Answer:
31 
Step-by-step explanation:
First type of clay required 3 cups of flour per batch 
She made 5 batches 
5 * 3 = 15 
So she used 15 cups of flour for the first type of clay 
Second kind of clay required 4 cups of flour per batches 
She made 4 batches 
4 * 4 = 16 
So she used 16 cups of flour for the second type of clay 
we now add the total number of cups of flour used for each type of clay 
16 + 15 = 31
She used a total of 31 cups of flour 
 
        
             
        
        
        
Solution:
we are given that 
In the image, shape ABCD is similar to shape WXYZ.
we have been asked to find the measure of side ZW.
As we know that when two shapes are similar then the ratios of their corresponding sides are equal.
So we can write 

Hence ZW=4.5 Inches.
