Answer:
6 mm
Step-by-step explanation:
Use the Pythagorean Theorem to solve for the unknown leg

Since we need to solve for a, we will manipulate the equation in terms of b and c → 
Here,  b = 7 mm and c =  mm
 mm
Plugging these numbers into our equation gives us  →
 → =
 =  = 6 mm
 = 6 mm

Answer:
14 is what percent of 92? = 15.22.
Step-by-step explanation:
 
        
                    
             
        
        
        
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides 
Add 3 to both sides
        
             
        
        
        
Answer:
Step-by-step explanation:
This is an incomplete problem. Other data were not given.
Given:
Profit of every sandwich = $2
Profit of every wrap = $3
x = sandwich
y = wrap
Last month:  2x + 3y = 1,470
Next month: 2x + 3y = 1,593
Based on the given equation:
Both still have the same profit. $2 for sandwiches and $3 for wraps.
The only reason why there is a difference in the total amount is the change in the number of sandwich or wrap sold in a given month.
Since, next month's total sale is higher than last month's total sale, it is safe to assume that the sale of sandwich or wrap is higher than last month's sale.
