First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59

Answer:

Step-by-step explanation:
Given that,
Speed of a toy car, v = 7.2 m/s
Radius of the circular track, v = 1.5 m
We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :

So, the centripetal acceleration of the toy car is
. Hence, the correct option is (c).
