1 answer:

5 0

In order to calculate for the distance that Jose needs to cover to go back to where he started, just use the concept of Pythagorean theorem. First illustrate the given in triangular form. The missing side is the distance covered by Jose. To calculate for the side just get the sum of the square of the two number and then get the square root of the answer. The answer would be 5 km northwest.

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

Alchen [17]

We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.

The value of x is 5 feet.
