Jane is building eight 3-legged stools. Each leg is 1/2 yard long. She can cut the legs from wooden rods that are sold in 2-yard

jonny [76]

Answer:

$n = 6\,rods$

Step-by-step explanation:

The total of legs needed to build the stools are:

$x = (8) \cdot (3)$

$x = 24$

Likewise the total length of the legs is:

$L_{tot} = 24\cdot (0.5\,yd)$

$L_{tot} = 12\,yd$

Lastly, the quantity of rods that needed to buy is:

$n = \frac{12\,yd}{2\,\frac{yd}{rod} }$

$n = 6\,rods$

see the figure below to better understand the problem

we have that

$\begin{gathered} tan55^o=\frac{h}{250}---->\text{ by TOA} \\ \\ solve\text{ for h} \\ h=250*tan55^o \\ h=357.0\text{ ft} \end{gathered}$ <h2>The answer is 357.0 feet</h2>

9.a )Explain why plane JKL is not an appropriate

VLD [36.1K]

Answer:

I will attach the missing drawing with the answer.

9.b)

Plane JKM

Plane JLM

Plane KLM

Step-by-step explanation:

The drawing for this question is missing. I will attach it with the answer.

9.a) Plane JKL is not an appropriate name for the plane because all of three points lie in the same line.

Through a line pass infinite planes. The plane JKL doesn't define a unique plane. That's why plane JKL isn't an appropriate name for the plane.

9.b) We can name the plane using three points that don't lie in the same line.

Three possible names for the plane are :

Plane JKM

Plane JLM

Plane KLM
