Answer: Choice D) |K| = 57
------------------------------------------------------
Explanation:
The notation |K| means "the number of items in set K". It is similar to the notation n(K). In this case, we simply add up all the values in the circle labeled K. There are four of these values which are 13, 8, 17, 19. Add up these values to get 13+8+17+19 = 57. So there are 57 items in set K.
I think( so correct me if i'm wrong).....Using the distance formula... D=Rate x Time, you alter it so that it equals time, since you want to find the number of weeks.
Time = Distance/ rate
SInce you start off at 2 and end up with 5, the total distance is 3 (I subtracted 5-2). And rate is already 12% (this is the iffy part, I'm not sure if you change the 12% in anyway.... but lets move on)
SO Time= 3miles/ 12% which is 1/4 of a week, or possibly.....
Time = 3 miles/ 0.12 which would equal 25 weeks.....
Do they give you these answers?
That is called an improper fraction.You multiply the whole numbers by the denominator and then add what is left over to get the improper fraction.
so I don't know but just use the internet
Circumference = 2 x pi x radius
27 in = 2 x 3.14 x radius
Solve for the radius
