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.

romanna [79]

Answer:

A

Step-by-step explanation:

We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.

Our range is:

1600 to 1620

1610 - 10 to 1610 + 10

So the answer is 1

That means, that 68% is the answer.

How do you find the perimeter
lukranit [14]

The perimeter is 86 m.

When you add the 18 with the 11, you get the length of the bottom side, which is 29. When you add the nine and the 6, you get the length of the left side, which is 15. Now add everything together.

18 + 6 + 11 + 9 + 29 + 15 = 86 m

Hope I helped. Good luck!! : )
