I believe its B. Stratified because the owner had to speak to ten individuals, meaning he divided it into smaller groups.
15)
20/8 = x / 6
x = 20 * 6 / 8
x = 15
16)
18/54 = (x+4)/75
1/3 = (x+4) / 75
3(x+4) = 75
3x + 12 = 75
3x = 63
x = 21
SF = 54/18
SF = 3
17)
complement angles sum = 90
90 /18 = 5
so
5 x 11 = 55
5 x 7 = 35
smaller angle = 35 degrees
18)
ratio 4:5:9
4+5+9 = 18
sum of interior angles of a triangle = 180
180 / 18 = 10
largest angle = 10 x 9 = 90
answer
largest angle = 90 degrees
Answer:
Original side of triangle = 6 units
Step-by-step explanation:
Given:
Perimeter = 45 units
Scale factor = 2.5 (Increase)
Find:
Original side of triangle = ?
Computation:
Original Perimeter = Perimeter / Scale factor
Original Perimeter = 45 units / 2.5
Original Perimeter = 18 units
Perimeter of an equilateral triangle = 3 (Side)
18 units = 3 (Side)
Side = 6 units
Original side of triangle = 6 units
In standard form the answer will be if you go by (Ax+by=c )then I must say it's 3x-7y=9
Answer:
x= 
Step-by-step explanation:
mutiply both sides of the equation by 6
12x-2n=3
move the bariable to the right hand side and change its sign
12x=3+2n
divide both sides
x=
+1/6n
use commutative propert to reorder the terms
x= 1/6n +
and thats it, i hope this helps ya!
