Step-by-step explanation:
((2)(2.90))+(3.10)= $8.90
 
        
                    
             
        
        
        
First question 
Volume = height * radius*radius*3.14 
5*3*3*3.14 = 141.3 in3 
Second qustion 
 Violume = height * radius * radius * 3.14 
28*8*8*3.14= 5626.88 cm3 
So the answer is 1875.63 because it's the closest
        
                    
             
        
        
        
Answer: Statement p is false.
Step-by-step explanation:
In both cases, we need to isolate the variables:
p: -3*x + 8*x - 5*x = x
    (-3*x - 5*x) + 8*x = x
     -8x + 8*x = x
         0 = x
This will be true only for one value of x, so this is not always true, which means that the statement is false.
q: (3*x)*(5*y) = 15*x*y
let's solve the left side:
   3*x*5*y = 15*x*y
   (3*5)*(x*y) = 15*x*y
    15*x*y = 15*x*y
This is true for every value of x and y, then this statement is true.
