Yes the proportial relationship all increase by the same number so that would be your rate of change
        
             
        
        
        
He needs to earn ; 77.99-20= 57.99 dollars
so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars
so no of week = 57.99÷ 36= 1.6 weeks
so weeks are in natural no thus it will take him 2 weeks !!
        
                    
             
        
        
        
Answers: 0.286
Explanation:
Let E → major in Engineering
Let S → Play club sports
P (E) = 28% = 0.28
P (S) = 18% = 0.18
P (E ∩ S ) = 8% = 0.08
Probability of student plays club sports given majoring in engineering,
P ( S | E ) = P (E ∩ S ) ÷ P (E) = 0.08 ÷ 0.28 = 0.286
 
        
             
        
        
        
Step-by-step explanation:
b + 81° = 117° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
b = 117° - 81°
b = 36°
for no. 14 
The angles that are congruent to < 1 are < 4 and < 8. 
 
        
             
        
        
        
Answer:
c = √746
Step-by-step explanation:
You need to use Pythagorean Theorem (a² + b² = c²) in order to solve for the hypotenuse.
25² + 11² = c²
625 + 121 = c²
746 = c²
√746 = c
