The national interest rate on houses for 25 years is 4.3%. The banker wishes to test that the local interest rates are lower than the national rate. So he should use the initial data of 4.3% interest as his base data. Then he should investigate the rates of houses in the local vicinities and compare it to his base data. 
        
             
        
        
        
Answer:
S=1444.4
Step-by-step explanation:
they already gave the formula so
13 is the height, 10 is the radius
plug it in to the formula (using 3.14 for pi)
S=2(3.14)(10)^2+2(3.14)(10)(13)
S=628+816.4
S=1444.4
 
        
                    
             
        
        
        
Step-by-step explanation:
a= 16x+3-14x+15
combine like terms, 16x-14x= 2x
so, 
2x+3+15, 
15+3=18
18=2x, divide 18 by 2
x=9
b)  *open the parenthesis* -1/6 *24x = -4x
-1/6*60 = -10
-4x- (-10)= -4x+10
-4x+10+2x= -4x+2x= -2x
-2x=10 = 2x=-10 = x=-5
Cheers!
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation: 
DE*s=BA  24*s=35 s=35/24
(3x+7)35/24=6x-5
35/8x+5/24=6x-5
           -5/24    -5/24
 
        
             
        
        
        
In step one, you are supposed to add 25 to both sides, because if you just subtract, it would be -5x-50=53
