Answer:

9) The scale factor is 3/2

10) The scale factor is 4/3 and the missing length is 9

Step-by-step explanation:

9) The triangles are similar because 6/4 = 9/6 = 3/2

The scale factor is 6/4 = 3/2

10) If the rectangular gardens are similiar then the scale factor is 16/12 = 4/3

(The scale factor is always > 1)

=> 12 / x = 4/3 => 4x = 12·3 => x = 9

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 44 cm, find its area.

adell [148]

Length: w+4
Width:w
Perimeter:44
Area: L times w
P=44
44=2(w)+2(w+4)
44=2w+2w+8
44=4w+8
36=4w
w=9
L=w+4
L=9+4
L=13
Area should equal 117 cm squared

Answer:

Step-by-step explanation:

so first the equation for the situation has been given which is

194=1/2x + 2x - 16

now you can just solve since it's a linear equation

194=2.5x -16

take 16 to the other side to get

210=2.5x

solve to get x (adult price)

which is 84

remember the. child's price is 8 less

84-8=76
