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.

The length of a rectangular deck is 4 times it’s width. If the deck’s perimeter is 30ft, what is the deck’s area?
ioda

Try this solution (note, this is not the shortest way):

1. if the given length is 'l' and the width is 'w', then according to the condition 4*l=w;

2. according to the condition the perimeter is 30 ft. Formula of the perimeter is P=2(l+w), then 2(l+w)=30;

3. if to substitute '4*l' instead of 'w', the formula of the perimeter (from item no. 2) will be as 2(4*l+l)=30 or 10*l=30 ⇒ l=3 ft. The length is 3 ft.!

4. if l=3 ft., then w=4*3=12 ft. The width is 12 ft.!

5. Area is

A=w*l; A=12*3=<u>36 ft²</u>
