Answer:
The first digit of a two digit number can be any of digits 1 - 9. It cannot be 0 though. Therefore there are 9 possible digits for the first place.
There are 5 possible digits for the second position. The two digit number has to be odd and therefore the final digit must be 1,3,5,7 or 9
Therefore for each and every one of the nine first digits there are 5 digits that the second can be.
Therefore ANSWER = 9 * 5 = 45 possible permutations.
2. The largest two digit number = 99
Subtract 57 and you get 42
ANSWER = 42
The forty two numbers are 58 ,59, 60, 61......98, 99
The domain is
{x | x >=0}
Or simply [0, infinity)
Since Haley can not use any negative minutes.
The range is
{y | y >=20}
Or simply [20, infinity)
This is because if Haley doesn't use any minutes, the price will stay at $20.
Let me know if you have any questions.
Answer:
£288150
Step-by-step explanation:
We'll use the formula
PRT/100= interest
But in this case we are looking for principal P
Rate= 2%
Interest= £5763
T=1
P= (I*100)/(RT)
P= (5763*100)/(2*1)
P= 288150
The principal is £288150
I believe it’s 5xy since all the numbers are factors of five and since each number contains the variables xy.
