Ответ:
720
Step-by-step explanation:
Given : The word ABSENT
To Find: How many different 6-letter arrangements can be formed using the letters in the word ABSENT, if each letter is used only once?
Solution:
Number of letters in ABSENT = 6
So, No. of arrangements can be formed using the letters in the word ABSENT, if each letter is used only once = 6!
=![6 \times 5 \times 4\times 3 \times 2 \times 1](/tpl/images/0002/1101/28ebd.png)
=![720](/tpl/images/0002/1101/b40b5.png)
So, Option C is true
Hence there are 720 different 6-letter arrangements can be formed using the letters in the word ABSENT.
Ответ:
x=(a+b)/2
"x" is the midsegment (x=19).
"a" and "b" are the bases (a=27).
2. When you clear the second base "b" from the formula x=(a+b)/2 and you substitute the values, you obtain:
x=(a+b)/2
2x=a+b
b=2x-a
b=2(19)-27
b=38-27
b=11
What is the length of the 2nd base of a trapezoid?
The answer is: 11
