Answer:

4/7 of his marbles aren't blue or green.

Step-by-step explanation:

1/7 + 2/7 = 3/7 marbles are either blue or green in total.

7/7 - 3/7 = you're left with 4/7 not blue or green marbles.

g. Nikki's proposed placement will light less than half of the yard.

Answer:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.

Step-by-step explanation:

The area of a triangle is (base x height) / 2, and both lights illuminate the same base and height = (60 x 38) / 2 = 1,140 sq ft

Both Dylan's and Nikki's proposed placement will lit exactly half of the yard. The yard's total area = 60 x 38 = 2,280 sq ft, which is twice the area lit by the lights.
