The speed, s, that the vehicle was traveling in miles per hour can be approximated by the formula s=square root 30df, where d represents the length of the skid marks in fee and "f" represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling at a speed of 45 mph when it started skidding. If the drag factor for asphalt is 0.75 find the length of the skid marks made by the car. The skid marks made by the car were approximately___________ feet long. </span>

<span>s=square root 30df, where d represents the length of the skid marks in feet and "f" represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling at a speed of 45 mph when it started skidding. If the drag factor for asphalt is 0.75 find the length of the skid marks made by the car.
S = sqrt(30df)
45 = sqrt(30*d*0.75)
----
45 = sqrt[(90/4)d]
-----
45 = (3/2)sqrt(10d)
30 = sqrt(10d)
10d = 900
d = 90 ft.

Answer: There is no solution.
Step-by-step explanation:
1.) 1 / 5 (25) + 1 / 5 (-5a) = 4 - a
2.) 5 - a = 4 - a
3.) 5 - a + a = 4 - a + a
4.) 5 = 4
The variable a is completely removed, leaving the final answer as 5 = 4, which isn't true.
Answer:
Step-by-step explanation:
Let's base this on 100%, or 100 cars, which is 100% of the cars. If 1/4 of the 100 cars are sports cars, then we have
25 sports cars and
75 sedans
If 1/5 of the total cars are red, 20 of the 100 cars are red (since 1/5 is 20).
If 1/3 of the sports cars, of which we have 25, are red, then 25/3 of the sports cars are red.
Since we have 20 total red cars and 25/3 of them are sports cars, then the rest of them must be red sedans:
Total red cars - red sports cars = red sedans
which simplifies to
