Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
Your slope would be 3/5 because you start from one point go up 3 then cross over to the right 5 to get to the next point if you were going down and to the left it would be a negative problem instead
Answer:
#1 4) 15 boys to 40 girls #2 1) 1, 3, 4, 6 #3 1) 3/5
Step-by-step explanation:
#1 3:8 Multiply both sides of this ratio by 5 15:40
#2 1, 3, 4, 6 These statements are all true.
#3 9/15 Divide both numbers by 3 3/5
Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust.
