A point on the edge of the roller travels the circumference of the roller in 1 revolution, so that its linear velocity is
(10 rev/s) * (2*(14.25 cm)*pi cm/rev) = 285 pi cm/s
or about 895.4 cm/s.
D would be more logic because the total of kids playing football and hour everyday and he would be able to count for in a whole week
You find the probability of an event happening if you divide the number of times that event has actually happened in the experiment by the number of total events that has happened. If you want to find the probability of the used car, you have to know..
how many used cars were there? 15
how many cars were there? 40
Therefore, the probability of buying a used car is 15/40 or 3/8.
Answer:
Kylie's grandfather is 73 years old.
Step-by-step explanation:
Let the first digit in Kylie's grandfather's age be x, which is the age of Isaac
Let the second digit in Kylie's grandfather's age be y, which is the age of Kendra.
Therefore from the given information we can say that
(10x + y) + x + y = 83
therefore 11x + 2y = 83
Let us take x = 7 then we get 77 + 2y = 83 
y = 3
Therefore we can say Issac's age is 7
and Kendra's age is 3
and the age of Kylie's grandfather is 73.
