Answer:
perimeter: 42 in.
Step-by-step explanation:
separate the triangle, in the smallest triangle find the missing length of that side (hypotenuse: 13, short leg: 5, long leg: ?), which is (long leg) 12 in. (a^2+b^2=c^2 then 5^2+b^2=13^2) do the same process with the other half of the triangle. and you have your answer. hope this helped :)
The diameter of the circle isfeet so that’s the diameter
Find the difference in gallons and the difference in the weights
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons
