2. Sammie has 3 feet of ribbon. She is making bows for her friends that each use of 1/3 of a foot of ribbon. How many bows can she make from her three feet of ribbon?

Sammy can make 9 bows.

Step-by-step explanation:

3 feet of Ribbon

1/3 for each bow

1/3 + 1/3 +1/3  = 3/3 or 1 so she can make 3 bows out of one foot of ribbon

so if you repeat this than  you should get 9 bows out of three feet of ribbion.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
