Answer:

The number of watches made is 8

Step-by-step explanation:

SO the equation is C=15n+85 where C is the total cost and N is the amount of watches

1)plug in C

385=15n+85

2)move 85 to the other side so it would become -85

385=15n+85 → 385-85=15n → 100=15n

3)divide 15 from both sides

100/15=15n/15 → 25/3=n

since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)

Determine if the conclusion of salad. Give a thorough explanation of your answer. Given segment AC is perpendicular to segment c
serious [3.7K]

The given conclusion that ABCD is a square is not valid.

Given that, AC⊥BD and AC≅BD.

We need to determine if the given conclusion is valid.

<h3>What are the properties of squares?</h3>

A square is a closed figure with four equal sides and the interior angles of a square are equal to 90°. A square can have a wide range of properties. Some of the important properties of a square are given below.

  • A square is a quadrilateral with 4 sides and 4 vertices.
  • All four sides of the square are equal to each other.
  • The opposite sides of a square are parallel to each other.
  • The interior angle of a square at each vertex is 90°.
  • The diagonals of a square bisect each other at 90°.
  • The length of the diagonals is equal.

Given that, the diagonals of a quadrilateral are perpendicular to each other and the diagonals of a quadrilateral are equal.

Now, from the properties of a square, we understood that the diagonals of a square are perpendicular to each other and the diagonals of a square are equal.

So, the given quadrilateral can be a square. But only with these two properties can not conclude the quadrilateral is a square.

Therefore, the given conclusion that ABCD is a square is not valid.
