a.1/15 hours
b.1 7/8 hours
c.8/15 hours
d.1/8 hours

The correct option is (b)

Step-by-step explanation:  Given that Abigail and Bailey wash dogs to make extra money. Abigail can wash all of the dogs in 5 hours and Bailey can wash all the dogs in 3 hours.

We are to find the time taken by them if they wash the dogs together.

Abigail can wash the dogs in 5 hours.

So, in 1 hour, the fraction of the dogs Abigail can wash is given by

Bailey can wash the dogs in 3 hours.

So, in 1 hour, the fraction of the dogs Bailey can wash is given by

Hence, if they work together, then the fraction of the dogs that they wash in 1 hour is given by

Therefore, the time taken by them to wash the dogs if they work together will be

Thus, option (b) is correct.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
