It’s 8n-12 because it’s trying to find the difference so you would replace the and with the subtraction sign
Step-by-step explanation:
The lateral area is
The surface area is
The volume is
The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
Answer: unit rate = 1 / 5 = 0.2 inches per day
Step-by-step explanation:
The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.
1. Choose two points on the graph to find the slope
- (0,0) and (5,1)
x₁ y₁ x₂ y₂
2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.
unit rate = y₂ - y₁ / x₂ - x₁
unit rate = 1 - 0 / 5 - 0
unit rate = 1 / 5 = 0.2 inches per day
5/7, I don't know what that is as a decimal, but I hope it helps
