Answer:

x = 0.6623

y = 8

Image is attached for refernce of my solution

Step-by-step explanation:

In Δ DEF

By applying pythagoras theoram,

DE = \sqrt{EF^{2} - DF^{2}  }

     =\sqrt{17^{2} - 15^{2}  }  = \sqrt{289 - 225}  = \sqrt{64}  =8

∴ DE = 8

In Δ ABC

BC = y = 12 sin 30° = 6

AC = \sqrt{3} + DE + x = \sqrt{3} + 8 + x = 12 cos 30°

⇒ 9.73 + x = 10.39

<h3>⇒ x = 0.6623</h3>

The length of a rectangular floor is 4 feet longer than its width w. The area of the floor is 525 ft^2.
andre [41]

Answer:

  • 525 = (w+4)(w)
  • 21 ft by 25 ft

Step-by-step explanation:

Let w represent the width of the floor. Then the length of the floor is (w+4) and its area is ...

  A = LW

  525 = (w+4)(w)

  w^2 +4w -525 = 0

  (w -21)(w +25) = 0 . . . . factor the above

Solutions are ...

  w = 21, w = -25

We are interested in the positive solution: w = 21.

The floor is 21 feet wide and 25 feet long.

_____

<em>Alternate solution</em>

Sometimes, when the factors aren't obvious, it works well to write an equation for the average of the dimensions. Here, we can represent that with x, and use (x-2) for the width, and (x+2) for the length. Then we have ...

  525 = (x-2)(x+2) = x^2 -4

  529 = x^2

  √529 = 23 = x

Then w=23 -2 = 21, and the length is w+4 = 25.

Answer:

The average of -2.5, 5.2, 1.7, and -0.8 is <u>0.9</u>

Step-by-step explanation:

You are taking the mean of all the values

So you would add -2.5, 5.2, 1.7, and -0.8 all together

This gives you 3.6

Then you would divide by the number of numbers per se,

Which would give you the answer: 0.9
