Answer:

  Sam is 24; his mom is 48.

Step-by-step explanation:

We can let x and y represent Sam's age and his mom's age, respectively.

  y = 2x . . . . . Mom is twice Sam's age

  y -12 = x + 12 . . . . Mom's age 12 years ago is the same as Sam's age 12 years from now

__

Substituting for y in the second equation, we have ...

  2x -12 = x + 12

  x = 24 . . . . . . . . . add 12-x to both sides

  y = 2(24) = 48

Sam is 24; his mom is 48.

Use the dchnition of similarity to solve the following problem.
sveta [45]

Answer:

  1063 ft

Step-by-step explanation:

For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.

  h/(580 ft) = (5.5 ft)/(3 ft)

  h = (5.5 ft)(580/3) ≈ 1063 ft

The height of the monument is about 1063 feet.
