Divide the total price by the total number of books from each printer to find the price per book:
Printer A: $350 / 100 books = $3.50 per book
Printer B: $150 / 40 books = $3.75
Printer A has the lowest price.
Answer:
t = 11 min
and
t = 18 min
Step-by-step explanation:
When we have unidimensional motion, the sign of the velocity defines the direction.
So we could say that a positive velocity like:
v = 4ft/min
Means that you are moving to the right with a speed of 4 feet per minute.
And a negative velocity like:
v = -3 ft/min
means that you are moving to the left with a speed of 3 feet per minute.
Then the bug changes direction when the velocity changes of sign.
In the graph, we can see that the velocity changes of sing in two points, these points are:
t = 11 min
and
t = 18 min
Answer: x = 35
Step-by-step explanation: 2x+110=180
2x+110-110=180-110
2x=70
2x/2=70/2
X=35
Answer:
slope is -1
Step-by-step explanation:
Slope of the line is changes in y over changes in x. It can also be referred as rise over run.
We can express mathematically as:
where m is slope.
Let (-2,5) be
and (6,-3) be
. Hence, apply the slope formula:

Therefore, the slope is -1
15/50 if the problem needs to be out of fiftieths, then you multiply the denominator (10) by 5 to get 50, so you do the same to the numerator to get your answer
