There would be 8.12 feet of water after 4 hours.
Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
first we distribute the a to the 2x and -3
2ax -3a=bx+5
we move the -3a over by adding 3a
2ax=bx+5+3a
then we move the bx over
2ax-bx=5+3a
we can now group the left side like this
x(2a-b)=5+3a)
to find x all we must do is divide both sides by (2a-b)
x=(3a+5)/(2a-b)
Answer:
Step-by-step explanation:
Let x be the price increase.
<u>Then the current price is: </u>
<u>Then the number of passengers is:</u>
<u>Then the revenue: </u>
- Revenue = Price * Number of Passengers
- R = (50 + x)(8000 − 100x) =
- - 100x² + 3000x+ 400000
This is a quadratic relationship. Maximum point is obtained at vertex.
<u>Vertex is determined by x = - b/2a, find the value of x:</u>
- x = - 3000 / (-2*100) = 15
<u>The maximum revenue is:</u>
- R = (50 + 15)(8000 − 100 * 15) = 424500
3 2/11 as a decimal is 3.18
