Answer:
Step-by-step explanation:
l^2=[(7-V2)/2]^2+(9-V2/2)^2=
49-7V2+2/4+81-9V2+2/4=
49+81+4/4-16V2=
131-16V2=108.4 ft
so l=V108.4≈10.4ft
Answer:
B
Step-by-step explanation:
To answer this, we need to see the to see to the fact that they are both in the same unit before we can take the ratio.
Firstly, we know that 1 foot = 12 inches. 9 feet would this be 9 * 12 = 108 inches.
Now we are told to get the ratio of length of car to length of model.
This means 108:6 = 18:1
ANSWER

EXPLANATION
We were told that the motorist travelled 250 miles on 11 gallons of gas. This implies that,

Now we want to find how far he could go on 16 gallons.

All other things being equal, the motorist should cover more than 250 miles with 16 gallons of gas.
Recall that: If more, less divides.
This implies that,


Therefore the correct answer is C.
