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.

∠RSU and ∠USV are complementary angles

$\sf\implies{ \angle RSU + \angle USV = 90 \degree }$

$\sf\implies{ (4x-15) + 20 = 90 }$

$\sf\implies{ 4x-15+20=90}$

$\sf\implies{4x+5=90}$

$\sf\implies{4x=90-5}$

A force of 18 lb is required to hold a spring stretched 8 in. beyond its natural length. How much work W is done in stretching i

Wittaler [7]

Answer: 18.75 lb.ft

Step-by-step explanation:

Given

Force required to stretch spring 8 in. is 18 lb

it can be written

$\Rightarrow F=kx\\\Rightarrow 18=k(8)\\\\\Rightarrow k=\dfrac{18}{8}=\dfrac{9}{2}\ lb/in.$

Work done in stretching from its natural length to 10 in.

$\Rightarrow W=\dfrac{1}{2}kx^2\\\\\Rightarrow W=0.5\times \dfrac{9}{2}\times (10)^2\\\\\Rightarrow W=225\ lb.in.\ or\\\Rightarrow W=18.75\ lb.ft$
