What type of number is<br> -4 pi

A keycode must contain 2 letters and 3 numbers. The letters may be any letter of the alphabet. The numbers should be any number

OverLord2011 [107]

The English alphabet contains 26 letters (a, b, c, ...y, z).

The digits from 0 to 9 are a total of 10.

A keycode contains 2 letters, and 3 numbers, for example:

AB 598; MM 139; NT 498; ...

So there are 26 possible choices for the first letter, which can combined with any of the 26 possible choices for the second letter, so there are a total of

26*26=676 possible pairs of letters.

Similarly, the 10 possible choices for the first number, which can be combined with the 10 possible choices for the second number, and the 10 possible choices for the third number make a total of :

10*10*10=1,000 possible triples of numbers.

Any of the 676 possible pairs of letters can be combined with any of the possible 1,000 triples of numbers. This makes a total of

676*1,000=676,000 keycodes.

A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up,

Marianna [84]

Answer:

C. 92 degrees

Step-by-step explanation:

Given that the $\angle{wxy}=$ 92° which is one of the angles of the quadrilateral WXYZ

The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.

The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.

So, $\angle{w'x'y'}= \angle{wxy}$
