Answer:
20
Step-by-step explanation:
Doug and Emily are driving cars on a track, and they both do 20 laps around a 1-mile track. Doug drives an average of 60 miles per hour around the track while Emily drives at an average of 80 miles per hour. When Emily finished her 20 laps how many laps does Doug have left?
Answer:
When Emily finishes 20 laps Doug has to finish 5 laps.
Step-by-step explanation:
To find how many laps does Doug have left, we need to calculate the time that Emily takes to finish 20 laps:
[tex] t = \frac{x}{v} [/tex]
Where:
x: is the distance = 1 mile
t: is the time
v: is the speed of Emily = 80 mi/h
The time that takes Emily to do 20 laps is:
[tex] t = 20*\frac{1 mile}{80 mile/h} = 0.25 h [/tex]
Now, we can find the number of laps:
[tex]x = v*t = 60 miles/h*0.25 h = 15 miles*\frac{1 lap}{1 mile} = 15 laps[/tex]
[tex] laps = 20 - 15 = 5 [/tex]
Therefore, when Emily finishes 20 laps Doug has to finish 5 laps.
I hope it helps you!

What is the slope of the line? Please explain your answer.
A.) m=5
B.) m= -5
C.) m=1/5
D.) m= -1/5
Answer: D
Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5
What is the x and y intercept absolute min/max
x and y-intercept :
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.
Absolute min:
An absolute maximum point is a point where the function obtains its greatest possible value.
Absolute max :
An absolute minimum point is a point where the function obtains its least possible value.
Local Extrema (Local Maxima/Minima): The local maxima and minima on a graph refer to the maximum and minimum points of the graph over a specific interval of the graph as opposed to the entire graph, so there can be multiple local maxima and minima of a given graph.
When considering which points are the absolute maximum and the absolute minimum of a graph, we not only need to consider local extrema (a maximum/minimum of a graph on some interval that contains the point), but we also need to consider the endpoints (the furthest left/right points on our graph). By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.
Step 1: Identify local maxima/minima, as well as the endpoints.
From this graph, we can see that our graph is on the interval
This means we have our endpoints at [-1,-1] , [4,1] ,
to consider. We also observe that we have one local minima and one local maxima in between these points on our interval. The estimated points are all shown in the image.
absolute minimum point : [-1,-1]

Which is a TRUE statement about the transformation shown?
Statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.
We can see that both the figures are identical but the vertices A and C have changed the position.
This shows that it is a reflection of the image given originally as the vertices have only being flipped.
Now, we can also see that the shape and size both are same of the image and the pre-image. Also, the sides of the triangle are equal to one another.
The angles are also equal to one another.
This means that they are congruent to each other.
Therefore, statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.

In 40 minutes; diane walks 2.5 miles and sue walks 1.5 miles. in miles per hour , how much far diane walking?
Diane will walk 1.5 miles more than Sue.
Firstly calculating the speed of Diane and Sue in miles per hour. As per the known fact, 1 hour has 60 minutes.
In 40 minutes Diane walks distance = 2.5 miles
So, converting speed in miles per hour = (2.5 ÷ 40)×60
Speed of Diane in miles per hour = 3.75 miles per hour
In 40 minutes Sue walks distance = 1.5 miles
So, converting speed in miles per hour = (1.5 ÷ 40)×60
Speed of Sue in miles per hour = 2.25 miles per hour
Difference between the distance covered = 3.75 - 2.25
Performing subtraction
Difference between the distance covered = 1.5 miles
Hence, Diane will walk 1.5 miles more than Sue.

The Johnson party had a good hunt. They bagged a total of 26 deer which included some

little bucks. The number of big bucks was half as many as little bucks. How many big bucks,
little bucks and does did the party get?
9514 1404 393
Answer:
3 big bucks6 little bucks17 doesStep-by-step explanation:
Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.
B + L + D = 26 . . . . . . total bagged
D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks
B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks
__
We can substitute for B and D in the first equation:
L/2 + L + (5 +2L) = 26
7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms
L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7
D = 5 + 2·6 = 17
B = 6/2 = 3
The party bagged 3 big bucks, 6 little bucks and 17 does.
how to solve christina used 2 1 3 gallons of gas to drive her car 64 1 6 miles. what was the fuel efficiency of her car, in miles per gallon, for the trip? miles per gallon
The efficiency of car is 55/2 MPG
• Fuel efficiency is a measure of how much energy in terms of fuel will be converted to kinetic energy to travel by a car. Most nations use miles per gallon to measure fuel efficiency (mpg).
• A good rule for fuel efficiency is that at least you are getting 23 miles per gallon combined city and highway.
• We calculate fuel efficiency by the formula MPG = (No of miles drove since last fill) / Gallons Based on the given conditions, Formula for MPG = (64 1/6 ) / (2 1/3)
Solving this we get= (64 + 1/6 ) / ( 2 + 1/3)= ((384 + 1)/6) / (7/3) = (385/6) / (7/3)= 55/2
Therefore, the vehicle's efficiency is 55/2 MPG.
