Answer:
It took Peter 28 minutes and 10.82 seconds to finish the race.
Step-by-step explanation:
We have that:
 : Antonio = 28 min + 11.00 s (1)
: Antonio = 28 min + 11.00 s (1)
 : Julio = A - 0.08 s  (2)
: Julio = A - 0.08 s  (2)
 : Pete = J - 0.1 s   (3)
: Pete = J - 0.1 s   (3)
Then, the time at which Pete finished the race is:
 (4)
   (4)
By entering equations (1), (2), (3) into (4) we have:
 
            
 
 
Therefore, it took Peter 28 minutes and 10.82 seconds to finish the race.     
I hope it helps you! 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
They are also similar.
Both have 4 right angles. Both have 2 sets of parallel lines. Both have 4 equal sides.  
But I think you are supposed to answer if figure 1 is similar to figure 2 and figure two is similar to figure 3 then by the transitive property, figure 1 is similar to figure 3.
 
        
             
        
        
        
Answer:
Δ ABC and Δ DEF are similar because their corresponding sides are proportional
Step-by-step explanation:
Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios
In the two triangles ABC and DEF
∵ AB = 4 units
∵ DE = 2 units
∴ 
∵ BC = 6 units
∵ EF = 3 units
∴ 
∵ CA = 2 units
∵ FD = 1 units
∴ 
∴ 
∵ All the ratios of the corresponding sides are equal
∴ The corresponding sides of the two triangles are proportional
∴ Δ ABC is similar to Δ DEF

Step-by-step explanation:
next time you answer someone's question with a bunch of random letters just to get the points don't. It rude especially sense you have questions you want answered. Now I could be nice and help you because I know how to solve this and you obviously don't, but I'm giving you the same curtesy as you did me and writing a bunch of gibberish.
 
        
             
        
        
        
Answer:
2 real solutions
Step-by-step explanation:
We can use the determinant, which says that for a quadratic of the form ax² + bx + c, we can determine what kind of solutions it has by looking at the determinant of the form:
b² - 4ac
If b² - 4ac > 0, then there are 2 real solutions. If b² - 4ac = 0, then there is 1 real solution. If b² - 4ac < 0, then there are 2 imaginary solutions.
Here, a = 6, b = -20, and c = 1. So, plug these into the determinant formula:
b² - 4ac
(-20)² - 4 * 6 * 1 = 400 - 24 = 376
Since 376 is clearly greater than 0, we know this quadratic has 2 real solutions.
