<h3>
Answer:</h3>
All are rational.
<h3>
Step-by-step explanation:</h3>
Any number you can write exactly and completely, or any repeating decimal is a rational number. Any number that can only be written exactly using a symbol, such as π or √2, is an irrational number. Something like √6.25 is rational, because it can be written exactly as 2.5, without the symbol.
The idea of "rational" means the number can be expressed as the ratio of two integers. Any integer can be expressed as the ratio of itself and 1.
All of your numbers can be expressed as the ratio of integers:
... -0.45 = -45/100 . . . . any terminating decimal can be expressed as a ratio of integers by making use of the place value multipliers
... 5/12 . . . . is the ratio of integers
... 0 = 0/1
... 247 = 247/1
Answer:
v^32
Step-by-step explanation:
-4x-8=32
since it is a negative times a negative it becomes a positive
Answer:
There are 64,000 possible codes. Jillian is incorrect, since he added the possible options in each trial, instead of multiplied them(he did 40+40+40 instead of 40*40*40).
Step-by-step explanation:
From 0 to 39, there are 40 numbers.
The code has three values:
V1 - V2 - V3
When we have n trials with m possible options, the total number of opitons is:
In this question:
3 trials(values), with 40 options. So
There are 64,000 possible codes. Jillian is incorrect, since he added the possible options in each trial, instead of multiplied them(he did 40+40+40 instead of 40*40*40).
