Did you ever find the answer?
Answer:
B) 3
Step-by-step explanation:
This is because they are both circles and they each have the same equation for circumference. C=2πr
So that if pi stays x 2 then the perimeter will still be 3 x as big as the smaller circle. Which means it takes 3 full turns as to turn around the perimeter.
X represents (smaller) angle 1, y represents (larger) angle 2:
180 = x + y
y = 6x + 5
180 = x + y
180 = x + (6x + 5)
180 = 7x + 5
175 = 7x
25 = x
180 = 25 + y
155 = y
the smaller angle (x) is 25 degrees.
Liniear means that they go up at a constant rate
example, every year you grow 2 inches and you started at 8 inches tall
that would be linear
but that is not the case
generally, the younger you are, the faster you grow
as you age, you don't grow as much anymore :(
so no, it is not linear
