Answer:

We want to divide 30 by it's half.

The half of 30 is 30/2 = 15

then we have: 30/15 = 2

Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.

The half of 12 is 12/2 =  6

the half of the half of 12 is 6/2 = 3

now, we wanto to divide the half of 18 by that number.

The half of 18 is 18/2 = 9

then we have 9/3 = 3

and we wanted to add this to the number previous found:

2 + 3 = 5

These triangles are scaled copies of each other.
Mariana [72]

Answer:

a. 4

b. 1/4

c. 16

d. 1/9

e. 4/9

f. 9/16

Step-by-step explanation:

The ratio of the areas is the square of the ratio of the lengths of the sides.

a. Triangles G and F

Select a side in triangle G and the corresponding side in triangle F:

side in F: 10

corresponding side in G: 5

ratio of lengths of F to G = 10/5 = 2

ratio of areas of G to F: (2)^2 = 4

b. Triangles G and B

Select a side in triangle G and the corresponding side in triangle B:

side in G: 5

corresponding side in B: 5/2

ratio of lengths of B to G = (5/2)/5 = 1/2

ratio of areas of B to G: (1/2)^2 = 1/4

c. Triangles B and F

Select a side in triangle B and the corresponding side in triangle F:

side in B: 5/2

corresponding side in F: 10

ratio of lengths of F to B = 10/(5/2) = 4

ratio of areas of F to B: (4)^2 = 16

Do the same for the other 3 pairs of triangles.

The answers are:

d. 1/9

e. 4/9

f. 9/16
