Here we are dealing with combinations without repetitions.
Let's write the form of a name.
For names starting with W:
W _ _ _
For names starting with K:
K _ _ _
We are allowed to use only lettrs from F to X. That's total of 19 letters. We are not allowed to repeat letters so for each letter we can choose from one less available letters.
Let's start with names begining with W. We will write how man possible letters we can choose from.
W 18 17 <span>16
</span>At second possition we can choose from 18 letters because we must not repeat letters and W is placed in front of X in alphabet.
At third position we can choose from 17 letters becasue we already chose two of 19 possible letters.
At fourth position we can choose from 16 letters becasue we already chose three of 19 possible letters.
To calculate total number of possible names we need to multiply these numbers:
1 * 18 * 17 * 16 = 4896
Same calculation can be done for names starting with K. We would get same number as solution.
Total number of possible names starting with W or K is 4896 + 4896 = 9792
1 / (1/6) = x / (2/3)...1 drop to 1/6 dash = x drops to 2/3 dash
cross multiply
(1/6)(x) = (1)(2/3)
1/6x = 2/3
x = 2/3 * 6
x = 12/3 = 4 drops <==
Answer:
1840
Step-by-step explanation:
4 pellets x 4 = 16 pellets
460 pounds x 4 = 1840 pounds
Area: 153.9m
formula: 3.14(r^2)
7^2= 49
3.14•49=153.86
153.86 rounded is 153.9
Answer:
x = -25
x = infinite solutions
Step-by-step explanation for 1:
4(-25) - 10 = 5(-25) + 15
-100 - 10 = -125 + 15
-110 = -110
Step-by-step explanation for 2:
Both equations are the exact same. So whatever number you put, the answer will be right
