Answer:
The answer to your question is 13 u²
Step-by-step explanation:
We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths  of the small triangle
                  AD² = 3² + 2²
Simplify
                  AD² = 9 + 4
                  AD² = 13
                  AD = 
Find the area of the square
Area = side x side
Area = AD x AD
Area = 
Area = 13 u²

Answer:
The price of an adult ticket it $5 
Step-by-step explanation:
To solve this, we would find the system of equations. We would set up two equations that will represent the situation. 
Let c = price per children ticket
Let a = price per adult ticket
Santo:
5c + 1a = 16.25
Hulda: 
4c + 3a = 24
5c + 1a = 16.25 -> a = 16.25 - 5c
4c + 3a = 24
4c + 3(16.25 - 5c) = 24
4c + 48.75 - 15c = 24
-11c + 48.75 = 24
        -48.75   -48.75
-11c = -24.75
/-11       /-11
c = 2.25
5c + a = 16.25
5(2.25) + a = 16.25
11.25 + a = 16.25
-11.25        -11.25 
a = 5
a = $5 , c = $2.25
 
        
                    
             
        
        
        
Answer:
The statement means that after 2 hours, there are 90 bacteria in the culture.
Step-by-step explanation:
The number of bacteria after x hours is given by the function states in the exercise. We have that f(x) will be the number of bacteria after x hours.
Which statement best describes the meaning of the equation f(2) = 90 ?
The statement means that after 2 hours, there are 90 bacteria in the culture.
