Answer:
B, or in other words, the last solution is correct.
Step-by-step explanation:
Parallel lines haves the same slope, meaning that Street 2 will have the same slope as Street 1. Street one, according to the graph, has a slope of 1. Thus, Street 2 will have a slope of 1.
By this logic, we can get rid of A and C as choices, as they have a slope of -2 or 2. Now we have choices B and D left.
It can't be B, as the slope is -1, not 1.
Therefore, the answer is D.
Let 
be the number of liters of the 10% solution to be used, and 
the number of liters of the 4% solution. The chemist wants to end up with a 4 liter solution, so
For each liter used in the mixture, a concentration of either 10% or 4% acid will be contributed, and the goal is to make a 4L solution whose concentration is 7%, which means
Solving for 
gives 
, so 2L of both solutions is needed.
Answer:
Scale factor = 1/8
Step-by-step explanation:
The formula would be
Number of miles × scale factor = 5 inches
Number of miles = 40 miles
Hence,
40 miles × scale factor = 5 inches
Scale factor = 5/40
Scale factor = 1/8

<h3>#CARRY ON LEARNING</h3>
Answer:
A. 4/7
Step-by-step explanation:
If Susie has a bag with 9 hairpins, 7 pencils, 2 snacks, and 4 books, the ratio of books to pencils is 4/7 or 4:7.
4 books.
7 pencils.
You could combine the 4 and 7 getting, 4/7 or 4:7
Even though, there are more numbers, the question only asked for the ratio of books to pencils.
