1,099 square inches.
formula for surface area of cylinder:
2 π r^2 + 2 π rh
π = 3.14
Use formula with given dimensions:
2 • 3.14 • 5^2 + 2 • 3.14 • 5 • 30 = 1,099
Final answer: 1,099 square inches

Have a nice day!
F(x) = (1 - 0.25)x = 0.75x
f(x) = 0.75x
g(x) = (1 - 0.2)x = 0.8x
g(x) = 0.8x
(f o g)(x) = f(g(x)) = 0.75(0.8x) = 0.6x
(f o g)(x) = 0.6x
(g o f)(x) = 0.8(0.75x) = 0.6x
(g o f)(x) = 0.6x
It does not matter which one you apply first.
So ask yourself how much would I use on 10 plants? Then take what your answer is and multiply that by 3. In this situation you would use 3 gallons of water on 10 plant. So that would mean that you would use 9 gallons of water on 30 plans. When I say this I'm assuming that you only need one of those sixes, and then the second six is a typo
Answer:
Step-by-step explanation:
1) 20 for $1.56
The unit price is
1.56/20 = $0.078
= 7.8 cents each
2) $3.78 for 6
The unit price is
3.78/6 = 0.63
= 63 cents each
3) 2 1/2 for 1 dollars
The unit price is
1/2.5 = 0.4
= 40 cents each
4) 5 at 3.9
The unit price is
3.9/5 = 0.78
= 78 cent each
5) 1 1/2 for 1.58
The unit price is
1.58/1.5 = 1.05
= 1.05 each

3x + -1y = 12
Solving
3x + -1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
3x + -1y + y = 12 + y
Combine like terms: -1y + y = 0
3x + 0 = 12 + y
3x = 12 + y
Divide each side by '3'.
x = 4 + 0.3333333333y
Simplifying
x = 4 + 0.3333333333y</span>
