Answer:

a = 4

Step-by-step explanation:

Assuming you require to find the value of a

In a rhombus all the sides are congruent, thus

9a - 13 = 3a + 11 ( subtract 3a from both sides )

6a - 13 = 11 ( add 13 to both sides )

6a = 24 ( divide both sides by 6 )

a = 4

Then

XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23

Thus the sides of the rhombus are 23 units

The weight of an object on a particular scale is 145.2 lbs. The measured weight may vary from the actual weight by at most 0.3 l
joja [24]

1. Know what you're looking for:

The range is the difference between the lowest and highest values.

Your weight is 145.2 and can vary from the actual weight by maximum 0.3 lbs less or maximum 0.3 lbs more.


2. Calculate your lowest and highest values :


Lowest : 145.2 - 0.3 = 144.9 lbs

Highest : 145.2 + 0.3 = 145.5 lbs


3. Calculate the range of actual weights of the object :


145.5 - 144.9 = 0.6 lbs


--> The answer is: <u>The range of actual weights of the object is 0.6 lbs.</u>


There you go! I really hope this helped, if there's anything just let me know! :)
