Answer:
n=N-1
Step-by-step explanation:
You can start by imagining this scenario on a small scale, say 5 squares.
Assuming it starts on the first square, the grasshopper can cover the full 5 squares in 2 ways; either it can jump one square at a time, or it can jump all the way to the end and then backtrack. If it jumps one square at a time, it will take 4 hops to cover all 5 squares. If it jumps two squares at a time and then backtracks, it will take 2 jumps to cover the full 5 squares and then 2 to cover the 2 it missed, which is also 4. It will always be one less than the total amount of squares, since it begins on the first square and must touch the rest exactly once. Therefore, the smallest amount n is N-1. Hope this helps!
The answer would be (x-3y) (x-7y)
You have to group them together
Scale : 1 cm = 2.5 ft
1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft
Circumference = πD = π(1.25) = 3.93 ft
Answer: 3.93 ft
Answer:
15x 
345
x = number of hours she works
Step-by-step explanation:
First: find the inequality symbol
If she wants to earn at least 345, she wants to make 345 or more
that means you use the greater than or equal symbol ()
Next, if she makes 15 dollars an hour, x has to be the number of hours she works. The left side of the inequality would be $15* number of hours, or 15x
Thus, your inequality would be 15x 345
It's not a multiple choice answer is it?
