Answer:
Size of each group = 
Step-by-step explanation:
Total number of paint brushes = x
Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3
∴ We have, number of paint brushes in a group = 
=
this is also the same thing as saying 
×
This shows that the size of the new group is the same as the size of the original group
Answer:
<h2>
The situation involves permutation</h2><h2>
The number of arrangement is 120</h2>
Step-by-step explanation:
Given that
Algebra book=1
Geometry book=1
Chemistry book= 1
English book= 1
Health book= 1
Total number of books N = (1+1+1+1+1)= 5
Permutation is used to determines the number of possible arrangements in a set when the order of the arrangements is crucial.
Number of arrangements = N!
Number of arrangements= 5*4*3*2*1= 120
<span>(12.67 + 19.2)(3.99) / (1.36 + 11.366) = 31.87(3.99) / 12.726 = 127.1613 / 12.726 = 9.992</span>
Answer:
1=b. 2=a
Step-by-step explanation:
Since there are corresponding angles, 1 and b will be congruent, and 2 and a will be congruent.
