Given:
scale: 3 cm : 4 m
Length 12 cm
Width 9 cm
We need to convert cm to m.
length: 12cm / 3cm * 4m = 4 * 4m = 16 meters
width: 9cm / 3cm * 4m = 3 * 4m = 12 meters
Area = length * width
Area = 16 m * 12 m
Area = 192m²
Area in cm: 12 cm * 9 cm
Area in cm: 108 cm²
cm : m ⇒ ratio format
ratio: a:b = c:d where ad = bc
108 : 192 = 12² : 16²
108 : 192 = 144 : 256
a = 108 ; b = 192 ; c = 144 ; d = 256
108 * 256 = 192 * 144
27,648 = 27,648
Answer:
Explanation:
f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3
f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2
f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6
f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2
f(7) = (7-1) • 3/2
f(7) = 6 • 3/2
f(7) = 9

Step-by-step explanation:
1st- 4
2nd- 4+15-10= 9
3rd- 9+15-10=14
4th- 14+15-10=19
5th- 19+15-10=24
6th- 24+15-10=29
7th- 29+15-10=34
8th- 34+15-10=39
9th- 39+15-10=44
10th- 44+15-10=49
11th- 49+15-10=54
12th-54+15-10=59
