40 is 20% if what number?
Mamont248 [21]

Answer:

200

Step-by-step explanation:

Use the ratio: 20/100 = 40/X

Simplify the ratio: 1/5 = 40/X

Cross Multiply: 1X = 200

Divide both sides by 1: 1X/1 = 200/1

Simplify: X = 200

Amelia is 5 ft tall and casts a 4-foot shadow. The two triangles formed are similar because the angle to the sun is the same. Ch
Alika [10]

The two equations that can be used to find the height are as follows:

  • 12 / 4 = h  /5
  • 5 / 4 = h  / 12

<h3>Similar Triangles</h3>

Similar triangles are not necessarily the same in size. Corresponding angles of similar triangles are congruent. The sides of similar triangle are a ratio of each other.

The tree cast a shadow of 12 ft. Let's establish the proportion base on similar triangles. The height of the tree is h. Therefore,

  • h / 12 = 5 / 4

Therefore,

h / 12 = 5 / 4

cross multiply

4h = 60

divide both sides by 4

h = 60 / 4

h = 15 ft

Therefore, the two equations that can be used to find the height are as follows:

  • 12 / 4 = h  /5
  • 5 / 4 = h  / 12
