ans C. the average temperature at the two resorts is about the same, but the range of temperature is different
 
        
                    
             
        
        
        
3/5 = 9/15 = 36/60
2/3 = 10/15 = 40/60
0.65 = 65/100 = 13/20 = 39/60
Therefor, the answer is 3/5, 0.65, 2/3.

Answer:
x=1/2
Step-by-step explanation:
Set up the equation: 2x-1=0
Add one to both sides. 2x=1
Divide two by both sides: x=1/2
Therefore, x =1/2, or .5
 
        
                    
             
        
        
        
Answer:
the largest angle of the field is 149⁰
Step-by-step explanation:
Given;
perimeter of the triangular filed, P = 120 m
length of two known sides, a and b = 21 m and 40 m respectively 
The length of the third side is calculated as follows;
a + b + c = P
21 m  + 40 m  + c = 120 m
61 m +  c = 120 m
c = 120 m - 61 m
c = 59 m
                          B
                      ↓            ↓  
                   ↓                          ↓
                 ↓                                       ↓
             A →  →  → →  →  → →  → →    →    →  C
Consider ABC as the triangular field;
Angle A is calculated by applying cosine rule;

Angle B is calculated as follows;

Angle C is calculated as follows;

Therefore, the largest angle of the field is 149⁰.
