Trina brings 6 cubic yards of compost for planting the trees. Each tree needs to be planted with 1/6 cubic yards of compost
kumpel [21]
If the question is asking how many trees can be planted with 6 cubic yards of compost, here is the solution.

6 divided by 1/6 means to take 6 wholes and break them into groups the size of 1/6.

One whole can be broken into 6 groups of 1/6 (6/6), so 6 wholes can be broken into 36 groups of 1/6 (6 x 6 = 36/6).

Mathematically, you will multiply 6 by 6/1  to get the 36.

You can plant 36 trees with 6 cubic yards of compost.

The perimeter of a rectangle is 25 2/5 ft. The length is
Naya [18.7K]

Answer:

Width = 4.85 feet

Length = 7.85 feet

Step-by-step explanation:

Given:

Perimeter of a rectangle = 25 2/5 ft = 25.4 feet

Length = 3 + Width

Computation:

Assume;

Width = a

So,

Length = 3 + a

Perimeter of a rectangle = 2(l + b)

25.4 = 2[(3 + a) + a]

25.4 = 2[3 + 2a]

25.4 = 6 + 4a

4a = 19.4

a = 4.85

Width = 4.85 feet

Length = 3 + 4.85

Length = 7.85 feet
