Because the distance a car travels is directly related to the time it travels, the distance varies directly with the time: d=a*t. "a" would be the constant of variation. Just substituted the given values(300 and 5) into the equation, and you would get 300=5a. Divide both sides by 5 and you get a=60. So, the constant of variation is 60

Answer:
A. car needing both repairs is the intersection, which is P(A) * P(B).
92/200 * 136/200 = 391/1250 = .3128
B. car needing an alternator and not needing new brakes is the union, which is P(A) + P(notB) - P(A and B). We solved for P(A and B) in part A.
P(A) + P(notB) - P(A and B)
136/200 + 108/200 - .3128 = .9072
Answer:
Radius = 2.
Step-by-step explanation:
We have been given equation of the circle which is
.
Now we need to find the radius of the given circle
.
To find that let's compare with the formula of the circle with standard equation of the circle
, where r is the radius.
We get 
take square root of both sides.

Hence radius of the given circle is r = 2.
