Answer:
The total amount of lawns to be mowed would be 20 in 35 hours.
Step-by-step explanation:
It takes an hour and 45 minutes to mow one lawn. When you multiply the 7 hours by 5 you get 35 hours. Same thing if you multiply the 4 lawns by 5 you get 20 lawns.
They are related because some of the factors of 36 overlap with 72
EX: 36 - 1,2,3,4,6,12,18
EX: 72 - 1,2,3,4,6,12,18,31
So that means 1,2,3,4,6,12,18 overlap
(a) In functional notation, you are asked for C(600).
For this, put 600 where t is in the functional notation C(t).
(b) The value multiplying 8 is 0.5 when the exponent of 0.5 is 1. That is
... t/5730 = 1
Multiplying by 5730 gives
... t = 5730
It will take 5730 years for half the Carbon 14 to be gone.
___
Or, you can recognize a fraction is 1 when its numerator is the same as its denominator. That is t/5730 = 5730/5730 = 1 when t=5730.
R:(1/3)=18
r = 18*(1/3) = 18/3 = 6
Answer: (1, -2) and (3, 0)
Step-by-step explanation: Trust me, I graphed it and these are the point where the lines intersect.
