In the diagram shown, what is the ratio of shaded parts to unshaded parts? 6 unshaded squares and 9 shaded squares.
For every 2 shaded parts there are 3 unshaded parts.
For every 9 shaded parts there are 2 unshaded parts.
For every 3 shaded parts there are 6 unshaded parts.
For every 3 shaded parts there are 2 unshaded parts.

For every 3 shaded parts there are 2 unshaded parts

Step-by-step explanation:

because there are 3 blue shaded and 2 white that have not been shaded

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
