Answer:
Number of full size cars = 900
Step-by-step explanation:
The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are there in both ratios , we need to make the number in the ratio for compact cars to be the same.
Multiply by 8 on numerator and denominator
Multiply numerator and denominator by 5.
Ratio of medium, compact and full size are in ratio 56,40,45.
Total number of cars =2820.
(56 + 40 + 45)x = 2820
x = 
x = 20
Number of full size cars = 
=900
When you divide, you're doing the oposite of multiplication. To know that your partical answer is going to be in the hundreds place is you follow the pattern.
2874/3=958
you take the 3 and you divide it by the last two didits of the number given (28) and that'll get you into your hundreds place.
Hope this helped! :-)

Answer:
Step-by-step explanation:
A man steps out of a plane at 4,000m of height above the ground.The point at which he jumps out of the plane would make a good reference point. However, if his acceleration is going to change as a result of him opening his parachute 2000m above the ground, a good reference point would be there. Keep in mind though, that his velocity at that instant would need to be known for it to be useful- otherwise the airplane reference point would be just as good with appropriate modeling....
