The maximum speed of a boat at 30 feet length of water is 0.093 nautical miles/hour or knots.
<u>Step-by-step explanation:</u>
- The equation for the maximum speed, s is given by s²= (16/9)x
- where, x is the length of the water line in feet.
It is given that, the modeled equation s²= (16/9)x is used to find the maximum speed in knots or nautical miles per hour.
The question is asked to find the maximum speed when the length of the water is 30 feet.
Therefore, to find the maximum speed in 30 feet water, the given modeled equation is used. So, substitute the 30 feet in place of x.
<u>Now, calculating the maximum speed :</u>
s² = (16/9)(30)
s² = 480 / 9
s² = 53.3
Taking square root on both sides,
s = √53.3
s = 7.3
The maximum speed of a boat at 30 feet length of water is 7.3 nautical miles/hour or knots.
Answer:
6 weeks=6*7 days=42days
7/42 =1/6 =0.16667
OR
7 days=1 week
therefore 1/6=0.16667
Note that both must be in the same unit.
Answer:
10x + 5 (or if thats a 41/2 then) 10x + 42
Step-by-step explanation:
3x + 1/2 + 7x - 4 1/2
10x + 5
or if thats a 41/2
3x + 1/2 + 7x - 41/2
10x + 42
Answer:
m = 170
Step-by-step explanation:
The angles are supplementary so they add to 180 degrees
70 + m-60 = 180
Combine like terms
10 + m = 180
Subtract 10 from each side
10-10 +m = 180-10
m = 170
