Answer:
Step-by-step explanation:
She has 36 yards of material.
She needs 1 1/3 + 1/6 for each place setting
1/3 + 1/6 = 1/2
She needs 1 1/2 yards of material for each setting
1 1/2 = 1.5
She has to divide 36 by 1.5. If there is anything left over, it becomes scrap to be used for her next project.
You can use the following formula
- # settings = Total material/setting length
- # settings = 36/1.5 = 24
She can make 24 settings with nothing left over.
General Idea:
In any right triangle,
1. The altitude to the hypotenuse is the geometric mean between the segments into which is separates the hypotenuse.
2. Each leg is a geometric mean of the hypotenuse and the segment of the hypotenuse adjacent of the leg.
Applying the concept:
Step 1: We need to label the given diagram and set up a proportion by comparing the similar triangles as provided in attached figure.
Setting up the proportion, we get...
