Answer:
Step-by-step explanation:
10 dozen is equal to 120 so ratio is 800/120 or 80/12
same ration on the other side but 200/x.Cross multiply and u get 3
Answer:
Step 1 Divide all terms by a (the coefficient of x2).
Step 2 Move the number term (c/a) to the right side of the equation.
Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.
Step-by-step explanation:

y approaches 5.
As x approaches infinity, -4^(-x) approaches 0.
0 + 5 = 5

Answer:
1st cylinder: 3541.9 square mm
2nd cylinder: 439.6 square cm
Step-by-step explanation:
![s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(12)^{2} + 2(3.14)(12)(35)\\s = 6.28(144) + 6.28(420)\\s = 904.32 + 2637.6\\s = 3541.92\\s = 3541.9](https://tex.z-dn.net/?f=s%20%3D%202%5Cpi%20r%5E%7B2%7D%20%2B%202%5Cpi%20rh%5C%5Cs%20%3D%202%283.14%29%2812%29%5E%7B2%7D%20%2B%202%283.14%29%2812%29%2835%29%5C%5Cs%20%3D%206.28%28144%29%20%2B%206.28%28420%29%5C%5Cs%20%3D%20904.32%20%2B%202637.6%5C%5Cs%20%3D%203541.92%5C%5Cs%20%3D%203541.9)
Second cylinder.
