Step-by-step explanation:
The way to solve this is 60mg/1 - ml =
1ml = 1000mg - 60 mg = 940 mg left or .94 ml left or 47/50
one-half average method means there is bonus which is equivalent to over time * half of average hourly rate.
Let us calculate earnings using normal method first.
We are given that 14$ paid for first 40 hours and $11.8 for next 7 hours.
So, net pay would be 14*40+11.8*7 = $642.6
Now we need to find bonus pay using one-half rate method.
That bonus = over time * half of the average hourly rate
Average hourly rate = income earned/total number of hours
=
Hence bonus = 7*= $47.85
Gross pay using one-half average method= net pay + bonus
=642.6+47.85
= 690.45$
So what makes a function a function is that each input (x) only has one output (y).
Set A is not a function because when x = 2, y = -2 and 3.
Set B is not a function because when x = 9, y = 3 and -3.
In short, the correct option is "Neither A nor B".
Answer
Find out the how many birds were at the shelter on Wednesday .
To prove
let us assume that the number of birds be = x
let us assume that the number of cats be = y
As given
An animal shelter spends $3.00 per day to care for each bird and $7.00 per day to care for each cat.
Alexandra noticed that the shelter spent $174.00 caring for birds and cats on Wednesday.
than the equation becomes
3x + 7y = 174
As given
Alexandra found a record showing that there were a total of 34 birds and cats on Wednesday.
than the equation becomes
x + y = 34
Than the two equation are
3x + 7y = 174
and x + y = 34
multiply 3 by x + y = 34 and subracted from 3x + 7y = 174
3x - 3x + 7y - 3y = 174 - 102
4y = 72
y = 18
put in the equation x + y = 34
18 + x = 34
x = 34 - 18
x = 16
The number of birds at the shelter on wednesday is 16 .
