Answer:
-3/4
Step-by-step explanation:
Perpendicular slopes are reciprocal opposites of the original slope. This means that the reciprocal of 4/3 is 3/4, and the opposite of 3/4 is -3/4.
Hi!
First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is c < 4, the answer would be D, and not B.
If the answer was c ≤ 4, the answer would be B, and not D.
I hope that makes sense. Now let's solve the inequality.
Remember that whatever we do to the inequality, we have to do it to both sides.
We need to isolate c on one side.
10c + 5 ≤ 45
Start by subtracting 5 from both sides.
10c + 5 - 5 ≤ 45 - 5
10c ≤ 40
Divide by 10 on both sides.
10c/10 ≤ 40/10
c ≤ 4
The answer is B.
Hope this helps! :)

Step-by-step explanation:
Answer:the coastline is 20000 miles.
The land boundaries are 12000 miles.
Step-by-step explanation:
The length of the entire border of the Unites States is approximately 32,000 miles.
5/8 of the entire length is the coastline. It means that the length of the coastline of the U.S would be
5/8 × 32000 = 20000 miles.
Therefore, the length of the boundaries of the US would be
32000 - 20000 = 12000 miles.
