Which of the following is most likely the next step in the series

The correct option is D.

Step-by-step explanation:

From the given diagram it is clear that the numbers are written on the red circles and the blue circles are empty.

In options A and B, the number is written on the blue circle, therefore options A and B are incorrect.

By examining the series, it is clear that the sequence of color of circle is

Blue - Red

Red - Blue

Blue - Red

Now, we conclude that the next pair of circles must be Red - Blue.

In option C, the pair of circle is Blue - Red instead of Red - Blue, therefore option C is incorrect.

Only option is most likely the next step in the series.

Therefore the correct option is D.

okay so 15.15 *()5: +5/6

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
