Answer:
The weight for an object with a velocity of 12 meters per second is 600 kilograms
Step-by-step explanation:
Formula of linear momentum : p = mv 
where p is the momentum 
m = mass 
v = velocity 
 If the velocity is 16 meters per second  and the object weighs 450 kilograms
Substitute the values 

We are supposed to find the weight for an object with a velocity of 12 meters per second
So, p = 12m 
We are given that The linear momentum is a constant when the mass varies inversely of the velocity.
So,

600 = m
So,the weight for an object with a velocity of 12 meters per second is 600 kilograms

Answer:
d. C. 4; enlargement
Step-by-step explanation:
Scale factor = Ratio of one of the side length of the scale diagram to the corresponding side length of the original diagram
Side length of scale diagram = 8 units
Corresponding side length of original diagram = 2 units 
Thus:
Scale factor = 8/2 = 4
Scale factor = 4
Since it's an while number, it implies that it is an enlargement.
 
        
             
        
        
        
If they each kept the same amount of the $50 prize, then we divide $50
by 2 people, giving each of them $25 winnings.  Your question is then a
little confusing because it could be answered in two ways.  Did they
each keep $20.75 out of their $25 winnings, or did the two of them keep
$20.75 in a combined total?  Please read your question again to see
which might be the case.  I'm answering on the assumption that they each
kept $20.75.
STEP 1:
divide total prize money by 2
= $50 ÷ 2
= $25 each won
STEP 2: 
If they each kept $20.75
= $25 won - $20.75 each kept
= $4.25 each gave away
STEP 3: 
multiply amount given away by 2 people
= $4.25 * 2 people
= $8.50 total given away
ANSWER: The total given to Romy is $8.50.
Hope this helps!  :)
