Really all you have to do is divide the battery life by the movie lengths. Calculator time!
(4 & 1/3) / (1 & 2/3) = (2 & 2/3)
You can watch 2 & 2/3 movies with your battery life.
Answer:
A
Step-by-step explanation:
A function can't have the same number more than once, so the answer is A since there are no repeating numbers.
First, we need to find the cost per bottle for both offers:
3 / 24 = 0.125$
4 / 36 = 0.11$
(Note: I divided 3 by 24 bc we are spreading the 3 dollars over 24 bottles. If I wanted to find the number of bottles per bottle, I would divide 24 by 3.)
The cheaper per bottle offer is 36 bottles for 4$. The only option for this is D. We can calculate the difference by subtracting 0.11 from 0.125, which is 0.014$ or 1.4¢. Hope that helps!
A=<1,-3,2> and b=<-1,3,-2>
a-3b=<1,-3,2>-3<-1,3,-2>
a-3b=<1,-3,2>-<3(-1),3(3),3(-2)>
a-3b=<1,-3,2>-<-3,9,-6>
a-3b=<1-(-3),-3-9,2-(-6)>
a-3b=<1+3,-12,2+6>
a-3b=<4,-12,8>
Answer: a-3b=<4,-12,8>
