Answer:
-1/3
Step-by-step explanation:
its a math fact i know lol i dont really have steps to solving it
This is the concept of combination. The number of letter-sequence that are possible to be formed from the letters q,u,a,k,e,s will be evaluated as follows:
Total number of letters is 6
Maximum number of letters in a word is 4
thus the number of four letter sequence that can be formed will be:
6C4
=15
The reason why we are using combination is because no letter can be used more than once in each sequence.
Answer:
ted is very smart
Step-by-step explanation:
id do that too lol
Answer:
x = 90 degrees and y = 43 degrees
Step-by-step explanation:
We have an isosceles triangle here, since the length of AB equals the length of AC.
That also means that angle ABC equals angle ACD = 47 degrees.
The sum of the interior angles of a triangle equals 180.
47 + 47 + 2y = 180
94 + 2y = 180
2y = 86
y = 43 degrees
x + 43 + 47 = 180
x + 90 = 180
x = 90
500/100 but 5/1 is simplified
