The answer is B sorry i was wrong 
        
                    
             
        
        
        
h= number of hours 
m= number of miles
Formula: 4h=12m
(4 hours equals 12 miles) 
Divide 4 on each side. 
h= 3m
3 miles per hour. 
Then, convert miles to feet. And hours to minute. 
To do this simultaneously, 
Convert miles to feet and hours to minutes. 
There should be 3 "fractions" to multiply. 
The first should be the original problem:
3miles/1 hour. (3 miles per hour). 
The second should be 1 hour/60min. (1 hour per 60 min). 
The third should be 5280 ft/1 mile. (5280 feet per mile). 
The second and the third fractions are to convert miles to feet and the hours to minutes. 
 
        
             
        
        
        
Let's make an equation. T will be the number.
(T+5)/4=7
Let's multiply both sides by 4 to get T by itself.
T+5=28
Subtract 5 from both sides.
T=23
Your number is 23.
        
                    
             
        
        
        
Answer:
- Perimeter = 22*sqrt(2)
- Area = 60.5 inches
- D 
Step-by-step explanation:
Remark
You need 2 facts.
- A square has 4 equal sides. 
- It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.
That means you can use the Pythagorean Theorem.
If one side of a square is a then the 1 after it is a as well.
Formula
- a^2 + a^2 = c^2
- 2a^2 = c^2
Givens
Solution
- 2a^2 = 11^2
- 2a^2 = 121                    Divide by 2
- a^2 = 121/2                  Take the square root of both sides
- sqrt(a^2) = sqr(121/2)    
- a = 11/sqrt(2)                Rationalize the denominator
- a = 11 * sqrt(2)/[sqrt(2) * sqrt(2)]
- a = 11 * sqrt(2) / 2
<em><u>Perimeter</u></em>
P = 4s
- P = 4*11*sqrt(2)/2
- P = 44*sqrt(2)/2
- P = 22*sqrt(2)
You don't need the area. The answer is D
<em><u>Area</u></em>
- Area = s^2
- Area = (11*sqrt(2)/2 ) ^2
- Area = 121 * 2 / 4
- Area = 60.5
