In this equation, n = # of sides
Area = n * (side length)² / 4*tan (180 / n)
Area = 5 * 4² / 4 * tan (36)
Area = 80 / 4 * 0.72654

If the big gear makes 2 circles and the small gear makes 5 circles they will both be on 90 sec so it will take 90 seconds I think. My dad helped me with this one :D
Answer:
125
Step-by-step explanation:
5 cubed is literally 5 x 5 x 5
So 5 x 5 = 25
multiply 25 with 5 and you get 125 as the answer.
Answer:
50 Miles
Step-by-step explanation:
The equations would be Company A- y=40+0.30x and Company B- y=20+0.70x
When you substitute x for 50 you get A- 40+0.30(50)=40+15=55$ and for B- 20+0.70(50)=20+35=55$ therefor the total miles to be the same for both would be 50 miles.
