Answer: 25 miles per gallon
Answer: 2.20 miles
Step-by-step explanation:
The triathlon involves the bike race, swimming and the marathon.
You are given the distance for the marathon, the biking and the total distance.
Total distance = Swimming + Marathon + Biking
135.7 = Swimming + 23.5 + 110
Swimming = 135.7 - 23.5 - 110
Swimming = 2.20 miles
Height of the trapezoids = sqrt (17^2 - 8^2) = 15cms
base = 19 cms
(b) area of each trapezoid = 15/2 (35 + 19) = 405 cm^2
Total area painted blue = 2*405 = 810 cm^2
(c) length of the edges of one trapezoid = 35 + 19 + 2(17) = 88 cms
So one piece of sandpaper ( can sand up to 80 cm) will not be enough to sand all of the edges.
