Answer:
999
Step-by-step explanation:
Line A: 376
Line C: 376 + 178
Bus: 69
Total: 376 + 376 + 178 + 69 = 999
Answer: 999
Perform indicated multiplication on left side..
4-x+2=2x-12+3x combine like terms on both sides
-x+6=5x-12 subtract 5x from both sides
-6x+6=-12 subtract 6 from both sides
-6x=-18 divide both sides by -6
x=3
Solution :
Given :
The height of the person is 5 foot.
The height of the lamppost is 12 foot.
Speed of the person away from the lamppost = 4 ft/s
Let the distance of the tip of the shadow of the perosn to the pole at t seconds after the person started walking away from the pole be d(t).
By similarity of the triangles, we see that
.................(i)
Here x is the distance from the person to the tip of the shadow. As it is given the speed of the person is 4 ft/s, then the distance of the person from the pole 4t. So we have,
x = d - 4t .............(ii)
Putting (ii) in (i) and solving for d is
d(t) = 6.85 t
So now if we derive d(t), we will get the wanted rate of the tip of the shadow.
∴ d'(t) = 6.85 ft/s
