The model helicopter would burn 10.5 ounces of fuel in 7 1/2 minutes. You would first multiply 1.4 (1 2/5 ounces of fuel) by 7 minutes to get 9.8 ounces of fuel. Then, divide 1.4 by 2 to account for the thirty seconds of the flight ( thirty seconds is half of a minute, or 1/2) to get 0.7, add 0.7 by 9.8, and get 10.5 ounces of fuel in the process.
It’s 28 my g.
That little missing piece at the end has an area of 4. The square has an area of 16, and the other part is basically also the square, missing a piece that equals 4. The question would be 16 x 2 -4= 28 .
