if x varies directly as y and x=3 when y=15 find the value of x when y=25

Answers

Answer 1

Answer:

Step-by-step explanation:

x=5

Answer 2

Answer:

x is 5.

Step-by-step explanation:

X varies directly with y, so we can use the equation x = yk (with k standing for the constant of variation) to find what the constant is. Substitute 3 for x and 15 for y

3 = 15k

Now divide both sides by 15.

3/15 = k

3/15 simplifies to 1/5.

1/5 = k

Now that we know the constant, then what we need to do is find 1/5 of 25 to get x.

1/5(25) = x

Multiply 1/5 by 25 to get 5.

5 = x

The problem is solved.

X will be 5 in this scenario.

Answer:

  7 1/3 hours

Step-by-step explanation:

We are to assume that the total number of heater-hours required is a constant. That is, the time is inversely proportional to the number of heaters.

If the number of heaters goes up by a factor of 6/4 = 3/2, then the number of hours will go down by the inverse factor: 2/3.

With 6 heaters instead of 4, the time required is (2/3)(11 hours) = 7 1/3 hours.

∠ FEG = 50°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

110° is an exterior angle of the triangle, then

5x + 6x = 110

11x = 110 ( divide both sides by 11 )

x = 10

Then

∠ FEG = 5x = 5(10) = 50°
