Answer: B and C
Hope this help :)
Answer:
Step-by-step explanation:
Let the total number of Newspapers be x
Number of newspapers delivered in first hour of his route= 
of x
Total number of newspapers delivered in first hour= x
Number of newspapers left= x-
Number of newspapers left=
Number of newspapers left=
Number of newspapers delivered in second hour=4/5 of
Number of newspapers delivered in second hour=
Fraction of newspapers delivered in second hour is=
Hence, the correct answer is
Answer:
The answers are 
and 
.
Step-by-step explanation:
Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.
First, let's begin with 2:
Then, let's do 5:
Note that we already have 
, so we do not need to include an additional one.
Now, let us do 8:
See how we already have 
, so we won't have to include that as well.
Finally, let's do 20:
Now see that we already have both 
and 
, so we won't have to include both of them, as they are both extras.
Hence, the answers are and .

Answer:
x = y = 22
Step-by-step explanation:
It would help to know your math course. Do you know any calculus? I'll assume not.
Equations
x + y = 44
Max = xy
Solution
y = 44 - x
Max = x (44 - x) Remove the brackets
Max = 44x - x^2 Use the distributive property to take out - 1 on the right.
Max = - (x^2 - 44x ) Complete the square inside the brackets.
Max = - (x^2 - 44x + (44/2)^2 ) + (44 / 2)^2 . You have to understand this step. What you have done is taken 1/2 the x term and squared it. You are trying to complete the square. You must compensate by adding that amount on the end of the equation. You add because of that minus sign outside the brackets. The number inside will be minus when the brackets are removed.
Max = -(x - 22)^2 + 484
The maximum occurs when x = 22. That's because - (x - 22) becomes 0.
If it is not zero it will be minus and that will subtract from 484
x + y = 44
xy = 484
When you solve this, you find that x = y = 22 If you need more detail, let me know.
