Answer:
Step-by-step explanation:
6.1 / 5 ( 12b + 5 )
b = 5/6 
by substituting,
6.1 / 5 ( 12 × 5/6 + 5 )
1.22 × 15 
= <u><em>18.3</em></u>

Answer:
 
Step-by-step explanation:
A square is a  <u>shape that which all sides are equal</u>
<em>14 is one side of the square and to find the area of a square/rectangle, you do  </em><u><em>length*width </em></u>
14*14=196
 
        
             
        
        
        
The answer is 2^12 = 4096. 
Look at a tree diagram. With one spin there are two possible outcomes (branches). Every time you spin, each of the branches split into two more branches. 
With 12 spins, first there are 2 branches, then 2*2, then 2*2*2, ... In the end it's 2^12
        
             
        
        
        
Answer:
52.9 inches .
Step-by-step explanation:
Given that the triangular indentation has an area of 100 in.² and the base and height of this traingle are represented by expressions 3x and x+3 respectively . We need to find out the <u>perimeter </u>to the nearest tenth.
As we know that the area of triangle is ,
 
 
Substituting the respective values,
 
 
On using the <u>Quadratic</u><u> formula</u> , we have;

On simplifying above , we will get ,

Since sides can't be negative, therefore,

Therefore ,
Next let's find out the <u>hypotenuse </u>using Pythagoras theorem, as ;
 
 
 
 
 
 
 
 
Now we may find perimeter as ,
 
 
 
 
 
 

 
        
             
        
        
        
This would mean that she has been in school for about 1,000 days. Thus, we need to figure out the amount of days she would have went to school within the week. This would normally be 5 days within the 7. 
5/100 x 1000 is 714.28
When rounded to the nearest ten, it would end up at 710.
