Answer:
Weight of Airplane will be 2416 pounds when it is carrying 64 gallons of fuel.
Step-by-step explanation:
Given:
20 gallons of fuel, the airplane weighs 2130 pounds
48 gallons of fuel, it weighs 2312 pounds
so we can say that we have 2 points of value.
Let the number of gallons of fuel be 'x'.
Eight of the airplane be denoted by 'y'.
So we can say that;
Now we know that;
weight (in pounds) of an airplane is a linear function of the amount of fuel ( in gallons) in its tank.
So we can say that;
where m⇒ slope
b⇒ intercept.
first we will find the slope:
Now we will find the intercept by substituting the values;
so we get the equation as;
Now we need to find airplane weighs if it is carrying 64 gallons of fuel(
Hence Weight of Airplane will be 2416 pounds when it is carrying 64 gallons of fuel.
The amount of people who do the hurdles:
From this 15 people, the following amount does long jump:
So the answer is 12 people.
Divide the total weight by the number of candy bars.
2 / 25 = 0.08 kilograms
Convert it to grams (1kg = 1000g)
0.08 * 1000 = 80 grams
Therefore, each candy bar weights 80 grams
Best of Luck!
