Find the distance (7,-8) and (0,2)

Kobotan [32]

Answer:

d = √149 = 12.2

Step-by-step explanation:

Distance between 2 coordinates: d = √[(x2 − x1)^2 + (y2 - y1)^2]

d = √[(0 - 7)^2 + (2 - -8)^2]

d = √[(-7)^2 + (10)^2]

d = √[49 + 100]

d = √149 = 12.2

a model helicopter burns 1 2/5 ounces of fuel per minute. at that rate, how much fuel is needed for a 7 1/2 minute flight

bixtya [17]

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.

Wittaler [7]

Answer: 900m

Explanation.

There are two ways you can solve to find the number of meters waved...I’ll show you how to do both.

Plan A:
1. Find the rate of meters weaves per hour by dividing 450 meters by 6 hours. The answer is 75 meters per hour.
2. Multiply the rate per hour (75) times 12 to find how many meters are weaved on 12 hours.

Plan A Answer: 900m

Plan B:
1. Set up a proportion like the one below:
2. Cross multiply and solve for x

Plan B answer: 900m
