Um, ok I'm not entirely sure what number sets you need, but I'll do my best.
Integers: 5, -3, 0, 1, -12
Fractions: 1/2, 4 1/2
Decimals: 14.2, -19.4, 0.125
All of the above can also be considered Rational numbers. Rational numbers are numbers that can be expressed as a fraction. All For example, 14.2 is 14 1/5.
Irrational number:
Pi is irrational. It cannot be expressed as a fraction.
Answer with Step-by-step explanation:
We are given that A,B,C,D,E and F.
We have to find the number of different four -letter arrangements can be formed using given six letters a,if the first letter must be C and one of the other letters must be B and no letter can be used more than once in the arrangement.
Number of letters=6
We have to arrange four letter out of six
After fixing C and B then we choose only two letters out of remaining four letters and repetition is not allowed.
Permutation formula :
We have n=4 an r=2
Using this formula and substitute the values
Then, we get
Hence, number of different four -letter arrangements can be formed using six letters when repetition is not allowed=12
Answer:
Option D
Step-by-step explanation:
Out of all given options, Option D (the parallelogram) will tessellate the easiest.
Option B's shape (the Trapezoid) is also possible. However, it would take a little more work for it to tessellate. The trapezoid provided would not tessellate alone.
Option A and Option C's shape wouldn't tessellate because it would leave a gap. To add, Option C's shape is nearly impossible to tessellate.
