Get the LCD (Least Common Denominator) which is the answer to 6(9)
11/6 (9)
99/54
7/9 (6)
42/54
99/54 = n + 42/54
Subtract 42/54 on both sides
57/54 = n
Simplify if possible. (divide by 3)
19/18 = n
Answer: 1. [tex]\frac{19}{18}=n[/tex]
2. x=4
Step-by-step explanation:
[tex]\frac{11}{6}-\frac{7}{9}=n[/tex] First, you have to subtract [tex]\frac{7}{9}[/tex] from both sides to have n by its self.
[tex]\frac{33}{18}-\frac{14}{18}=n[/tex] Then find the common denominator. And subtract it
[tex]\frac{19}{18}=n[/tex]
6.2-2.2=x Subtract 2.2 from both sides to have x by its self.

Find the dimensions of a cylinder of volume 17 m3 of minimal cost if the top and bottom are made of material that costs twice as much as the material for the side.
Answers
Answer:
The answer is below
Step-by-step explanation:
The volume of the cylinder with radius (r) and height (h) is given as:
Volume = πr²h
17 = πr²h
h = 17 / πr²
Let k represent the cost of the side and 2k the cost of the bottom.
The area of the side = 2πrh, hence the cost of the side = k(2πrh)
The area of the top and bottom = 2πr², hence the cost of the top and bottom = 2k(2πr²)
The total cost (T) = cost of side + cost of the top and bottom
T = k(2πrh) + 2k(2πr²)
T = 2kπ(rh + 2r²)
Put h = 17/πr²
T = 2kπ (r×17/πr² + 2r²)
T = 2kπ(17/πr + 2r²)
The minimal cost is at dT/dr = 0
[tex]\frac{dT}{dr} =0=\frac{d}{dr} [2k\pi(\frac{17}{\pi r} +2r^2)]\\\\4r-\frac{17}{\pi r^2} =0\\\\4r=\frac{17}{\pi r^2}\\\\r^3=\frac{17}{4\pi }=1.35\\\\r=\sqrt[3]{1.35}\\\\r=1.1\ m\\\\h=\frac{17}{\pi r^2} =\frac{17}{\pi (1.1)^2} \\\\h=4.42\ m[/tex]

Answer:
B 16%
Step-by-step explanation:
You add all of the numbers up you get 25 and then you multiply it by four then multiply red shirts by 4
Answer:
B. 16%
Step-by-step explanation:
First, figure out the total number of people in Emily's class. To get the total amount of people in the class, add all of the numbers together.
5+6+4+3+5+2=25
We need the percentage of people who wore a red shirt. So, we need to find the whole first (100%). To get the whole to 100%, we need to find out what to multiply by 25 to get 100. This is easy because we automatically know 25x4=100.
Because we multiplied 4 by 25, now we have to multiply 4 by the number of students who wore a red shirt. 4 people wore a red shirt, so...
4x4=16
When you put 16 over 100, it looks like this: 16/100. Percentages are out of 100, so 16% of the class wore red shirts.
Hope this helps!! Have a great day :3
How do you do these questions?
Answers
Part (a)
The equilibrium price occurs at the intersection of the supply and demand curves. See the diagram below to see how this looks. Ignore the red line and green lines for now. Those will apply for part (b).
If the price was below equilibrium, then we would have a shortage and it would lead to a pressure to push prices upward. If the price was below equilibrium, then there would be a surplus or oversupply, leading to a downward pressure in prices. So inevitably the price lands on the equilibrium if given enough time and there are no external forces acting on the market.
==============================================================
Part (b)
Let's say we have two people labeled person A and person B. If person A gets a higher education, while person B does not, then person A is likely to earn more money. Person B will see this and want to may want to earn more money as well, so that makes their demand for higher education go up. While of course this rule doesn't work for everyone, in general we'll have enough people to effectively push the demand curve to the right while the supply curve remains where it is. Check out the diagram below to see what I mean.
==============================================================
Part (c)
Refer to the diagram in part (b). We have a new demand curve which intersects the supply curve to produce a new equilibrium point with price P1 and quantity Q1. So effectively the tuition has gone up due to higher demand.
==============================================================
Part (d)
If a government provides a subsidy, then this would lower the cost of education to provide people with more opportunities to improve their earning potential. The subsidy would provide a portion of the tuition which gives the illusion of the tuition price being lowered. In a way it's like getting a grant from the government to then pay that money toward your tuition.
