Answer:
1
Step-by-step explanation:
One.  For example, if we chose 5 as the number, then the multiplicative inverse would be 1/5.  Multiplying 5 by 1/5 results in one (1).
 
        
             
        
        
        
he equation of a line is written as y=mx+b where m is the slope and b is the 
y -intercept, Thus,m=23 And the y -intercept,b=1
 
        
             
        
        
        
Speed is the ditance traveled by a certain object given a certain time span. To solve this problem we need to divide the distance by the time given. Before that, the problem asked us to get the speed in terms of miles per minute and we are given a distance of 3 kilometer. We have to convert this to miles. 3km(0.6miles/km) = 1.8 miles. The speed is then 1.8/20 = 0.09mi/min. 
        
             
        
        
        
<em>Answer:</em>
The Answer is 300
<h3><em>
Step-by-step explanation:</em></h3>
The answer is 300 because if you look at the hundreds place it is 200 and as my teacher told me, if the number to the right is 5 or greater bump the number up! Since the number is eight the eight will move the two up one digit causing it to be 3 and since that number was moved up all the other numbers become zeros. 
So, your answer is 300 or 300.00
