You're looking for the volume of the prism.  The dead giveaway there is that you're looking for "cubic" measurement.  Cubic measures are indicators that the volume is being determined, just like "square feet" or inches, etc indicates area is being determined.  The volume for this prism is found by multiplying the length times the width times the height.  In decimal form, 45×30×40=54,000.  But that is in cubic inches and we want cubic feet.  So we will use dimensional analysis to convert that.  Setting up the DA looks like this, keeping in mind that there are 12 cubic inches in 1 cubic foot:  

.  The label of cubic inches cancels out leaving us with cubic feet, and doing the division there gives us 54,000/(12*12*12) which is 31.25 cubic feet.
 
        
        
        
Answer:
<u>The correct answer is B. 1/729</u>
Step-by-step explanation:
1. Probability of any of the nine words would be randomly cited.
Using the Laplace Rule, we calculate that probability is 1/9
2. Now let's calculate the probability of any two - word phrase in specific order from those nine in the dictionary. We should remember that the probability of occurrence of two or more statistically independent events is equal to the product of their individual probabilities. So,
1/9 * 1/9 = 1/81
3. Using the same Multiplication Rule, we can calculate the probability of a random generation of the phrase "three blind mice", in that specific order. Because there are other phrases that could be generated with those three words, but in different order.  The question was specific about the order.
1/9 * 1/9 * 1/9 = 1/729
<u>The probability of randomly generating the phrase "three blind mice" is 1/729 or 0.137%</u>
 
        
             
        
        
        
Answer:
Step-by-step explanation:
x 1 = π ,  x 2 = 3 π/ 2
y 1 = - 1,  y 2 = 2
The Rate of change = ( y 2 - y 1) / ( x 2 - x 1 )=
 = [2 -( -1 )] : ( 3 π /2 - π ) = 3 : π/2 = 6 / π <em>≈ 1.91 </em>
