All we really need to do here is to convert 2 cm to meters.  There are 100 cm in 1 meter, so the appropriate cm to meters conversion factor is 
1 meter
-----------
100 cm
Thus, 
2 cm       1 m
-------- * ----------- = (1/50) m = 0.02 m      or  2.0*10^(-2) m     (answer)
    1        100 cm
        
             
        
        
        
Answer:
total profit gained = 20%
Step-by-step explanation:
profit = SP - CP = 18 - 15 = 3 naira
total profit percentage =
 
-  ( profit / CP ) × 100
 -  3 / 15 × 100
 - 20%
 
hence her total percentage gain was 20%
 
        
             
        
        
        
-4/9 times -5/8 you can cross cancel the 4 and 8 so it makes the problem -1/9 times -5/2 which equals -5/18
        
             
        
        
        
Answer:
B
Step-by-step explanation:
For 11  1/2 gallons, he paid $36.80.
We need to find the cost per gallon.
First, converting 11  1/2 gallons to decimal, it is:
1/2 = 0.5
So, 11  1/2  is  11.5 gallons
So, Cost Per Gallon (last week) = 
There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.
<em>5% = 5/100 = 0.05</em>
<em>0.05 * 3.20 = 0.16</em>
<em>So,</em>
<em>3.20 + 0.16  = $3.36 per gallon</em>
<em />
Cost Per Gallon (this week) = $3.36
To buy 9  1/4 gallons it would take:

<u>Note:</u>  1/4 = 0.25, so 9  1/4 = 9.25
It would cost $31.08  to buy  9.25 gallons this week
Correct answer is B
