Answer:
275 miles in 5 hours 
55 miles in one hour
Check
to check if im right 
275×2 would be how many miles she drove in 10 hours rght ? 275×2=550
550 miles in 10 hours 
we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550 
10 hours plus 3 hours = 13 hours right ? 
55 ×3 = 165
550 +165=715
715 miles in 13 hours 
Step-by-step explanation:
715÷13 to get how many miles she drove in one hour .
=55 miles in 1 hour .
then multiply 55 ×5 to get how many miles she drove in 5 hours 
55×5=275
275 miles in 5 hours
 
        
             
        
        
        
This is the concept of trigonometry, to solve the question we proceed as follows;
sec(x)=1/cosx
thus;
sec(205)=1/cos205
=1/-0.9063
=-1.1034
this implies that:
sec(205)<-1
        
                    
             
        
        
        
Answer: 0.28
Step-by-step explanation:
Let´s name the proportion of orders 
- with no optional features: "N"
- with one optional feature: "O"
- and the proportion of orders with more than one optional feature: "M"
<em>The sum of all of these proportions is equal to the total quantity of orders.</em>
Therefore, 
N + O + M = 1
Then, substracting N and O on each side of that equation,
the proportion of orders with more than one optional feature (M) is:
M = 1 - N - O
M = 1 - 0.38 - 0,34
M = 0.28
