Question 230253: Just wondering if I did this problem right? Thank you for checking.
The city mileage is 17 mpg and the highway is 26 mpg (“kbb“, 2009). Taking this in mind, we are going to find out how many miles we can go with 50 gallons of gas, where x equals the number of miles driven.
17=x/50
17*50=x
x=850 city miles on a tank of gas equaling 50 gallons.
Check: 850÷50=17
26=x/50
26*50=x
x=1300 highway miles on a tank of gas equaling 50 gallons.
Check: 1300÷50=26

Question 230248: My question is calculating D=sqrt(2h). D representing how many miles a person can see the horizon from a height, h in feet. Find the corresponding distance you should be able to see the horizon. Include height and the calculations.
D=sqrt (2h)
D= sqrt2(800)
[D=sqrt1600]^2
D=40 miles a person can see the horizon.
I was just wondering if I did this correctly? Thank you
