Answer:

B. When its angles are right angles.

Step-by-step explanation:

A rhombus is a quadrilateral with all 4 sides congruent. The sides can be slanted, which would keep it from being a square. If you make all the sides of a rhombus straight vertically and horizontally so you have 4 right angles, you have a square. A square is a quadrilateral with all 4 sides AND all 4 angles congruent.

55 percent of 120 books are fictional how many are non fictional
adelina 88 [10]
55 percent of 120 is 66.

120 - 54 = 66.

66 Books are fictional

So that being said, the other part of your remaining total is 54. 54 books are non-fictional. (The above where I said 120-54). Since 120 - 66 = 54.

Answer:

k = 0.167

Step-by-step explanation:

This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.

y=number of chairs

x = time in minutes.

y = k x

4 = k * 24            Divide by 24

4/24 = k

You could leave it that way.

or you could do the division

k = 1/6 = 0.167

y = 0.167 x
