Answer: $340
Step-by-step explanation:
To identify the cost of renting the boat for 30 hours, breakdown the 30hours into specific renting hours
i.e 30 hours = (7 hours + 10 hours + 13 hours)
Then calculate each of the renting cost based on the hour breakdown given above
- Since the Cost of renting a fishing boat is $25 per hour for the first 7 hours, then (25 x 7 hours = $175)
- For the $10 per hour for the next 10 hours, then (10 x 10 hours = $100)
- and for $5 per hour for any additional hours. (5 x 13 additional hours = $65)
Now, sum up all of the cost of the hourly breakdown
i.e 30 hours = (7 hours + 10 hours + 13 hours)
= $175 + $100 + $65
= $340
Thus, the cost of renting the boat for 30 hours is $340
The points where the 2 graphs intersect is where x = 0 and x = 2.
- 2 2
x = INT x dA / INT dA
0 0
INT dA = INT -x^2 + 4x + 3 - (x^2 + 3 ) dx = INT -2x^2 + 4x
= -2 x^3/3 + 2x^2
= 2.667 between 0 and 2
xdA = -2x^3 + 4x^2 INT xdA = -x^4/2 + 4x^3/3 = 2.667
centroid = 2.667 / 2.667 = 1 (x = 1)
Answer:
x=1
Step-by-step explanation:
We distribute the negative 5 to x minus three to get 8x-5x+15=18. Then, we cancel out the 15 by subtracting it from both sides. This leaves us with 8x-5x=3. When we subtract, we get 3x=3, and when we divide both sides by 3, we get x=1. Hope this helps :)
Answer:
Step-by-step explanation:
If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;
3/4 gallons = 15 minutes
x gallons = 60minutes
cross multiply
15x = 3/4 * 60
15x = 180/4
15x = 45
x = 45/15
x = 3/1
x = 3:1
Hence the water rate in gallons per hour is 3 gallons per hour
