Answer:
720
Step-by-step explanation:
Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).
  
  P(10,3)=10! / (10-3)!
= 10!/7!
Rewrite  10
!  as  
10 * 9  * 8  * 7
!  / 7!
Cancel the common factor of  7
!  and divide (
10  * 9 * 8
) by  1
10  * 9  * 8 = 720
 
        
             
        
        
        
Answer:
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
Step-by-step explanation:
Let's find out the pattern Zack is using to water his garden, this way:
First week =  1 3/8  gallons of water
Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4
Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8
The constant of adding every week is 3/8 gallons, therefore,
Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water
Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
