The side lengths of quadrilateral are 21 inches; 11 inches; 11 inches; 7 inches.

<u>SOLUTION:</u>

Given, the perimeter of a quadrilateral (four-side polygon) is 50 inches.  

Let the length of shortest side be n inches.  The longest side is three times as long as the shortest side.  

That is, length of largest side = 3n inches

The other two sides are equally long and are 4 inches longer than the shortest side.  

Then, length of remaining two sides = 4 + n inches  

We have to find the length of all four sides.

Now, we know that, perimeter = 50 inches  

\begin{array}{l}{\rightarrow \text { Sum of all sides }=50} \\\\ {\rightarrow n+3 n+n+4+n+4=50} \\\\ {\rightarrow n+3 n+n+n=50-4-4} \\\\ {\rightarrow 6 n=42} \\\\ {\rightarrow n=7}\end{array}

So, length of sides will be,

7 \text { inches; } 3\times7=21 \text { inches; } 7+4=11 \text { inches; } 7+4=11 \text { inches. }

dimaraw [331]

Answer:

y=10r

Step-by-step explanation:

Ok so if each member of the jazz band sold the same amount of tickets, r, then we can write a linear equation (no exponents or anything). let y be the total number of raffle tickets sold. If they all sold the same amount, then we can simply multiply the number of people by the tickets they individually sold.

What is the measurement of 1?
Zinaida [17]
56°

A triangle makes a total of 180°
They have already given you the 83° and you know a line makes 180° so 180-139 gives you 41°.

83+41=124
180-124=56

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
JulijaS [17]
For the manager's store

 Population size: 15
 Arithmetic mean (μ): 37.6
 Standard deviation (σ): 11,056

 For the competitor's store
 
 Population size: 15
 Arithmetic mean (μ): 48,533
 Standard deviation (σ): 28,356

 For the manager's store the average is a better representation of the data since it does not have Outlier points in the box diagram. Also the median is close to the average.

 For the competition store the average of the data collected is not as good representation of the data since they are dispersed from the mean with a standard deviation of 28.35. It also presents Outliers points in the box diagram, such as 112 which is very far from the average
