Answer:
y = 15x + 20
Step-by-step explanation:
He charges a flat rate of $20, so any total for hours worked will have an additional $20 added to it.
The 15x represents his earnings per hour. He makes 15 per every hour worked, x represents the number of hours worked
The answer is 15/100 x 45 =6.75 minutes <span />
This is a problem of Permutations. We have 3 cases depending on the number of B's. Since no more than three B's can be used we can use either one, two or three B's at a time.
Case 1: Five A's and One B
Total number of letters = 6
Total number of words possible =
Case 2: Five A's and Two B's
Total number of letters = 7
Total number of words possible =
Case 3: Five A's and Three B's
Total number of letters = 8
Total number of words possible =
Total number of possible words will be the sum of all three cases.
Therefore, the total number of words that can be written using exactly five A's and no more than three B's (and no other letters) are 6 + 21 + 56 = 83
Answer:
In M/n(x) x cannot be 0
Step-by-step explanation:
If any number is divided by 0, then that number is undefined and has no answer, so in math this is always avoided by not dividing with 0.
First we are going to start by subtracting 3-10 and that gives us 7 so then you divide 7 by 4”3 and you get 2.3
