Distance from New Orleans to Boston and back is the same.
t - time from New Orleans to Boston
(t-1) - time from Boston to New Orleans
40t - distance between New Orleans and Boston.
80(t-1) - distance between Boston and New Orleans.
40t = 80(t-1)
40t = 80t - 80
40t = 80
t=2 h
To find average speed we need to find all distance and divide it at all time.
All distance = 40t +80(t-1) = 120t - 80
All time = t+(t-1)= 2t-1
Average speed =(120t - 80)/(2t-1)
Now we can substitute t=2.
Average speed =(120*2 - 80)/(2*2-1)=53.33 m/s

All you have to do is divide 6 by 5.
Answer:
If the kid walks for the dotted line, the distance is 36ft.
Now, you can see that this is a triangle rectangle, then we must have that:
x^2 + (x + 6)^2 = 36^2 (the Pythagorean theorem)
Now we must solve this for x.
x^2 + x^2 + 2*6*x + 36 = 36^2
2*x^2 + 12*x -1260 = 0
The solutions for this equation are:
the solutions are:
x = (-12 - 101.1)/4 = -28.78
x = (-12 + 101.1)/4 = 22.3
Then we have x = 22.3 ft
The lenght of the path following the cathetus is:
D = x + x + 6 = 2*22.3ft + 6ft = 50.6ft
Then the difference between the distances is:
Diff = 50.6ft -36ft = 14.6ft
Answer:
123m squared
Step-by-step explanation:
First let's get the area of the square by doing 10*10 to get 100, now let's find the area of the semicircle. We can pretend it is a full circle and then cut it in half. We do the radius which is 5 times, pi which is 3.14 to get 15.7. We then square that to get 246.49. Since we want a semicircle we cut that in half to get 123.245. We add this to 100 to get 123.245. Since we have to round, the answer is: The area of the figure is about 123 m2.
u have to subtract 26,800 by 5,000 then u would get 21800 then u find 15% of 21800 and u get 3270 John Doe paid $3,270
