of the polynomials is:
We know that
surface area of a sphere=4*pi*r²
volume of a sphere=(4/3)*pi*r³
the ratio surface area to volume
=4*pi*r²/[(4/3)*pi*r³]-----> 3/r----> 3/1080-----> 0.0028
the answer is
the option <span>B. 0.0028 </span>
Well, the largest set it belongs to is the set of all real numbers - numbers which can be written on the number line. -5 is of the set of rational numbers since it can be written as a fraction (-5/1 for example). It is an integer since it is a whole number. Thus:
-5 ∈ <span> ℤ (</span>Integers) ∈ ℚ (Rational Numbers) ∈ <span>ℝ (Real Numbers)</span>
Answer:
8 complete stacks
Step-by-step explanation:
Total magazine = 60
Total books = 42
Each stack will have 7 magazines and 4 books.
Each stack = 7 magazines + 4 books
How many complete stacks of 7 magazines and 4 books can Ms. Martin make?
Number of stack of 7 magazines possible = total magazines / magazines per stack
= 60/7
= 8 4/7
Complete stacks with 7 magazines = 8
Number of stack of 4 books possible = total books / books per stack
= 42/4
= 10 1/2
Complete stacks with 4 books = 10
If 7 magazines on each stacks can make 8 complete stacks
Then, 4 books on each stack can make 8 complete stacks
Note: after 8 stacks using 7 magazines each, magazines will not be available to complete other stacks
