312-170=142
142÷2=71
170+71=241
241+71=312
train A weighs 241 tons
Answer:
Yes, r and h can be changed to produce same volume by;
Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".
Step-by-step explanation:
What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.
Now, volume of a cylinder is;
V = πr²h
Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".
C is your answer because of the fact that it sets the proportion needed to answer the question which the question would be how many miles can she drive on 9 gallons of gas.
so the correct proportion is 54 x
_ _
3.5 9 ! Then your answer would be she can drive about 139 miles if she has 9 gallons of gasoline. : )
Uhh i don’t see the equation.
