Answer:
D
Step-by-step explanation:
Using process of elimination we know that it cannot be a,b or c because after you add the 2 new stamps james collected the ratio is 8:12 which cannot be 1:2 because 8 is not half, can't be B because 8 is less than 12, Also cannot be C because 8 is less than 12
 
        
             
        
        
        
Answer:  or
 or 
Step-by-step explanation:
 First, you can convert the mixed number  into a decimal number. To do this, you need to divide the numerator (which is 1)  by the denominator (which is 2) of the fraction:
 into a decimal number. To do this, you need to divide the numerator (which is 1)  by the denominator (which is 2) of the fraction:
 
 Now you must add 0.5 to the whole number part. Then:
  
 
 In order to find the ratio of cleaner to water, you must divide 1.5  cups of cleaner by 12 cups of water. 
 Therefore, the ratio is:

Answer: 18mph
Step-by-step explanation:
Given data
total distance driven = 396 miles
time driven = 8 am Tuesday to 5 pm Wednesday 
total time driven in hours = 33 hours
lunch break time = 30 min Tuesday  + 30 min Wednesday 
= 60 min 
= 1 hour
sleep time = 7 pm Tuesday to  5 am Wednesday 
= 10 hours
solution:
To find the average speed,
we are given total time driven = 33hrs.
lunch + rest time = 10hrs + 1hr
= 11hrs
total time travelled =drive time - rest + lunch time 
= 33 - 11 
= 22hrs
therefore;
average speed = distance / time traveled.
average speed = 396 / 22
average speed = 18 mph
 
        
             
        
        
        
Answer:
The answer will be D.y=-2
Step-by-step explanation:
The reflection line is the fixed line that a shape or figure is reflected across of. The problem tells you that the triangle is reflected across y=-2
