It will take both of them 2 11/12 hours to complete the room
<h3>Fractions and proportions</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction.
Let the time it will take them to complete the job together be "x" such that;
1/x = 1/5 + 1/7
Simplify
1/x = 7+5/35
1/x = 12/35
Cross multiply
12x = 35
x = 35/12
x = 2 11/12 hours
Therefore it will take both of them 2 11/12 hours to complete the room

The required ratio is give by $40/m, 4 miles/min, 30 mile/liter. .
Let, just assume a vehicle is given an economy of $280 of 7m.
<h3>
What is the Ratio?</h3>
The ratio can be defined as the comparison of the fraction of one quantity towards others. E.g.- water in milk.
Now,
The ratio can be given as for economy = 280/7
= $40/m
here for new values,
suppose the vehicle travel for 40miles in 10 mins
ratio = 40/10= 4 miles/min
and vehicle consumes 2 liter fuel on 60 miles of distance ratio can be given as
ratio = 60/2 = 30 mile/liter.
Thus the required ratios can be given as $40/m, 4 miles/min, 30 mile/liter.

Because the three numbers are consecutive, if the first one is x, the second should be x+1, and the third one is x+2
the three numbers add up to be 5982, so
x+(x+1)+(x+2)=5982
3x+3=5982
3x=5979
x=1993
1993,1994,1995

Answer:
see the attachment for the graph
Step-by-step explanation:
Since all you want is the graph, it is convenient to use a graphing program to produce it.
__
You will notice that the point on the circle is 4 units over and 3 units up from the center.* This tells you the square of the radius is 4²+3² = 25. You only need to know this if you're using a graphing calculator to plot the equation ...
(x +4)^2 +(y -1)^2 = 25
If you're graphing this by hand, you can set your compass to the distance between the plotted points, as we have done in our graphing program.
_____
* Hopefully, you recognize these (4 and 3) as the legs of a 3-4-5 right triangle, so you know immediately that the radius is 5. Even if you don't, you can figure it using the Pythagorean theorem, as we have done above.
__
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
