We need 6.5% to a decimal so..
6.5% /100 = 0.065
$21.30 X 0.065 = 1.3845 tax on the shirt
 
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845
Answer = $22.68
        
             
        
        
        
Answer:
that no. is 20
Step-by-step explanation:
let us take that certain no. as x
so
2/5. x +2=10
2x/5 = 10-2
2x = 8×5
x= 40/2
x= 20
 
        
             
        
        
        
Answer:
$4.35
Step-by-step explanation:
The expected value of a random variable <em>X</em>, often denoted as E(<em>X</em>), indicates the probability-weighted average of all possible values/events. The general formula of expected value is
 .

n=11
 
        
             
        
        
        
Since, Maxwell wants to know how much space his globes occupies he has to find its volume.
<h3>What is a volume?</h3>
Volume is the amount of space an object or substance occupies.
Every three dimensional object occupies a space. 
Volume is measured in cubic units.
Therefore, the three dimensional object that has a width, length and height will have its volume as follows;
volume = lwh
where
- l = length
- w = width
- h = height
Therefore, the space occupied by the globe is the volume of the globe.
