Answer:
53
Step-by-step explanation:
the outer measurements are the correct one
 
        
             
        
        
        
The equation for simple interest is sated as follows:
A=P(1+rt), where A= The accrued amount, P=Principal invested, r=interest rate per year, and t=time in years.
For the amount invested to be atleast double the amount invested (like the current scenario), the inequality would be would be
A≥ P(1+rt) ---- 200≥100 (1+0.05t) ---- 2≥1+0.05t --- t≥(2-1)/0.05 --- t≥20 years
Therefore, for the amount to atleast double, $100 should be invested for atleast 20 years.
        
             
        
        
        
(x)(x2)+(−4)(x2)+−16x+4
=x3+−4x2+−16x+4
Answer:
=x3−4x2−16x+4
This is what I got hope its helpful
 
        
                    
             
        
        
        
The answer that would best tell the combination of shapes that could make a piano are: 3 cylinders and a rectangular prism
<h3>How to find the shape of a piano</h3>
The shape of a piano can be gotten from the way that the piano is built. A piano is known to have a shape that is like a chord, it also has the parts that is built like a rectangular prism.
In order to get the volume of the object, the different shapes that it has would be calculated individually using their formula.
