Answer:
3 1/2 Pounds 
Step-by-step explanation:
2/3=4/6
4/6+5/6=9/6
30/6-9/6=21/6
 
        
                    
             
        
        
        
The commutative property implies that, the order of multiplication is not important.
 is true
 is true
Commutative property of multiplication states that:
If 
The expression is given as:

To get the commutative expression, we simply change the position of each factor in the expression.
So, some possible equivalent expressions are:



There are several other equivalent expressions.

Dr /dt = 7
A = pi r^2
dA / dr = 2pir
dA/dt = dA/dr  * dr/dt = 2pir * 7  = 14pir
when r = 12   rate of change of the area =  14*pi*12  =  168pi
            =  527.79 cm^2 / minute to nearest hundredth
        
             
        
        
        
Answer:
-4y + 20
Step-by-step explanation:
4(-y+5)
What we need to do here is get rid of the parentheses, which can be achieved through multiplication.
This is another way of saying 4 times -y plus 4 times 5.
Let's break the the parentheses down into 2 separate formulas.
4(-y) and 4(5)
Now we can multiply these two together to get -4y and +20. When combined, we get -4y +20.
 
        
             
        
        
        
*See attached picture showing the dot plots referred to
Answer:
16mm
Step-by-step Explanation:
Given the dot plot showing rainfall for Highlands storms, we can find out the median rainfall for Highlands storms by mere observing the dot plot and locating where the middle value falls within the data set that is represented on the dot plot.
Thus, we have 44 data sets that is being represented on the plot, with one dot representing one data set for rainfall. This means, since the total number of data set is even, our median lies between the 22nd and the 23rd dot or data set that is being plotted. 
From the dot plot for Highlands, the 22nd and 23rd dots are 16 and 16 respectively.
Therefore, median rainfall for Highland storms = (16 + 16) ÷ 2 = 16.
