y = kx is the formula for direct variation

8 = k*20

divide by 20

8/20 =k

divide by 4

2/5 =k

y = 2/5 x

Answer:

  7.28 miles

Step-by-step explanation:

Suppose the distance at closest approach is represented by x. Then the distance to the point of closest approach at the first sighting is ...

  d1 = x·tan(62°)

At the second sighting, the distance to the point of closest approach is ...

  d2 = x·tan(38°)

The difference of these distances is 8 miles, so we have ...

  d1 -d2 = 8 = x(tan(62°) -tan(38°))

Dividing by the coefficient of x, we find ...

  x = 8/(tan(62°) -tan(38°)) ≈ 7.2764 . . . . miles

The point of closest approach is about 7.28 miles from the landmark.

Yesterday morning Kathryn had 105 dollars. She first spent 1/3 of it at the mall. She counted her money. Later, she went to the
Katen [24]

Answer: she has $20 left now.

Step-by-step explanation:

The total amount of money that Kathryn had yesterday was 105 dollars.

She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is

1/3 × 105 = $35

The amount left after her shopping would be 105 - 35 = $70

Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is

5/7 × 70 = $50

The amount that she has left now is

70 - 50 = $20
