Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
So, the height of the nth doll can be expressed as: 12 x 0.7^(n-1)
Example: 4th doll = 12 x 0.7^(4-1) = 12 x 0.7^3
Answer:
C
Step-by-step explanation:
open circle going to the right side means >
p>-3
Answer:
15.7 meters
Step-by-step explanation:
Applying,
s = πd∅/360°..................... Equation 1
Where s = length of the arc formed, d = diameter of the circle, ∅ = angle formed by the center of the circle, π = pie.
From the question,
Given: d = 15 meters, ∅ = 120°
Constant: π = 3.14
Substitute these values into equation 1
s = (3.14×15×120)/360
s = 15.7 meters
Hence the lenght of the arc formed is 15.7 meters
Answer:
l = 9/2 or 4.5
m = 11/4 or 2.75
Step-by-step explanation:
4l + 8m = 40
8m = 40 - 4I
m = 5 - 0.5l
5l + 2m = 28
5l + 2(5 - 0.5l) = 28
5l + (10 - l) = 28
4l + 10 = 28
4l = 18
l = 18/4 or 9/2
l = 4.5
4l + 8m = 40
4(4.5) + 8m = 40
18 + 8m = 40
8m + 18 = 40
8m = 22
m = 22/8
m = 2.75
