Answer:
3579.6 
Step-by-step explanation:
First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is 
*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: 
*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.
Let the Length of River D be : P
Given : River C is 100 Miles Longer than River D
⇒ Length of River C = P + 100
Given : The Sum of Both Rivers is 5570 Miles
⇒ P + (P + 100) = 5570
⇒ 2P + 100 = 5570
⇒ 2P = 5570 - 100
⇒ 2P = 5470
⇒ P = 2735
⇒ Length of River D is : 2735 Miles
⇒ Length of River C is : (P + 100) = (2735 + 100) = 2835 Miles
Answer:
Step-by-step explanation:
Alright so just like the other problem we have to use ratios to find if it is parallels or not. In order for AC and DE to be parallels the sides CE and AD and DB and EB have to have the same ration. So in answer c if you do 24/22.5 you would get 1.066666667. So then to find the length of EB we subtract 24 from 40 to get 16 and then we do 16/15 to find out if the ratios are the same. And indeed they are the same both equaling 1.066666667. If you were to divide CE/AD and DB/EB none of the answers would be the same leading to c being the correct answer

A function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function 
has an inverse function if and only if there is no any horizontal line that intersects the graph of at more than one point. So the function is called one-to-one. The graph of 
is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find 
:
Finally, substitute 
:
For this problem, we can use systems of equations. I will use the variables <em>x </em> (for ice-cream) and <em>y</em> (for soda). We get the system:
2.25x+0.75y=30.00
x+y=18
Putting the second equation in terms of y, we get that y=-x+18. We can substitute this into our first equation.
2.25x+0.75y=30.00
becomes
2.25x+0.75(-x+18)=30
Solving for x, we get that x=11. This satisfies answer B.
However, if you want to check to see if this is correct, you could find y by plugging in your value of x into the first equation, then check to see if your found values satisfy BOTH equations.
2.25(11)+0.75y=30
24.75+0.75y=30
0.75y=5.25
y=7
Then we plug this into both equations to see if they are true.
2.25(11)+0.75(7)=30
24.75+5.25=30
30=30 (This is true)
x+y=18
11+7=18
18=18 (This is true).
Both equations are true, so the value for x and y are correct. We see that only answer B is supported through analyzing your work.
