Given:
The area model for
.
To find:
The value of
and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:




The complete area model is shown below.
After adding all areas of the area model, we get

Therefore, the value of
is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
The Answer Is <span>factor by grouping</span>
Y=3.4x
2*3.4=6.8
5*3.4=17
8*3.4=27.2
11*3.4=37.4
Answer:
Step-by-step explanation:
the perimeter to ABCD is 13
the perimeter to WXYZ is 32.5
the scale factor enlargement is 2.5
To solve this problem, we need to use combination which is statistical tool to determine the number of ways an event may occur. The combination to select a 5 a side team from 12 students is 792.
<h3>Combination</h3>
This a mathematical technique that is used to determine the number of possible arrangements in a collection of items where the way they're arranged does not matter.
Data;
- Number of Students = 12
- Team = 5
The combination for this would be
