Answer:
28%
Step-by-step explanation:
total percent is 100%
we could rewrite the equation as: 
48% + 24% + f = 100%
72% + f = 100%(subtract 72 on both side) 
 f = 28%
 
        
             
        
        
        
Answer:
it's 6 
Step-by-step explanation:
2*3 is 6 and I*I is i^2 which equals to 1 so overall 6
 
        
                    
             
        
        
        
So the ratio to longboard to short board is 1:4, the total of that ratio is 5. 35 ÷ 5 = 7. now we're going to take those ratios and multiply 1 × 7 = 7 and 4 × 7 = 28. Your final answer is B. to confirm your answer add 28 + 7.

f(x) = 5x²
f(10) = 5(10)²  = 5(100)  = 500
f'(x) = 10x
f'(10) = 10(10)   = 100  
Now, find the line that passes through (10, 500) and has a slope of 100
y - y₁ = m(x - x₁)
y - 500 = 100(x - 10)
y - 500 = 100x - 1000
          y = 100x - 500
